The Atlantic bluefin tuna (Thunnus Thynnus) (or "tunny" as it was known in Britain at the time) is a large and powerful fish, arguably the strongest fish in the world, which is frequently the target of big-game fishermen.
Southern bluefin tuna: found in southern hemisphere waters of all the world's oceans: T. orientalis: Pacific bluefin tuna: found widely in the northern Pacific Ocean and locally in the south: Formerly known as northern bluefin tuna. T. thynnus: Atlantic bluefin tuna: found in both the western and eastern Atlantic Ocean, and also in the ...
Atlantic bluefin tuna, the largest member of this genus, can grow to 15 feet (4.6 m) long and weigh up to 1,500 pounds (680 kg). All tunas are extremely strong, muscular swimmers, and the yellowfin tuna is known to reach speeds of up to 50 miles per hour (80 km/h) when pursuing prey.
A tuna (pl.: tunas or tuna) is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae family.The Thunnini comprise 15 species across five genera, [2] the sizes of which vary greatly, ranging from the bullet tuna (max length: 50 cm or 1.6 ft, weight: 1.8 kg or 4 lb) up to the Atlantic bluefin tuna (max length: 4.6 m or 15 ft, weight: 684 kg or 1,508 lb), which ...
Thunnus (Thunnus) is sometimes referred to as the bluefin group and comprises five species: subgenus Thunnus (Thunnus) T. alalunga (Bonnaterre, 1788) – albacore; T. maccoyii (Castelnau, 1872) – southern bluefin tuna; T. obesus (Lowe, 1839) – bigeye tuna; T. orientalis (Temminck and Schlegel, 1844) – Pacific bluefin tuna
Species lengths vary from the 20 cm (7.9 in) of the island mackerel to the 4.58 m (15.0 ft) recorded for the immense Atlantic bluefin tuna. Scombrids are generally predators of the open ocean, and are found worldwide in tropical and temperate waters. They are capable of considerable speed, due to a highly streamlined body and retractable fins.
The technique, in its most simple iteration, consists in setting up net barriers to trap the tuna when they migrate into the Mediterranean Sea from the Atlantic Ocean (February to July), on their way to spawn and until recently, on their return journey, ("al revés"); the bycatch contains, among others, bullet tuna (auxis rochei), little tunny ...
