Updated ISSF Status of the Stocks Report Shows Tuna Stock Abundance and Fishing Mortality Improvements

November 2, 2017 — WASHINGTON — The following was released  by the International Seafood Sustainability Foundation:

Of the total tuna catch, 78% comes from stocks at “healthy” levels, an increase of 2% since last reported, according to a November 2017 International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. Eleven percent of the global catch came from overfished stocks, and another 11% of the catch is from stocks at an intermediate level of abundance. (See “Key Questions” below for definitions of overfished and overfishing.)

Updated several times per year, Status of the Stocks ranks the 23 stocks of major commercial tunas around the world using a consistent methodology. The report assigns color ratings (green, yellow or orange) on stock health, alternately noted as “abundance” and “spawning biomass”; fishing mortality; and ecosystem impact.

There are some encouraging changes in tuna stock status since the previous February 2017 Status report. The November 2017 report reflects new data from 2017 tuna Regional Fisheries Management Organization (RFMO) meetings:

  • Abundance ratings improved for Eastern Pacific bigeye, Western and Central Pacific bigeye, Mediterranean albacore, and Western Atlantic bluefin.
  • Fishing mortality ratings improved for Western and Central Pacific bigeye, North Pacific albacore, and Indian Ocean albacore.

In contrast, two bluefin stocks (Southern and Pacific Ocean), one yellowfin stock (Indian Ocean), and one bigeye stock (Atlantic Ocean) remain overfished. See Tables 1 and 2 in the report for specific rating changes.

Inadequate bycatch monitoring and/or bycatch mitigation measures — represented by separate “Environmental Impact” scores, the third rating area — still are a concern in many of the tuna fisheries studied.


Key Findings in Updated Report
Other notable statistics and findings include:

  • Total catch: In 2015, the total major commercial tuna catch was 4.8 million tonnes, a 4% decrease from 2014. More than half of the total catch (58%) was skipjack tuna, followed by yellowfin (28%), bigeye (8%) and albacore (4%). Bluefin tunas accounted for only 1% of the global catch. These percentages did not change from the February 2017 report.
  • Abundance or “spawning biomass” levels: Globally, 57% of the 23 stocks are at a healthy level of abundance (an increase of 5% from the previous report), 17% are overfished, and 26% are at an intermediate level.
    • Stocks receiving orange scores, indicating overfishing or overfished status, include both Southern Hemisphere and Pacific Ocean bluefin, Indian Ocean yellowfin, and Atlantic bigeye.
  • Fishing mortality levels: 65% of the stocks (an 8% improvement since the previous report) are experiencing a low fishing mortality rate, and 13% are experiencing overfishing.
  • Largest catches by stock: The three largest catches in tonnes are Western Pacific Ocean skipjack, Western Pacific Ocean yellowfin, and Indian Ocean yellowfin.
  • Tuna production by fishing gear: 64% of the catch is made by purse seining, followed by longline (12%), pole-and-line (9%), gillnets (4%) and miscellaneous gears (11%).

For the first time in Status of the Stocks history, the November 2017 report features an appendix with a list of fisheries certified by the Marine Stewardship Council (MSC).

“The MSC fishery certification scheme is the most widely recognized indicator of seafood sustainability,” explains Dr. Victor Restrepo, Vice President of Science, ISSF. “The list helps us to track the tuna stocks and fishing gears that are certified.”

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. In addition, 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 provides a review of the health of tuna fisheries by region. 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.

Key Questions Answered by the Report
Status of the Stocks answers three key questions about each tuna stock:

  1. Is the stock overfished?
    A. The report measures the abundance of fish that are able to reproduce each year, called the spawning stock biomass (SSB), and compares it to an estimate of the biomass that would produce maximum sustainable yield (SSBMSY), which is the spawning biomass that results in the highest average catches in the long-term (this is a target of fisheries management). When SSB is below SSBMSY the stock is in an “overfished” state.

Overfishing doesn’t necessarily mean that the stock is in immediate danger of extinction or collapse — it means that currently, the fish aren’t being allowed to grow and reproduce at their most productive level. If a stock is overfished, the report will note any corrective measures being taken by the relevant fisheries management organization (RFMO).

  1. Is it in danger of becoming overfished?
  2. The report measures the fishing mortality rate (F), a measure of fishing intensity, and compares it to the fishing mortality that produces maximum sustainable yield (FMSY). When F is above FMSY, the stock is in danger of becoming overfished in the future. This is called overfishing. If overfishing is taking place, the report will note any corrective measures being taken.
  3. Are the methods used to catch the tuna also catching significant numbers of non-targeted species?
  4. The report also measures the environmental impact of fishing in terms of “bycatch” rates. Bycatch is any species caught by the boat that is not the kind of fish the skipper is searching for. All fishing methods result in some bycatch of non-target species. The report identifies the relative bycatch rates by fishing gear and reports on mitigation measures adopted by the RFMOs for various species groups.

Tuna lab leaving Gloucester, Mass.

Lutcavage, colleagues to work out of UMass Boston

October 6, 2017 — For the first time in almost seven years, the highly-regarded Large Pelagics Research Center affiliated with the University of Massachusetts no longer has a Gloucester address.

