baited with herring or other similar fish, fished from the bottom with cannonball weights of up to 36 ounces on a slider. The survival rate of caught and released halibut is 95 percent due to the lack of having a swim bladder and not severely suffering from changes in water pressure (as long as the captured halibut is in excellent condition). Farming Due to its popularity as a food fish, Atlantic halibut has attracted investment in fish farming. As of 2006, five countries—Canada, Norway, the UK, Iceland and Chile—were engaged in some form of Atlantic halibut aquaculture production. Conservation status In 1996, the IUCN rated it as Endangered and placed it on its Red List. The Atlantic halibut is a US National Marine Fisheries Service Species of Concern, one of those species about which the U.S. Government's National Oceanic and Atmospheric Administration has some concerns regarding status and threats, but for which insufficient information is available to indicate a need to list the species under the U.S. Endangered Species Act (ESA). The American Fisheries Society has classified the species as "Vulnerable". In 2010, Greenpeace International added the Atlantic halibut to its seafood red list of "fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries." The Atlantic halibut has been on the endangered species list since 1996 due to overfishing since it became commercially important during the 19th century since the great meat demand of the halibut and being one of the largest flatfishes and essentially being easy to capture.
