Spearfishing with scuba gear is widespread among recreational divers. Restrictions in Norway are limited to anadrome species, like Atlantic salmon, sea trout, and lobster. [31] In Mexico a regular fishing permit allows spearfishing, but not electro-mechanical spearguns. Spearfishing with scuba gear is illegal and the use of power heads as well.
Japan is both the biggest consumer and the leader in tuna farming research. [17] [18] Kinki University of Japan first successfully farmed already-hatched bluefin tuna in 1979. In 2002, they succeeded in breeding them, and in 2007, the process was repeated for a third generation. [19] [20] [21] This farm-raised tuna is now known as Kindai tuna ...

In 2000 a 76-year-old pensioner using a fishing rod for the first time landed the largest tuna caught off the British Isles for nearly 50 years. Off the north-west coast of Ireland Alan Glanville caught a 353-pound (160 kg) fish and next day caught one of 529 pounds (240 kg). [ 2 ]
In fact, tuna can maintain the temperature of their muscles at 5–20 °C (9–36 °F) above the temperature of surrounding water. [31] Overall, tuna do not have a set body temperature point; rather it maintains its T B within a narrow range, with variations of only 4–5 °C (7–9 °F) over time and from individual to individual.

Thunnus tonggol is a species of tuna of tropical Indo-West Pacific waters.. It is commonly known as the longtail tuna [1] or northern bluefin tuna. [4] [5] The usage of the latter name, mainly in Australia to distinguish it from the southern bluefin tuna, leads to easy confusion with Thunnus thynnus of the Atlantic and Thunnus orientalis of the North Pacific.
The Atlantic bluefin tuna is a close relative of one of the other two bluefin tuna species, the Pacific bluefin tuna. The southern bluefin tuna , on the other hand, is more closely related to other tuna species such as yellowfin tuna and bigeye tuna , and the similarities between the southern and northern species are due to convergent evolution.
Blue Fin Tuna.