The center, which has performed groundbreaking and internationally acclaimed research on the spawning habits and habitats of Atlantic bluefin tuna, closed up shop Thursday at its most recent home — the Americold-owned building at 159 E. Main St. in East Gloucester.

Americold has been actively shopping the site for months and recently informed the center it would have to vacate its office space by the end of October. Molly Lutcavage, the founder and executive director of the center, and Tim Lam, an assistant research professor, didn’t bother waiting until the end of the month.

“It’s sad to think that we won’t have a Gloucester presence anymore,” Lutcavage said. “For now, I guess we’ll be working out of our houses and garages.”

The center has been forced to navigate some rough seas in the past few years, changing its affiliation within the University of Massachusetts system and being forced out of its original facility at Hodgkins Cove, where it had been housed since 2011.

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.”

It’s Not Okay To Sell Tuna Under The Radar Or Without A Permit

August 24, 2017 — The following is excerpted from an article published Tuesday by Fissues.org, a project of the Marine Fish Conservation Network:

As we get into the thick of tuna season right now, and plenty of “large-medium” and “giant” class bluefin tuna are being caught by anglers around Cape Cod, and “small mediums” as well as good-sized yellowfin in the New York Bight, I thought it more than appropriate to say this…

It’s not okay….

It’s not okay for an angler to take his or her bluefin, or yellowfin, or bigeye or any fish for that matter and sell it to the local restaurant through the back door… for freak’n gas money. Unfortunately, this kinda thing happens pretty regularly up here. Don’t tell me that it doesn’t, because I hear the bragging frequently.

And don’t tell me that it’s a victimless crime. The hard-working full-time commercial fishermen are the first to get screwed. But it’s the consumer as well, who ends up eating a fish that hasn’t been properly cared for without knowing the risks (in the case of tuna, it needs to be flash frozen so as to get rid of parasites). And the fish? Well, none of that backdoor stuff gets reported so we have no idea the scale of such removals… And that affects how these fish are managed and ultimately the long-term sustainability of the stock.

Let’s be crystal clear about one thing. You cannot legally sell tuna to anyone but a federally permitted HMS (Highly Migratory Species) dealer and you aren’t supposed to do so without the proper federal permits and state landing permits.

Under no circumstances are those backdoor sales legal.

But really, that’s not the main reason I felt compelled to write this.

What’s starting to become a big problem is the HMS “Charter/Headboat” permit, which inexplicably allows anyone with such permit running a charter to sell their bluefin, as long as they are of commercial size (73”-plus).

So here’s the deal… If I understand the intent of the permit correctly – and I’ve discussed with NOAA HMS, so I think I do – you can’t run both a commercial and charter fishing trip at the same time. Directly from HMS Permit FAQs site: “This permit allows a vessel to fish both commercially for tunas and recreationally for HMS, although not on the same day.”

How Ocean Aquaculture Could Feed the Entire World – and Save Wild Fish

Marine researchers at the University of California, Santa Barbara, mapped out the potential of the open ocean to support farmed fish and came to some surprising conclusions.

August 21, 2017 — About five out of every six fisheries worldwide has reached or passed the limit of what it can sustainably produce, according to the World Wildlife Fund. Drought, dams, agricultural runoff and other pressures have depleted wild salmon populations in the Eastern Pacific, while on the east coast of North America, wild Atlantic salmon exists mainly in the memories of the Greatest Generation. Bluefin tuna, the preferred delicacy of the world’s finest sushi chefs, is at 2.7 percent of its historical population – about the same as the Bengal tiger.

Meanwhile, seafood farmed in coastal regions has been infected with sea lice, pollutes neighboring ecosystems with waste, sometimes produces fewer nutrients than are fed into the system, often destroys carbon-sequestering mangroves and can require large amounts of antibiotics to stave off disease.

But according to a new study from the University of California, Santa Barbara’s Bren School of Environmental Science and Management, aquaculture could feed a global population expected to grow to nearly 10 billion by 2050. Lead author Rebecca Gentry, a newly minted PhD in marine ecology, and her colleagues wrote that the open ocean “is largely untapped as a farming resource,” representing “an immense opportunity for food production.” In the study published August 14 in the journal Nature Ecology & Evolution, they found that the entire world’s current output of wild-caught seafood could be farmed in areas that in total would comprise just 0.015 percent of the ocean’s surface area, if grouped together in a way that the authors note would not be realistic or recommended. That’s the equivalent to the size of Lake Michigan.

“People assume the oceans are big but no one had quantified it,” Gentry said. “There’s not that much broad-scale ecological research on marine aquaculture, so we needed a base of information to get an idea of where we can do it.”

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.

UMaine to Receive More Than $220K From NOAA to Study Tuna

August 11, 2017 — ORONO, Maine — The University of Maine is slated to receive more than $220,000 from the federal government to support research of Atlantic bluefin tuna.

Republican Sen. Susan Collins and independent Sen. Angus King say the money from the National Oceanic and Atmospheric Administration will help with UMaine’s research about the tuna’s age, growth and population in the northwest Atlantic Ocean.

UMaine researchers will work with dealers, fishermen and other stakeholders from Maine to North Carolina on the work.

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.
