ISSF Report: 16 Tuna Stocks Not Meeting Criteria for Marine Stewardship Council (MSC) Sustainability Standard

February 25, 2021 — The following was released by the International Seafood Sustainability Foundation:

Independent fisheries scientists in ISSF 2021-01: An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria — a February 2021 report commissioned by the International Seafood Sustainability Foundation (ISSF) — found that seven out of 23 major commercial tuna stocks worldwide are successfully avoiding overfishing when measured against the Marine Stewardship Council (MSC) Fisheries Standard and maintaining target stock biomass levels: North Atlantic albacore, South Atlantic albacore, Eastern Atlantic bluefin, Western Pacific skipjack, Eastern Pacific yellowfin, South Pacific albacore and Indian Ocean skipjack. These seven stocks earned a passing score (two of them without conditions) for the MSC Fisheries Standard on its Principle 1: “Sustainable Fish Stocks.” Under Principle 3: “Effective Management,” most tuna regional fisheries management organizations (RFMOs) scored well.

MSC is an independent, international, non-profit organization that oversees a program to assess global wild-capture fisheries and certify them as “sustainable” if they meet its Fisheries Standard criteria. In the March 2020 edition of the report, four stocks passed Principle 1, indicating a slight improvement explained by the new stock assessments conducted in 2020, as well as the good scores of one of the bluefin stocks newly incorporated in this version. Principle 3 evaluations remained unchanged for the most part.

The report attributes 16 other tuna stocks’ inability to pass MSC Principle 1 to poor stock status, the lack of well-defined harvest control rules (HCRs), and/or the lack of effective tools to control harvest. A stock will pass if its overall score is 80 or above, and no single score is less than 60.

Notable Report Findings

An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria was independently authored by Paul A. H. Medley, Jo Gascoigne, and Giuseppe Scarcella. This is the first time the report evaluates the four bluefin stocks (Western Atlantic bluefin, Eastern Atlantic and Mediterranean bluefin, Pacific bluefin and Southern bluefin) under Principle 1 and the Commission for the Conservation of Southern Bluefin Tuna (CCSBT) under Principle 3. One of the four bluefin stocks (Eastern Atlantic) received a P1 overall passing score.

Most changes in the evaluation of other tuna stocks are due to new tuna stock assessments conducted by RFMOs in 2020 and how those stock assessments affect HCRs (e.g., providing evidence that management controls are effective in limiting fishing mortality).

About the Report

An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria takes a consistent, comprehensive approach to scoring tuna stocks based on certain components of the MSC standard. The report — updated regularly since it was first published in 2013, and organized by individual tuna stock and tuna RFMO — is designed to:

  • Provide a basis for comparing between stock scores and tuna RFMO scores as assessed by the same experts
  • Become a useful source document for future tuna certifications or in the establishment of tuna Fishery Improvement Projects (FIPs)
  • Prioritize ISSF projects and advocacy efforts against initiatives that will improve low performance indicator scores

The scores in the report focus on stock status (MSC Principle 1) and the international management aspects relevant to RFMOs (part of MSC Principle 3) and are based on publicly available fishery and RFMO data. Each of these Principles is evaluated in relationship to Performance Indicators (PIs) within each Principle. The Evaluation report also includes detailed remarks on each stock, evaluations of the five RFMOs, and comprehensive reference citations.

MSC Principle 1

The MSC Principle 1 states: “A fishery must be conducted in a manner that does not lead to overfishing or depletion of the exploited populations and, for those populations that are depleted, the fishery must be conducted in a manner that demonstrably leads to their recovery.”

Of the 23 tropical and temperate tuna stocks, 7 achieved a passing score for Principle 1, meaning its overall score is 80 or above, and no single score is less than 60. Failure was due to poor status of the stock, the lack of well-defined harvest control rules in place and/or the lack of effective tools to control harvest. Three of the 23 stocks have fully implemented well-defined harvest control rules, and there has been progress towards this aim by all RFMOs.  However, with the exception of CCSBT, not all RFMOs have made progress toward this aim for all tuna stocks under their management. Slow progress — exacerbated in some cases by the Covid-19 pandemic — and failure to implement controls before rebuilding is required leads to a stock’s failing to meet minimum requirements on harvest control rules.

Regarding stocks receiving passing scores:

  • Among nine tuna stocks in the Atlantic Ocean, three received an overall principle-level passing score: Northern albacore, Southern albacore and Eastern bluefin (the only bluefin stock to receive a passing score).
  • Among nine tuna stocks in the Pacific Ocean, three received overall principle-level passing scores: Western skipjack, Southern albacore and Eastern yellowfin.
  • Among five stocks in the Indian Ocean, one received an overall principle-level passing score: skipjack.

