The owner of the Sushizanmai restaurant chain on Thursday, January 5, paid the biggest price for a single fish, dolling out over $600,000 for a Pacific bluefin tuna which was auctioned at Tokyo's famed Tsukiji fish market. For the sixth straight year, Kiyoshi Kimura, president of Kiyomura Corp., which owns the Sushizanmai chain, had the winning bid, paying 72 million yen ($614,000) for a 212 kilogram (467 pound) Pacific bluefin tuna -- a species experts warn is being overfished. That was well above last year's winning bid of 14 million yen, but half the record 155 million yen paid in 2013.
Afterward, Kimura posed with a sword-like knife in front of the big, dark-silvery fish, caught off the coast of northern Japan. Global appetite for sushi has driven numbers of the species to dangerously low levels. Scientific assessments completed in July showed that the number of Pacific bluefin has fallen to just 2.6 percent of its original estimated size.
