Japan bluefin tuna fetches record $1.7m

Kiyoshi Kimura stumped up almost three times as
much as he did last year

A single bluefin tuna has sold in Japan for 155m yen ($1.7m; £1.05m), 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.
