Latest / How To Protect The Ocean / Whose Dinner Becomes Fish Feed?
Transcript
- 0:00On a May morning in 2017, the people of Gunjur in The Gambia woke up to find
- 0:04their lagoon had turned red overnight.
- 0:07Imagine that, dead fish floating on the surface.
- 0:10Investigators traced it to a fish meal plant up the road.
- 0:13And today we're gonna be talking about whose dinner becomes fish feed,
- 0:15and what a village can do about it.
- 0:18We're gonna talk about that on today's episode of the How
- 0:20to Protect the Ocean podcast.
- 0:21I am your host, Andrew Lewin.
- 0:22I'm a marine biologist and science communicator here to give you what's
- 0:25happening in the ocean, from ocean news, to ocean science, to ocean conservation.
- 0:30And this week we are discussing what farmed fish eat, and fish meal, and fish
- 0:34feed, whatever you would like to call it.
- 0:36Yesterday we talked a lot about, what farmed fish eat
- 0:39and how they eat wild fish.
- 0:41The day before we talked to, Maya, who is from the Outlaw Ocean Project, and
- 0:46she talked all about their five-year investigation of fish meal, which spawned
- 0:50or inspired me to do this, to do these solo episodes this week, to really
- 0:55bring home and dive into a lot of the different aspects that they dove into.
- 0:58I'm gonna link to their website so that you can dive more into it
- 1:02if you wanna get more information.
- 1:03Very, very interesting study or investigative reporting,
- 1:07I should say, for five years.
- 1:08We don't see that a lot and it was really happy that they chose me to
- 1:11tell, their story, or one of the people to tell their story, or have them
- 1:15on the platform to tell their story.
- 1:16So it's really great to be able to be a part of that and for people to
- 1:19come in and start to ask questions and really give us information for us.
- 1:23' I didn't have this information.
- 1:24Nobody really had this information, so we're gonna dive into it.
- 1:27'Cause the thing is, is like when we talk about eating seafood,
- 1:30we wanna do the right thing.
- 1:31and it's really difficult sometimes to do the right thing.
- 1:33We've talked about it on the podcast before with all the different apps that
- 1:36are doing, like there are people who are out there who are just scrounging for data
- 1:39on sustainable fishing or on the fisheries that are happening around the world.
- 1:42And they make decisions based on their criteria, which is fully transparent,
- 1:46to say, "Hey, how is this in terms of sustainability?" So that we can have a
- 1:50simple app to say, "Yeah, avoid this fish from this place and how it's caught, and
- 1:54go with this fish as an alternative," or seafood or whatever it is.
- 1:57Doesn't always have to be fish.
- 1:58As in yesterday's episode, I said, "Hey, eat more like farmed bivalves," 'cause
- 2:02we know they don't ea-eat fish meal, and we know you can control that more.
- 2:05So if you wanna have like that knowledge that, yes, you wanna eat seafood, but you
- 2:09wanna eat the right way, you know bivalves are good because they're filter feeders.
- 2:12They don't eat fish meal, It's not to say that the others are wrong, it's just
- 2:16we just don't have a lot of information on it right now, as much as we need to.
- 2:19It'll be interesting to see how a lot of these apps, like these certification apps,
- 2:24will deal with everything that goes on.
- 2:27You know what I mean?
- 2:27Like all this new information and stuff that nobody knew about, you can only
- 2:31know by boarding the boats or talking to some of the fishers and stuff like that.
- 2:35the people who are involved in doing the certification don't always have access to
- 2:40everything in, I guess the food chain in terms of, the supply chains, I should say.
- 2:45And so that, becomes difficult, and they know that.
- 2:47Like, it's not something that they don't say.
- 2:49They're scientists.
- 2:49This is what they do, and they work hard at what they do, and
- 2:51they give us a service that's really, really important for free.
- 2:55And, like for us for free anyway, we don't really have to pay for it.
- 2:58So, I guess, like, the thing right now is, like, as you go into these episodes
- 3:00that we're talking about, is really understand that nothing is perfect, and
- 3:05we wanna try and get to perfect, and we're always striving for perfection,
- 3:08but we're not always gonna be there.
- 3:10And the fact that The Outlaw Ocean Project came up with this study and was able to
- 3:15reveal what it was able to reveal will help change the future of the system.
- 3:20That's how it works, that's really how it works.
- 3:21So, really happy that they were able to tell us all about it and
- 3:24we're able to do these episodes.
- 3:26So, this is, really the key with farm fish and what they eat.
