Sharks: Dying for a Bowl of Soup

Humane Society International

Every year, millions of sharks suffer painful deaths from the cruel and wasteful shark fin trade. Whether unintended "bycatch" by or caught specifically for their valuable fins, these animals have their fins removed and then—either dead or dying—are immediately cast back into the water. Shark meat is of low commercial value, so fishers save freezer space for highly valued fish and discard the sharks after the animals are "finned."

The market for shark fin soup, a traditional dish in east Asia, is driving this growing practice—an appetite that has contributed to the shocking decline of most large shark species over the past half-century.

As the chief predators of the ocean, sharks play an essential role in the balance of the marine ecosystem. Their overfishing leads to collapsing populations, which—along with that of other large predators—will likely lead to serious consequences for many other ocean species. The effects of shark overfishing are already being seen.

Shark fin soup

While shark fin has no flavor and very little nutritional value, it does provide texture to soup, not to mention handsome profits to an industry estimated to be worth $500 million per year. Fins are dried, de-skinned, boiled and sometimes bleached, and then made into soup by the addition of chicken or fish stock, which provides the flavor. The fins of certain species are considered more valuable because of the length and thickness of the "fin needles" that they contain.

Mainland China is the world's biggest end-market for shark fin. Because of its perceived value, serving shark fin soup at private functions is a way of honoring one's guests and signaling one's wealth and status. Chinese people frequently express the view that no self-respecting host would ever leave shark fin soup off the menu, particularly at weddings and other important social functions, for fear of losing face.

White gold

The international trade in shark fins has generated a highly lucrative industry in east Asia, with many shark fin dealers having multi-million dollar annual turnovers. Global Customs data show that over 100 countries are involved in the shark fin trade, the majority of them being exporters. The main consumer countries in Asia are mainland China, Hong Kong, Singapore, Taiwan, Malaysia and Thailand, but large volumes of shark fins are also imported into the US and the EU, to supply local Chinese communities.

The high commercial value of shark fins has led to gangland murders, with one fin trader killing another to warn others off his "patch." In some parts of the world, mafia-style organizations, such as the Chinese Triads, are in complete control of the trade.

Illegal activity

There have been numerous seizures of illegal shark fins around the world. In some cases, the sharks were caught in areas where shark fishing is prohibited. In other cases, the vessels were apprehended in areas where finning is illegal and were found to be carrying only fins, or insufficient shark carcasses to account for the number of fins on board—in other words, the sharks had been finned.

Some countries, such as Costa Rica, have strong shark finning regulations but lack the resources to enforce them. As a result, sharks are often finned in totally protected sea areas where all shark fishing is banned. In such cases, the many seizures that have taken place are likely to represent only the tip of the iceberg.

Mercury with your soup?

Laboratory tests in Hong Kong and Thailand have uncovered levels of mercury in shark fins that far exceed recommended safe levels. Mercury is a neurotoxin that can cause extensive damage to the nervous system and to fetuses. The increasing consumption of shark fin soup may well cause widespread public health problems resulting from mercury poisoning. In addition, The Washington Post reported concern that shark fins have been processed in China using industrial chemicals.
