ISSF Report: 12 Tuna Stocks Not Meeting Criteria for Marine Stewardship Council (MSC) Fisheries Standard

Fisheries scientists in An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria — a June 2024 report commissioned by the International Seafood Sustainability Foundation (ISSF) — found 11 of the 23 major commercial tuna stocks worldwide are successfully avoiding overfishing and maintaining target stock biomass levels when measured against the Marine Stewardship Council (MSC) Fisheries Standard. In the March 2023 edition of the ISSF report, eight stocks passed Principle 1. In this year’s report, three additional stocks received a passing score.

The 11 stocks are Western Atlantic skipjack, North Atlantic albacore, South Atlantic albacore, Eastern Atlantic bluefin, Western Pacific yellowfin, Western Pacific bigeye, Western Pacific skipjack, Eastern Pacific yellowfin, Eastern Pacific skipjack, Indian Ocean skipjack and Southern Ocean bluefin. These stocks achieved a passing score for the Standard’s Principle 1, “Sustainable Fish Stocks,” which requires fisheries to be managed in a manner that does not lead to overfishing or depletion of exploited fish populations.

Seven of the 23 stocks also have fully implemented well-defined harvest control rules. However, failure to implement controls before rebuilding is required continues to contribute to an increasing number of stocks failing to meet minimum requirements on harvest control rules.

An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria was authored by Paul A. H. Medley and Jo Gascoigne.

About the MSC Fisheries Standard

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.

About the Report

ISSF 2024-06: 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. Updated regularly since it was first published in 2013, and organized by individual tuna stock and tuna Regional Fisheries Management Organization (RFMO), the report is designed to:

  • Provide a basis for comparing between stocks scores that are assigned by the same experts
  • Become a useful source document for future tuna certifications
  • Give a “snapshot” of the current status of the stocks and the strengths and weaknesses of RFMOs

The updated scores in the report focus on stock status (MSC Principle 1) and are based on publicly available fishery data. MSC Principle 1 is evaluated in relationship to its Performance Indicators (PIs). The report is adapted to MSC standard 2.01 — released in 2019 — and to changing stock status and management situations. As the MSC has delayed implementation of MSC Standard 3.0, ISSF will adjust the report to measure against the new standard when appropriate in the future. In addition, this update does not re-score the RFMO section (Principle 3).

The Evaluation report 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 over-fishing 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.” The report authors attribute stocks with failing scores to poor stock status, the lack of well-defined harvest control rules in place and the lack of effective tools to control harvest. In the 2024 report, seven of the 23 stocks have fully implemented well-defined harvest control rules.

Notes regarding tuna stocks receiving passing scores:

  • Unchanged since last year’s March 2023 version of the report, of nine tuna stocks in the Atlantic Ocean, four received an overall principle-level passing score: Western skipjack, Northern albacore, Southern albacore and Eastern bluefin.
  • Among nine tuna stocks in the Pacific Ocean, these five received overall principle-level passing scores: Western yellowfin, Western bigeye, Western skipjack, Eastern yellowfin and Eastern skipjack. Western yellowfin and Western bigeye did not receive a principle-level passing score in the March 2023 report.
  • Among four tuna stocks in the Indian Ocean, as in last year’s report, only skipjack received an overall principle-level passing score.
  • Southern bluefin received an overall principle-level passing score — a change from last year’s report. This stock is also the second bluefin stock to receive a passing score.

Notes regarding tuna stocks receiving failing scores:

  • In the Atlantic, yellowfin, bigeye, Eastern skipjack, Mediterranean albacore and Western bluefin received principle-level failing scores — as also reported last year.
  • In the Pacific, four stocks — as also reported last year — received overall principle-level failing scores: Eastern bigeye, Northern albacore, Southern albacore and Pacific bluefin.
  • In the Indian Ocean, as reported last year, yellowfin, bigeye and albacore all received overall principle-level failing scores.

An updated infographic featuring average scores based on MSC Principle 1 since 2013 is available for download on ISSF’s website. Additionally, a related infographic featuring average scores for each tuna RFMO based on Principle 3 is available.

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 and maintaining the MSC certification standard.

ISSF Publishes 2023 Annual Report Highlighting Collaborative Progress Toward More Sustainable Tuna Fisheries

The International Seafood Sustainability Foundation (ISSF) released its 2023 annual report today, titled Navigating Toward Sustainable Tuna Fisheries, which presents the organization’s accomplishments on the path to more sustainable tuna fisheries — especially through collaboration with tuna vessels, fishers and other partners in the seafood industry.