- 3:30feed is the link, so we're gonna follow that, it's easy to feel that a problem in
- 3:35West Africa has nothing to do with salmon filet in Toronto, London, or Sydney,
- 3:40but that link of that fish meal really does help, and so we're gonna follow
- 3:43it today to kinda give you that guide, I spent years talking about upwelling
- 3:48on the coast, Peru and West Africa, where cold water rises and feeds both,
- 3:52like, wildlife and human communities that are local or even international.
- 3:56We know now that everything's global.
- 3:58And that's who this story is about, Is to make sure that we are understanding
- 4:02what is happening here, And so In Senegal and The Gambia, which is West
- 4:07Africa, small fish like sardinellas and bonga are everyday protein.
- 4:12That's what they eat.
- 4:13And in The Gambia, more than 80% of the people rely on
- 4:17these small fish like bonga.
- 4:19In Senegal, fish supplies nearly half of all the protein.
- 4:23Some of the industry, of fish meal or any kind of other industry, they
- 4:26call these types of fish, these small oily types of fish, trash
- 4:29fish, as if nobody would miss them.
- 4:31it's really interesting because people do miss them when they're gone, when
- 4:35they're not given to them, or they're taken away somewhere else, or the supply,
- 4:39the wildlife supply is overfished.
- 4:42And I think this is where marketing comes in and, the ability to manipulate
- 4:47thoughts based on how they call a fish.
- 4:49I'm gonna just go into a little tangent here.
- 4:51In Antarctica, there is a fish called, the, Patagonia sea bass, and it's off the
- 4:57coast of Chile, but it's in Antarctica.
- 4:59And this fish is kind of interesting.
- 5:02I'm gonna have to look it up as I record this because I think it's something that's
- 5:05really interesting the Patagonian sea bass is actually the Patagonian toothfish.
- 5:10and the reason why they call it sea bass, 'cause everybody loves sea bass.
- 5:13When you think of a sea bass, you think of this, like, slender, good-looking fish.
- 5:17it's almost like the influencers of what a supermodel or, I don't know what
- 5:22the equivalent for male models, but a model would be compared to, like, your
- 5:25average day person, Everybody's like, "Oh, yeah, this person looks like a
- 5:28supermodel." they're not gonna say, "This person looks like the everyday person."
- 5:32And so Patagonia toothfish are not by our, society's standards, a good-looking fish.
- 5:38They look a little scary.
- 5:39They're very toothy, hence the toothfish.
- 5:41But when you call it sea bass, it's something different.
- 5:44it's attractive.
- 5:44It's something that you would like to see in a supermarket or a fish market on
- 5:48the ice, and you see the full fish, and you're like, "Oh, that's a beautiful fish.
- 5:51I would like to eat that fish." You see a Patagonia toothfish,
- 5:54actually what it looks like and not just the filet, and you're like,
- 5:56"Oh, yeah, no, that looks scary.
- 5:58I'm not sure if I wanna eat that." it's just based off looks.
- 6:00So marketing matters in this situation, which can be a little difficult.
- 6:04So I wanna talk a little bit about how people rely on this episode
- 6:09because I think it's important to make that connection in how
- 6:11people use these type of fish.
- 6:13Fatu Samba is a fish processor in Bargny, a coastal town outside of Dakar, Senegal.
- 6:19Now for years, women like her bought fish on the beach, then smoked it
- 6:24and dried it and sold it, and that's how sardinella reached family tables
- 6:27across the region, same process.
- 6:30Probably not the same, like, not by Fatu, but by the same process.
- 6:33Now, in 2023, at 58 years old, she told reporters from The Outlaw Ocean
- 6:38Project what had changed, and she says, "Today, having three daily
- 6:42meals has become a problem," which has never happened to them before.
- 6:45She said, "We don't think about saving money.
- 6:47We think about our survival." In Senegal, prices for fresh and dried fish more
- 6:52than doubled between 2019 and 2025, and the number of women processing fish
- 6:56dropped from more than 300 to about 70 So, like, before these plants arrived,
- 7:02a full market was a natural break.
- 7:04If nobody could buy more fish, fishers stopped bringing it in, Fish meal
- 7:08plants buy, like, unlimited volumes.
- 7:10They just buy as much as they can.
- 7:12And now there's a buyer for every last fish, and the plants
- 7:16outbid the women processors.
- 7:18So instead of having individuals on the beach who are essentially
- 7:21entrepreneurs supply these fish, they just go to the processing plants.
- 7:26And fishers will go right to the processing plants 'cause they
- 7:28might get a better price for them.
- 7:30So both species of sardinella in the region are now at risk
- 7:33of collapse because of all this.
- 7:34There's no such thing as unlimited fish.
- 7:37And according to a 2024 study in fishery science, this is what happened,
- 7:40they're just at risk of collapse.
