Tuna record hides big trouble for species
A bluefin tuna sold for a record US$3.1 million (NZ$4.6m) at the first auction of the year at Tokyo’s new fish market yesterday, but behind the celebrations hides a worrying tale of overfishing and dwindling stocks.
Kiyoshi Kimura, who owns the Sushi Zanmai restaurant chain, paid 333.6 million yen for the 278kg fish at the first auction of the year, and the first to be held at Tokyo’s new Toyosu fish market after last year’s the move from the famous Tsukiji market.
The price at the predawn auction was nearly 10 times higher than the price paid at last year’s auction – albeit for a considerably smaller fish – and roughly double the previous record, also set by Kimura, in 2013.
There was an intense bidding war with a rival buyer who had won last year.
The winner said he was ‘‘very satisfied with the quality’’ of the fish but admitted he had paid much more than he had expected.
‘‘The tuna looks so tasty and very fresh, but I think I did (pay) a little too much,’’ Kimura told reporters outside the market later, according to news agencies.
Kimura said a single piece of the tuna would be served to customers in his restaurants later that day.
The fish was caught off the coast of northern Japan’s Aomori prefecture by fishermen from the small town of Oma, which has a nationwide reputation for the quality of its tuna catch.
Bluefin tuna is highly valued for its taste in sushi restaurants, but decades of overfishing have sent stocks plummeting.
The IUCN Red List of Threatened Species classifies the Pacific Bluefin tuna, or Thunnus orientalis, as ‘‘vulnerable,’’ with a decreasing population.
‘‘The celebration surrounding the annual Pacific bluefin auction hides how deeply in trouble this species really is,’’ said Jamie Gibbon, associate manager of global tuna conservation at The Pew Charitable Trusts.
‘‘Its population has fallen to less than 3.5 per cent of its historic size and overfishing still continues today.’’
In response to the growing scarcity of the fish, Japan and other governments agreed in 2017 to strict quotas and restrictions on fishing, in an attempt to rebuild stocks from 20 per cent of historic levels by 2034.
Pacific Bluefin tuna reach a maximum length of nearly 3m and a maximum weight of 550kg. A top ocean predator, they have been described as ‘‘twice the size of a lion and faster than a gazelle.’’
