Albacore are caught at a young age in the cold northern waters of the Pacific Ocean.
They are a migratory fish with long pectoral fins, bullet-shaped streamlined-bodies, adapted to fast continuous-swimming in the open ocean. They can be found in enormous schools up to 30 kilometres wide, and can swim at speeds up to 80 kilometres per hour.
Albacore make for a better tuna choice. They can live to 12 years. But are harvested young, at 2 to 3 years, before they can accumulate significant amounts of pollutants.
The Marine Stewardship Council has certified Albacore troll-caught in the North Pacific Ocean as a sustainable fishery.
Note: Bluefin and Yellowfin are high in mercury and should be eaten infrequently if at all. Bluefin are at risk for becoming an endangered species. According to the MSC, all populations of Bluefin are over-fished, and some Yellowfin stocks are in decline.
