Latest / How To Protect The Ocean / Right whale baby boom: The fragile hope that could decide the future of a species
Transcript
- 0:00Alright folks, I have some fantastic news for you.
- 0:0321. That's right.
- 0:0421 North Atlantic right whale calves have been born so far in this season.
- 0:11This is the highest number for several years and we are seeing a huge turnaround
- 0:16or maybe potentially, possibly the beginning of a huge turnaround, but
- 0:20we're not anywhere close to increasing to the point where we need to.
- 0:23But this is actually a big turning point for a fragile species.
- 0:28But like I said, at the end of this, I'm gonna tell you why we're not out
- 0:30of the woods yet, but we're gonna talk about on today's episode of the
- 0:33How to Protect the Ocean Podcast.
- 0:34Let's start the show.
- 0:38Hey everybody.
- 0:38Welcome back to another exciting episode of the How to Protect the Ocean Podcast.
- 0:42I'm your host, Andrew Lewin, Marine biologist and science communicator
- 0:45here to tell you what's happening with the ocean, how you can speak up for
- 0:47the ocean, and what you can do to live for a better ocean by taking action.
- 0:52And I'll be honest guys.
- 0:53I'm not feeling the best today.
- 0:54I think I finally succumbed to a cold, maybe a little bit of a flu.
- 0:58I'm doing this because not only is it great news, but we need to put an
- 1:01episode out and I don't want you to go a day of the three days of the
- 1:04week that I post without an episode.
- 1:06So I'm putting this episode out, so excuse if my voice starts to go.
- 1:10But I was at a hockey tournament this past weekend.
- 1:12My voice started to go, then I started to get sick.
- 1:14So I apologize, but this is great news.
- 1:17The North Atlantic white whale, a critically endangered species,
- 1:20has had 21 calves so far.
- 1:23Now for a species with only about 360 individuals remaining,
- 1:27every calf that's born matters.
- 1:30So the question remains, is this a turning point or is this a fragile moment of hope?
- 1:34This is a very interesting and positive outlook on what we're seeing
- 1:39for a critically endangered species.
- 1:41It's a species where the number of calves actually outweigh sort
- 1:46of the population replacement.
- 1:47Every year, if you think about it, there are a number of calves that
- 1:50will pass away just because of old age or something that happened.
- 1:53So with North Atlantic, right whales, you end up seeing, you know,
- 1:56just from old age, they pass away.
- 1:57You see it from entanglement in fishing gear.
- 2:00They pass away or ship strikes they pass away, which are the two that we're trying
- 2:03to control the most to make sure that they don't pass away from those things.
- 2:07But 21 calves actually helps replace more than any of the lost
- 2:11animals that we saw, or individuals that we saw in the previous year.
- 2:14So this is great to see that.
- 2:16Now the calving season runs roughly November through April.
- 2:19This is only the beginning of February.
- 2:21There's still time to get more calves or be able to discover
- 2:24more calves that are being born.
- 2:25Recent years saw fewer than 10 calves that were born and some
- 2:28years as low as zero calves born.
- 2:31So each calf represents a measurable population boost,
- 2:34not just a symbol of hope.
- 2:36Every year, you're probably wondering how these animals get discovered.
- 2:40It's very difficult.
- 2:41You don't actually see the births a lot of the times.
- 2:43You're very lucky if you are even to see it.
- 2:45I don't even know, to be honest, if a North Atlantic right whale
- 2:47birth has been witnessed in person.
- 2:50It's a very difficult thing to see 'cause they might do it underwater.
- 2:53They'll probably go down below over the surface.
- 2:54They may not do it at the surface, but eventually they wanna do it
- 2:57close 'cause they want to get that calf up to the surface and help
- 3:00it breathe for the first time.
- 3:01It's very difficult to see.
- 3:02But when you see the calfs born is usually when you start to see them
- 3:06as they migrate north or even south.
- 3:09In this case, because it's winters, they're probably migrating a little
- 3:11bit south and you start to see them in their calving area, usually
- 3:14around Jacksonville, Florida.
- 3:16And so you'll see aerial surveys off the southeastern United
- 3:20States, photo identification of mother and calves, long-term
- 3:23individual whale tracking will happen.
- 3:25And this is kind of interesting because the population is so low,
- 3:28360 individuals in and around there.
- 3:30We tend to know each and every whale.
- 3:32You can identify them by scars or any kind of unique formations on their body.
- 3:37When you have a population of individuals that's critically endangered, you only
- 3:41have about 360 in and around individuals.
- 3:44You tend to know each and every individual.
- 3:46There have been aerial surveys.
- 3:48There've been photo identifications, long-term individual whale tracking
- 3:51because they're able to identify unique markings, whether they're
- 3:56scars of anything, whether it be from entanglement or just maybe it
- 3:59be from just living in the ocean.
- 4:01It can be rough in the ocean.
- 4:02You be able to identify them.
