New year, new bluefin tuna selling for an outrageously high price in Japan. A single 466-pound tuna was sold for $632,000 during the annual auction that kicks off the year at Tokyo’s Tsukiji fish market. The winning bidder was Kiyomura Corp. and Sushi Zanmai chain owner Kiyoshi Kimura, who bid a record-setting $1.76 million on a bluefin tuna in 2013. Bluefin continue to be a prized delicacy in Japan and at pricey sushi restaurants elsewhere despite years of warnings that it could go extinct due to relentless overfishing. Its population is now at just 2.6 percent of its historical average, but overfishing continues and in some areas the fish are being caught at three times the levels deemed sustainable.
