Shark Fishermen Lobbying Hard to Profit from the Shark Fin Trade

With the loss of at least 90% of sharks worldwide, it would seem to be urgent to protect the ones that remain. Every global study of their status has reported a more dire situation than the last, and that the targeted hunt for the shark fin trade is responsible for their catastrophic depletion. Only one third of shark species are considered safe, and the most threatened are those accessible to fishing—those within about 1000 metres of the surface, or, for seafloor dwellers, 3000 metres in depth.

Shark fins are among the most expensive seafood products. The total declared value of the world trade in shark products is close to US$1 billion per year and it is associated with much illegal activity, including murder. To supply it, intense shark fishing spans all oceans. Yet, as top predators, sharks have incalculable ecological importance and their removal has grave effects on the ecosystems where they live, as failures cascade down through the inter-tangled networks.

Yet, shark fisheries scientists, advocates, and coalitions such as the Sustainable Shark Alliance (SSA), which represents shark fishermen, dealers, and processors—those who profit from the shark fin trade—continue to promote shark fishing, claiming that it is already sustainable, and will be more so.

But is this true, or just political promotion by industrial interests?

Sustainable Shark Fishing

A close examination of the best global scientific studies reveals that no shark fishery serving the shark fin market is sustainable. The markets for shark fins and shark meat have always been separate, and involve different species. Those currently considered sustainable are only a few that have targeted sharks for meat, in Australia and the USA. However, they are now being propped up by the value of the sharks’ fins and their long-term viability is questionable.

For example, the spiny dogfish fishery, on the Atlantic coast of the United States of America, is currently considered one of the most notable sustainable shark fisheries. The meat is sent to Europe and the fins to Asia. This fishery markets shark meat as a replacement for cod, the once plentiful fish from that region which is now gone. Since there is little market for shark meat in the country, the meat is sold under different names, such as “rock salmon.” 

 

But the stock of spiny dogfish in the western Atlantic shows wide fluctuations. It collapsed in the 1990s, and the American National Oceanic and Atmospheric Administration, Department of Commerce (NOAA), declared it to be rebuilt in 2010. However, globally, the species is listed by the International Union for Conservation of Nature (IUCN) as being vulnerable to overfishing, and it is critically endangered just across the Atlantic Ocean. Therefore, the population off the eastern coast of the USA is unlikely to be stable, either.

Dogfishes, like other species in the deep, cold waters of the northern continental slopes, have relatively low productivity. They produce fewer young per pregnancy and are longer lived than many other shark species. The bio-accumulation of mercury in their body tissues is greater, too, making this shark highly questionable as a choice to offer on the market as food.

Global analyses have shown that the level of threat to sharks through overfishing is usually greater than what is predicted by fisheries assessments. Such local assessments can underestimate the risk of collapse of global stocks of any given species, and have often caused such a collapse. 

Sharks are already extinct at St. Paul’s Rocks, for example, where no carcharhinid reef sharks have been seen in past decades though they were formerly plentiful. Such local extinctions are the warning signs of fisheries management failure and are the first steps on the road to global extinctions. 

Then there is the problem of by-catch. The quantities of most shark species taken as by-catch are not recorded, so some species can be at high risk of depletion without this being recognized.

A World Bank study, Sunken Billions, 2009, and Sunken Billions Revisited, 2017, has found that unsustainable fisheries management practices have led to globally depleted fish stocks that produce $83 billion less in annual net benefits than would otherwise be the case. Ninety percent of fisheries are over-exploited. To address this global crisis, the main requirement is that fishing effort is diminished, while at the same time, fish stocks must be rebuilt, and coastal ecosystems returned to a state of health. 

 

This study specifies that little is known about the actual carrying capacity of most fish stocks that are subject to commercial exploitation, and that fisheries’ data are often highly uncertain.

What becomes evident in the current political situation in the USA, in which shark fishing advocates are lobbying hard for the perpetuation of the shark fin trade, is that American fisheries are focusing on sharks with the intention of profiting from their fins, while the over-abundance of shark meat is being used in everything possible from make-up to dogfood.