- 4:04People who are taking photographs from aerial photos, people who are taking
- 4:07photographs from boats, from land.
- 4:09And so what you're able to identify them area, they'll piece it all together.
- 4:12And when you do these types of aerial surveys or from boats or even from land,
- 4:17you're able to see individuals pop up and new individuals pop up.
- 4:20These little calves that are small-ish compared to the rest of the North
- 4:24Atlantic right whale, the adults.
- 4:25And so you're able to see the mothers kind of look after those calves.
- 4:28When you see one pop up, you're like, oh, this is new.
- 4:31We haven't seen this calf before, because there's a database.
- 4:33And so when you put those pictures in the database, they just rifle through.
- 4:36Identify and line up the unique markings.
- 4:39There's programs that look up and predict which of these animals they are.
- 4:42They attach 'em to either a number or a name or both, and they're able to say,
- 4:46Hey, this individual's here and this mother is now a mother for the first time
- 4:50or the third time or the fourth time, and they're able to go back and forth
- 4:53and look at that, which is pretty cool.
- 4:54So the interesting part about all of this is that more calves
- 4:58are being born obviously.
- 5:00But that means the mothers are probably healthier than before.
- 5:04Even the fathers to be able to create these beautiful calves, they
- 5:09have to be in a particular manner where they have to be healthy.
- 5:12They have to be well fed.
- 5:13They can't be tired from swimming all this time.
- 5:16They have to be in a pretty good body condition to feel like reproducing.
- 5:20And the fact that they're doing this indicates that there's some potential
- 5:23short-term success of protections, like these protections are working.
- 5:27So the fact that there are slowing down vessels in and around
- 5:29certain areas like the Gulf of St.
- 5:31Lawrence up in Canada and even down south in the US where there
- 5:34are natural ranges and now they're going into the Gulf of St. Lawrence.
- 5:37With climate change, it's getting warmer so they can go more
- 5:39north than they normally do.
- 5:40And so you're seeing, you know, changes during seasons when they're around
- 5:45and you're starting to see some success in that where these animals
- 5:48are not damaged, they're not hurt.
- 5:50They're able to actually be healthy enough to reproduce.
- 5:53So you're starting to see more and more.
- 5:54A couple years ago, like even last year and the year before, the year
- 5:57before that, we started to see some increases in calves, but we were still
- 6:01fairly cautiously optimistic about it.
- 6:03And same with this.
- 6:04We saw a big rise in the number this year.
- 6:06Still cautiously optimistic 'cause we just don't know if this is just a one-off
- 6:11or if this is the start of potentially a new thing where we're starting
- 6:14to see the recovery of this animal.
- 6:16So this is hope, but it's not recovery.
- 6:20I'm gonna say it again.
- 6:21This is hopeful but it's not signs of recovery just yet.
- 6:25If we start to see a number of years put together, 2, 3, 4, 5, then we're
- 6:30gonna start to say, Hey, you know what?
- 6:32We have some recovery happening.
- 6:33And now that'll be really great news.
- 6:35I hope we get to that point.
- 6:36I just don't know if it's gonna happen.
- 6:38We still have some major threats.
- 6:41I wanna bring back the reality of the situation.
- 6:43There are ship strikes where these animals, as they migrate and feed
- 6:47in busy shipping lanes, there's certain times of the year where these
- 6:50animals are in these shipping lanes.
- 6:52And they could be busy times, you know, for those transport ships, right?
- 6:55As they go across, these animals tend not to get outta the way very quickly, and
- 7:00they're very hard to see because they'll stay just below the surface of the ocean.
- 7:04And they'll just kind of hover there.
- 7:05They don't come up often for air and they're just kind of coming and they
- 7:08staying just below the surface where they're more vulnerable to getting hit.
- 7:12So ship strikes and collisions are often a result in fatal injuries.
- 7:16And so to see less of those is great,
- 7:19like just showing by the fact that we have a healthier adult.
- 7:22But it doesn't mean it's gonna stop.
- 7:23That's a big problem.
- 7:24And of course we have fishing gear entanglement.
- 7:26So fishing gear entanglement happens when you have these lobster pots or crab pots.
- 7:30They're down at the bottom of the ocean, but there's a line that
- 7:33goes up to buoys that are at the surface so that the fishermen can
- 7:36come back and grab those buoys.
- 7:38So those fishers will come back.
- 7:39They'll use those buoys, they'll grab it, they'll pull up the crab pots or
- 7:42lobster pots, and then they'll take whatever they caught outta there.
- 7:45Unfortunately, when those lines are going through, these whales can't really
- 7:48see the lines, you know, the actual fishing lines or the lines that prop
- 7:52up the buoys and keep the buoys up straight, or keep the buoys attached
- 7:55to the crab pots or the lobster pots.
- 7:57The whales will actually swim through and they'll get caught.
- 7:59They'll get caught between theyre flipper and like just inside their pectoral fin.
