Latest / Saving the World From Bad Ideas / Bad Idea #28 “JAWS- aka sharks are dangerous” with Arzucan -Zuzu- Askin
Transcript
- 0:00We had sharks on planet Earth before the North Star existed.
- 0:03These are really ancient predators in many ways like
- 0:06modern dinosaurs. We've single handedly managed to
- 0:08reduce our populations to the point of some of them not going
- 0:12to not being around in the next decades.
- 0:14When I dive with some of the sharks here that are critically
- 0:17endangered, I think OK, my grandkids might not get to see
- 0:19this. If you know, we don't do the
- 0:22work now in the next 10 years. Welcome to saving the world from
- 0:26bad ideas. I'm Mark Linus and I've had a
- 0:29few bad ideas in my time. I used to go out in the night
- 0:32time to destroy GMO crops and I also posed nuclear power.
- 0:35But then when I looked at the science I found I got it wrong.
- 0:38Oops. I've learned the hard way that
- 0:40none of us are right all the time.
- 0:42So now I'm here to challenge the assumptions that we all too
- 0:44often take for granted because the future depends on us getting
- 0:48it right. Hello and welcome to saving the
- 0:50world from bad ideas. Today I'm talking with Azukan
- 0:53Askin AKA Zuzu who's an incredible conservation
- 0:58scientist currently working in the Maldives on shark
- 1:00conservation with an NGO she Co founded called Miyagu.
- 1:05Susan, I won't go through your whole CV because it would take
- 1:08pretty much a whole hour, but you know the best bits.
- 1:11I think you're a National Geographic Explorer, a graduate
- 1:14of Oxford University's Seascape College Lab HSE Class 4
- 1:18commercial diver. I don't even know what that is,
- 1:20but it sounds impressive. Anyway, that's just a few
- 1:22things. Susie, welcome to the show.
- 1:24Hi, Mark, It's good to be here. Good to see you again.
- 1:27Yeah, you too. You too.
- 1:28So I guess the, you know, we, we with the show, we do a bad idea
- 1:32and you're combating the bad idea and I guess the most
- 1:34obvious bad idea with sharks, which is your, you know, the
- 1:37main thing you work on is that is that they're scary.
- 1:40And I guess, you know, there's nobody better really I can think
- 1:45of to to teach us a bit more about why sharks are, I don't
- 1:49know, maybe they're a a not scary and BA critically
- 1:51important part of the, you know, the the marine ecosystem.
- 1:56Apparently I was doing some research on this.
- 1:57Fear of sharks actually has its own word, Galleophobia.
- 2:00You know this right, And I'll bet you do.
- 2:04So tell us a bit. Give us give us like the basic
- 2:07grounding on on sharks, shark life, as it were.
- 2:09The idea that sharks are scary is actually one of the biggest
- 2:12challenges that I face in my work as a shark conservationist
- 2:17because most people, the second I say sharks, they don't want to
- 2:19hear about their ecological importance or that some species
- 2:22are critically endangered. They just hear, Oh my God, big
- 2:24scary monster. I work and dive with sharks
- 2:27pretty much every day, including large sharks like tiger sharks,
- 2:30which are classified as the most scary, more dangerous sharks by
- 2:34some people or by media. But the reality is the complete
- 2:37opposite of what you would see on TV or in shows or even how
- 2:41the media reports. We jump down to dive with 10 to
- 2:4420 tiger sharks at one time every single day.
- 2:47And we are literally circled by them continuously during our
- 2:51dives. And there's not a not a single
- 2:53moment generally when it's when it's scary.
- 2:55And when I say we come close, we come, you know, this close to
- 2:58the sharks sometimes and it's just a normal day at work.
- 3:02It's what drew me to the Maldives, actually, because
- 3:04Maldivians are probably, I might be biased, but the best shark
- 3:07divers on the planet, I haven't been anywhere else where people
- 3:10are this happy and comfortable with them.
- 3:13I mean, a lion would not let you do what a tiger sharks you do in
- 3:17the water this close. But yeah, it is a pretty, pretty
- 3:21big, pretty resilient. That idea that seems to make its
- 3:25rounds through society across the world and is very, very hard
- 3:29to combat. So we work hard on on fighting
- 3:31that every day by bringing people in the water with them
- 3:34and by busting all these misconceptions.
- 3:38And our guests always come with their own misconceptions.
- 3:41And you know, before the dive freaking, they have a million
- 3:44questions. What if I do this?
- 3:45Will the shark eat me? And we're like, no, don't worry,
- 3:48we do this every day. You will not be eaten, we
- 3:49promise. You haven't.
- 3:52You haven't had anyone eaten yet, right?
- 3:54No, no, there are a few people I'd like to beaten by a shark,
- 3:58but no, we haven't had anyone. Yet.
- 4:01And I said like, has anyone even been bitten?
- 4:03I mean, are there any, I mean, the tiger sharks are, you know,
- 4:06pretty serious predators, aren't they?
- 4:07So you can't, you know, you don't mess about with them.
- 4:09But what, what's the actual relative, you know, relative
- 4:12risks that people are running, diving with them?
- 4:14We haven't had a tiger shark fatality in the Maldives yet,
- 4:18unlike any other place around the world.
- 4:20There's a few contributing factors to this.
- 4:22One is that most Maldivians eat fish three times a day and the
- 4:26islands are made of sand. So all the organic waste that we
- 4:29generate is thrown into the sea and has been for hundreds of
- 4:32years. Now.
- 4:34If you imagine hundreds of islands with, you know, a
- 4:36population of several 100,000 people that all eat fish, that's
- 4:41a lot of fish waste that goes in the ocean daily, which means a
- 4:44lot of food for scavenging predators like sharks.
- 4:47Tiger sharks are actually quite lazy.
- 4:50They prefer to scavenge over, you know, actively spending
- 4:53energy and hunting. And why run and swim after a
- 4:56fish when you can just stop by a local harbor where the fishermen
- 5:00discard fish every day? You know, in the hundreds of
- 5:03kilos? I actually think think it's the
- 5:05fault of Jaws the movie, but what was it sometime in the 70s?
- 5:10Certainly you you weren't born then.
- 5:12I was just about born. And I do remember seeing it and
- 5:15being absolutely terrified. And I think the strap line was
- 5:18don't, don't you'll never go in the water again or something
- 5:21like that. I mean, not really a great
- 5:23participant for for marine conservation.
- 5:27Actually, I found out the the guy who wrote the book, the
- 5:30original Jaws book, Peter eventually, it was called, died,
- 5:33died a few years ago, spent his the rest of his life pretty much
- 5:37campaigning in favour of sharks because he realized he'd done
- 5:39this awful this and Spielberg as well.
- 5:42We made the movie that they basically destroyed, you know,
- 5:45people went out killing sharks. You know, it was, it was the
- 5:48absolute opposite of what you actually want people to know
- 5:50about sharks, wasn't it? I mean, do you, do you still, do
- 5:52you still look back on Jaws as being a, as being a, you know,
- 5:56an important, important moment in, in this issue?
- 5:58Absolutely. It's it's sort of the biggest
- 6:00contributing factor to why there is this mass hysteria and panic
- 6:04around the world with regards to sharks.
- 6:06I mean, you have many countries like Australia, for example,
- 6:09that have shark control programs or shark safety barriers, you
- 6:13know, so the whole idea is keeping sharks away from people
- 6:16in the water and like barricading or seemingly
- 6:19barricading parts of the water off.
- 6:20But the reality is, you know, you never fully enclosing a
- 6:23space. So the animals are still
- 6:25obviously coming close to shore because that's what they do.
