Qué saber sobre tunas
Una guía de campo clara centrada en hábitat, identificación, comportamiento y conservación sin enterrar lo útil.
Tuna belong to the tribe Thunnini within the mackerel family Scombridae and comprise 15 species across five genera. Sizes vary greatly, from bullet tuna (about 50 cm and 1.8 kg) to Atlantic bluefin tuna (up to 4.6 m and 684 kg; averages around 2 m and may live up to 50 years). Tuna are active, agile predators with sleek, streamlined bodies and are among the fastest-swimming pelagic fishes; yellowfin tuna can reach speeds up to 75 km/h (47 mph). Tuna, opah, and certain mackerel sharks are among the few fishes capable of maintaining a body temperature higher than the surrounding water. Found in warm seas, tuna are extensively commercially fished for food and are popular as bluewater game fish. Overfishing has put some tuna species, such as southern bluefin tuna, at risk of extinction.
Some tuna species have been driven toward extinction risk due to extensive commercial fishing and overfishing.
Pelagic, active and agile predator; among the fastest-swimming open-ocean fishes, capable of short bursts at high speed.
