Tuna History
The word tuna dates back only to 1880 in print and is attributed as a Spanish American derivation of the English counterpart, tunny. It is derived from the LatinThunnus, the name of its scientific genus. Tuna has been fished from the warm, temperate parts of the Mediterranean Sea and the Pacific, Atlantic, and Indian Oceans since ancient times. As a member of the mackeral family, tuna naturally has a stronger, more robust flavor than whitefish. Tuna Facts

Tuna can cruise up to 55 miles per hour, and they are constantly in motion. To keep this speed machine going, the tuna eats up to ten percent of its body weight daily. Depending on the variety, weights average from 10 pounds up to 600 pounds per fish. The majority of the commercial tuna harvest comes from California. The average consumption of tuna in America is 3.6 pounds per person, per year, most of which is canned. One of the finest of all game and food fishes is the tuna, a giant relative of the mackerel. For beauty, strength, and speed, many sportsmen and commercial fishermen call the great bluefin tuna (Thunnus thynnus) the king of ocean game. It grows to a length of 14 feet (4 meters) and a weight of 1,800 pounds (800 kilograms). Its average weight varies from 60 to 200 pounds (25 to 90 kilograms) …http://kids.britannica.com/comptons/article-9277450/tuna/http://kids.britannica.com/comptons/article-9277450/tuna Tuna are large fish that live in most parts of the world's oceans.

A tuna is a saltwater finfish that belongs to the tribe Thunnini, a sub-grouping of themackerel family (Scombridae) – which together with the tunas, also includes the bonitos,mackerels, and Spanish mackerels. Thunnini comprises fifteen species across fivegenera,[1] the sizes of which vary greatly, ranging from the bullet tuna (max. length: 50 cm (1.6 ft), weight: 1.8 kg (4 lb)) up to the Atlantic bluefin tuna (max. length: 4.6 m (15 ft), weight: 684 kg (1,508 lb)). The bluefin averages 2 m (6.6 ft), and is believed to live for up to 50 years. Their circulatory and respiratory systems are unique among fish, enabling them to maintain a body temperature higher than the surrounding water. An active and agile predator, the tuna has a sleek, streamlined body, and is among the fastest-swimmingpelagic fish – the yellowfin tuna, for example, is capable of speeds of up to 75 km/h (47 mph).[2] Found in warm seas, it is extensively fished commercially and is popular as a game fish. As a result of over-fishing, stocks of some tuna species, such as the Southern bluefin tuna, have been reduced dangerously close to the point of extinction.[3] This article is
