The Shark Fin Soup Industry

The fin contributes no flavour to the dish. It is there for texture and for status, and that is the whole reason a global trade grew around it.

The Shark Fin Soup Industry
The Shark Fin Soup Industry
Dried fins are among the most valuable products taken from the sea, which is precisely the problem.
In short

Shark fin soup is a Chinese banquet dish in which stewed fin cartilage is served in a stock made from chicken or ham; the fin itself is close to tasteless and is used for its stringy texture and its cost. Demand for it built a fin trade that, at its peak, moved the fins of tens of millions of sharks a year.

The trade is smaller than it was and better regulated, but total shark fishing mortality has not fallen with it, because the meat market grew as the fin market shrank. The pressure moved rather than stopped.

What shark fin soup actually is

The fin arrives at the table as a mat of pale threads. They are ceratotrichia, the fibrous rods of elastic protein that stiffen a shark's fin the way the rays of a bony fish's fin are stiffened by bone. Dried, soaked and simmered, they hold their shape in hot liquid and give nothing in return: the flavour comes from the chicken, ham or scallop stock around them. Analyses have found no nutritional advantage, and fins of large predatory species regularly test high for mercury.

So the dish is about cost and ceremony rather than taste. It appears at weddings, at New Year banquets and at business dinners, where serving it signals that the host has spent money on the guests. That is a real cultural function and it is why the trade proved so resistant to argument.

The history is usually stretched. Pages repeating that shark fin was eaten at Han dynasty courts more than 2,200 years ago are quoting a claim that the food-history literature does not support; the documented record of fin as a banquet delicacy runs from the Song period and becomes firm under the Ming, from the fourteenth century onward. The Chinese name translates as "fish wing", which is one reason many diners were slow to connect the dish to a shark at all.

Finning, and why the rest of the shark goes overboard

Finning is the practice of cutting the fins from a shark at sea and throwing the body back, usually while the animal is still alive. Without its fins it cannot swim, so it sinks, suffocates or is eaten. The logic is economic: fins are worth many times more per kilogram than meat, and hold space is finite, so a boat that lands only fins can work far longer before returning to port.

Shark meat is cheap partly because of the animal's chemistry. Sharks hold urea and trimethylamine oxide in their tissues for buoyancy and osmotic balance, and once the fish dies the urea breaks down into ammonia, so the flesh has to be bled and processed quickly or it turns. Liver oil, skin, cartilage and jaws have their own smaller markets.

The standard regulatory response is a fins-naturally-attached rule: the shark must be landed whole, fins still on the carcass. It is enforceable at the dockside, it removes the incentive to dump bodies, and the European Union adopted it without exception in 2013. It does not, by itself, reduce the number of sharks caught — it only changes what happens to them after the catch, which is a distinction the older campaign material tends to blur.

Shark Finning Facts
Finning removes the valuable part and discards the animal, which is why landing rules now insist the fins stay attached.

How many sharks the trade really takes

Catch statistics reported to fisheries bodies have always been an undercount, so researchers worked backwards from the market instead. A 2006 study reconstructed the fin trade from Hong Kong auction records and put the number of sharks whose fins entered it at between 26 and 73 million a year around the turn of the century, with a central figure near 38 million — three to four times the biomass that official landings implied.

Totals for all shark fishing, not only the fin trade, were later estimated at roughly 100 million a year for 2000, with a wide range around that figure, and at about 80 million a year for 2019, of which some 25 million were species already assessed as threatened. The uncomfortable finding is that the more recent work shows no decline: fin consumption in Hong Kong and mainland China has fallen substantially since around 2011, but demand for shark meat, liver oil and cartilage picked up the slack.

The older claim that a third of open-ocean shark species are threatened has also been overtaken. The 2021 global assessment of oceanic sharks and rays found roughly three-quarters of them threatened with extinction, and put the decline in global oceanic abundance since 1970 at about 71 per cent. Species-level detail sits on are sharks endangered and why sharks are endangered.

What the law has done since

The picture has changed more than the campaign leaflets suggest. Canada banned the import and export of shark fins in 2019, the first G20 country to do so, which retires the old line that Canadian finning bans were meaningless because imports continued. The United States went further at the end of 2022 with a federal law making it illegal to possess, buy or sell shark fins across the country, after a decade of state-level bans; a Toronto by-law went the other way and was struck down in court for exceeding the city's jurisdiction.

The larger change was at CITES. In 2022 the parties listed the whole requiem shark family and the remaining hammerheads on Appendix II, so that trade in their fins now requires permits certifying legal and sustainable sourcing. Between them those groups account for the great majority of fins reaching the market. Enforcement rests on identification, and that has improved: fins that once could not be told apart by eye are now matched to species by DNA.

None of this addresses bycatch, which kills sharks that nobody set out to catch. If you want the short version of what an individual can usefully do, it is on ten easy ways to help save sharks, and the species most exposed to the trade — scalloped hammerhead, blue shark, shortfin mako — have their own pages in the species guide.

Frequently asked questions

What does shark fin soup taste like?

It tastes of the broth. The fin contributes texture rather than flavour: soaked and simmered, the cartilage separates into soft threads with a slight chew, and the taste in the bowl comes from the chicken, ham or seafood stock it is cooked in. Blind comparisons with imitation fin made from other ingredients are notoriously hard to call.

Why is shark fin soup so expensive?

Because scarcity and ceremony, not cooking, set the price. Dried fin is bought by weight at figures far above shark meat, the preparation takes days of soaking and simmering, and the dish functions as a display of generosity at weddings and banquets. Prices quoted per bowl vary enormously by city, restaurant and grade of fin.

How many sharks are killed for their fins each year?

The best reconstruction of the trade, based on Hong Kong auction records, put it between 26 and 73 million sharks a year around 2000, with a central estimate near 38 million. Fin consumption has fallen since, but total shark fishing mortality has not, because demand for shark meat and liver oil has grown.

Is shark finning illegal?

Finning at sea is banned in most major fishing nations, usually through a rule requiring sharks to be landed with their fins still attached. Trade is a separate question. Canada banned fin imports and exports in 2019 and the United States banned the domestic fin trade in 2022, but many countries still allow the sale of fins from legally landed sharks.

Does eating shark fin have health benefits?

No published evidence supports the traditional claims. Fin cartilage is largely structural protein with no unusual nutritional value, and the cartilage-cures-cancer idea has been tested and not borne out. There is a documented risk in the other direction: fins from large predatory sharks accumulate mercury, and testing has repeatedly found high concentrations.

Did shark fin soup really start in the Han dynasty?

That claim circulates widely but is not supported by food historians. References to shark fin as a banquet dish appear in the Song period and the delicacy becomes firmly established under the Ming dynasty, from the fourteenth century. The much older dates usually trace back to promotional writing rather than to any documented source.