“Skilled, conscientious fishers in all oceans take proactive steps every day to protect marine life — avoiding overfishing, reducing bycatch and providing data for scientific and compliance reporting — while harvesting their catch. As one indicator of the strides they have made, more than 65 tuna fisheries are certified by the Marine Stewardship Council as meeting its criteria,” Susan Jackson, ISSF President, remarks in the report. “We are grateful to ISSF’s many vessel partners in sustainable fishing — and we celebrate our multi-faceted collaborations with fishers at sea and on shore.”

Navigating Toward Sustainable Tuna Fisheries reviews ISSF’s continued marine research and advocacy efforts to identify and promote best practices in tuna and ocean conservation with fishers, vessels, tuna companies and Regional Fisheries Management Organizations (RFMOs). The report also covers ISSF’s activities with peer environmental nongovernmental organizations (NGOs) and scientific agencies and highlights work to promote verified accountability in sustainability commitments made throughout the tuna supply chain.

Jackson continued, “Since our founding, ISSF has prioritized — and prized — working closely with fishers, vessel owners and the organizations that represent them to better understand their sustainable-fishing challenges, successes and techniques. Nearly two decades later, we are still enthusiastically listening, learning and contributing resources and support.”

Navigating Toward Sustainable Tuna Fisheries Highlights

ISSF’s 2023 annual report includes a feature article on the importance of ISSF’s Vessels in Other Sustainability Initiatives (VOSI) list and other efforts to make electronic monitoring (EM) adoption in all tuna fisheries — regardless of vessel type or ocean region — a reality. Ben Gilmer, Chair of ISSF Environmental Stakeholder Committee and Director of Large-Scale Fisheries, The Nature Conservancy, authors “Tools for Transparency.”

The report also outlines ISSF’s critical science-focused and verification-related efforts with industry partners, including seafood companies and tuna fishing vessels. ISSF accomplishments in 2023 include:

  • 35 coordinated research projects on ecosystem impacts, tuna stock health and combatting Illegal, Unreported and Unregulated (IUU) fishing activities — demonstrating ISSF’s scope of research and impact
  • Information exchange and problem-solving between fishers and scientists through 25 in-person purse seine skippers’ workshops with 480+ participants. Also, 1,575 fishers completed ISSF’s Skippers’ Guidebooks to Sustainable Fishing Practices.
  • Reaching 1,500+ registrations on the ProActive Vessel Register (PVR) — one of four public vessel lists ISSF provides to foster transparency in tuna fishing. Also, ISSF has more than doubled registrations on its VOSI public vessel list for seafood sourcing to nearly 500 since the list’s October 2020 inception.
  • Engagement with 100% of active tuna purse seine fisheries improvement projects (FIPs) and 75% of longline FIPs.

Downloadable infographics and links to related reports and interactive content on the ISSF website are also available throughout the Navigating Toward Sustainable Tuna Fisheries PDF.

ISSF Annual Conservation Measures & ProActive Vessel Register Compliance Report

Navigating Toward Sustainable Tuna Fisheries are findings from the complementary ISSF Annual Conservation Measures & ProActive Vessel Register Compliance Report, which ISSF publishes to coincide with the annual report. In addition to reporting ISSF participating companies’ performance on ISSF conservation measures, the report now also shows PVR vessels’ aggregate compliance on relevant ISSF conservation measures.

For 23 ISSF participating companies as of December 2023, the ISSF Annual Conservation Measures & ProActive Vessel Register Compliance Report shows a conformance rate of 98.95%. It tracks companies’ progress in conforming with ISSF’s 33 conservation measures, such as:

  • Submitting quarterly purchase data by vessel, trip dates, species, size and other data to RFMO scientific bodies
  • Conducting transactions only with purse seine vessels whose skippers have received science-based information from ISSF on best practices such as reducing bycatch
  • Avoiding transactions with vessels that are on an RFMO IUU fishing list

For PVR-listed vessels, the report shows an aggregate compliance rate of 75.78% with the 12 ISSF conservation measures that directly address vessel activity, including RFMO Participation; Transactions with Vessels that Use Only Non-entangling FADs; Vessel-based FAD Management Policy; and Observer Coverage, for example. Vessel participation in these measures is shown in columns on the PVR.