- 6:28It's where they live. And it's something that I find
- 6:31really fascinating is the contrast between the Maldives
- 6:34and other countries. So I think the Jaws effect
- 6:37hasn't really reached the Maldives in the same way.
- 6:39And I think it's because sharks are so common here that people
- 6:42didn't, didn't buy into that monster image because they see
- 6:46sharks everywhere. You go to any local island, any
- 6:48harbour, you're going to see, you know, either a large shark
- 6:52or, or a small shark and generally in very large numbers.
- 6:55And so for the people here, it's just a it's a cool movie that
- 6:59they watch, but it it hasn't sort of tapped into that primal
- 7:02instinct of fear because it's something they already know.
- 7:05But for the rest of the world, that movie really tickled that
- 7:09very primitive part of our human brain that is scared of of the
- 7:14unknown and that is scared of big predators.
- 7:15And that's something that's to, to some degree really edged into
- 7:18our DNA. You know, it's something that's
- 7:21really hard to overcome for most people that obviously don't
- 7:23interact with sharks ever. And whatever the first thing is
- 7:27you hear about an animal is the thing that you're going to
- 7:29remember. You know, it's the same with
- 7:31bears or wolves. Many people fear them.
- 7:33They're like, oh, my God, if I see a bear while hiking, I will
- 7:36be so terrified. But then, you know, people that
- 7:39live in forest areas or areas with wolves and bears, they're
- 7:41like, well, yeah. I mean, it's a, it's a wild
- 7:43animal. It's going to do what any wild
- 7:45animal does, as do lions, as do elephants.
- 7:48Elephants are way more dangerous than sharks.
- 7:51You know, an elephant will actually actively charge you,
- 7:53trying to hurt you. A shark, if that comes close,
- 7:57isn't actively trying to hurt you.
- 7:59It's either, you know, mistaking you for prey or coming to check
- 8:03you out and being curious. I've worked, you know, in the
- 8:06Maldives sort of over, you know, a span of time myself.
- 8:09I was originally hired by then President Mohamed Mashid in 2009
- 8:15as climate advisor. So I worked a bit with his
- 8:17government. And I think one of the best
- 8:18things they did was, I think it was in 2010, they they did a
- 8:21shark fishing ban for the whole country and just declared their
- 8:24whole EEZ a shark sanctuary. Tell us.
- 8:28Tell us what impact that's had on shark populations.
- 8:32For the time especially, it was a revolutionary move.
- 8:35It was the second shark sanctuary in the world after
- 8:37Palau, and to this day the only shark sanctuary at national
- 8:41scale within the entire Indian Ocean region.
- 8:45Just below us is Chagos Archipelago, the British Indian
- 8:48Ocean Territory. That's also a shark sanctuary,
- 8:50but it was just declared as a no take zone.
- 8:52So any form of sort of fishing, including sharks, is prohibited.
- 8:55Whereas the Maldive Shark Sanctuary is very specific for
- 8:58sharks. And what that did was create a
- 9:01safe haven within the region. I mean, I call it the Galapagos
- 9:04of the Indian Ocean because it is, if you look northeast,
- 9:08southwest of us, everyone is fishing sharks with the
- 9:11exception of Chagos. But Chargos is an is a military
- 9:14base. It's not in fully inhabited
- 9:15country in the same way, right? And, and that means that it's a
- 9:19really important place to ensure the survival of a lot of shark
- 9:22species for the next decades to come, especially many of the
- 9:26critically endangered species like great Hamid sharks,
- 9:29scalloped Hamid sharks, oceanic white tip sharks, some of the
- 9:32ocean giants that people, you know, travel the world to see
- 9:35and experience. And we're one of the places that
- 9:37doesn't fish them. So it really, it was a big
- 9:40symbolic gesture. But also for the populations of
- 9:43sharks back then, it meant that they were able to bounce back.
- 9:46And the numbers at the time were still higher than in other
- 9:50countries because the Maldives is a relatively small country
- 9:52that never had like massive industrial fishing in the way
- 9:55we're used to in other parts of the world.
- 9:58But now as a shark sanctuary, it meant that shark populations
- 10:01really had a chance to, to bounce back.
- 10:03And we see that on dives, you know, you go on a channel dive,
- 10:05you see hundreds of grey reef sharks.
- 10:07You come to formula. Our resident tiger shark
- 10:10population is almost at 300 Id'd individuals.
- 10:13It's the largest tiger shark aggregation in the world
- 10:16confirmed to date. And you go to any other islands,
- 10:19you know, you have leopard sharks in abundance, tiny reef
- 10:22sharks popping all over the places.
- 10:25It's, it's shark, it's a shark heaven really in many, many
- 10:28ways. So it's a remarkable place for
- 10:29for wildlife. Yeah, I mean, it was one of the
- 10:32things that I really remember just walking down a Maldivian
- 10:35beach and you'll see these little pup reef sharks, I guess
- 10:41black tips probably. And, you know, they're just a
- 10:44few feet offshore. They're, you know, fins are
- 10:47above the water and they they're so cute.
- 10:49They're like literally like, like little, you know, they're
- 10:51like dog pups. They are so cute on there.
- 10:54Super cute and they're everywhere.
- 10:56You know, it's kind of, it's like we would have birds in the
- 10:59trees. Maldives Islands just have baby
- 11:01sharks and the lagoons. And so Baby Shark will set me
- 11:04off, you know. Then you have like stupid SOG in
- 11:08your head for ages. Speaking of which, haven't you
- 11:10got a program called Mama Shark? Yes, so last year.
- 11:15You last two was 1. It's my favorite project I've
- 11:18done to date. So last year we launched A
- 11:20collaborative project between Yard or NGO and two of the local
- 11:23dive centers here in Formula to conduct the world's first free
- 11:28swimming ultrasound scans on tiger sharks.
- 11:31So normally to to scan the pregnant moms, you have to catch
- 11:34them and hook them, which is a very stressful process for the
- 11:36animal. But because of how sort of
- 11:39gentle the sharks are here and how accessible they are, we
- 11:42brought over a collaborator from the US, doctor James Slikowski,
- 11:45who has a very special ultrasound unit.
- 11:48And that's basically wireless underwater.
- 11:51So we don't need to be tethered to a cable up up on the boat
- 11:55upstairs. And yeah, basically we, it was a
- 11:58Cal ultrasound and a modified underwater housing.
- 12:01And we scanned as many of the pregnant female sharks as we
- 12:05could possibly do within the time frame that we had.
- 12:07And we confirmed that over 90% of the girls that we scanned
- 12:11were pregnant, which makes formula also the first confirmed
- 12:14to station ground for the for tiger sharks in the region.
- 12:18Very exciting. And I definitely had a moment
- 12:20where I cried underwater when I had one of the scans up, when I
- 12:23was holding the screen. And the shark we scanned was
- 12:26about four meters long. And the pups that we got on
- 12:28screen captured, they were 10 centimeters.
- 12:31They were this big. And I was underwater like in my
- 12:34mask going, Oh my God. You know, it gets so emotional
- 12:37because many of the sharks, I mean, I've only been, I first
- 12:41came here almost four years ago, but you know, some of my
- 12:44colleagues and friends and dive guys on the island, they've been
- 12:47here for over a decade and they know a lot of the sharks by name
- 12:50and they know them all. They've watched them over the
- 12:52years. So to see a friend almost and be
- 12:57pregnant and to confirm that scientifically, it was a very,
- 13:00very exciting project for all of us.