However, the fisheries’ current plan to take the top predators, now that they have depleted the fish, is ecological folly. Shark production is much lower than fish production, and if these fishermen have their way, sharks will soon go the way of the cod and the many other species that they have fished out.

Sunken Billions predicts that social unrest will result from the necessary reduction of fishing effort that must come, because some fishermen will have to turn to other occupations. So the current outcry from the shark fishing industry has been predicted, and is understandable. The World Bank recommends that the fishing subsidies that have facilitated over-fishing in the past, be used to ease this social transition.

Problems with sustainability

While the idea of sustainability sounds good, the facts as found by the best science simply do not support the notion that sustainable shark fishing is possible to put into practice long-term. The scientific studies done to research the matter have revealed how few such fisheries are.

To begin with, pirate fishing takes one fifth of the total fishing revenue. Twenty-six million tons of catch are thought to be taken illegally each year by pirate industrial-scale fishing, and there is no effective authority to police international waters. 

 

The documented shark fin trade shows that fisheries have underestimated the numbers of sharks being killed by at least 400 percent, which shows just how unreliable fisheries’ data are.

 

Further, only a small fraction of the shark fin trade is documented. Most fins are imported from Asia where they have been sourced from many shark hunting nations, most of which do not keep species-specific catch statistics, so are impossible to trace.

When only the fins of the shark are valuable, when you apply the wise adage to use the whole animal, the question becomes, not “What do you do with the fins,” but “What do you do with the rest of the shark?”

Texas recently passed a law that required that all dead sharks shipped through the state have their fins naturally attached, so that the fishermen lost the profit from the sale of the fins. This income loss effectively closed down the Western Gulf of Mexico shark fishery in 2019. This shows the degree to which the shark fin market drives shark fisheries. 

Similarly, in Costa Rica and other South and Central American countries, sharks were considered undesirable and were not used for food prior to the 1980s. Then the inflated price of shark fins resulted in sharks from a wide variety of habitats being targeted for their fins alone. The ‘fins attached’ policies obligated fishermen to land fins attached to the bodies. So the shark fin industry’s surplus meat was put on the market for domestic consumption, resulting in merchants pushing the meat on local consumers and relying on the use of various other names to sell it. Now Costa Ricans alone are consuming about 2000 tons of shark meat a year and the situation is similar in many other countries.

This is a problem with mandating a ‘fins attached’ policy: it does not properly address overfishing. Worldwide, the tendency now is less discarding of the body of the shark, but without a lessening of mortality.

Toxic meat

The problem with loading shark meat into the local markets is that it is poisonous. For example, the Florida Fish and Wildlife Conservation Commission’s fishing rules specify a minimum size limit of 54 inches for about half of the shark species caught. At the same time, the Florida Advisory on Fish Consumption advises that no species of coastal shark longer than 43 inches should ever be eaten by anyone. Thus fishermen are specifically advised to catch large sharks, which are breeding females, and are too toxic to eat. 

This makes it clear that large species such as lemon and tiger sharks are being killed only for the value of their fins. 

Thus fisheries interests lobbying for the perpetuation of the shark fin trade are targeting an animal that is too toxic to eat, and is globally threatened, for the benefit of relatively few industry employees.

The inherent uncertainties

For a fishery to be sustainable, shark fishing mortality must be equal to, or lower than, the number of dead sharks that make up the ‘maximum sustainable yield.’ But in the case of sharks, those reference points are often not known or are very uncertain. The global studies done on shark depletion have emphasized the problems inherent in assessing the true situation, providing detailed descriptions of the difficulties on every level. 

 

For example, in 2015 the International Scientific Committee for Tuna and Tuna-like Species in the North Pacific Ocean analysed shortfin mako stocks using the most complete data available but it found that due to missing information, untested indicators, and conflicts in the available data, the assessment was impossible to make at all. 

