"This morning at the famed Tsukiji Fish Market in Tokyo, the first auction of 2018 saw a massive bluefina tuna fetch a hefty $323,000. The fish weighed 890 pounds, Reuters reports, bringing its price per pound to nearly $800.
A company that operates several high-end sushi restaurants in Tokyo bought the giant fish and plans to turn it into 13,000 pieces of sushi, per the Financial Times. It’s the first time in seven years that the priciest fish at the New Year’s auction was sold to someone other than restaurateur Kiyoshi Kimura.
Paying more than $300,000 for one fish is certainly nothing to sneeze at, but it’s nowhere close to the highest price seen at Tsukiji’s New Year’s auctions: In 2013, Kimura bought a bluefin tuna for a record high price of $1.76 million — or more than $3,000 a pound."