As part of its commitment to transparency and accountability, ISSF engages third-party auditor MRAG Americas to audit participating companies to assess their compliance with ISSF’s conservation measures. MRAG Americas conducts independent auditing based on a rigorous audit protocol. MRAG Americas also audits the vessels on the PVR for compliance against the ISSF conservation measures that are tracked on the vessel list.

In addition to the summary compliance report, MRAG Americas issues individual reports that detail each participating company’s compliance with ISSF’s conservation measures. ISSF publishes these individual company compliance reports on its website. Individual PVR vessel compliance information can also be found on the PVR list on the ISSF website.

ISSF Publishes First-Ever Jelly-FAD Construction Guide to Help Fishers Build Netting-free, Biodegradable FADs for More Sustainable Tuna Fishing

The International Seafood Sustainability Foundation (ISSF) has published a comprehensive step-by-step guide that shows commercial tuna fishers how to build “jelly-FADs” — an innovative, nearly 100% biodegradable and non-entangling design for fish aggregating devices (FADs).

For many years, FADs have been a widely used fishing strategy due to their high efficiency for catching tuna. About 38% of the global tuna catch, which totaled 5.2 million tonnes in 2022, is made with FADs. But conventional FADs can have negative impacts, such as contributing to overfishing, bycatch, and marine pollution.

To reduce FAD fishing’s effects on non-target marine animals and ocean ecosystems, ISSF scientists developed the jelly-FAD in collaboration with physical oceanographers from the Institut de Ciències del Mar (CSIC) and tuna fleets — testing and refining the design through workshops, lab research, and at-sea trials in real fishing conditions.

Inspired by the neutral buoyancy of jellyfish, the jelly-FAD design not only is made without netting but also is almost completely biodegradable, and it offers additional sustainability and durability advantages over previous non-entangling FAD (NEFAD) and biodegradable FAD (bio-FAD) designs.

Practical Guide for Tuna Fishers

To help facilitate broad fleet adoption of jelly-FADs, ISSF’s Jelly-FAD Construction Guide provides detailed instructions and visuals for each step in the construction process. These steps include:

  1. Prepare the Canvas – canvas sheets are part of the jelly- FAD “drogue” or cube
  2. Build the Drogue (Cube) – a three-dimensional “drogue” or cube keeps the FAD in the fishing grounds
  3. Add a Submerged Buoy – a submerged buoy works for flotation
  4. Build the Raft – the structure must resist wind and ocean wave drag forces
  5. Make the Flotation Component – a water-line flotation piece

The guide also recommends how to deploy and fully transition to jelly-FADs.

“The Jelly-FAD Construction Guide shows tuna fishers how to build what we believe is the most sustainable non-entangling FAD to date,” said Dr. Gala Moreno, ISSF senior scientist. “The jelly-FAD represents a new concept in drifting FADs (DFADs), whose structure and materials have been relatively static for decades. To make jelly-FADs, you do not need to have unusual materials, special equipment, or advanced carpentry skills. We intend the jelly-FAD to be as simple and affordable as possible for fishers around the world to build.”

Our research team designed jelly-FADs to greatly reduce the need for plastic in FAD construction. Fishers have options in what kinds of biodegradable materials they choose: they can build jelly-FADs with bamboo, canvas, cork, clay, and cotton rope, for example. In contrast, conventional FADs for decades have been made with netting materials, plastic, and metal.

“The jelly-FAD we present in the Guide is more of a model for tuna fishers than a fixed design. We expect fishers to help evolve the concept,” explains Moreno. “The current drogue or cube could potentially be replaced by a cylinder or another type of three-dimensional structure, for example. But the concept of neutral buoyancy should be maintained so that the FAD, which is made of organic materials, can last as long as fishers need, which varies from four months to one year depending on the fleet. Recent trials with the jelly-FAD in the Eastern Pacific Ocean showed fishers were still fishing on them after one year at sea. Periodic repairs on jelly-FADs may allow them to last longer.”

Jelly-FAD Training Workshops, Research Partners, and Funders

Moreno and colleagues have been introducing the jelly-FAD model to fishers at workshops worldwide. Tuna fleets interested in learning more about the jelly-FAD or requesting training can contact ISSF at [email protected].

ISSF partnered with Ugavi, Caroline Fisheries Corporation, and Pevasa fleets on the initial stages of the jelly-FAD  design and testing process, with contributions from Dr. Lauriane Escalle and James Wichman at the Pacific Community (SPC), Joaquín Salvador at the Institut de Ciències del Mar (CSIC), and Iker Zudaire at AZTI.