- 7:42' when you have plants who are shipping internationally and you
- 7:46have fishers who are bringing it… So these are local fishers who
- 7:48are making money from the plants.
- 7:50The plants, hire other people, they buy all the fish up, and
- 7:54they send it internationally.
- 7:56It takes away from the local economy.
- 7:58Maybe not from the local fishers, but it takes away from the local economy.
- 8:01And because they're supplying a global market, they're gonna
- 8:03take as many fish as they can.
- 8:05They don't necessarily care about the local fish stocks.
- 8:08They are just there to make a buck.
- 8:11That's what they're there.
- 8:11They're making their profit.
- 8:12And when the fish is gone, they will leave the plants and they will just leave.
- 8:16That's business for a lot of people.
- 8:18Now, another story here is on October 22nd, 2022, a tanker called the Kibe
- 8:23pulled up into a place called Nouadhibou.
- 8:26I'm not sure if I'm pronouncing that properly, but it's a fishing hub of
- 8:29Mauritania, just north of Senegal, and it loaded tens of thousands of tons,
- 8:34tens of thousands of tons, I want to repeat that just to make sure we
- 8:38got it, of fish oil that comes from the sardinella and, from the bonga.
- 8:42So then ship sailed more than 3,000 miles north to Norway, and the oil was
- 8:47headed for a company called Mowi, which is the world's biggest salmon farmer.
- 8:51And that's the company that I mentioned in yesterday's, opinion, where there
- 8:54was that one person who said, "Hey, we just can't keep doing this anymore."
- 8:57Now, a documentary crew traced that voyage of the 3,000 miles north,
- 9:01And about a year later, the Financial Times followed that same ship.
- 9:04Both linked the trade to rising sardinella prices, which were leaving local families
- 9:08unable to afford a traditional staple.
- 9:11Let's just think about that.
- 9:13are supplying fish and fish oil and fish meal for farmed salmon that will
- 9:18tend to go towards Western companies or developed countries, let's just
- 9:22say, countries that could afford the fish and that will eat salmon, farmed
- 9:25salmon, which is a lot of people.
- 9:27the fish that are feeding those fish, you're taking it away from the
- 9:30local community who are eating it.
- 9:31Suppliers will call it trash fish, so they're like, "Nobody's eating
- 9:33this stuff." But nobody bothered to speak up and cared for it.
- 9:37I'm sure people have.
- 9:38I don't wanna say nobody, but like, the people who are shipping this
- 9:41out, they just don't really care.
- 9:43And obviously that's a problem, Now, a 2026 study in PNAS, a scientific
- 9:47journal, found that most of the fish meal traded internationally comes from
- 9:51countries where many people already struggle to get enough nutrition,
- 9:55Now keeping that catch at home could meet the nutrient needs
- 9:57for up to 31 million people.
- 10:00Now think about that.
- 10:01That ship, Key Bay, just took away food for 31 million people.
- 10:05So I want you to hold onto that and we'll come back at the end.
- 10:08Now more than 9.5 million people worldwide live within a mile of a
- 10:11fish plant, and the smell comes mainly from a gas called Trimethylamine.
- 10:16at industrial levels, it can cause headaches, nausea, and irritation,
- 10:21and researchers also warn it can turn to nitrosamines, and that's
- 10:25a group of compounds that include probable human carcinogens.
- 10:28Now some plants have dumped wastewater into lagoons and onto beaches.
- 10:31This is where people are actively like they just end up being, and
- 10:35that's what turned Gunja's lagoon red.
- 10:38It's the fact that all this wastewater from these fish plants that are processing
- 10:42the fish oil, that are taking those fish away from the plants and away
- 10:45from that country of the people who depend on as food sources and that are
- 10:49struggling to meet their nutritional needs for three meals a day, then what
- 10:53they do is they take all the waste and that wastewater, and they dump it onto
- 10:56beaches and into the local lagoon.
- 10:58This is an assumption, without the proper levels of filtration
- 11:02to properly treat that wastewater.
- 11:04I'm in Canada, if you're in the US, you have treatment plants that will
- 11:08treat that as much as possible and that will make it into as clean of
- 11:12wastewater as you can to dump it back in.
- 11:14It's not perfect, but it is much better than a lot of places.
- 11:16I assume in The Gambia, in Senegal, this isn't happening.
- 11:21This next story that I'm gonna talk about, I wanna just say that
- 11:23it involves people dying at sea.
- 11:25So it's a bit of a trigger warning here.
- 11:26Obviously I don't like talking about, but we have to talk about something like
- 11:29this, so when fish disappear and the jobs go with them, some people leave.