- 13:03Yeah, I think I think this has to be the coolest project we've
- 13:06ever heard about on the show. Don't you agree?
- 13:08Producer Rob? Yeah, he's he's giving us a good
- 13:12a grin. So, I mean, and also it's it's
- 13:15been you published a paper in Frontiers and Marine Science in
- 13:18the Scientific Journal. We do, yeah.
- 13:20Yeah, which I was looking at. Tell us that I don't understand
- 13:23how you ultrasound scan a shark. I mean, do you need to does the
- 13:27probe actually need to be in in contact with them?
- 13:28And these are free swimming, tiger sharks, large creatures
- 13:32swimming around in the ocean. Like literally.
- 13:34How do you do this in terms of the logistics?
- 13:37Yeah, it's not as complicated as it would sound.
- 13:39So how the diving here in Fumala is set up is that the tiger
- 13:43shark dive happens at the at the harbour entrance, which is where
- 13:47the fishermen historically and actually still to the state,
- 13:49dump their fish waste. And what the dive guides have
- 13:52started to do over the years is to take some of the tuna heads
- 13:55and hide them under rock piles, which brings us sharks in that
- 13:59are coming in anyway. And then the sharks circle
- 14:01around the rock pile and they sniff the rock pile and where
- 14:03they're occupied sort of sniffing the rock pile, trying
- 14:06to find where the where the scent is coming from.
- 14:09They're relatively still. And it gives us a few seconds to
- 14:12just hold the ultrasound probe up to their belly.
- 14:15If we can touch the belly, we get a deeper scan.
- 14:18But water also transmits part of the signal.
- 14:21So even if we're just within a few centimeters range of the
- 14:24animal, we still get a really good reading.
- 14:26And that's the joy of working on the water compared to land.
- 14:28Because on land you would definitely have to make contact.
- 14:31That being said, you know, there's a few sharks where the
- 14:33probe made contact. I think you'll see a video on my
- 14:36Instagram as well. And it's, umm, they really don't
- 14:40care. They're so occupied trying to
- 14:41find the tuna head in the rocks that it's very possible here.
- 14:45And that's because, you know, they're, they're well adapted to
- 14:49this form of diving, which has been happening for a relatively
- 14:52long time. But also because there is that
- 14:54constant sort of provisioning, but unintended provisioning
- 14:58through the discard of the fish waste.
- 15:01And we're actually planning phase two.
- 15:02So the dives and us that we worked with formula dives from
- 15:04Pelagic Divers and Miyaro are getting together now to plan the
- 15:08second stage of the of the project to do more scans,
- 15:12hopefully to be involving more dive centers as well.
- 15:15And we're very excited. It's it's a very cool, very big
- 15:19project that you know, we've all been dreaming about doing.
- 15:22And definitely one of the most exciting things to study about
- 15:25sharks is the pregnancies. And it helps a lot with busting
- 15:28the big scary monster myth because an ultrasound image is a
- 15:33very relatable thing to most people on the planet.
- 15:36And when you display sharks as mothers, not just monsters, it's
- 15:40really an amazing way to connect people with the animal in a way
- 15:43that they have never, ever thought about before.
- 15:46You know, I say, oh, I'm going to show you an ultrasound image.
- 15:47And I show the scan. I don't always say what it is.
- 15:50And people are like, oh, that's so cute.
- 15:51What is it? And I'm like, oh, it's a tiger
- 15:54shark. And they're like, what?
- 15:55Yeah, it's just like with your baby.
- 15:57It's just replace the baby shape with the shark shape.
- 16:01And so in terms of in terms of conservation and science
- 16:06communication storytelling, I think this is also one of those
- 16:08projects that has a has a big potential for shifting the way
- 16:12people see sharks through science and through data.
- 16:14Yeah, I mean, you're absolutely right.
- 16:16It's like sharks as mums with and and so they give birth to
- 16:20live, live pubs, right. Tell us a bit more about how
- 16:23like just how gestation works in, in tiger sharks.
- 16:25And you know, the, the females I believe, but I mean, they're,
- 16:29they're hanging around extremely because it's safe.
- 16:31It's a safe space and they get fed and whatever.
- 16:33But like how? How does this actually work in
- 16:35nature? Yeah.
- 16:36I mean, we don't have a scientific confirmation yet of
- 16:40why we have this large aggregation.
- 16:42So there are, you know, several very obvious factors that we
- 16:44just need to prove. I mean, one of them is the
- 16:47geography and the sort of Geo morphology of the island and as
- 16:51a pinnacle that rises from the deep.
- 16:53So we have, you know, deep water, very new trend which
- 16:55shorter with a lot of upwelling and downwelling, easy access to
- 16:59large prey populations like tuna and other schools of fish.
- 17:02And then we obviously have formula being one of the biggest
- 17:05cities of the Maldives with 11,000 residents.
- 17:08So that's a lot of fish waste going in the water.
- 17:10So very steady food supply and food source, which obviously for
- 17:14mothers that have high energy demands in that stage of their
- 17:17life where they're trying to eat for two or in our case would be
- 17:20for two. In that case, it's eating for up
- 17:21to 40. It's the perfect place for
- 17:24pregnant moms to come and come and hang out and constantly get
- 17:27their sort of additional snacks and food supply.
- 17:31But yeah, they carry for over a year or so, between 12 to 1415
- 17:38months give birth to up to 4040 pups.
- 17:42Generally speaking, the numbers vary from region to region and
- 17:45from some of the studies. And then when they're born, they
- 17:48come out as fully, fully baked little predators, ready to ready
- 17:52to hunt, ready to be completely independent.
- 17:54The mums don't look after their young, so they give life birth,
- 17:58but they're not mammals. Basically, the eggs hatch inside
- 18:01the uterus of the mother, and then there's pushed out and,
- 18:05yeah, ready to roll. It's amazing.
- 18:07We have sightings from fishermen from the northern central atolls
- 18:09of pups about, you know, this big.
- 18:12And it's amazing to see that they're born so ready for for
- 18:15their bigger life in the ocean ahead.
- 18:17What's When they're born, they're about half a meter long
- 18:20or a bit longer. Generally around like 40
- 18:23centimeters. That's when.
- 18:26And is that the case for all all of the sharks that you see?
- 18:29I've seen like these eggs, I think they used to be called
- 18:32fisherman's purses or something. Yeah, purses.
- 18:34Man, it's purse, that's it, that's it.
- 18:36So some of them also have eggs as well.
- 18:38Right, Yeah, yeah. So there's different forms of
- 18:41reproduction. So there's viviperous, which
- 18:43means live birth. There's Oval, viviperous, live
- 18:46birth, birth through eggs. Oval is egg.
- 18:49So there's also sharks that will lay eggs and then the the young
- 18:53will hatch from the eggs. So basically they're offloading
- 18:56that process that would happen on the inside to the outside.
- 18:59Like leopard sharks, for example.
- 19:01They will do that. And we also have them in the
- 19:02Maldives. They lay these cute little
- 19:04pouches with the pucks that they attach to sort of rock or sand
- 19:09or parts of the reef. And then there are sharks that
- 19:13will eat each other in the mother's womb.
- 19:14And only one pup per uterus Is balls like the sand?
- 19:18Yeah, like the sand. Tiger sharks really.
- 19:20Survival of the fittest even before.
- 19:22That well, that sorry, that's, that's not cute at all.
- 19:28That shouldn't be allowed eating each other as babies.
- 19:34I'll tell you what I'd really like to hear more about.
- 19:36It's like what the attitude just to sharks and the Maldives,
- 19:38because I know you've, you've done a lot of research of this.
