Modern Slavery and the Collapse of Fisheries

Illegal, unreported and unregulated fishing accounts for a staggering 20-50% of the global catch. It is one reason fish stocks are plummeting: just a fifth of commercial species are sustainably fished. Illegal operators rob mostly poor coastal states of over $20bn a year and threaten the livelihoods of millions of small fishermen. A huge amount of illicit fishing happens on licensed boats, too. They might catch more than their quota, or falsely declare their catch as abundant albacore tuna instead of the more valuable bigeye. In port fisheries inspectors are always overstretched. If an operator is caught, for instance, fishing with too fine a net, the fine and confiscation are seen as a cost of doing business. Many pay up and head straight back out to sea.

The damage from illicit fishing goes well beyond fish stocks. Operators committing one kind of crime are likely to be committing others, too—cutting the fins off sharks, or even running guns or drugs. Many are also abusing their crews… A lot of them are in debt bondage…. Unscrupulous captains buy and sell these men and boys like chattel

Too often, the ultimate beneficiaries of this trade are hard to hook because they hide behind brass-plate companies and murky joint ventures. Pursuing them requires the same kind of sleuthing involved in busting criminal syndicates. An initiative led by Norway to go after transnational-fisheries crime is gaining support. Much more cross-border co-operation is needed.

At sea, technology can help. Electronic monitoring promises a technological revolution on board—Australian and American fleets are leading the way. Cameras combined with machine learning can spot suspicious behavior and even identify illicit species being brought on board…. Equally, national regulators should set basic labor standards at sea. If countries fail to follow the rules, coastal states should bar their fishing fleets from their waters. Fish-eating nations should allow imports only from responsible fleets.

Above all, governments should agree at the World Trade Organization to scrap the subsidies that promote overfishing. Of the $35bn a year lavished on the industry, about $22bn helps destroy fish stocks, mainly by making fuel too cheap. Do away with subsidies and forced labor, and half of high-seas fishing would no longer be profitable. Nor would that of China’s environmentally devastating bottom-trawling off the west African coast.

Just Forbid It – Fishing: Fishing and Marine Protected Areas

Fish, whether wild caught or farmed, now make up nearly a fifth of the animal protein that human beings eat….In this context, running the world’s fisheries efficiently might seem a sensible idea. In practice, that rarely happens. Even well-governed coastal countries often pander to their fishing lobbies by setting quotas which give little respite to battered piscine populations. Those with weak or corrupt governments may not even bother with this. Deals abound that permit outsiders legal but often badly monitored access to such countries’ waters. And many rogue vessels simply enter other people’s fishing grounds and steal their contents.

There may be a way to improve the supply side: increase the area where fishing is forbidden altogether.  This paradoxical approach, which involves the creation of so-called marine protected areas (MPAs), has already been demonstrated on several occasions to work locally. A new study “A global network of marine protected areas for food “in the Proceedings of the National Academy of Sciences…explores the idea of extending MPAs elsewhere. If the right extensions are picked designating a mere 5% more of the world’s oceans as MPAs—which would triple the area protected—could increase the future global catch of the 811 species they looked at by more than 20%. That corresponds to an extra 10m tonnes of food a year.

The idea that restricting fishing would permit more fish to be caught may seem counterintuitive, but the logic is simple. Fish in MPAs can grow larger than those at constant risk of being pulled from the ocean. Larger fish produce more eggs. More eggs mean more fry. Many of these youngsters then grow up and move out of the safe zone, thus becoming available to catch in adjoining areas where fishing is permitted…

MPAs are especially beneficial for the worst-managed areas, most of which are tropical—and in particular for overfished species…They also have the virtue of simplicity. The setting of quotas is open to pressure to overestimate of how many fish can safely be caught…This is difficult enough for countries with well-developed fisheries-research establishments. For those without such it is little more than guesswork…Setting the rules for an MPA is, by contrast, easy. You stick up a metaphorical sign that says, “No fishing”. Knowing who is breaking the rules is easy, too. If your gear is in the water, you are fishing illegally.

When the Fish are Gone: As Bad as it Could Get in the Yangtze River

China imposed a 10-year commercial fishing ban in January 2020  on the Yangtze – the first ever for Asia’s longest river – in a bid to protect its aquatic life.  Facing dwindling fish stocks and declining biodiversity in the 6,300km (3,915-mile) river, the Chinese government decided seasonal moratoriums were not enough. The ban will be applied at 332 conservation sites along the river. It will be extended to cover the main river course and key tributaries by January 1 2021, according to a State Council notice.   Dam-building, pollution, overfishing, river transport and dredging had worsened the situation for the waterway’s aquatic species.  Fishermen using nets with smaller holes and illegal practices such as the use of explosives or electrocution have also contributed to the river’s decline

 President Xi Jinping warned that the Yangtze River had become so depleted that its biodiversity index was as bad as it could get, saying it had reached what could be described as the “no fish” level… Back in 1954, the annual catch from the Yangtze was about 427,000 tonnes, but in recent years it had been less than 100,000 tonnes.
According to an official estimate, about 280,000 fishermen in 10 provinces along the Yangtze River will be affected by the ban. Their 113,000 registered fishing boats will be grounded or destroyed. The government has allocated funds to help those affected find alternative work and provide them with welfare and retraining. To counter illegal fishing, he said river authorities would be equipped with speedboats, drones and video surveillance systems. Fishermen would also be recruited to patrol the river.