ISSF’s jelly-FAD research was supported by the Global Environmental Facility (GEF) through the Common Oceans Tuna Project, implemented by the Food and Agriculture Organization (FAO), which is a unique and innovative partnership working towards transformational change in tuna fisheries management and biodiversity in areas beyond national jurisdiction. Additional funders are ISSF, National Oceanic and Atmospheric Administration (NOAA) fisheries, and the Basque Government.

ISSF Web Feature Explores Challenges and Solutions in FAD Fishing

Complementing the Jelly-FAD Construction Guide is “Fresh Thinking About FADs” — a new, immersive ISSF Web feature that illustrates ISSF’s efforts to foster sustainable fishing approaches, including the jelly-FAD.

“Fresh Thinking” tells the visual story of improving FAD design and management as readers scroll through interactive content that includes animated infographics and under-water photography. It describes how FADs have changed over time; the environmental drawbacks of conventional FAD designs; the jelly-FAD characteristics that help to reduce bycatch and ocean pollution; and science-based solutions for more sustainable FAD design and management, which ultimately support healthier tuna fisheries and oceans.

“No fishing method is without impact, but collaborative efforts are making fishing with FADs more sustainable,” noted Dr. Victor Restrepo, Vice President, Science, ISSF. “We still have work to do toward improving the use of FADs while ensuring that there are plenty of fish in the sea. But we’ve made substantial progress to date. ISSF and likeminded organizations will continue to work toward achievable, science-based solutions for reducing the impact of FAD fishing on global tuna fisheries and the broader marine ecosystem.”

ISSF REPORT: 86% of Global Tuna Catch Comes from Stocks at Healthy Levels; 10% Requires Stronger Management

Of the total commercial tuna catch worldwide, 86% comes from stocks at “healthy” levels of abundance, according to the newest International Seafood Sustainability Foundation (ISSF) Status of the Stocks report released in March 2024 — a 1% improvement over 2023 report findings. Additionally, overfished stocks now account for 10% of the total catch — down from 11% in the previous report. The percentage of the catch that came from stocks at an intermediate level of abundance remained unchanged, at 4%.

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

  • Mediterranean albacore, Indian Ocean bigeye, and Indian Ocean yellowfin stocks are overfished and subject to overfishing.
  • Pacific Ocean bluefin is overfished.

In terms of Regional Fisheries Management Organizations (RFMO) stock management, key updates since November 2023 include:

  • A Western and Central Pacific Ocean (WCPO) management change: Specifically, the Western and Central Pacific Fisheries Commission (WCPFC) updated the tropical tuna conservation measure, which now encourages member countries to initiate retrieval programs for lost, abandoned or stranded FADs, while shortening the FAD closure from 3 to 1.5 months.
  • A Pacific-wide management change: Specifically, the WCPFC updated its harvest strategy by adopting a Harvest Control Rule for North Pacific albacore like the one adopted by the Inter-American Tropical Tuna Commission (IATTC) in 2023.
  • The Indian Ocean Tuna Commission (IOTC) released updated catch data as well as a new Indian Ocean skipjack stock assessment that found no change in ratings. Based on the results of the assessment, a new total allowable catch (TAC) was adopted following the application of the Harvest Control Rule.

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

Key Statistics in the New Status of the Stocks Report

  • Abundance or “spawning biomass” levels: Globally, 61% of the stocks are at a healthy level of abundance, 22% are at an intermediate level, and 17% are overfished (unchanged from the November 2023 report).
  • Fishing mortality levels: 78% of the 23 stocks are not experiencing overfishing, 13% are experiencing overfishing, and 9% are at an intermediate level (unchanged from the November 2023 report).
  • Tuna production by fishing gear: 66% of the catch is made by purse seining, followed by longline (9%), pole-and-line (7%), gillnets (4%) and miscellaneous gears (14%).
  • 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 yellowfin.
  • Total catch: The catch of major commercial tunas was 5.2 million tonnes in 2022, a 2% increase from 2021. Fifty-seven percent of it was skipjack tuna, followed by yellowfin (30%), bigeye (7%) and albacore (5%). Bluefin tunas accounted for 1% of the global catch.

