Albacore

Scientific Name: Thunnus Alalunga
Description
Albacore
is very low in sodium and is a very good source of protein,
vitamin A, vitamin B12, selenium, and niacin. For more on
nutrition, see Nutrition Facts.
Albacore
are widely distributed throughout the world's marine ecosystems
in tropical, sub-tropical, and temperate zones of the Pacific,
Atlantic, and Indian Oceans. In the Pacific Ocean, it is generally
believed that there exists two stocks of albacore, one in
the North Pacific hemisphere and one in the South Pacific
hemisphere. Available data indicate that the two stocks do
not cross the equator and have separate spawning grounds and
times.
Diet
Albacore
feed on fish, crustaceans, and squid.
Behaviour
Today's
albacore tuna are highly advanced marine teleosts, or bony
fish, whose earliest ancestors are generally believed to have
emerged during the Mesozoic Era, roughly 65 to 210 million
years ago. Albacore are members of the Scombridae family,
which includes 40 to 50 species of tuna and mackerel, 23 of
which are found, for at least a part of their life, in waters
off the coast of North America.

The maximum lifespan of albacore in the Atlantic is 13 years,
while it is only 9 years in the Mediterranean.

is a temperate tuna. Juveniles are mainly found in warmer
surface waters, while adults are found in cooler and deeper
waters.