- 11:34They have to leave.
- 11:35They have to go find work.
- 11:36And researchers name collapsing fish stocks as one of the, factors
- 11:39amongst several, alongside climate change and economic hardship.
- 11:43So researchers name collapsing fish stocks as one of the factors
- 11:46like, among the several that are.
- 11:48Like, along with climate change and economic, hardships.
- 11:51Now, this next story we're gonna talk about, again, here, this is where
- 11:54we're talking about some death at sea.
- 11:55Pape Demba Sy was a skilled fisher in Senegal, and he used, to bring sardinella
- 12:00to the women processors on the beach.
- 12:03And more often, he came home from day-long trips with empty nets
- 12:07because the fishers is overfished.
- 12:08And in 2006, he tried for the first time to cross the Atlantic by boat to
- 12:12Spain's Canary Islands, which is a set of islands just off of the coast of Africa.
- 12:16And he carried 50 euros and a photograph of his parents.
- 12:19He wanted to support his sick mother.
- 12:21Now he didn't make it.
- 12:22He was intercepted, or he was detained in Morocco or forced
- 12:25back when engines failed.
- 12:26So he tried again and again,
- 12:28By 2011 he made nine attempts.
- 12:31And people started to call him Nine Times because that's what he was known for.
- 12:34And he told reporters he just, he'd keep trying.
- 12:37I am the hope of my family," he said.
- 12:39Now in 2025, about 1,900 people died on the Atlantic route to the Canary
- 12:44Islands, according to the fisheries rights group, Caminando Fronteres.
- 12:471,900 people died trying to cross that area Now in 2018,
- 12:52a fish meal plant opened up.
- 12:54. So the fact is that we're seeing poorer areas because they don't
- 12:56have access to food, they don't have the nutrition, they need help.
- 12:59They need medical help.
- 13:01They need nutrition.
- 13:02People are trying to leave to get a better life, to bring money
- 13:06back home to support their family because there's nothing else left.
- 13:09And then you have these plants that are local within Senegal, within The Gambia,
- 13:14and they are putting out wastewater onto the beaches and local lagoons that
- 13:19are effectively turning the, water red.
- 13:21And people are swimming in these areas, and they're, obviously,
- 13:24like imagine Florida or even Lake Ontario having that kind of stuff.
- 13:28We wouldn't be standing for it.
- 13:30That'd be an emergency, a state of emergency.
- 13:32So you're having all these problems.
- 13:34I wanna take you back to the fish meal plant because how
- 13:37do people deal with this?
- 13:38And in 2018, a fish meal plant opened in Abene, which is a
- 13:41small town in southern Senegal.
- 13:43Almost immediately, residents noticed that heavy stench and a thick black
- 13:47smoke, and untreated wastewater ran into the rice fields and garden wells.
- 13:51Within weeks, dead fish washed up on the beach.
- 13:54Was already starting to see this happen right as the fish plant
- 13:57starts to get started and built.
- 13:58Now the town organized.
- 13:59They said, " we're not gonna take this anymore." Youth groups and local
- 14:02activists ran protests and petitions, and they held outdoor screenings of a
- 14:06documentary about the fish meal industry.
- 14:09And so they're, educating themselves.
- 14:10They're spreading the word.
- 14:11The environment ministry oversaw the community vote, and more than
- 14:1490% of the people opposed the plant.
- 14:17Six neighboring villages signed a joint statement, and in July
- 14:202018, which is, a few months later, three months after it opened, the
- 14:25government suspended the plant.
- 14:26Now, Abene had no special powers, This town.
- 14:29It used every tool that it had, and that worked.
- 14:32That worked for them in this situation.
- 14:34Kayar, also in Senegal, banned wastewater discharges in January
- 14:382023, and the technology to control the stench actually exists.
- 14:42Like, people can get a hold of this.
- 14:44A Peruvian scientist built a trimethylamine monitor
- 14:48for a few hundred dollars.
- 14:49Now, the two biggest names in salmon feed, Skretting and Mowi, say they've avoided
- 14:53fish meal and fish oil from West Africa since 2023 because of these problems.
- 14:58Which is a year after that tanker sale, the Key Bay, that
- 15:00we discussed in this story.
- 15:02So when we start looking at everything that's happening, West Africa, the local
- 15:06people had depended on wild fish stocks, small wild fish stocks, sardinella, bonga.
- 15:12like, they were staples in their meals, probably three meals a day oftentimes.
- 15:17start to get in these fish meal plants that are taking those fish, grinding
- 15:21them down to fish feed and fish oil, like into a powder and oil, and then
- 15:25sending them elsewhere, up to Norway and other places to provide fish
- 15:29feed for salmon farms, and I'm sure other farms as well around the world.
