A single bluefin tuna has sold in Japan for 155m yen ($1.7m), almost triple the record price set last year.
High bids traditionally mark the year’s first auction at Tokyo’s Tsukiji fish market.
Even the buyer, sushi chain owner Kiyoshi Kimura, who also paid out the record price last year, said the cost was “a bit high”.
The sale came amid continued warnings from environmentalists that tuna stocks are dwindling and overfished.
This year’s record-breaking fish was caught off north-eastern Japan and weighed in at 222kg (489lbs), some 47kg lighter than last year’s prize-winner, which fetched 56m yen.
