Tuna value dropping, industry must plan ahead: report

October 7, 2020 — Tuna is holding steady as a $40 billion-a-year business, but commercial fisheries worldwide are hauling in bigger catches of dwindling value, threatening the long-term survival of some species, according to a new report.

“Fisheries caught 500,000 more metric tons in 2018 than in 2012, but were paid $500 million less in dock value,” study co-author Grantly Galland, an officer with The Pew Charitable Trusts’ international fisheries group, told AFP.

Unless governments that regulate the industry through regional management bodies adopt long-term strategies, everything from supermarket tuna to $100-a-portion sashimi could wind up in short supply, the report warned.

Crashing populations of skipjack, bigeye, yellowfin and bluefin would also jeopardise livelihoods and disrupt ecosystems in which the top-level predators play a critical role.

WCPFC members agree to increase bigeye limits

December 11, 2017 — Members of the Western and Central Pacific Fisheries Commission concluded a five-day conference in Manilla, The Philippines, earlier this week by increasing catch limits on tropical tunas. It’s a move at least one conservation group fears could threaten the bigeye stock.

Beginning next year, Japan will be able to catch up to 18,265 metric tons of bigeye tuna. South Korea was allotted a nearly 14,000-metric-ton limit, while Taiwan will be able to harvest nearly 10,500 metric tons. China received a limit of more than 8,200 metric tons, in addition to a one-time transfer of 500 metric tons from Japan in 2018. Indonesia received a provisional allotment of nearly 5,900 metric tons, and the United States, which won the right to use its Pacific territories to increase its limit, can catch more than 3,500 metric tons.

Those limits were set after the commission’s scientific committee concluded that the bigeye stock “appears” not to suffer from overfishing.

Amanda Nickson, who is the director of international fisheries for The Pew Charitable Trusts, called the decision to increase the limits by 10 percent disappointing. The commission’s decisions mean the bigeye stock have a greater than 20 percent chance of falling below its accepted biomass standards over the next 30 years.

Sushi Alert: Grim Outlook for Bluefin Tuna

April 20, 2016 — TOKYO — The latest scientific assessment paints a likely bleak future for the Pacific bluefin tuna, a sushi lovers’ favorite whose population has dropped by more than 97 percent from its historic levels.

A draft summary of a report by the International Scientific Committee for Tuna and Tuna-like Species in the North Pacific Ocean seen by The Associated Press shows the current population of bluefin tuna is estimated at 2.6 percent of its “unfished” size. A previous assessment put the population at an already dire 4.2 percent.

Overfishing has continued despite calls to reduce catches to allow the species to recover. In some areas, bluefin tuna is harvested at triple the levels considered to be sustainable.

“The situation is really as bad as it appears,” said Amanda Nickson, director for Global Tuna Conservation at The Pew Charitable Trusts.

Limits imposed after the previous estimates actually allowed some countries to up their catches, she said.

How In Trouble Are Bluefin Tuna, Really? Controversial Study Makes Waves

March 9, 2016 — Bluefin tuna have been severely depleted by fishermen, and the fish have become a globally recognized poster child for the impacts of overfishing. Many chefs refuse to serve its rich, buttery flesh; many retailers no longer carry it; and consumers have become increasingly aware of the environmental costs associated with the bluefin fishery.

But a group of scientists is now making the case that Atlantic bluefin may be more resilient to fishing than commonly thought — and perhaps better able to rebound from the species’ depleted state. In a paper published Monday in the journal Proceedings of the National Academy of Sciences, the researchers suggest that fishery managers reassess the western Atlantic bluefin’s population, which could ultimately allow more of the fish to be caught.

The 10 co-authors, most of whom are scientists with the National Oceanic and Atmospheric Administration, say they’ve all but confirmed that bluefin tuna spawn in an area of the Atlantic Ocean previously suspected but not known to be a breeding ground. Not only that; the tuna spawning in this area off the Atlantic Coast are much younger and smaller than the age and size at which it was previously believed the fish become sexually mature, according to the scientists.

This, their paper claims, would make the western Atlantic bluefin tuna “less vulnerable to overexploitation and extinction than is currently estimated.”

But the study is controversial. Several tuna researchers we spoke with warned that the results are preliminary, and it’s much too soon to use them to guide how fisheries are managed
