Tuna

Tuna are large, fast-swimming marine fishes in several genera of the mackerel family Scombridae. Many species range widely across the open ocean and support major fisheries.

Scombridae: A family of marine fishes that includes tunas, mackerels, bonitos, and Spanish mackerels. Tuna belong to this family, whose streamlined members share adaptations for fast swimming.
Atlantic bluefin tuna: A large tuna species native to the North Atlantic Ocean and adjacent seas. Its enormous size and history of intensive fishing make it a prominent tuna case.
Purse seining: A fishing method that encircles a school with a net whose bottom can be drawn closed. Purse seiners catch large schools of tuna, sometimes around floating objects.
Tuna fisheries: Commercial and subsistence fisheries that catch tuna for food and other products. These fisheries turn tuna abundance and migration into a global industry.
Mackerel: Common name for several fast-swimming marine fishes, including species in the family Scombridae. Mackerels share tuna's family but generally differ in size, body form, and long-distance migrations.
Thunnini: A tribe of scombrid fishes comprising tunas and closely related genera. This taxonomic group contains the principal tuna lineages.
Pacific bluefin tuna: A bluefin tuna species found in the North Pacific Ocean. Its trans-Pacific migrations connect distant feeding and spawning grounds.
Longline fishing: A fishing method using a main line with many baited hooks attached to branch lines. Longlines target tuna in open water but can also catch sharks and seabirds.
International Commission for the Conservation of Atlantic Tunas: An intergovernmental organization that coordinates conservation and management of Atlantic tuna and related species. It sets regional measures for fisheries targeting Atlantic tuna.
Bonito: A common name for several predatory scombrid fishes closely related to tuna. Bonitos resemble tuna and are sometimes marketed as tuna, but belong to distinct genera.