Regarding stocks receiving failing scores:

  • In the Atlantic, yellowfin, bigeye, Western skipjack, Eastern skipjack, Western bluefin and Mediterranean albacore all received principle-level failing scores.
  • In the Pacific, six stocks received overall principle-level failing scores: Western yellowfin, Western bigeye, Eastern bigeye, Eastern skipjack, Northern albacore and Pacific bluefin.
  • In the Indian Ocean, yellowfin, bigeye and albacore all received overall principle-level failing scores.
  • Southern bluefin tuna also received an overall P1 failing score.

MSC Principle 3

The MSC Principle 3 states: “The fishery is subject to an effective management system that respects local, national and international laws and standards and incorporates institutional and operational frameworks that require use of the resource to be responsible and sustainable.”

One tuna RFMO — the Inter-American Tropical Tuna Commission (IATTC) — received unconditional passing scores for all seven performance indicators under Principle 3. This is the first year that the CCSBT was included in the analysis, and that RFMO did not receive an unconditional passing score. The other four tuna RFMOs received overall principle-level passing scores from the authors.

While the report focuses on tuna stock status and sustainability as well as on RFMO policies, it does not address national or bilateral management systems, gear- or fleet-specific ecosystem impacts, or specific fisheries’ ecosystems — all of which are also considered within the MSC assessment methodology.

Since 2011, ISSF has been an active stakeholder in MSC tuna fishery assessments and certifications. ISSF’s strategic objective is to develop and implement verifiable, science-based practices, commitments and international management measures to help all tuna fisheries become capable of meeting the MSC certification standard without conditions.

NGOs critical of ICCAT rollover of Western Atlantic bluefin quota

January 28, 2021 — The International Commission for the Conservation of Atlantic Tunas (ICCAT) has approved a rollover of 2020’s total allowable catch (TAC) for western Atlantic bluefin tuna.

In response, non-governmental organizations including The Pew Charitable Trusts have warned the move will likely lead to overfishing of the stock.

Tuna goes for $200,000 at Tokyo market’s New Year auction

January 5, 2021 — A bluefin tuna sold for 20.8 million yen ($202,197) in the first auction of the new year at Tokyo’s Toyosu fish market on Tuesday when it reopened after the holiday break.

This was sharply down from the 193 million yen the highest-selling tuna fetched at last year’s first Toyosu auction.

One major bidder, Kiyomura Corp, said they had refrained from bidding high this year out of fear that a large number of customers would be inspired to flock to their restaurants since high bids for high quality tuna usually attract media attention.

The government has said eating and drinking out is one of the major causes of coronavirus infections.

Selling prices in the first tuna auction fluctuate widely from year to year in Japan, with a record 333.6 million yen paid in 2019.

Fresh COVID restrictions bode ill for tuna wholesalers, but online sales offer hope

December 29, 2020 — Seafood wholesalers at the Toyosu Wholesale Market in Tokyo, Japan, can expect lower restaurant demand at the holidays due to fresh COVID-19 restrictions, but some have teamed up with online marketers to sell high-end items like bluefin tuna and snow crab directly to consumers.

Restaurants and bars were asked on 14 December to close by 10 p.m. by the governors of Tokyo, Osaka, Aichi, Saitama, Kanagawa, and Okinawa prefectures. In Gifu Prefecture, shops that serve alcohol were asked to close at 9 p.m. Most of the closures only apply over the busy New Year holiday period, when many people traditionally visit their hometowns and meet friends and family.

NORTH CAROLINA: Bluefin tuna season off to a good start in Carteret County

December 14, 2020 — As winter weather sets in, the season for Atlantic bluefin tuna has arrived along the North Carolina coast, and the early season has been good so far for at least two Carteret County charter businesses.

Bluefin tuna are a commercially valuable and highly sought-after fish, with individual fish selling for thousands of dollars on the international market. The fish are managed by the International Commission for the Conservation of Atlantic Tunas in two stocks, the eastern stock and the western stock, though the two often intermingle. In the U.S., according to the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service, the baseline annual quota for bluefin tuna is 1,247.86 metric tons; this quota is further divided into sub quotas based on types of gear. The general category, which covers commercial handgear, has a sub quota of 555.7 metric tons.

Bluefin tuna traditionally show up on the North Carolina coast in December through early winter, and according Fish Whistle Fishing Charters of Morehead City’s Capt. Mike Ajamian, as of Tuesday he’s caught four.

87% of Global Tuna Catch Comes from Stocks at Healthy Levels, While 10% Require Stronger Management

December 10, 2020 — The following was released by the International Seafood Sustainability Foundation:

Of the total commercial tuna catch worldwide, 87% came from stocks at “healthy” levels of abundance, according to the newest International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. In addition, 10% of the total tuna catch came from overfished stocks and 3% from stocks at an intermediate level of abundance. The previous version of this report was published by ISSF in March 2020. This updated report reflects results of tuna RFMO meetings through October 2020, and the next version will include results of RFMO meetings that have taken place more recently or are taking place now.

