Atlantic Bluefin Tuna
The Atlantic bluefin tuna is one of the largest and fastest of all the world’s fishes. This particular species of tuna is capable of reaching 990 pounds but the average weight is 550 pounds. The average size of a bluefin tuna is 6.5 feet long. The color of the Atlantic bluefin tuna is dark blue above and gray below with a gold coruscation covering the body and has bright yellow finlets.
Atlantic bluefins are warm blooded, a rare trait for fish and they are comfortable in the cold waters of Newfoundland and Iceland. Atlantic bluefins once swam in the Black Sea but have since become extinct in that particular body of water.
In the 1970s, demand for the Atlantic bluefin soared, particularly in Japan. In January 2012, a prime 523 pound tuna was sold in a Japanese market for a whopping $736,000, a world record. Despite repeated warnings, overfishing continues to decline this species’ population. Since the 1930s, the bluefin tuna has been one of the most important big-games species sought after by fishermen. With less numbers than the polar bear, the Atlantic bluefin tuna is listed as endangered.
