State of Tuna Stocks Worldwide Assessed in Comprehensive ISSF Report

Global tuna catch stays at 78% healthy level

March 8, 2018 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

Of the total tuna catch in 2016, 78% came from stocks at “healthy” levels, unchanged since last reported, according to a February 2018 International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. Skipjack tuna stocks — at healthy levels in all ocean regions — constituted more than one-half of the 2016 total catch.

One notable change in stock status in the February 2018 Status report is for Southern bluefin tuna, a stock that has moved from orange to yellow in abundance ratings. Stock abundance is low, about 13% of the unfished level. However, the stock is rebuilding continuously as a result of the implementation of a robust Management Procedure (a Harvest Strategy) by the Commission for the Conservation of Southern Bluefin Tuna, the regional organization in charge of managing the stock. In contrast, the Pacific bluefin stock, along with the Indian Ocean yellowfin stock and the Atlantic Ocean bigeye stock remain overfished. See Tables 1 and 2 in the report for specific rating changes.

There were no dramatic changes in tuna stock status since the previous November 2017 Status report; the updated report reflects new data made available at late 2017 tuna Regional Fisheries Management Organization (RFMO) meetings.

Updated several times per year, Status of the Stocks assigns color ratings (green, yellow or orange) on stock heath, stock management, and ecosystem impact. The report ranks the 23 stocks of major commercial tunas around the world using a consistent methodology.

Key Statistics in the Report

Total catch: In 2016, the total major commercial tuna catch was 4.9 million tonnes, a 2% increase from 2015. More than half of the total catch (57%) was skipjack tuna, followed by yellowfin (30%), bigeye (8%) and albacore (4%). Bluefin tunas (3 species) accounted for only 1% of the global catch. These percentages changed only slightly from the Nov. 2017 reporting period.
Abundance or “spawning biomass” levels: Globally, 57% of the 23 stocks are at a healthy level of abundance, 13% are overfished, and 30% are at an intermediate level.
Stocks receiving orange scores, indicating overfished status, include Atlantic Ocean bigeye, Pacific Ocean bluefin and Indian Ocean yellowfin.
Fishing mortality levels: 65% of the 23 stocks are experiencing a well-managed fishing mortality rate, and 13% are experiencing overfishing (with no change from the previous report).
Largest catches by stock: The three largest catches in tonnes are Western Pacific Ocean skipjack, Western Pacific Ocean yellowfin, and Indian Ocean skipjack.
Tuna production by ocean region: Most (53%) of the world’s tuna is harvested from the Western and Central Pacific Ocean, followed by the Indian Ocean (20%), Eastern Pacific Ocean (13%), and Atlantic Ocean (10%).
Tuna production by fishing gear: 65% of the catch is made by purse seining, followed by longline (12%), pole-and-line (8%), gillnets (3%) and miscellaneous gears (12%). These percentages changed only slightly from the Nov. 2017 reporting period.

About the Report

There are 23 stocks of major commercial tuna species worldwide – 6 albacore, 4 bigeye, 4 bluefin, 5 skipjack, and 4 yellowfin stocks. The Status of the Stocks summarizes the results of the most recent scientific assessments of these stocks, as well as the current management measures adopted by the RFMOs. This report ranks the status and management of the 23 stocks using a consistent methodology based on three factors: Abundance, Exploitation/Management (fishing mortality) and Environmental Impact (bycatch).

ISSF produces two reports annually that seek to provide clarity about where we stand — and how much more needs to be done — to ensure the long-term sustainability of tuna stocks: the Status of the Stocks provides a comprehensive analysis of tuna stocks by species, and the Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria (MSC) provides scores for the stocks and RFMOs based on MSC assessment criteria. The MSC-certified fisheries list (Appendix 2) in Status of the Stocks complements the Evaluation report.

Together, these tools help to define the continuous improvement achieved, as well as the areas and issues that require more attention. Access the newly updated ISSF stock status ratings here.

WCPFC committee, IATTC reach agreement to rebuild Pacific bluefin tuna population

September 5, 2017 — Representatives from countries that fish for Pacific bluefin tuna have reached an agreement on a long-term plan to restore the species’ population.

However, while conservationists applauded the pact, they said they now want to see the countries follow up their words with action.

The pact between members of the Western and Central Pacific Fisheries Commission’s Northern Committee and the Inter-American Tropical Tuna Commission was announced at the conclusion of the Northern Committee’s 13th Regular Session the morning of Friday, 1 September in Busan, South Korea. Details include:

Establishing a target goal of 20 percent of Pacific bluefin tuna’s historic population by 2034. Conservation officials said that would represent a seven-fold increase in the biomass over the next 17 years.
Maintaining catch quotas for the next seven years, and approving any increases in the limit only if there was a high probability it would not impact the targeted population goal.
Developing a plan by 2020 to reduce the amount of illegally caught Pacific bluefin tuna from entering the market.

The Northern Committee will recommend the WCPFC approve the measure at a meeting in December.

Tuna-fishing nations agree on plan to replenish severely depleted Pacific bluefin stocks

September 1, 2017 — TOKYO — The world’s Pacific bluefin tuna won something of a reprieve Friday, when tuna-fishing countries reached an agreement to gradually rebuild severely depleted stocks while still allowing nations such as Japan to catch and consume the delicacy.

Japan — by far the world’s biggest consumer of bluefin, eating about 80 percent of the global haul in the $42 billion tuna industry — had been resisting new rules, while conservationists have warned about the commercial extinction of bluefin in the Pacific Ocean.

