Activists from Greenpeace East Asia and Greenpeace Mexico talk to the public as they hold up fake plastic swim bladders from the totoaba fish, to highlight the rampant illegal trade in the critically endangered fish which is being conducted by organised crime syndicates in Mexico, the United States and Hong Kong to feed growing demand for high end luxury seafood products in China, Hong Kong International Airport, Hong Kong, China. The trade is driving the last 97 vaquitas, the world's smallest and rarest marine cetacean, to extinction, as the gill nets that are being used by the Mexican fishermen to catch the totoaba fish in the Gulf of California are also accidentally killing the vaquita dolphins. Dried totoaba bladders are a prized delicacy in China, and if successfully smuggled to Hong Kong, can fetch prices as high as HK$5 million (EUR 591,000) according to a recent investigation by Greenpeace. Greenpeace is calling on the Hong Kong government to tighten customs enforcement and increase public awareness on the issue.