- 19:40You spoke, you know, you live in a formula which is a local
- 19:43island with 11,000 people, you know, fishermen, everyone there,
- 19:46dive people and, and they, and also we, you know, we're both on
- 19:52the same WhatsApp list of the Maldives Ocean Alliance.
- 19:54Every now, every, every now and then it pings up that the
- 19:57government's trying to reintroduce shark fishing or
- 20:00they're trying to rescind the ban.
- 20:02Most recently, I think they're trying to restart a fishery of a
- 20:04particular shark called the Gulpa shark.
- 20:07So tell us like how, what, what the situation is politically
- 20:10with with shark fishing at the moment?
- 20:12Yeah, it's a great question. I mean, there's no clear cut
- 20:15answer to the Maldives perception of sharks.
- 20:18I would say the general sort of the general consensus that, you
- 20:21know, most people are really appreciative of the sharks and
- 20:23value them. The dive community definitely
- 20:25does. I mean, I don't know a single
- 20:27dive guy that doesn't love sharks.
- 20:29Forget about liking or enjoying diving them.
- 20:31Love them. Most fishermen actually very
- 20:35much respect them and understand their importance and also use
- 20:39them as sort of almost collaborators in fishing by
- 20:42following certain sharks or looking for certain species of
- 20:44shark to find a specific fish that they're looking for.
- 20:47But then of course, like in every country that has
- 20:49predators, you're going to have human wildlife conflict where
- 20:52the predators are perceived as a threat to, in this case,
- 20:56fishing. In other countries, you know,
- 20:57it's farming and there has been obviously because of the bounce
- 21:02back of shark populations after the shark fishing ban, there is
- 21:05this perception that the sharks have increased, which which they
- 21:08have, but they're basically coming back to healthier levels.
- 21:12But there's the perception that there's too many sharks and
- 21:14depredation is increasing. So sharks biting off or
- 21:18completely taking away the catch of fishermen as they're fishing.
- 21:23So there are some groups that are feeling like sharks maybe
- 21:27should be fished again because there's so many and they either,
- 21:29you know, don't like them because of the depredation or
- 21:32because they feel, well, if there's so many, we should
- 21:34benefit from them commercially. Then there's also a very large
- 21:37number of people that understand that shark fishing in any form
- 21:40wouldn't be wouldn't be good for the country.
- 21:43Galba sharks are an interesting case.
- 21:45So they're a deep sea shark species that, you know, most
- 21:48people have never heard about. They're very beautiful, big
- 21:51green eyes, very long brown, slender bodies.
- 21:54But they have incredible characteristics much more
- 21:57similar to mammals than to sharks or other fish.
- 22:00So they take up to 20 years to mature before they're able to
- 22:04reproduce. It's a very long time.
- 22:06And they only produce like 2 to 3 pups every few years, you
- 22:11know, whereas fish, they'll lay thousands of eggs and have
- 22:13thousands of offspring. Sharks, you know, between
- 22:16between 10 to 100 pups. And then in the case of gulpus,
- 22:20you have those characteristics that make them really vulnerable
- 22:22to fishing because if you catch them before they're 20 years
- 22:25old, that's one less mother that can reproduce, right?
- 22:29And, and if you start catching them in large numbers, they're
- 22:32not going to be able to bounce back fast enough because of how
- 22:35slow they reproduce. And the Galpa shark fishery here
- 22:38actually collapsed based on the fishing data that we have
- 22:42available, which is not much. And it was, yeah, it collapsed
- 22:48to the point that the liver oil export stopped.
- 22:50And then shortly after the the shark fishing ban was seduced.
- 22:54You said about liver oil experts.
- 22:55So why were why were these sharks being fished at all?
- 22:58And so this was previous to the 2010 ban, Gulpa sharks were
- 23:02targeted, that's the species for this particular product, liver
- 23:04oil. Yes.
- 23:06Uh, so gulpa sharks or many deep sea sharks in general have very,
- 23:09very large livers that take up the majority of their body
- 23:12cavity. And that the liver has a very
- 23:16sort of thick viscous oil that can be extracted by boiling the
- 23:20liver. And historically in many island
- 23:23nations, that liver oil was used to varnish boats.
- 23:25It's very waterproof, Pretty, pretty remarkable stuff really.
- 23:29And so you have old photos of Dhonis in the Maldives being
- 23:32painted with this liver oil to be waterproof.
- 23:35It was also used for medicinal purposes, wound healing
- 23:39especially. And the liver oil exports in the
- 23:42Maldives only really started because Japanese buyers started
- 23:45to show interest. But now globally, the demand for
- 23:48liver oil is going up primarily for biomedical research
- 23:53vaccines. So liver oil is found in a lot
- 23:54of vaccines and beauty products as a sort of additive and yeah,
- 23:59the luxury cosmetics industry. Vaccines, right, that's it.
- 24:03I'm anti vax in that case. If you have to use shark Cliff
- 24:05or I mean, presumably there's alternatives to all these
- 24:09things. You don't need to paint your
- 24:11Dhoni boats in the Maldives with shark liver oil.
- 24:13Now there'll be synthetic incentives and there is for for
- 24:15everything. I mean, you've seen this for you
- 24:17know all. So tell us, tell us why, like
- 24:20why this is coming back up as a as a commercial opportunity in
- 24:26this, in this in the eyes of some fishermen.
- 24:28There's there's multiple theories.
- 24:29I mean, one of one of the theories that I hear a lot from
- 24:33the local community is that, you know, this is a part of a
- 24:36political campaign promise to the communities in the north
- 24:40that had shark fishing. And then when shark fishing
- 24:42stopped, basically didn't have an income replacement like big
- 24:46tourism. So communities that ended up
- 24:48losing out because of the shark fishing ban, at least
- 24:51economically. But then it's also, you know,
- 24:56the global context of of some of the demand for these products
- 24:59really increasing in the Maldives as an ocean nation
- 25:02wanting to maximize its marine resources, which is fish and
- 25:06fish out wildlife. But you know, from for many
- 25:09countries that have such large stocks of fish, that's what
- 25:13powers the economy. And here it's very much the
- 25:15same. So there's this idea that by
- 25:18bringing back galba shark fishing, it can be a form of
- 25:20fishing that doesn't hurt tourism because it's, you know,
- 25:23not a species group that is targeted by tourists.
- 25:26There's a deep sea shark and it's a way to bring income back
- 25:30to some islands that would benefit from shark fishing.
- 25:33The catch is that A, it wouldn't be very long lasting.
- 25:36It would collapse in a few years if it takes off at all, given
- 25:39that the numbers are so low. But B is that the method used is
- 25:42basically deep set long lining or baited hooks.
- 25:46And that would also 'cause all of the other shark species that
- 25:50we do, you know, have tourism with, like hammerhead sharks,
- 25:53tiger sharks, thresher sharks to also be caught.
- 25:56But that's something that most people aren't aware of because
- 25:59they hear deep sea shark fishing and they're like, Oh yeah, that
- 26:01doesn't concern us. It's fine because most people
- 26:04don't care about deep sea sharks, unfortunately, because
- 26:07they don't have a day-to-day interaction or relation with
- 26:10them. What's the Maldives like to
- 26:11work, you know, for you as a as a woman as well, You know, do
- 26:15you have to is it quite, it's quite conservative.
- 26:17Some islands. I don't know what formulas like
- 26:19I've not I've not been there. But you know, is is it
- 26:22challenging? Is it tough or is it is it
- 26:24generally pretty relaxed? It can be challenging.