Proponents of limits hailed the deal as a compromise that everyone could live with.

“It’s definitely a good first step towards the recovery of the species,” said James Gibbon, global tuna conservation officer at the Pew Charitable Trusts. “But it is only the first step. There are a lot of commitments that the countries agreed to, and we need to make sure they stick to them.”

At the week-long meeting in Busan, South Korea, the two bodies charged with shared management of Pacific bluefin — the northern committee of the Western and Central Pacific Fisheries Commission and the Inter-American Tropical Tuna Commission — hammered out a plan to try to put the fish back on a path to sustainability. Countries represented at the meeting included the United States, Canada, China, South Korea and Japan.

The Pacific bluefin population has been depleted by more than 97 percent from its historic high, because of overfishing.

Nonprofits ramp up campaign to increase protections for Pacific bluefin tuna

August 25, 2017 — Ahead of an international conference scheduled next week to discuss rebuilding the Pacific bluefin tuna population, several organizations and influential leaders have urged countries to act quickly to stop what they claim is a steep decline in the species’ numbers.

For years, the Monterey Bay Aquarium’s Seafood Watch initiative has urged people to avoid the fish because of its low numbers, but the campaign has picked up steam in advance of Western and Central Pacific Fisheries Commission’s Northern Committee 13th Regular Session in Busan, South Korea, scheduled to begin on Monday, 28 August. Those involved in the week-long talks centered on conservation measures for the Pacific bluefin tuna include the United States, Canada, Mexico, and Japan, with the latter country being the most dominant market for the species.

Among those speaking out included former U.S. Secretary of State John Kerry, who said the current situation not only threatens the ecology but the economy as well.

“Unsustainable fishing isn’t just the enemy of conservation, it’s the enemy of fishermen everywhere,” said Kerry in a statement on the aquarium’s blog. “We know we can do better. That is why we should all be invested in the difficult task of turning things around and getting Pacific bluefin tuna on a path to recovery.”

NOAA: Determination that bluefin aren’t ‘endangered’ unlikely to affect quota setting

August 15, 2017 — US regulators’ recent decision to reject a petition from environmental groups to list Pacific bluefin tuna as an endangered species is unlikely to affect quota levels, which are set by international bodies.

“I don’t envision this domestic Endangered Species Act determination directly implicating the international management of this species,” Chris Yates, the National Oceanic Atmospheric Administration (NOAA)’s west coast assistant regional administrator for protected resources said, in response to a question from Undercurrent News.

The US government doesn’t directly determine bluefin fishing rules in the Pacific, having ceded that authority by treaty to Inter-American Tropical Tuna Commission (IATTC), of which major bluefin catchers Japan, Mexico, South Korea and Taiwan are also members. The Western and Central Pacific Fisheries Commission (WCPFC) also manages bluefin stocks in those areas of the ocean.

IATTC, which is under strong pressure from environmental groups to conserve declining bluefin stocks, recently failed to agree to new measures at a meeting earlier this month in Mexico City. But members have agreed to revisit the issue at a future meeting in Busan, South Korea.

NOAA assessment

After a recent review of the stock, NOAA scientists struck a mostly positive tone about the stock’s prospects to recover.

Yates, and Matthew Craig, who recently chaired a NOAA review into the health of bluefin stocks, said that there are roughly 1.6 million individual bluefin in the North Pacific Ocean, with 140,000 bluefin being of reproductive age and size.

NOAA rejects bid to list tuna as endangered

August 9, 2017 — The Trump administration on Tuesday chose not to list the Pacific bluefin tuna as an endangered species, rejecting a petition by the largest global conservation group that the U.S. is a member of, with France, South Korea, Australia, and several other countries.

The Commerce Department’s National Marine Fisheries Service announced the decision after a 12-month review of the request that started under the Obama administration.

In response, environmentalists are organizing an international boycott of sushi restaurants, decrying what they say is the startling reversal of the agency’s original intent to list the tuna under the Obama administration.

The agency said that it looked at all factors affecting the bluefin tuna’s habitat, and based “on the best scientific and commercial data available … and after taking into account efforts being made to protect the species, we have determined that listing of the Pacific bluefin tuna is not warranted,” the agency said in a notice published in the Federal Register.

The International Union for Conservation of Nature had petitioned the U.S. government to list the tuna after assessing “the status of Pacific bluefin tuna and categorized the species as ‘vulnerable’ in 2014, meaning that the species was considered to be facing a high risk of extinction in the wild,” the notice read.

Tuna won’t be listed as endangered, Trump administration says

August 8, 2017 — Rejecting a petition from environmental groups, the Trump administration announced Monday that it will not list Pacific bluefin tuna — a torpedo-shaped fish that can grow to 1,000 pounds and which sells for $100,000 or more per fish in Japanese sushi markets — as endangered, despite that fact that the animal’s population has fallen 97 percent.

Even with heavy fishing pressure, the steely fish, which swim 6,000 miles between California and Asia, still number about 1.6 million, officials from NOAA, the National Oceanic and Atmospheric Administration, said Monday.

“The Pacific bluefin tuna does not meet the definition of threatened or endangered under the Endangered Species Act; that is, it’s not likely to become extinct either now or in the foreseeable future,” said Chris Yates, assistant regional administrator for protected resources at the NOAA Fisheries West Coast Region in Long Beach.

“The population has been at low levels before and has rebounded,” he added.

Environmental groups, however, were disappointed. They have compared bluefin tuna to elephant tusks or shark fins — products that come from an important, but vulnerable, species and command high prices for status value.