Several tuna stocks worldwide are considered overfished and/or subject to overfishing:

  • The Atlantic Ocean bigeye, Indian Ocean yellowfin and Pacific bluefin tuna stocks are currently overfished and subject to overfishing.
  • Indian Ocean albacore and bigeye are subject to overfishing.
  • All skipjack and most albacore stocks are healthy.

Ratings for the following species have changed since last reported in March: 

  • The abundance rating for Eastern Pacific Ocean bigeye has been downgraded from green to yellow, but the fishing mortality rating of that stock has improved from orange to yellow.
  • Both the fishing mortality rate ratio and abundance rating for Eastern Pacific Ocean yellowfin have improved from orange to green. This was primarily due to changes in the stock assessment methodology used.

ISSF publishes its signature Status of the Stocks report twice each year using the most current scientific data on 23 major commercial tuna stocks.

Key Statistics in the Report

  • Abundance or “spawning biomass” levels: Globally, 65% of the 23 stocks are at healthy levels of abundance, 13% are overfished and 22% are at an intermediate level.
  • Fishing mortality levels: 74% of the 23 stocks are experiencing a well-managed fishing mortality rate, and 22% are experiencing overfishing.
  • Total catch: The catch of major commercial tuna stocks was 5.2 million tonnes in 2018, an 8% increase from 2017. 58% was skipjack tuna, followed by yellowfin (29%), bigeye (8%) and albacore (4%). Bluefin tunas accounted for 1% of the global catch.
  • Largest tuna catches by stock: The five largest catches in tonnes, unchanged since the previous report, are Western Pacific Ocean skipjack, Western Pacific Ocean yellowfin, Indian Ocean skipjack, Indian Ocean yellowfin and Eastern Pacific Ocean skipjack.
  • Tuna production by fishing gear: 65% of the catch is made by purse seining, followed by longline (10%), pole-and-line (8%), gillnets (4%) and miscellaneous gears (13%).  These percentages changed minimally since the previous report.

The Status of the Stocks report is reviewed by the ISSF Scientific Advisory Committee, which provides advice on its content. The report does not advocate any particular seafood purchase decisions.

The Pandemic’s Impact on the Status of the Stocks  

This is the first update to this report since March 2020, when the COVID-19 pandemic started to impact the work of the RFMOs. In particular, meetings of the scientific committees and commissions have been scheduled on different dates than usual, and this has delayed this update.

Furthermore, readers should be aware that RFMOs issued exemptions to certain monitoring requirements such as observer coverage. As such, the summaries of management measures provided for the stocks, particularly in relation to observer coverage, may not be completely accurate in reflecting the monitoring that is ongoing during this exceptional 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. Updated twice per year, Status of the Stocks assigns color ratings (green, yellow or orange) using a consistent methodology based on three factors: Abundance, Exploitation/Management (fishing mortality) and Environmental Impact (bycatch).

ISSF produces two Status of the Stocks reports annually 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 presents a comprehensive analysis of tuna stocks by species, and the Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council (MSC) Criteria 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.

In addition, ISSF maintains a data-visualization tool based on its Status of the Stocks report. The “Interactive Stock Status Tool” is located on the ISSF website and accessible through the Status of the Stocks overview page; users can easily toggle through tuna abundance and exploitation health indicators by catch or stock and filter by location and species as well as be informed about the share of total catch by species/stocks and gear types.

Bluefin Tuna in Focus as Japan Seeks Boost to Catch Limits

October 21, 2020 — Countries involved in managing bluefin tuna fisheries are set to face-off over a Japanese proposal to raise its catch quotas for the fish, highly prized for sushi and sashimi.

At an online meeting that began Tuesday, Japan is seeking to raise its catch limits for both smaller and larger bluefin tuna by 20%.

A slight improvement in the spawning population for the fish has raised confidence that it can recover from decades of overfishing. But conservation experts worry that the capture of small fish used for farming bluefin tuna is may be putting the recovery of the species in peril.

The Western and Central Pacific Fisheries Commission includes more than two dozen countries that collaborate to manage fisheries on the high seas and curb illegal and unauthorized fishing and other activities that endanger highly migratory species such as the Pacific bluefin.

International Panel Omits Pacific Bluefin Tuna Quota Hike Again

October 13, 2020 — An international panel failed to adopt a Japan-proposed plan to increase catch quotas for Pacific bluefin tuna at an online conference on Thursday, in the same outcome as last year’s meeting, Japan’s Fisheries Agency said.

The Northern Committee of the Western and Central Pacific Fisheries Commission reached the decision, as the United States argued that tuna stocks continue to be scarce in the Pacific and objected to the proposal. At the committee, approval from all members is required for a proposal to be passed.

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.