- 26:27I mean, I grew up in the Turkish culture, so I'm a lot more
- 26:31diffused to Islamic values and customs than some of my
- 26:36colleagues that didn't have much connection with the religion
- 26:38prior. But of course, on the local
- 26:40islands, we tend to dress a bit more modestly, like shoulders
- 26:44covered, knees covered when possible.
- 26:46We're only really in swimwear on the boats.
- 26:48And it's always funny because when the tourists come, they
- 26:50hope to lie on the beach in a bikini.
- 26:51And then we're like, oh, sorry to deliver the bad news.
- 26:54It's not something we do on this island.
- 26:56Some local islands have bikini beaches set aside for tourists.
- 27:01I mean, I'm not going to lie, it's hard being a woman anyway.
- 27:04Maldives has it's very hard sides, but it's also got it's,
- 27:07it's very good sides. I feel, for example, is much
- 27:10more safe here than in other countries I've worked in.
- 27:13I can, you know, walk out at night.
- 27:14I can walk around by myself. Maldivian men generally tend to
- 27:19be more reserved, so you won't really be hassled or haggled on
- 27:23the street as a woman or touched by someone overtly in public,
- 27:26which is something that, for example, happens to me in Europe
- 27:28all the time. And then once you know people in
- 27:32the community, they really sort of embrace you.
- 27:35And then once you're part of part of that group of people,
- 27:38they really have your back. So for me, I have an amazing
- 27:41group of friends and colleagues here and they really take very
- 27:45good care of me. I think the challenge is more
- 27:49sometimes the island fever with the cabin fever, you know, the
- 27:52islands are small and you know, by the time you've spent a lot
- 27:56of months here, you know every corner of the island and there's
- 27:58only so many scooter drives. You can do it within a 10 minute
- 28:01time frame before you go, OK, maybe I need to go somewhere.
- 28:07And then obviously the availability of fresh produce.
- 28:10The islands are mostly sand. Not every island is able to grow
- 28:14agriculturally. Formula is, but you know, the
- 28:17greens and the fruits that we're used to at home and as easily
- 28:20already available here or as affordable.
- 28:24And being from the Mediterranean, I sometimes do
- 28:26miss my selection of, of produce.
- 28:28But then if I choose between having Peaches and, you know,
- 28:32certain greens versus diving with sharks every day, I think
- 28:35I'm going to give up the Peaches and go diving with the sharks.
- 28:40It's basically tuna for breakfast, tuna for lunch, tuna
- 28:43Curry for dinner, isn't it? I mean, do you, do you eat tuna?
- 28:45Do you eat? Do you eat fish or I?
- 28:47Learned to eat fish here. I wasn't eating fish at all back
- 28:51home. I didn't like it as a kid.
- 28:53It was always too fishy. And that's also the first thing
- 28:56I learned in in the Maldivian language and the vehi was how to
- 28:59say this is too fishy for me. But masada magada.
- 29:04But now I eat fish. I mean if you are going to eat
- 29:07fish, this is probably one of the most sustainable places to
- 29:10do so because all the tunas pollen line court or we actually
- 29:14eat a lot of other fish here in our household like Ruby, it's a
- 29:18deep sea fish. And you know, the fisherman that
- 29:20catches them is our captain or our captain's friend, and he
- 29:24goes out with one, you know, 1 hook and line, goes out with his
- 29:29little boat, catches it, comes back to the harbour and we eat
- 29:33it within the like hour that it was caught.
- 29:37So here I eat fish when I go home.
- 29:39I probably wouldn't just because now I'm very spoiled and my
- 29:42standard says fresh fish is very high.
- 29:45My Maldivian colleagues don't eat it if it's not caught within
- 29:48the last few hours. Like if the fish was caught in
- 29:52the morning, they won't eat it in the evening.
- 29:53They're like, no, that's already too old.
- 29:55Really. I guess the, you know,
- 29:57historically didn't have refrigeration.
- 30:00Yeah, so it was always like you go to the harbour, they bring
- 30:04the catch. The second they bring the catch,
- 30:06which is generally before dinner time, you select your fish, the
- 30:09guy's king for you, go home and put it in the pan, which is what
- 30:12we do in most days here as well. You ever eat a Rolex sushi or
- 30:16sashimi? Really, I don't like the
- 30:18texture, it's too squishy. I was, I was recently with
- 30:24Sylvia Earle at a meeting in Switzerland and she's, you know,
- 30:27she's this great ocean explorer. For anyone who doesn't know, I
- 30:29think she's just passed 90. She's had a birthday and another
- 30:34and a, yeah, a National Geographic sort of heroine.
- 30:37And she doesn't eat any fish. I mean, she's basically of the
- 30:39opinion that we could stop all, all, certainly all commercial
- 30:42fishing in the oceans. And I have to say on a kind of
- 30:46intellectual level, I I agree with that.
- 30:48And it sounds like you probably do, too.
- 30:49I mean, it's different than maybe island nations where it's
- 30:52such an integral part of the culture and livelihood for so
- 30:54many people. So I'm a bit torn on that.
- 30:57I mean, should people like in in other countries?
- 30:59Should our listeners buy Maldivian tuna?
- 31:02It's a good question. I mean, ethically, you know, I
- 31:05was a vegetarian for for many, many years prior to that I was
- 31:08vegan. I still struggle a lot with
- 31:10eating fish. And I definitely can't watch it
- 31:13being killed. Like when I'm on the boat and
- 31:14the guys catch one that they're going to take home for dinner, I
- 31:17look away when they, you know, have its last seconds.
- 31:21But then in terms of sustainability, for some
- 31:24countries, it would be way more detrimental environmentally to
- 31:27not eat fish than to eat what they catch.
- 31:30Like for the Maldives to substitute the tuna, you know,
- 31:34and the Ruby and other things that they catch locally with 1
- 31:36hook in line, one pollen line to substitute that for, I don't
- 31:40know, Brazilian grown soy from the rainforest that gets shipped
- 31:43here, you know, sent here by cargo ship, which, you know,
- 31:48aside from the damage to the rainforest is also a lot of fuel
- 31:51and a lot of other production costs.
- 31:53So it's a hard 1. I don't think there's a
- 31:55one-size-fits-all approach. I do think large scale
- 31:58industrial fishing should be stopped globally because it's
- 32:03unsustainable. And it's, you know, not just on
- 32:06an environmental level, also on a human level with the amount of
- 32:11catches felt, with the amount of sort of human trafficking
- 32:15involved and all the, the fuel costs and all the international
- 32:19sort of legal implications that come with that.
- 32:23I think the, the way forward is to do sort of what the Maldives
- 32:26does, which is only artisanal fishing, only pollen line
- 32:29fishing. And even their industrial fleets
- 32:31here are, you know, men with one pollen line and it just happens
- 32:35to be 20 of them on the back of a boat.
- 32:37It doesn't. No way or shape or form compared
- 32:40to the scale of anything else that happens around the world.
- 32:43Yeah, that's a very different picture to the, you know, the
- 32:46industrial krill Fisher in the Southern Ocean, which is a
- 32:48complete, complete abomination, which we're going to be
- 32:50campaigning on soon. And also, I think, you know,
- 32:54pursaining and, you know, fish aggregated devices, all the, I
- 32:57mean, it's, it's the absolute textbook unsustainable industry,
- 33:01which increasingly we just don't need.
- 33:03I mean, there's all sorts of alternatives to fish products
- 33:05now, including hopefully cell culture for people who really
- 33:07want bluefish, tuna, you know, that won't have these, these
- 33:11incredible animals won't have to be taken out of, won't have to
- 33:14be taken out of the oceans. And, you know, as somebody who's
- 33:16been, you know, I've been diving in the Maldives and snorkeling
- 33:19and you, when you see them alive, you think these are.