 

This species was assessed on the IUCN Red List in 2000 as being ‘Lower risk/Near Threatened,’ and in 2009, it was reclassified as ‘Vulnerable.’ Then, in 2017, the shortfin mako fishery in the North Atlantic Ocean was reported by a fisheries study to be potentially sustainable. However, that same year, the stock assessment on the NOAA Fisheries website showed that this shark was overfished and that overfishing was occurring. IUCN subsequently re-classified the shortfin mako from ‘Vulnerable’ to ‘Endangered’ worldwide, with a decreasing population trend. So in 2019 USA fisheries began working on a management plan and urged fishermen to reduce catches voluntarily in the meantime.

Thus, fishery management in the USA, which claims to be the best in the world, allowed this species to go from ‘Lower Risk’ to ‘Vulnerable’ to ‘Endangered’ in less than 20 years, with no conservation action. Only now, in 2019, are they working on a plan. It is clear that the ‘sustainable fishery’ management approach is not working to maintain populations at healthy levels.

CITES protection

Listings by the Convention on International Trade in Endangered Species (CITES) are currently the only protection available for sharks. But in practice, such a listing only protects the animal from exportation, not from being fished in the first place. Protecting an animal with high market value is extremely difficult and such listings are opposed by shark hunting nations due to the high commercial value of the fins, so increasing effort is required to obtain them. Protection must be gained one species at a time, and only a few species are currently listed, while the shark fin market demands fins from all species.

Once separated from the shark, it is difficult to determine from which species any given fin has been taken, so enforcement is weak. Further, the only protection granted by a CITES listing is the need for a ‘Non-detrimental’ finding before the fins can be exported. This often undermines the protection originally intended for the species by the CITES listing.

Fisheries’ arguments

Whenever shark fishermen are threatened with the loss of their shark fin profits, they protest. Usually this involves claiming that if they don’t continue to kill the sharks, the animals will soon be out on the beaches eating people’s babies, and this is currently the case in the USA. The strong movement to block the shark fin trade there, has resulted in The Shark Fin Trade Elimination Act of 2019, which is now before Congress. 

But shark fisheries are fighting back, arguing that the shark fin trade should continue for the profit of American fishermen. It is fired by coalitions of shark fishermen, dealers, and processors, such as Sustainable Shark Alliance, and the shark fisheries scientists, lawyers, and lobbyists, who advocate their wishes. They promote H.R. 788, The Sustainable Shark Fisheries and Trade Act of 2019, and actually admit that without the profit from shark fins, shark fisheries in the USA will be shut down.

They reason that American shark fishermen fish sustainably, so they should be able to sell their shark fins on the lucrative shark fin market. They promote the idea that if only shark fins from sustainable fisheries are used for shark fin soup, this will put an end to shark finning worldwide, and those countries who continue to practice it will suffer. However the numbers reveal that the market for shark fins in the USA could never be filled by fins from sustainable shark fisheries, few as they are. Further, to support a trade responsible for such shark losses worldwide, is considered by many to be an ethical issue, on which the USA should be careful to remain on the good side.

Fisheries spokesmen claim that:

• If the shark fin trade is banned, more sharks will be killed, because fishermen will have to catch more sharks to make the same amount of money.
• The fins should be used because of the general principle that the whole shark should be used.
• Sharks are really being killed for meat, not for their fins.
• If American fishermen don’t kill the sharks and supply the shark fin trade, “bad actors” will kill them.
  
  

However, these arguments are not based on science, facts, or logic, and rely on political bias and rhetoric. While it sounds like a good idea to import, export, and sell products that only come from ‘sustainable’ fisheries, the The Sustainable Shark Fisheries and Trade Act of 2019 is completely unrealistic to put into practice. The problems of who would set the standard, who would lobby other countries to accept the USA’s evaluation of what is sustainable, who would monitor the program, research, and pay for it, are all unaddressed. Whether the American public would be willing to finance it through their tax dollars has not been mentioned.

Fisheries governance regimes are very expensive to set up and operate, and the cost varies depending on the type of measures implemented, ranging from scientific advice and management to monitoring, control, surveillance, and enforcement. Every country in the world with a shark fishery would need to be lobbied to pass sustainable shark fisheries management legislation. When laws are in place and enough data has been collected to determine what the sustainable catch rates might be for each species caught in every shark fishery, development and funding of management plans would need to be put in place, including staffing, training, purchase of equipment, and so on. Then, enforcement plans would need to be developed, implemented, and funded.

