Tuna Tuna Tuna!
There are seven commercial and sport-caught tunas, as well as several related species, all of which are members of what is called the scombrid family. To get enough oxygen to sustain themselves, tuna swim with their mouths open to allow high volumes of water to pass over their gills. If a tuna were to stop swimming it would die, both from a lack of oxygen and gravity, since it would sink to the bottom because it is heavier than water.
Commercially caught tunas consist of albacore, bigeye, blackfin, bluefin, bonito, skipjack, and yellowfin. Yellowfin, taken in the eastern Pacific and tropical Atlantic, makes up the biggest U.S. commercial catch. Albacore, caught in the eastern Pacific, is the true "white-meat" tuna; skipjack, caught throughout the world in tropical and subtropical waters, makes up the second largest U.S. commercial catch; bigeye is caught mostly in tropical waters; blackfin is caught commercially only in the Caribbean and off South America; the very large bluefin Bluefin tuna, Thunnus thynnus, are among the largest and fastest marine fish. Also known as Horse Mackeral, (not around here!) an adult may weigh 1,500 pounds and swim up to 55 miles per hour. It is dark steel blue above with a silvery sides and belly. Prized as sushi in Japan, bluefins are also among the most valuable fish: individual bluefins can bring as much as $20,000 at U.S. docks The widely distributed bonito is used largely as pet food. Canned tuna makes up 25% of all seafood consumed in the United States.
The current recreational daily bluefin tuna retention limit is FOUR fish per vessel, measuring 27 to less than 73 inches curved fork length (i.e., any combination of the school, large school, or small medium size class). Angling category vessels in all areas are also allowed one large medium or giant "trophy" bluefin (measuring 73 inches curved fork length or greater) per vessel per fishing year. All bluefin must be reported. The Angling category yellowfin tuna daily retention limit is 3 yellowfin/person. The minimum size for yellowfin and bigeye tuna is 27" curved fork length.