- 33:22These are just incredible. Animals.
- 33:25We had a guest once who saw a tuna on a dive, and he genuinely
- 33:28was convinced it was a shock because it was so big.
- 33:30And we're like, that was a tuna. It's really we're like, yeah,
- 33:33it's like, it's huge. I'm like, yes, if you don't
- 33:35catch them young, they can grow to enormous sizes.
- 33:38You just got back from Tonga recently.
- 33:40I think you actually was Speaking of Sylvia.
- 33:42Earl, what you on a boat in Tonga with Sylvia and various
- 33:46other people doing something with Wales?
- 33:48Tell me more about that. Yeah, so I was invited to be one
- 33:53of the lead scientists for a very special project in Tonga
- 33:59with the humpback whales working together also with the Lord
- 34:02Speaker of the Tongue in Government, Lord for Governor,
- 34:05Doctor Sylvia Earl and then Keith Toughly who we all know
- 34:08from Vilal Institute, who was the expedition lead for this
- 34:10project. And it was a multi method sort
- 34:14of research and storytelling initiative through which we hope
- 34:18to raise awareness for humpback whales, their remarkable journey
- 34:23of recovery, but also the upcoming challenges that are
- 34:27still facing them. While also conducting data
- 34:31collection on the local humpback whale populations of Tonga
- 34:34through DNA sampling. So collecting water samples to
- 34:36look at tiny bits of DNA shed by all living organisms to get a
- 34:40baseline hopefully of the ecosystem there.
- 34:43Collecting humpback whale skin samples, which was my favorite
- 34:46part of the of the work. I love all those nitty gritty
- 34:49bits to analyze a microbiome on the whale's skin.
- 34:53So the tiny bacterial communities that live there,
- 34:55which tell us a lot about their health, and also little bits as
- 34:59a proxy of where they've been. And hopefully, if possible, also
- 35:03to do a genetic analysis, so to be able to cross mesh DNA from
- 35:06the skin samples, if possible, if the quality of the sample is
- 35:09good enough with some of the photos and flu cuties that we've
- 35:12collected to identify individual humpback whales.
- 35:15So the idea was to contribute new knowledge and new data to
- 35:20ongoing research efforts, but also hopefully to show the
- 35:23viability of some of these really low cost methodologies to
- 35:27study these amazing animals. We also did acoustic monitoring
- 35:30to collect recordings of vocalizations.
- 35:34And yeah, although it was an amazing project and it was an
- 35:37honor to work alongside Sylvia, to spend so much time with her
- 35:41to to share the waters with her and mostly really to learn from
- 35:47her and from her wisdom. You know, she's overcome huge
- 35:51challenges. So to be able to ask her the odd
- 35:53question here and there and go, how did you do that?
- 35:56What's the challenge? What's the key?
- 35:57How do you do it was was amazing.
- 35:59Yeah, I'm, I met Lord Fakafanua at New York Climate Week and we
- 36:04we talked about you and the project and yes, Doctor Sylvia
- 36:08will be has to be a guest on on the show pretty soon.
- 36:11She's agreed. So it's only a matter of time
- 36:13until we can pin her down because she's such a such a busy
- 36:16person doing a. Busy lady.
- 36:20But, you know, talk you, you talk about whales and sharks and
- 36:23the crossover. What about whale sharks?
- 36:25They're they're, you know, something that people go to the
- 36:28Maldives to see. I've never seen one alive.
- 36:31I thought I've never seen one at all alive or dead.
- 36:33I mean, do you, do you see them? And tell us a bit about the
- 36:36conservation work for whale sharks.
- 36:38Yeah, so they actually were the species that brought me to the
- 36:41Maldives back in the day, young in my younger days when I was a
- 36:44master's student, I was in touch with the Maldives whale shack
- 36:48research program that then provided me with a data set to
- 36:52do my master's thesis. And then I came to the Maldives
- 36:56to volunteer for them and spend some time in the wooden on the
- 36:59boat with them as well. And now one of my best friends,
- 37:01actually Chloe is sort of Co running all of the research
- 37:05programs. So our group Miata doesn't work
- 37:08on wheel shacks because it's not a predatory shacks.
- 37:11So we really came up to fill that gap in the NGO landscape.
- 37:15As you know, every big megafauna species has its own NGO.
- 37:18In the Maldives, Manta Trust is the Mantas whale shark Program
- 37:22is the whale sharks, Olive Ridley does the turtles, the
- 37:25corals have a few groups. And then there wasn't a national
- 37:29level NGO for predatory sharks. So everything that's not a whale
- 37:32shark. And that's part of why Miyado
- 37:35was founded and started. But the Whale Shark Research
- 37:39program has been doing amazing, amazing research work here,
- 37:41mostly in South Ahri for the for the initial years studying the
- 37:46aggregation there, which is predominantly juvenile males.
- 37:50And then since then they've branched out to other atolls and
- 37:52islands as well. They regularly come to formula
- 37:54every year to study the whale sharks here.
- 37:57And we generally get large adult females, which we don't see very
- 38:01often in other parts of the Maldives when we see how.
- 38:07How big is large? Large, like fully grown, like
- 38:1012/13/14 and plus meters, big whale sharks.
- 38:16I had a dive with my colleague Ricky, and it was just the two
- 38:19of us and we got surprised by a whale shark just under us.
- 38:23And we looked at each other and we just couldn't believe it.
- 38:25And that thing was almost the size of our entire house.
- 38:29So incredible and just so big and makes you feel tiny and it
- 38:35makes all your problems with tiny.
- 38:37Yeah, and they just see plankton, don't they?
- 38:39Yeah, filter feeding and. And I mean, they're not haunted
- 38:43anywhere, presumably. So do they have conservation
- 38:45challenges as well? Yeah.
- 38:47The biggest conservation challenge is tourism, so the
- 38:50amount of people wanting to swim with the whale sharks and the
- 38:54amount of operators going to one specific whale shark and putting
- 38:59all the guests in the water to swim with one whale shark.
- 39:01You know, sometimes you have 2030 forty people in the water
- 39:04at once. Vessel strikes, you know, they
- 39:07feed on the surface, so they're very vulnerable to boats driving
- 39:10over them and causing a lot of propeller injuries.
- 39:13So that's a really big issue. There's like the majority of
- 39:17whale sharks cited in South area at all at one point had
- 39:20propeller strike injuries of different shapes and sizes.
- 39:24But then also climate change, which, you know, we don't know
- 39:27very much about, but how changes in the water temperature affect,
- 39:31you know, plankton and all the other little things that they
- 39:34eat, how that shifts around and if that means that they're going
- 39:38to be going to other parts of the country to feed or to
- 39:42reproduce, we don't really know. It's sort of one of the big, big
- 39:46questions that was also still unanswered for many sharks.
- 39:48Not just for the Sharks. What about?
- 39:50What about great whites? You know, everyone's favorite
- 39:53cute shark? Cute.
- 39:53Cuddly. Type of shark.
- 39:55I wish we had them here. I would love nothing more than
- 39:59to be in the water with one. I mean, they're declining
- 40:03globally at a very sort of fast rate, not as fast as some of the
- 40:08other critically endangered species, but you know, South
- 40:11Africa has lost its great wild shark populations.
- 40:14Everybody likes to blame the orcas, but another very big
- 40:16contributing factor is fishing. If you remove all the mid level
- 40:19predators, there's not much to eat for the apex predators.
