Abstract(s)
Os atuns pertencem a uma vasta família de peixes oceânicos denominada Scombridae e que inclui, para além do que se designa popularmente como atum, as cavalas, bonitos, serras e wahoos. Todas possuem hábitos migratórios, crescimento rápido e muitas apresentam, juntamente com os espadartes e espadins, uma característica única nos peixes – são endotérmicos ou seja, são capazes de reter o calor metabólico gerado para exercer funções vitais em águas frias sobretudo a natação rápida.
Nos Açores conhecem-se nove espécies de Scombridae entre elas os atuns mais procurados pelas frotas pesqueiras: Rabilo Thunnus thynnus, Voador ou Albacora T. alalunga, Galha à ré T. albacares e Patudo T. obesus.
ABSTRACT: Tunas belong to a large family of oceanic fish called Scombridae, which includes, in addition to what is popularly referred to as tuna, mackerels, bonitos, and wahoos. All have migratory habits, fast growth and many have, along with swordfish and marlin, a unique feature in fish - they are endothermic i.e. they are able to retain their generated metabolic heat to perform vital functions in cold waters and that naturally includes fast swimming. Nine species of Scombrids are known in the Azores and amongst them the tunas are certainly the most sought by fishing fleets: Bluefin Thunnus thynnus, Albacore, T. alalunga, Yellowfin T. albacares and Bigeye T. obesus.