Unwanted Fish: Another Waste

Long before fillets reach your dinner plate, lots of seafood is thrown away. Overboard, actually. As fishing crews sort through their catches, they toss unwanted fish back into the sea—as much as 20% of the global catch. The vast majority die. On 1 January, 2019 the wasteful practice became illegal in waters of the European Union. Scientists believe the policy will lead to more efficient fisheries and eventually boost stocks, while incentivizing more selective fishing gear and strategies. But in the short term it could mean hardship for the industry and perhaps even compromise fisheries data, if hidden cheating becomes widespread.

Few expect all fishing vessels to obey the discard ban. “Put yourself in the boots of a fishermen who can see he will run out of quota for a species. If he does, he would have to tie up for the rest of the year. He might have to sell the boat, or sell the house,” says Barrie Deas, CEO of the National Federation of Fishermen’s Organisations in York, U.K. “What’s he going to do?”  Scofflaws could jeopardize not just fish stocks, but also data about how they are faring. Researchers, who suggest catch levels to regulators, get their discard data largely from independent observers on just a few boats—less than 1% of the EU fleet. Observed boats are now likely to discard much fewer fish than other vessels, leaving an official undercount of the discard rate and a falsely rosy picture of how heavily stocks are fished, says Lisa Borges, a fisheries biologist who runs a consultancy called FishFix in Lisbon. “It could bring about a very big, negative change,” Borges says. “I get very worried about European fisheries management.”

Environmentalists want to toughen up enforcement by installing cameras on ships, the practice in New Zealand and a few other places with discard bans. But Voces de Onaindi says this is impractical on some vessels and raises privacy concerns. Countries where discard bans have succeeded, including Norway and Iceland, have gradually introduced incentives and controls to develop the economic use of unwanted fish and create a culture of regulatory compliance. Those steps, Andersen says, lessen conflict but can take decades to achieve.

Fish Poachers in Africa

In Sierra Leone nearly half the population does not have enough to eat, and fish make up most of what little protein people get. But the country’s once-plentiful shoals, combined with its weak government, have lured a flotilla of unscrupulous foreign trawlers to its waters. Most of the trawlers fly Chinese flags, though dozens also sail from South Korea, Italy, Guinea and Russia. Their combined catch is pushing Sierra Leone’s fisheries to the brink of collapse.

Sierra Leone is not alone in facing this crisis. According to the UN’s Food and Agriculture Organisation, 90% of the world’s fisheries are dangerously overexploited. The Africa Centre for Strategic Studies, a think-tank funded by America’s defence department, reckons that about a quarter of fish caught off Africa’s shores are taken illegally.

Regulation of Deep-Sea Fishing

A study published in 2009 suggested that in all but the deepest of their waters—those with a seabed closer than 1,500 metres to the surface—yields had dropped by 70% over 25 years. Even in the abyss below that depth, the fall was 20%. To try to stem this decline the European Union, which regulates fishing in much of the area, is proposing to limit the depth at which trawling can take place. This would, in effect, create a marine reservoir below that level, a form of protection additional to the system of species-specific quotas that already exists. The question is where the line below which trawl-gear is forbidden should be drawn. And, until now, there have been few scientific data to inform that decision.
This has just changed, however, with the timely publication, in Current Biology, of a study by Jo Clarke of Glasgow University and Francis Neat of Marine Scotland Science, a government agency. Their work suggests that the appropriate cut-off would be at a depth of 600 metres—below which the ecological damage caused by trawling increases substantially.

Ms Clarke and Dr Neat derive their conclusion from data collected between 1978 and 2013 by Marine Scotland Science and the Universities of Aberdeen and St Andrews. These data record species caught, and also the depths of the trawls that caught them, which ranged from 250 to 1,500 metres.

The researchers note that biodiversity increases with depth. On average, an extra 18 fish species show up with each 100-metre increase. Many of these, though, are of little commercial value. Such so-called by-catch gets thrown back, but by then most of it is dead. And that, particularly because deep-sea species tend to grow more slowly than those which live near the surface, and have lower fecundity rates, can have profound effects on ocean ecology.  Trawls at 300 metres, Ms Clarke and Dr Neat found, have a ratio of catch to by-catch (in terms of weight) of five to one. At 600 metres the ratio is around three to one. At 800 metres, though, it is ten to nine; at 1,000 metres one to one; and at 1,200 metres, one to two.

Based on these findings, Ms Clarke and Dr Neat suggest that a trawl limit of 600 metres would be a suitable compromise between commercial reality and ecological necessity.
