Will the ocean ever run out of fish? – Ayana Elizabeth Johnson and Jennifer Jacquet


Fish are in trouble. The cod population off Canada’s East Coast
collapsed in the 1990s, intense recreational
and commercial fishing has decimated goliath grouper populations
in South Florida, and most populations of tuna
have plummeted by over 50%, with the Southern Atlantic bluefin
on the verge of extinction. Those are just a couple of many examples. Overfishing is happening
all over the world. How did this happen? When some people think of fishing, they imagine relaxing in a boat
and patiently reeling in the day’s catch. But modern industrial fishing,
the kind that stocks our grocery shelves, looks more like warfare. In fact, the technologies they employ
were developed for war. Radar, sonar, helicopters, and spotter planes are all used to guide factory ships
towards dwindling schools of fish. Long lines with hundreds
of hooks or huge nets round up massive amounts of fish,
along with other species, like seabirds, turtles, and dolphins. And fish are hauled up onto giant boats, complete with onboard flash freezing
and processing facilities. All of these technologies have enabled
us to catch fish at greater depths and farther out at sea than ever before. And as the distance and depth
of fishing have expanded, so has the variety of species we target. For example, the Patagonian toothfish
neither sounds nor looks very appetizing. And fishermen ignored it until
the late 1970s. Then it was rebranded and marketed
to chefs in the U.S. as Chilean sea bass, despite the animal actually
being a type of cod. Soon it was popping up in markets
all over the world and is now a delicacy. Unfortunately, these deep water fish
don’t reproduce until they’re at least ten years old, making them extremely vulnerable
to overfishing when the young are caught before they’ve
had the chance to spawn. Consumer taste and prices can
also have harmful effects. For example, shark fin soup is considered
such a delicacy in China and Vietnam that the fin has become
the most profitable part of the shark. This leads many fishermen to fill
their boats with fins leaving millions of dead sharks behind. The problems aren’t unique
to toothfish and sharks. Almost 31% of the world’s fish populations
are overfished, and another 58% are fished
at the maximum sustainable level. Wild fish simply can’t reproduce
as fast as 7 billion people can eat them. Fishing also has impacts
on broader ecosystems. Wild shrimp are typically caught by
dragging nets the size of a football field along the ocean bottom, disrupting or destroying
seafloor habitats. The catch is often as little as 5% shrimp. The rest is by-catch, unwanted
animals that are thrown back dead. And coastal shrimp farming isn’t
much better. Mangroves are bulldozed to make room
for shrimp farms, robbing coastal communities of storm
protection and natural water filtration and depriving fish of key
nursery habitats. So what does it look like to give
fish a break and let them recover? Protection can take many forms. In national waters,
governments can set limits about how, when, where,
and how much fishing occurs, with restrictions on certain
boats and equipment. Harmful practices, such as bottom
trawling, can be banned altogether, and we can establish marine reserves
closed to all fishing to help ecosystems restore themselves. There’s also a role for consumer awareness
and boycotts to reduce wasteful practices, like shark finning, and push fishing industries towards
more sustainable practices. Past interventions have successfully
helped depleted fish populations recover. There are many solutions. The best approach for each fishery
must be considered based on science, respect for the local communities
that rely on the ocean, and for fish as wild animals. And then the rules must be enforced. International collaboration is often
needed, too, because fish don’t care about our borders. We need to end overfishing. Ecosystems, food security, jobs, economies, and coastal cultures all depend on it.

  1. This video is liberal agenda. Those animals dont have feelings and dont care if you are using military hardware to catch them.

  2. Nope never, they will never disappear but fishing must be done moderation it will do us good but the reproduction time is slow, moderation understanding and knoledge is the key

  3. its a misconception that all sharks are endangered. most researches agree that sustainable shark fishing is possible.

  4. I'm sorry but shark fin soup have never been considered such a delicacy in Vietnam. I'm a Vietnamese. I, my family, my relatives, my friends,… have never tried it for sure. I think it just reflects a very very small group of people and it is not true for all (Vietnamses)

  5. Why dont we just catch small amounts of fish species then breed those fish, farm them, and let the fish in the wild live in peace

  6. I have pet turtles cuz my gold and fighting fish died
    Fighter fish:overfed
    Gold fish:underfed

  7. Well why should we eat fish then! Animals and humans attack together because humans kill animals but some animals are out there surviving by hiding.Animals and humans have to live in harmony between this species of earth

  8. it is mans destiny to destroy our world and ourselves. there are too many of us on this planet, we will fish the seas till the last fish is caught. then we all die 😂

  9. it PATHETIC that this video mentions NOTHING about ocean acidification , military sonar ,, climate change etc etc ,the worlds most prominent Oceanographer gave the ocean 17 years to stay alive about 6 years ago ..WAKE UP ,fishing or no fishing if the fish are DEAD they wont bite

  10. "There are many different ways to protect over fishing" omfg just stop eating fish that is like the only 100% effective solution

  11. And most the good fish ends up in our land fills we waste way more than we eat and that's every thing its putting stress on our planet

  12. as Asia is rapidly developing and Africa is also predicted to develop soon…overfishing will probably keep happening

  13. More than people eating fish, we should quastion those who allows such methods of fishing, it needs to be illegal. It is the core of a problem.

  14. My thing is, why isn't someone doing something to stop this! It's sad to see the ocean, which is filled with all kinds of oceanic creatures, resort to one day not having life in it at all smh.

  15. Thank god, we have good ministry of marine and fishery here. We often caught illegal fishing boats and sank them to the bottom of the sea. You can guess where am i….

  16. Help these fish to repopulate especially jaws jaws was only wating pple bc they killed his family donate now to ban this act