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

New Report Available: Tuna Fisheries’ Impacts on Non-Tuna Species and Other Environmental Aspects: 2024 Summary

Until 2023, the Status of the Stocks report included relative ratings for bycatch impacts by the different fishing methods. The information on stock status and management comes from the five tuna RFMOs that assess and regulate tuna fisheries internationally. However, the information on bycatch impacts was from multiple sources and was not stock- or fishery-specific. Because of this, the ISSF SAC recommended that the Status of the Stocks report be limited to stock status and management and a separate report be created to address the environmental impacts.

Subsequently, the separate ISSF report entitled Tuna Fisheries’ Impacts on Non-Tuna Species and Other Environmental Aspects: 2024 Summary was published in March 2024 to summarize bycatch and other ecosystem impacts for major types of tuna fisheries. Going forward, ISSF will publish this report annually as a standalone publication.

Key elements in the March 2024 report include:

  • A summary of the main impacts that different methods used to catch tunas have on non-target species and other ecosystem components
  • An analysis of scores obtained by different fishery types in Principle 2 (environmental impacts) certified by the Marine Stewardship Council (MSC)
  • A summary of the relevant measures to address ecosystem impacts adapted by the tuna RFMOs
  • A summary of complementary conservation measures adopted by ISSF

About the Status of the Stocks 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. Status of the Stocks assigns color ratings (green, yellow or orange) using a consistent methodology based on two factors: Abundance and Exploitation/Management (fishing mortality).

ISSF produces several Status of the Stocks reports each year 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 MSC Criteria provides scores for the stocks and RFMOs based on MSC assessment criteria. 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, filter by location and species, and see the share of total catch by species/stocks and gear types.

ISSF Urges WPCFC to Improve Compliance Processes and to Adopt New Tropical Tuna Conservation Measure and Harvest Control Rule for North Pacific Albacore Tuna

The International Seafood Sustainability Foundation (ISSF) has issued its position statement for consideration by the Western and Central Pacific Fisheries Commission (WCPFC) ahead of its 20th regular session from December 4-8, 2023, in Rarotonga, Cook Islands. The statement leads with a call for improved compliance processes.

“Regional fisheries management organizations (RFMOs) need strong and transparent compliance processes in order to meet their objectives, strengthen their performance, and be accountable to their many and diverse stakeholders,” said ISSF President Susan Jackson. “Yet the WCPFC is the only tuna RFMO with a compliance assessment process that is closed to accredited observers. That’s why our position statement leads with a call for the Commission to develop guidelines for the observer participation in compliance assessment processes.”

Other issues addressed in the statement include tuna stock conservation and effective management procedures, FAD management, electronic monitoring, transshipment regulations, bycatch mitigation, and shark protections.

“The WCPFC also has the opportunity to progress tuna stock conservation. The Western and Central Pacific Ocean (WCPO) is the world’s largest tuna fishing ground, and due to persistent management, no tuna stocks in the WCPO are currently overfished or experiencing overfishing,” Jackson continued. “For these stocks to remain healthy, managers must continue to implement scientific advice and take a precautionary approach.

“Specifically, the Commission adopted management procedures (MP) for skipjack tuna and North Pacific albacore last year. This year, it must operationalize these MPs by implementing the outputs of the skipjack management procedure in the revised tropical tuna measure and by adopting a harvest control rule for North Pacific albacore. A new and improved conservation measure for tropical tunas that includes strengthened measures for fish aggregating devices (FADs) is also a must.”

Priorities for Western and Central Pacific Ocean Tuna Fisheries

Compliance Processes

  • Direct the Compliance Monitoring Scheme Intersessional Working Group to develop guidelines for the participation of accredited observers, as well as a scheme of responses to non-compliance, to present to the Commission for adoption in 2024

Tuna Stock Conservation and Effective Management Procedures (Harvest Strategies)

  • Adopt a new conservation measure for tropical tunas that:
    • Implements the outputs of the 2023 skipjack Management Procedure
    • Limits fishing mortality for bigeye and yellowfin to the interim Target Reference Points
    • Removes ambiguities and exemptions
    • Sets catch limits for fisheries that do not have them
  • Adopt a harvest control rule for North Pacific albacore to implement the harvest strategy for North Pacific albacore fishery adopted by the Commission in 2022
  • Adopt Target Reference Points and continue to develop Management Procedures for bigeye and yellowfin tuna
  • Ensure that the skipjack Management Procedure adopted last year is effectively implemented in the revised tropical tuna measure and adopt a monitoring strategy consistent with scientific advice