- 40:24And that's the case globally with, you know, large scale
- 40:26industrial fishing basically hoovering up everything.
- 40:30You need big stuff in the water to sustain the really, really
- 40:33big stuff up top in the food chain.
- 40:35Why? What do great whites naturally
- 40:37eat? Large fish are the sharks seals.
- 40:42Yeah, yeah, there's a theory, isn't there, that orcas were
- 40:45targeting them for their livers or something because they're
- 40:47seeing great whites with bites taken out of them on the beach.
- 40:49I mean, that that's true, right? But it's obviously not not not
- 40:52an actual serious threat to their populations.
- 40:55It's true, but it's it's not sort of a giant population level
- 40:59threat. I mean, two orcas can only eat
- 41:01so many great white sharks, but large fishing feeds can take
- 41:04out, you know, thousands, if not millions of smaller sharks and
- 41:07hence remove the entire sort of food base layer that that these
- 41:13great whites and other bigger predators depend on.
- 41:16It's all linked to each other. You know you right.
- 41:18So what? What's the population level
- 41:22latest assessment of sharks globally?
- 41:24Then I remember reading a paper and maybe science or something
- 41:27that the shark population fallen by 90% or something really
- 41:31depressing like and that was a few years ago.
- 41:34What's the What's the latest data that you're seeing?
- 41:37So there's been a 71% global decline in oceanic shark
- 41:41populations. That's the overall, like, sort
- 41:44of global population estimate if you look at specific species,
- 41:48yeah, for some, it's up to 90 or again, over 90%.
- 41:52Many, many species are now critically endangered, like, for
- 41:55example, great hammerheads, scalloped hammerheads, oceanic
- 41:57white tips. And some of these sharks have
- 41:59had like local or regional extinctions of complete
- 42:04population collapses, Like they're parts of the world where
- 42:06oceanic white tips are thought to have declined by over 98%.
- 42:11It's a, it's a serious, it's, it's crazy.
- 42:14It's very crazy when you think about the fact that sharks has
- 42:16been around longer than trees. The sharks are older than the
- 42:19North Star. We had sharks on planet Earth
- 42:22before the North Star existed. And now we've wiped out the
- 42:26majority of them. You know, these are really
- 42:27ancient predators in many ways, like modern dinosaurs.
- 42:31And we've, we've single handedly managed to reduce our
- 42:34populations to the point of some of them not going to not being
- 42:37around in the next decades. And that's something I'm really
- 42:40scared of. You know, when I dive with some
- 42:42of the sharks here that are critically endangered, I think,
- 42:44OK, my grandkids might not get to see this if, you know, we
- 42:48don't do the work now in the next 10 years.
- 42:51And that's pretty scary to think about.
- 42:53So I try not to think about it too much.
- 42:55But it is sad. It's very, very sad.
- 42:57Yeah. Because there were sharks at the
- 42:59same time as the dinosaurs. So they've been around for
- 43:00hundreds of millions of years, right?
- 43:01And the idea that they could cease to exist globally, some of
- 43:05these species in, in, in, in a decade or two is, is frankly
- 43:09doesn't bear thinking about. But I, I, I assume that things
- 43:11are getting better, but it doesn't sound like it.
- 43:13Is there. Like what, what can people do as
- 43:16individuals? I'm, I don't imagine many
- 43:17listeners to this show are sitting down to bowls of shark
- 43:21fin soup, assuming that's still a thing.
- 43:23Like what are, what are they? What can anyone do as an
- 43:26individual? Yeah.
- 43:28I mean, it completely depends what part of the world you live
- 43:31in. If you live in Europe, the
- 43:33biggest thing you can do is to support all the ongoing work to
- 43:36stop shark finning and shark fishing in Europe.
- 43:39Because most people don't know. But Spain and a few other
- 43:41countries are some of the world's top exporters for shark
- 43:45fins and shark meat. A lot of fish and chips.
- 43:48In the UK is shark meat, a lot of fish and chips and.
- 43:54I mean I try not to do fish and chips but like I thought it was
- 43:56cod and haddock. How can it possibly be shark
- 43:58meat? It's usually there's been AI
- 44:01have to pull up the study for you.
- 44:02There was a really amazing study showing that the a lot of fish
- 44:05and chips in the UK is shark. It's just sort of smaller shark
- 44:08species that are just classified as white fish.
- 44:12Yeah, yeah. Like rock salmon, for example.
- 44:14Like there's all these code words, but actually it's it's
- 44:17shark flake. If you eat flake, flake is a
- 44:20shark. Wow.
- 44:21So I didn't know, I had no idea that Europe was was a was a
- 44:25major villain on this. And that's something we should
- 44:27we should definitely look into and campaign on for as as we
- 44:30plan it. So the these shark sharks
- 44:33targeted like directly purpose purposefully by fishing European
- 44:38fishing fleets. Yeah, generally.
- 44:40So particularly in Spain, they're targeted for fins and
- 44:42meat and a lot of that can then get exported to Asia.
- 44:46But also they end up a lot as bycatch, obviously, and then
- 44:49still get processed pet food, cosmetics, fertilizer for your
- 44:54garden and a lot of other everyday products that we take
- 44:57for granted. Have shark.
- 44:59There's actually a project I'm working on at the moment.
- 45:02I run a a separate project to me out called Anthropocene.
- 45:06So the human ocean and Anthropocene.
- 45:09Yeah, it's a word play on the Anthropocene.
- 45:12No, it's great. Now I like.
- 45:13It Yeah. And the idea is to really show
- 45:16how human societies intersect with the ocean, but in ways that
- 45:19we don't normally think about. And, you know, since I love
- 45:21sharks, very obviously, currently working on a little
- 45:24bit of a project to highlight how humans and sharks intersect
- 45:28in ways you wouldn't think. And I say to everyone I meet,
- 45:30you probably have had a shark in your life today without
- 45:34realizing either in your skin care, in your vaccine, on your
- 45:38plate, in your cosmetics or in your garden and many other
- 45:41things. So the key thing people can do
- 45:44is depending on where they live locally, supporting any
- 45:47initiative working for shark protection.
- 45:50The best thing you can do is to support shark protection in your
- 45:52country. And then the more countries we
- 45:54can get collectively, the more power we have globally to check
- 45:59your cosmetics for squalene, it's a shark derived ingredient.
- 46:02And then if you have squalene, either swap your cosmetics or
- 46:06message the brand and ask them to swap that for a plant based
- 46:09alternatives. And then the same also checking
- 46:13your pet food and lobbying your pet food providers to not have
- 46:17shark because I don't really want to be feeding shark to my
- 46:19cat or my dog and I. Had no idea that that pet food
- 46:24would have shark in it or or anything else.
- 46:26I mean I bought some plant based shower Jelly other I thought
- 46:29why? Why would this be plant based?
- 46:30Like what could it have in it? It's not a plant, but if you
- 46:33need a non plant based one might have shark in it for goodness
- 46:35sake. Yeah, yeah, yeah.
- 46:37It's pretty. It's pretty crazy to think
- 46:38about. Also, biomedical research.
- 46:40A lot of sharks being harvested for Cancer Research, for
- 46:43Alzheimer's Research. What's that about?
- 46:46I don't get. I've never heard of this.
- 46:48So because sharks are so ancient, you know, their DNA
- 46:53and, and sort of their entire bodies are basically archives of
- 46:58evolutionary information and evolutionary success and
- 47:01resilience, really. And for the longest time, people
- 47:03thought that sharks can't get sick or sharks can't get cancer.
