Shark fin soup is a broth in which the fin supplies texture and almost nothing else: the fin is cartilage, essentially flavourless, and the taste comes from the chicken or ham stock it is simmered in.
The dish has marked status at Chinese banquets since the Ming dynasty, and the bill for it is paid somewhere other than the table. A study of Hong Kong auction records put 26 to 73 million sharks a year into the fin trade around 2000, and total shark mortality was still running near 80 million a year in 2019 despite two decades of finning bans.

What is actually in the bowl
A shark's fin is not meat. Strip the skin and the outer tissue and what remains is a bundle of stiff collagen fibres called ceratotrichia, the internal rods that hold the fin rigid in the water. Dried, they look like coarse noodles; soaked, boiled and shredded, they give the soup the springy, slippery strands that are the point of the dish. Cooks are open about the fact that fin has no taste, which is why it is cooked in a strong stock of chicken, ham or scallop.
That is worth stating plainly, because it reframes everything else on this page. Nobody is eating shark fin soup for the shark fin. They are eating it for texture and, far more importantly, for what serving it says about the host. The dish sits at weddings, business dinners and New Year banquets because it has always been the item on the menu that costs the most and takes the longest to prepare.
Nutritionally there is nothing worth defending either. Collagen is an incomplete protein, and the vitamins and minerals in the soup come from the broth and the garnish rather than the fin. The anatomy of the fins themselves is covered in understanding shark fins.
Where the tradition came from, and when it exploded
The usual account traces the dish to the Song dynasty, which began in 960, and it appears clearly in the record as an imperial banquet item under the Ming, from 1368 onward. Both versions of the story carry the same logic: a rare ingredient hauled from the sea, prepared over days, served to demonstrate that the host could afford it. For most of its history that was the whole of its distribution — a handful of courts and a very small number of households.
What the older telling of this story gets wrong is when it stopped being rare. The change was not the early nineteenth century. It came in the last four decades of the twentieth, as incomes rose across mainland China, Hong Kong and the Chinese diaspora, and a banquet dish that had been restricted to the wealthy became something a much larger middle class could put on a wedding menu. Industrial longlining arrived at the same moment and made the supply side possible.
Demand and catch climbed together through the 1980s and 1990s. The meaning of the dish never changed; only the number of people able to buy into it did, which means the pressure on sharks is recent even though the custom is not.
How the fins are taken
Finning at sea is the practice the campaigns are named after: a shark is hauled aboard, its fins are cut off, and the animal goes back over the side alive. Unable to swim, it sinks, and it dies of suffocation, blood loss or predation. The reason is storage economics — fins are a small fraction of a shark's weight and many times its value per kilo, so a hold filled with fins alone is worth far more than a hold filled with whole sharks.
Most major fishing nations have now outlawed the practice, and the effective version of the law is the fins-attached rule: sharks must be landed with their fins still naturally attached to the body, which removes the storage incentive entirely. The United States wrote this into the Shark Conservation Act of 2010 and the European Union adopted a fins-attached regulation in 2013. In 2022 the United States went further and banned the commercial trade in shark fins outright.
The uncomfortable part is what the data showed afterwards. Finning bans changed how sharks are killed without reducing how many die, because whole-shark landings rose to fill the gap and the meat trade absorbed the difference. Bycatch in fisheries aimed at tuna and swordfish accounts for a large share of the total.
The numbers, and where they come from
The figure everybody quotes — 26 to 73 million sharks a year — comes from a 2006 analysis of Hong Kong fin auction records, and it describes the trade around the year 2000 with a median near 38 million. It is a good number, but it is old and it is specific to fins. Later work counted total shark deaths from all causes and produced larger figures: roughly 100 million a year at the start of the 2000s, and around 80 million in 2019, of which some 25 million were species already listed as threatened.
What those killings have done to populations is measurable. A 2021 assessment of oceanic sharks and rays found global abundance had fallen 71% since 1970, with three quarters of the species assessed now facing extinction risk. Some individual species have done far worse than the average: hammerheads and oceanic whitetips, both prized for fin size and quality, are among the steepest declines recorded in any marine group.
Sharks are poorly built to absorb this. They mature late, carry few young and reproduce slowly, so a population fished down does not rebound the way a bony fish stock can. The mechanics of that are set out in why sharks are endangered, and the species-by-species picture is in are sharks endangered and the IUCN Red List entry.
