"China might be cracking down on luxury spending in watches, cars, banquets and really foul liquor. But the market for pricey fish parts continues relatively unabated."
"US border officials recently busted a ring smuggling bladders of an endangered fish used for medicinal Chinese soups (here are some images of these prized bladders). The amount of bladders they seized could have sold for more than $3.6 million, said prosecutors. And there are many other smuggling rings out there.
The totoaba, which is native to the Gulf of California, can grow to six feet long and live up to 25 years. Chinese medicine prizes a tubular organ that regulates the totoabas' buoyancy; the bladder, of sorts, is thought to help promote fertility. According to one report, a similar fish native to Chinese waters called a bahaba, which is also coveted for its bladder, has been known to fetch as much as 3 million RMB ($487,000) per fish -- and there's plenty of evidence of a thriving black market even though it's nearly extinct and listed by the Chinese government as a "protected species" (links in Chinese)."
