Giant bluefin tuna nets record-setting $500k at auction

The fish weighed in at 342 kg and was caught off the most northerly Japanese island of Hokkaido. The price far surpassed the previous record of Y20.3 million (£158,807) set in January 2001 for a 202-kg tuna.

The fish was reportedly purchased by a wholesaler and will be sold on to up-market sushi restaurants in Japan and Hong Kong at a price of Y95,000 (£743) per kilogramme.
