Harvesting sharks

Sharks are often killed for shark fin soup. Fishermen capture live sharks, fin them, and dump the finless animal back into the water. Shark finning involves removing the fin with a hot metal blade.[89] The resulting immobile shark soon dies from suffocation or predators.[92] Shark fin has become a major trade within black markets all over the world. Fins sell for about $300/lb in 2009.[93] Poachers illegally fin millions each year. Few governments enforce laws that protect them.[citation needed] In 2010 Hawaii became the first U.S. state to prohibit the possession, sale, trade or distribution of shark fins.[94] From 1996 to 2000, an estimated 38 million sharks had been killed per year for harvesting shark fins.[91]
Shark fin soup is a status symbol in Asian countries, and is considered healthy and full of nutrients. Sharks are also killed for meat. European diners consume dogfishes, smoothhounds, catsharks, makos, porbeagle and also skates and rays.[95] However, the U.S. FDA lists sharks as one of four fish (with swordfish, king mackerel, and tilefish) whose high mercury content is hazardous to children and pregnant women.

The majority of shark fisheries have little monitoring or management. The rise in demand for shark products increases pressure on fisheries.[30] Major declines in shark stocks have been recorded—some species have been depleted by over 90% over the past 20–30 years with population declines of 70% not unusual