FAD Management

  • Establish an interim timeline, to be reviewed in 2024, for transitioning to 100% biodegradable FADs consistent with the timeline agreed by the IATTC
  • Adopt a requirement for provision of near-real-time FAD position and acoustic biomass data for scientific use, with appropriate time-lags to protect confidentiality
  • Task the FAD Working Group with developing in 2024:
    • A “FAD logbook” similar to what is used by the Parties to the Nauru Agreement
    • Options for increased FAD detection and recovery
    • Guidelines to minimize the impact of FADs on sea turtles

Electronic Monitoring & Observer Coverage

  • Task the Electronic Reporting and Electronic Monitoring Intersessional Working Group with finalizing Electronic Monitoring (EM) standards, specifications, and procedures for adoption in 2024
  • Adopt a timeline and plan to substantially increase observer coverage in longline fisheries

Transshipment Regulation

  • Strengthen the regulation of at-sea transshipment in line with best practice standards, including requiring:
    • Near-real-time electronic reporting (not longer than 24 hours after the event) for all transshipment activity, using minimum standard data fields
    • Use of automatic identification systems (AIS) and that vessel monitoring system (VMS) data are reported for all transshipments of WCPFC-covered species
    • Provision of observer data to the WCPFC, as well as the national program
    • Establishing criteria for authorization of at-sea transshipment and a review process

Bycatch Mitigation & Shark Protections

  • Task the Scientific Committee (SC) and the Technical and Compliance Committee (TCC) with reviewing the seabird and sea turtle measures in 2024, and providing advice on updated best practice mitigation options
  • Task the SC and TCC to provide recommendations in 2024 on the conservation measure for sharks, including the provisions for retained sharks to be landed with fins naturally attached.

ISSF REPORT: 85% of Global Tuna Catch Comes from Stocks at Healthy Levels; Stock Status Remains Unchanged Since March 2023 Report

Of the total commercial tuna catch worldwide, 85% comes from stocks at “healthy” levels of abundance, according to the newest International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. Overfished stocks accounted for 11% of the total catch, and 4% of the catch came from stocks at an intermediate level of abundance.

No individual stock statuses have changed since the March 2023 Status of the Stocks report. The updated report incorporates recent stock-assessment results for Western Pacific bigeye, Western Pacific yellowfin, North Pacific albacore, North Atlantic albacore, and Southern bluefin, none of which has changed. The lack of substantial changes in stock status between report periods highlights the value of continuous scientific assessments to inform stock-management decisions.

The report did find that several tuna stocks are considered overfished and/or subject to overfishing:

  • Mediterranean albacore, Indian ocean bigeye and Indian Ocean yellowfin stocks are overfished and subject to overfishing.
  • Pacific Ocean bluefin is overfished.

In terms of RFMO stock management, key updates since March 2023 include:

  • IATTC established new conservation measures for tropical tuna FAD fisheries in the Eastern Pacific Ocean, including encouraging member states to initiate drifting-FAD recovery programs and establish deadlines for a stepwise transition to using fully non-entangling (required from 2025 onwards) and biodegradable FADs (gradually, until 2029), respectively.
  • IATTC adopted a full harvest strategy and Harvest Control Rule for North Pacific albacore.
  • IOTC and CCSBT endorsed total allowable catch (TAC) recommendations for Indian Ocean bigeye and Southern bluefin, respectively, based on the outcome of each stock’s management procedure.

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.

Key Statistics in the New Report

  • Abundance or “spawning biomass” levels: Globally, 61% of the stocks are at a healthy level of abundance (unchanged from the March 2023 report), 22% are at an intermediate level, and 17% are overfished.
  • Fishing mortality levels: 78% of the 23 stocks are not experiencing overfishing, 13% are experiencing overfishing, and 9% are at an intermediate level.
  • Tuna production by fishing gear: 66% of the catch is made by purse seining, followed by longline (9%), pole-and-line (8%), gillnets (4%) and miscellaneous gears (13%).
  • 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.
  • Total catch: The catch of major commercial tunas was 5.1 million tonnes in 2021. Fifty-seven percent of it was skipjack tuna, followed by yellowfin (31%), bigeye (7%) and albacore (4%). Bluefin tunas accounted for 1% of the global catch.

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

About the Status of the Stocks 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. 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 several Status of the Stocks reports each year 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. 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, filter by location and species, and see the share of total catch by species/stocks and gear types.
