Over Fishing  of  TUNA

Fished by more than 70 countries, tuna are marketed in fresh, frozen or canned form. Tuna species are critical to both commercial and recreational fisheries as a result of this high international demand, many stock are exploited and over fished. Over fishing of one species can disrupt the health and balance of the entire marine ecosystem. There are seven commercially caught tunas that are core to creating sustainable fishing practices: Albacore, Bigeye, Blackfin, Bluefin, Bonito, Skipjack, and Yellowfin. Yellowfin comprises the largest  U.S. commercial catch. Albacore, which is caught in the eastern Pacific, is considered  the true "white-meat" tuna.  Skipjack makes up the second largest U.S. commercial catch. Bigeye is primarily fished in tropical waters. Blackfin is caught commercially in the Caribbean and off South America. The large Bluefin is a highly prized sport catch  because of it's large size. The Bonito is widely used in pet foods.