- 15:33Then people start to realize, " This isn't working for us." The stench, the
- 15:37wastewater that we see, or the fact that we don't have fish to feed on.
- 15:40We have to leave.
- 15:42We have to try and come back.
- 15:42People die going across the Atlantic.
- 15:44It's not an easy thing, and I'm not sure if you've ever seen the videos
- 15:46of people who are trying to get to the Canary Islands to Spain, but it's
- 15:50treacherous, and they're in small boats, and there are a lot of people in
- 15:52these boats, and a lot of people die.
- 15:54As I mentioned, 1,900 in that one year.
- 15:56it's not for the faint of heart.
- 15:57and they're just doing it to survive.
- 15:58They're trying to get better work so they can send the money back to their families,
- 16:02and it's at no fault of their own.
- 16:04They're just in it because they have to be in it.
- 16:08And so what I want you to get out of this is that they found the problem.
- 16:12certain cities and certain villages stopped the fish plants
- 16:16from working the way they do.
- 16:17There's still a lot of work that needs to be done.
- 16:19it's not over.
- 16:20These are just small local stories, but these fish plants are all over,
- 16:24and as the Outlaw Ocean Project identified, there are a lot of problems.
- 16:27Sometimes these protests are not civil.
- 16:29There's a lot of civil unrest, and so it can get violent in certain situations.
- 16:33People can get hurt, but they're standing up for what they believe for their
- 16:36own survival, for their own nutrition, just to have three meals a day.
- 16:40I think that's important to realize when we look at the way we have farmed fish.
- 16:46And this is not to say that the entire industry is awful.
- 16:48It needs to be cleaned up.
- 16:50There's no doubt about that, and we are always trying to work, because
- 16:52business people will be business people, and they are going to try
- 16:55and make as much money as possible.
- 16:57Some of them care, some of them don't, and, the ones that don't are
- 17:01the problem that we need to fix, and we need to put those regulations
- 17:03in, and we need to support these.
- 17:05So I guess what I'm saying is that we should be looking at
- 17:08it from a holistic perspective.
- 17:11your farmed salmon that you're eating on your plate at night, it's one meal to you
- 17:16But as that's happening, people are losing meals in Africa because of the fish feed
- 17:21that goes into fish to feed that salmon.
- 17:24So I want you to think about that.
- 17:25Don't feel guilty.
- 17:27let's stand up to the people who are doing this.
- 17:29And the one thing you can do is just send an email.
- 17:32Imagine that.
- 17:33Send an email to the brand of the farmed salmon or shrimp you buy Like, if you
- 17:37have a specific company that you like 'cause you like that company or that,
- 17:40Costco or somewhere else, provides, send an email to Costco, send an email
- 17:44to the Marine Stewardship Council, send an email to Seafood Watch, say, "Hey,
- 17:48are you taking this into play when you do your, apps, your certification?
- 17:51'Cause this is really important." And don't treat them as the enemy, treat them
- 17:54as an ally to be like, "Hey, I just want to know, do you guys know about this?
- 17:57How are you incorporating them?" But also the brands that you're buying from.
- 18:00like, tell us your process.
- 18:01like, are you using fish meal from Africa?
- 18:03If you're not, that's great.
- 18:04Let us know.
- 18:05We wanna know.
- 18:06We're gonna continue to find out, but send that email.
- 18:08It's one email that you have to send.
- 18:09It's not very difficult.
- 18:10You can do that in two minutes, and that, one question, does your feed contain
- 18:14fish meal or fish oil from West Africa?
- 18:16Just from that one thing to do based off of this episode.
- 18:19If you can do that, that would be amazing.
- 18:22Because, the thing is, is, like, the village voted the plant that was
- 18:25polluting their area after three months.
- 18:26Like, they were able to do that.
- 18:28And then the tanker route that made the headlines is one of the
- 18:30companies that said they've closed that, they've shut that route down
- 18:33because of what was happening.
- 18:35the good news is the changes have been made.
- 18:37The bad news is there still need to be more changes, and
- 18:40so you can help by doing that.
- 18:42And when people at both ends of the supply chain speak up, like, one
- 18:45of the family members at Maui said, "Hey, we're not gonna do this anymore.
- 18:48We need to look at this fish meal," that's when fish start staying home,
- 18:51and that's when people can survive at home, and that's when people,
- 18:54like the fishery stocks remain, and it helps the environment as well.
- 18:58So people in the environment, when we're trying to do conservation,
- 19:00it's all about managing people, and this is the way we manage people.
- 19:03And I wanna thank you so much.