These costs tend to fall on the public sector while the benefits are enjoyed by fishermen.

All that is involved in the Sustainable Shark Fisheries and Trade Act—putting American practices into play on a global scale—would need to be maintained long-term, while somehow requiring every country to keep politics, financial self-interest, and corruption, to say nothing of criminality, out of the process. 

 

There is no international body that can force sovereign countries to do anything on this scale. Some countries, especially those with large fisheries, have consistently been resistant to controls on fishing based on scientific data. 

 

Europol reported in 2018 that illegal fishing of tuna was twice that of legal fishing in the Atlantic. If it is not possible to effectively manage a species for which there is probably more data than any other, the idea that the USA will create sustainably managed fisheries for all 500 shark species (and all fish species) throughout the entire world is absurd. 

 

Further, World Trade Organization agreements require that no country can favour the imports of one nation over another, nor ban imports of a product while still locally producing and exporting the product. The Sustainable Shark Fisheries and Trade Act would appear to be in direct violation of those agreements, and fisheries advocates have not stated how the USA will get around this.

To complicate matters, the USA itself obfuscates its records of its involvement with the shark fin trade. It records trade in dried shark fins only, under just one commodity code, while its exports of raw, frozen shark fins are classified as meat. Thus its official records are very misleading, so that fisheries’ advocates can easily make the case that the country scarcely contributes to the shark fin trade. However, other countries have reported exporting large amounts of shark fins to the country. In 2007, for example, other countries reported exporting 1,012 metric tons of shark fins to the USA, thirty-five times the figure of 28.8 metric tons reported by NOAA. 

 

At least several hundred tons of shark fins are consumed annually in the USA, and imports have been rising each year, in spite of the bans in such major centres as California and New York. Ninety-three percent of imports enter through the Los Angeles customs district, and in 2017 one-third of species traded in the Hong Kong shark fin market, (the central Asian market for fins), were found to be threatened with extinction. 

 

Conclusions

Sharks reproduce far more slowly than fish. While fish lay thousands of eggs, sharks are more like mammals. Female sharks take many years to reach reproductive age, then give birth to just a small number of offspring every one or two years. When fish stocks are commercially exploited, the most valuable stocks and larger individuals are targeted first. With this pattern applied over decades, global marine catches over time have comprised an increasing proportion of juvenile sharks, while the breeding adults are vanishing.

Sharks have high importance ecologically due to radial evolution into new vacant niches in the aftermath of several planet-wide extinctions. As a result, they are woven throughout the world’s aquatic ecosystems. As large animals at the top of the food chain, their removal is causing whole ecosystems to collapse. Further, due to the continuously increasing human population, the pressure upon them is likely to grow more intense as the years pass. 

 

A variety of indicators show an accumulation of extinction risk throughout the oceans as a result of many decades of overfishing. These are complicated by the effects of climate change—the melting icecaps, the changes in major oceanic current systems, ocean acidification, coral death, warming waters, and rising sea levels. Along with industrial and plastic pollution, these changes pose serious threats to marine life, including sharks. The World Bank’s recommendation that fishing effort be reduced to a point that allows the healthy recovery of coastal ecosystems, including their top predators, should be adopted until, with careful management and the allocation of many more Marine Protected Areas, the oceans regain a state of ecological stability. 

 

Priority should be given to local fishers who depend on the sea for their protein. Western consumers who are already eating too much protein, would just choose something else if fish were not on the menu. These are wild animals, and with the human population already so bloated, and growing fast, it is self-evident that no wild animal should be expected to support us.

For these reasons, no large-scale shark fishery is going to prove sustainable in the long-term. If history has taught us anything, it is that no species can stand up to sustained, targeted, commercial killing—not whales, not turtles, not fish, and not sharks. 

 

At the very least, sharks should be given the same protection now granted to sea turtles—complete protection from international trade.
