Wildlife conservationists, who have long railed against the popularity of shark fin soup, are finally seeing signs that consumption is dropping as young Asians become aware of the environmental impact of this much prized dish.

Added to that is the global financial crisis, which is causing Asians to tighten their belts and either cut down on visits to restaurants or order more frugally from menus.

A symbol of wealth and status in Chinese culture, shark fin soup has long been an essential part of banquet celebrations for weddings and to welcome in the Lunar New Year.

Until recently, only the rich could afford the soup. But demand has soared in recent years, hand-in-hand with rising affluence in East Asia. The quantity of shark fins demanded, around 800,000 metric tonnes a year, has caused a sharp decline in shark numbers. About 20 percent of all shark species are now endangered.

Wildlife conservationists also decry the killing of sharks through "finning", whereby the fins are cut off and the live shark is tossed back into the sea. Unable to swim properly, the shark suffocates or is killed by predators.

Tastes have changed along with awareness for young Asians.

Shang-kuan Liang-chi, a National Taiwan University student who has tried the crunchy jelly-like dish twice at formal events, prefers other food and avoids a shark fin restaurant near campus. "University students never go in there," he said.

Even chefs are hoping to turn the tide. At Singapore's Annual Chefs' Association dinner, shark fin traditionally served at the occasion was taken off the menu.

"It is much harder to stop serving shark's fin in our restaurants as the consumers still demand it. However, in our personal capacity, we can make a stand," said Otto Weibel, a food manager at one of Singapore's top hotels.

Global entertainment giant Disney bowed to pressure from animal rights activists and took the delicacy off its menu when it opened Hong Kong Disneyland in 2005.

Some Asian fishery authorities have banned "finning" and monitor boats for illegal catches of endangered species.

"We care a lot about the problems that environmental groups have raised," said Chen Tain-shou, Taiwan Fisheries Agency deputy director-general.

Authorities in south China recently rescued a nurse shark from a tank after learning that it was to be slaughtered and its fins turned into soup for a 70-person banquet.

Shark fin sellers say their sales have also been tested by the economy. With Taiwan, Singapore and Hong Kong in recession, the restaurant business is flagging. Older consumers would buy more in better times, they say.