- 8:04And so they'll get it caught there and it'll just keep going.
- 8:05And what happens is that line will actually cut through.
- 8:08As they're moving through the water,
- 8:10it's causing friction and it's causing like the buoy and the crab put on
- 8:13the each side to be dragged around.
- 8:15That line will kind of sever into the pectoral fin causing infection
- 8:20and it's hard to recover when you can't get it cleaned, you
- 8:23can't bandage it up, obviously.
- 8:25And so animals can die from those types of wounds.
- 8:28So we see this happen all the time.
- 8:29In fact, unfortunately a 4-year-old whale passed away.
- 8:32It was, you know, very hopeful that it was gonna do well.
- 8:35But it wasn't the first time that it had been entangled.
- 8:38I think it was like the third or fourth time that had been
- 8:40entangled in his four year life.
- 8:42Because it died of that, we're still seeing problems with entanglement, and
- 8:46we're gonna see problems with entanglement until we get rid of these types of fishing
- 8:50pots where they need a line and a buoy.
- 8:52We're working on solutions for that.
- 8:54There's a lot of fisheries that are going through experimental
- 8:56fisheries where there's no line.
- 8:58It's just like you press a button and these balloons pop up and the crab pots
- 9:02or lobster pots will just float to the top and they have to go and retrieve them.
- 9:05They're not perfect technology yet, but they're working better
- 9:07than originally expected.
- 9:09It's better than it was and it's gonna be better in the future,
- 9:12but we're still seeing loss of animals life because of this.
- 9:16The human cause there response to is still the vast majority
- 9:19of the known right whale deaths.
- 9:20Not just natural causes or beaching 'cause of a mystery.
- 9:23It's usually just because of these two things, ship strikes
- 9:26and fishing gear entanglement.
- 9:28So the fact that we're seeing solutions in slowing down ships so that it gives
- 9:33a chance of the whales to move or it gives a chance for the ships to react
- 9:36if they do see this whale, even though it's difficult to see that is helping.
- 9:40If they slow down from 20 knots to 10 knots, that's shown to
- 9:43help, which is really great.
- 9:44Also, like I said, the ropeless fishing gear really helps.
- 9:47We've seen increased cooperation between Canada and US agencies.
- 9:50I know that's difficult to think about at this point, but we're also
- 9:53seeing that, which is really great.
- 9:55And then we're also seeing real time whale alert systems for
- 9:57mariners happen at buoy systems.
- 9:59So we know when these whales are in the area, they're able to alert different
- 10:03ships that there's whales in the area.
- 10:04They can slow down.
- 10:05And so that's great.
- 10:06So adoption is growing but it's not universal and it's not fast enough.
- 10:11So what you need quicker experiments happening, more starting to use ropeless
- 10:16gear, starting to slow down ships like voluntarily from transport
- 10:19ships, not just making them do it.
- 10:22And then of course enforcement is gonna be huge when it comes to that.
- 10:24So there's been a lot of progress in that.
- 10:27And look, fishermen and fishing communities are working with scientists
- 10:32to help, which is great to see.
- 10:34And you see some shipping industry working as well 'cause
- 10:36they don't want to hurt a whale.
- 10:37They don't want run into a whale.
- 10:38It doesn't look good for them.
- 10:39It's not good for their captains, but it's also, you know, something that
- 10:42they don't wanna have to go through.
- 10:43So I think it's really great.
- 10:45So the, the big thing is 21 calves is real progress.
- 10:48It's really great to see.
- 10:49Species are still critically endangered.
- 10:51They're still dying in recovery will depend on what humans do next.
- 10:54How are we going to make things better through innovation like ropeless gear
- 10:58through slowing down ships to reduce any incidences or chances of ship strikes.
- 11:04And then just more technology for alert systems and being able to detect whales
- 11:08when they're in and around a specific area is gonna be really, really great.
- 11:12I think it'll be a good future for them.
- 11:14I think we're gonna be able to save them.
- 11:15There's still enough individuals, even though they're critically
- 11:17in danger, there's not a ton of reproductive females left.
- 11:20I think there's less than a hundred.
- 11:22If we can see an increase and we can see these calves get to
- 11:24adulthood, that's even better.
- 11:26And more and more calves every year is great.
- 11:28I'm hopeful, but like I said, it's not recovery.
- 11:30We can still have hope, but it's not recovery.
- 11:32We still need to do more.
- 11:33And we still need to like have you guys not only learn about this, but make
- 11:37sure that your government officials are making sure these policies are being
- 11:40stood right up to it and people are abiding by it and we're enforcing it.
- 11:44' cause that's a huge thing to do.
- 11:45So it depends on not only us, but our governments.
- 11:48Our fishing communities, our shipping communities.
- 11:51This is all happens to work well in our favor.
- 11:54So hopefully we can see the recovery of these species soon, and we're
- 11:56hopeful right now, and hopefully later we'll see the recovery.
