The Most Expensive Tuna in the World
The most expensive tuna is $736000. A huge bluefin tuna fetched a record at the year’s first auction at Tokyo’s Tsukiji fish market. The record for the most expensive tuna fish was set by a single blue-fin tuna (Thunnus thynnus), weighing 342 kg (754 lb), which was sold at an auction in the Tsukji fish market in Tokyo, Japan, on 5 January 2011, where it raised 34.49 million Yen ($420,000).
The 269-kilogram tuna, the largest among the 274 shipped in from around the world, valued at 210,000 yen per kilogram, will be sold to Sushi Zanmai, a major sushi-restaurant chain in the country. The Most expensive tuna fish in the world was caught off Oma, in Aomori prefecture and just north of the tsunami-battered coast.
Tuna are a group of ocean fishes from the family Scombridae, particularly of the genus Thunnus. Tuna are fast swimmers, and some species are capable of speeds of 70 km/h (43 mph). Unlike most fish, which have white flesh, the muscle tissue of tuna ranges from pink to dark red. The red coloration derives from myoglobin, an oxygen-binding molecule, which tuna express in quantities far higher than most other fish. Some larger tuna species, such as bluefin tuna, display some warm-blooded adaptations, and can raise their body temperatures above water temperatures by means of muscular activity.
The winning bidder, Kiyoshi Kimura, president of Kiyomura Co., which operates the Sushi-Zanmai restaurant chain, said he wanted to give Japan a boost after last March’s devastating tsunami with this most expensive tuna.