- 47:07And a lot of these beliefs, and mostly due to a lack of more
- 47:10targeted science on these topics, led to sharks being
- 47:13harvested and sort of being put under the microscope for some of
- 47:17this research. There's, Yeah, a lot of research
- 47:20into looking at shark cartilage, looking at shark liver oil,
- 47:25looking at shark skin and the use of all of these products for
- 47:29improving human health, sometimes also design and
- 47:32engineering. So shark skin inspired a lot of
- 47:35innovations in modern sort of air, air flights and airspace.
- 47:40So my English has left me. I'm also being eaten alive by
- 47:43this land shark. Yeah.
- 47:48I mean, their evolutionary master sort of master creations.
- 47:52So it's no surprise that we're looking to learn from them about
- 47:55how we can heal and improve ourselves and be more resilient
- 47:58to to changes in human society and human health.
- 48:02Yeah, I mean for biomedical research, OK or whatever, you
- 48:04know, maybe one or two sharks, I can understand that.
- 48:07But you know, you don't need, you don't need to have a
- 48:09population level impact for, for that kind of scientific
- 48:12activity. So I I just can't see why that's
- 48:14allowed to continue. And for the commercial shark
- 48:17fisheries, I mean, they've just got, they've just got to stop.
- 48:20And yeah, I think producer Rob, can you not if you think we plan
- 48:23to campaign against shark fishing in Spain as well?
- 48:25There's a, there's a, yeah, it's a fairly fervent nod.
- 48:29So you consider that, consider that one of our future campaigns
- 48:32as well. Can people donate to Miyagu and
- 48:35help your work in the Maldives as well?
- 48:37I mean, we are a small volunteer on NGO, so we welcome any
- 48:41support. We do have a donation link on
- 48:43the page. We also welcome if you don't
- 48:45want to donate money, if you want to purchase equipment for
- 48:48us, we also welcome that. If anyone's listening that is in
- 48:51the biomedical field, you know, things like microscopes and lab
- 48:55equipment are all things that are really hard to come by here
- 48:57in the Maldives. And that make a big difference
- 48:59for our work, but also for our abilities to teach because the
- 49:02students don't always have access to some of these kits and
- 49:06resources. If people want to come diving
- 49:09with us and allow us to help them connect with sharks and
- 49:12change their minds and show them how incredible the animals are.
- 49:15And that's also something we always welcome either as
- 49:17research volunteers or just as dive guests.
- 49:21So I work very, very closely with a dive center called
- 49:23Oceanic Nomad Divers who in formula.
- 49:25So we do daily tiger shark dives and thresher sharks and other
- 49:29amazing species of sharks as well.
- 49:31So there's lots of ways to help and, yeah, highlighting the
- 49:36importance of sharks and supporting, you know, shark
- 49:39tourism, which keeps sharks alive, supporting that shark
- 49:43sanctuaries like the Maldives and Palau and other countries
- 49:45are being upheld. Those are a few big things we
- 49:49can do, or anyone can do. Well, we'll put a link to Miaga
- 49:52in the show notes and it's the this this threat to the gulpa
- 49:56shark about restarting the fishery, though that is that
- 49:58still a live issue. Can people sign a petition or
- 50:01somehow make their voices heard to the Maldivian government
- 50:04about that? Yeah.
- 50:06So there's a petition coming out in partnership with Blue Marine
- 50:09Foundation and Maldives Resilient Reefs on only one.
- 50:13So that will be shared very shortly on our socials as well
- 50:16that people can sign. And it's really a request to the
- 50:19government to not introduce Culper shark fishing or any
- 50:22shark fishing and to uphold the sanctuary here in the Maldives.
- 50:25And then there'll be a few more campaign videos and infographics
- 50:29coming out on Blue Moon Foundation Malnourished
- 50:32Resilient Reefs and Mirrors pages as well.
- 50:35OK. And what what's have you, have
- 50:37you been out already diving today?
- 50:39And are you you basically spent half the time in the water you
- 50:42have? This morning, of course, give
- 50:45us, give us. Just before we wind up, I want
- 50:47to know what your what your day was like.
- 50:49Get a sense of what it's like to live in one of these Maldivian
- 50:51islands. Yeah, start the morning with a
- 50:55cold coconut juice from my fridge, hop on my scooter, drive
- 50:59to the harbour along beautiful palm fringed roads, hopped on
- 51:03our Dhoni, which is a very traditional old Dhoni that was
- 51:06handmade by its previous owner, made from wood with beautiful
- 51:09carvings. We love her.
- 51:11She's old, but she's beautiful. And a Dhoni, for people who
- 51:14don't know, is a Maldivian traditional boat.
- 51:16Yeah, it's a Maldivian boat. And then we went diving first on
- 51:21the reef to look for thresher sharks, which are very beautiful
- 51:24and elusive shark species. Then we had our tiger shark
- 51:27dive. We only had 7 tiger sharks on
- 51:30today's dive, which for formula is a quiet day.
- 51:33We're much more used to having sort of 15 plus.
- 51:36And then we went into the blue with our guests to allow the
- 51:40sharks to come up under us and for them to see the sharks in
- 51:44deep water environment as well. And then I got back home, fed
- 51:48this little potato, the cat land shack, and now I have a few
- 51:54hours of data analysis ahead of me before giving a guest
- 51:57presentation about shark conservation, shark biology here
- 52:00in the Maldives, and then preparing the underwater cameras
- 52:05for tomorrow's surveys. Oh, wow.
- 52:09Gosh, that is a big piece of kit, Yeah.
- 52:12Big piece of kits. It's one of one of the few
- 52:14cameras that we have in the team.
- 52:17And then preparing for some of the next exciting research
- 52:19projects, pairing equipment, storing samples.
- 52:23We have a tiger shark poo sample in the freezer, which is a big
- 52:27success. It allows us to look into their
- 52:29diet. My dad laughs at me.
- 52:32He says, is this your life now you just collect shark poo.
- 52:34I say yes, I am living my dream. I get to collect shark poo.
- 52:41Yeah, I know. I agree.
- 52:42What's not to like? It sounds like you have a
- 52:44miserable you're certainly having a miserable time of it,
- 52:46so I can only commiserate with you.
- 52:49And if you want a nice holiday, come and visit us in in grey
- 52:52rainy Wales Happy. To Oh, but Wales has blue sharks
- 52:56in the summer. It has blue sharks.
- 52:59Yes, there's amazing opportunities to snorkel with
- 53:02blue sharks in Wales. I actually never heard of blue
- 53:05sharks so that shows how rignontal I am, but.
- 53:08I'll send your details. Yes, do do I just you, you
- 53:14haven't. You're doing an incredible,
- 53:15incredible work with me argue. And you know, I've been
- 53:17following your work with the multi social alliance for a few
- 53:19years and I can't recommend it too highly to to our audience.
- 53:23So Susan, just thanks again for for for sharing your time and
- 53:27your expertise and your experience with us.
- 53:29It's been it's been incredible. And we will put a link in the
- 53:31show notes to to me argue so people can visit and anyone
- 53:34who's yeah, anyone who's listening, don't worry about the
- 53:36carbon. Literally, you should go to
- 53:37visit, go to visit formula. It's spelled Fuva Mula for
- 53:42because it's it's pronounced a bit more shorthand, but yeah.
- 53:45And you will have the most most incredible, you know, shark
- 53:48diving experience of that it's possible to have, I think
- 53:50anywhere in the world. So, Suzu, thanks again.
- 53:53The best. Thank you so much.
- 53:55Thanks for having me and for your time and yeah, hope to see
- 53:57you soon. Thanks so much for listening to