The health claims, checked
Shark fin is sold in some markets as a tonic — for longevity, for virility, for resistance to cancer. None of it holds. The cancer claim descends from a 1990s book arguing that sharks do not get cancer; they do, and tumours including chondromas have been documented in sharks and rays for decades. Cartilage taken by mouth is digested like any other protein and does not reach a tumour in any recognisable form, and the clinical trials of shark cartilage products found no benefit.
There is a real health finding, and it runs the other way. Shark fin sampled in Hong Kong and elsewhere has repeatedly shown elevated mercury, which sharks accumulate as long-lived predators near the top of the food web. Fins have also been found to carry BMAA, a neurotoxic amino acid associated with neurodegenerative disease in other exposure studies.
The claim about sterility deserves a note of its own, because it appears on a great many pages including the older version of this one. No study has shown that eating shark fin causes infertility in men. What exists is a general association between high mercury exposure and reduced sperm quality, compressed by campaigners into a slogan. The mercury is real; the specific claim is not established.
What has actually changed
The demand side has moved further than most people realise. Hong Kong fin imports fell by roughly half between 2011 and 2013, and in December 2013 the Chinese government banned shark fin from official state banquets — a decision aimed at austerity rather than conservation, but one that removed a large block of institutional demand and, more usefully, removed the dish's association with propriety. Surveys through the 2010s tracked consumption falling in mainland cities, with Hong Kong and parts of Southeast Asia lagging behind.
Regulation has moved too. CITES listings that began with a handful of species in 2013 were extended in 2022 to the whole requiem shark family and the remaining hammerheads, bringing most of the fin trade under international control for the first time. Airlines and shipping lines have refused the cargo.
What has not changed is the total. Sharks are still dying at a rate near 80 million a year, and the pressure has shifted towards meat, liver oil and bycatch in industrial fisheries. Shark fin soup is the most visible part of the problem and no longer the largest.

Frequently asked questions
What is shark fin soup made of?
The fin contributes stiff collagen fibres called ceratotrichia, which soften into noodle-like strands when soaked and boiled. They have no flavour of their own. Everything that tastes of anything in the bowl comes from the stock, usually chicken, ham or scallop, plus the seasoning and garnish the cook adds.
How many sharks are killed for their fins?
A 2006 study of Hong Kong auction records put 26 to 73 million sharks a year in the fin trade around the year 2000, with a median near 38 million. Counting deaths from all causes gives a larger figure: roughly 80 million sharks killed in 2019, about 25 million of them threatened species.
Is shark finning still legal?
The practice of cutting fins at sea and discarding the body is banned in most major fishing nations, usually through fins-attached rules that require sharks to be landed whole. The United States banned the commercial fin trade outright in 2022. Enforcement at sea remains the weak point in almost every jurisdiction.
Does shark fin soup have health benefits?
No demonstrated ones. The fin is collagen, an incomplete protein, and the soup is nutritionally poorer than the stock it is made with. Claims about longevity, virility and cancer prevention have no clinical support, and trials of shark cartilage as a cancer treatment found no benefit for patients.
Is shark fin soup dangerous to eat?
It carries measurable risk. Sharks are long-lived predators high in the food web and accumulate mercury, and samples of fin sold in Hong Kong and elsewhere have repeatedly shown elevated levels. Fins have also been found to contain BMAA, a neurotoxic amino acid linked to neurodegenerative disease in exposure research.
Do sharks get cancer?
Yes. The claim that they do not comes from a 1990s popular book and was never supported by the evidence. Tumours including chondromas have been documented in sharks and rays for decades. Eating cartilage would not transfer any protection in any case, because it is digested like any other protein.
Has demand for shark fin soup gone down?
Substantially in some places. Hong Kong imports fell by around half between 2011 and 2013, and China removed the dish from official state banquets in December 2013. Consumption surveys in mainland cities tracked further falls through the decade, while Hong Kong and parts of Southeast Asia moved more slowly.
If finning is banned, why are shark numbers still falling?
Because the bans changed how sharks are killed rather than how many. Landings of whole sharks rose as fins-attached rules took effect, and the meat, liver oil and bycatch trades absorbed the difference. Global abundance of oceanic sharks and rays has fallen 71% since 1970 and has not recovered.
