ISSF Report: 15 Tuna Stocks Not Meeting Criteria for Marine Stewardship Council (MSC) Sustainability Standard

Independent fisheries scientists in a March 2020 report from the International Seafood Sustainability Foundation (ISSF) found that four out of 19 major commercial tuna stocks worldwide are being managed to avoid overfishing and to maintain target stock biomass levels: North Atlantic Albacore, Western Pacific Skipjack, South Pacific Albacore, and Indian Ocean Skipjack. These four stocks earned a passing score against the Marine Stewardship Council (MSC) Fisheries Standard on its Principle 1 on “Sustainable Fish Stocks.”

MSC is an independent, international, non-profit organization that oversees a program to assess wild-capture fisheries and certify them as “sustainable” if they meet its Fisheries Standard criteria. In the January 2019 edition of the ISSF report, five stocks passed Principle 1 (Eastern Pacific Yellowfin no longer does).

ISSF 2020-09: An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria attributes 15 other tuna stocks’ inability to pass MSC Principle 1 to poor stock status, the lack of well-defined harvest control rules (HCRs), and the lack of effective tools to control harvest.

Notable Report Findings

One of the 19 stocks — North Pacific Albacore — triggered the implementation of well-defined HCRs, and there has been some HCR progress on other tuna stocks by all tuna Regional Fisheries Management Organizations (RFMOs). RFMOs are governing bodies whose member nations are responsible for setting catch limits, monitoring the health of stocks, and regulating the right to fish. However, HCRs often have not been implemented until rebuilding is required.

  • Atlantic Ocean Yellowfin’s Principle 1 score improved since the last reporting period, but the scores of Indian Ocean Bigeye and Indian Ocean Albacore both declined. However, data on the latter has improved in quality and should be sufficient to support a harvest strategy.
  • Uncertainty in assessments remains a concern in the Eastern Pacific, as the 2019 stock assessment of Eastern Pacific Yellowfin found inadequacies in both the model and data, which hinders stock management advice and harvest control rule actions. 

ISSF’s report was authored by Paul A. H. Medley, Jo Gascoigne, and Jo Akroyd.

About the Report

An Evaluation of the Sustainability of Global Tuna Stocks takes a consistent, comprehensive approach to scoring tuna stocks against certain components of the MSC standard. The MSC is a global certification program for fisheries.

The report — updated regularly since it was first published in 2013, and conveniently 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 four RFMOs, and comprehensive reference citations.

The report does not address bluefin tuna stocks.

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.”

Regarding stocks receiving passing scores:

  • Among seven tuna stocks in the Atlantic Ocean, one received an overall principle-level passing score: Northern Albacore.
  • Among eight tuna stocks in the Pacific Ocean, two received overall principle-level passing scores: Western Skipjack and Southern Albacore.
  • Among four stocks in the Indian Ocean, one received an overall principle-level passing score: Skipjack.

Regarding stocks receiving failing scores:

  • In the Pacific, six stocks received overall principle-level failing scores: Western Yellowfin, Eastern Yellowfin, Northern Albacore, Eastern Bigeye, Eastern Skipjack and Western Bigeye.
  • In the Indian Ocean, Yellowfin, Bigeye and Albacore all received overall principle-level failing scores.
  • In the Atlantic, Yellowfin, Bigeye, Western Skipjack, Eastern Skipjack, Southern Albacore and Mediterranean Albacore all received principle-level failing scores.
  • The two stocks that require rebuilding are Atlantic Bigeye and Indian Ocean Yellowfin.

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.

All four RFMOs received overall principle-level passing scores from the authors.

See a graphic showing MSC Principle 3 averages from December 2013-March 2020.

While the report focuses on tuna stock status and sustainability as well as on RFMO policies, it does not address national or bilateral fishing jurisdictions, 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.

Her winning proposal calls for cooperative workshops with purse-seine skippers and observers, offering financial rewards for the design, testing, and onboard implementation of feasible, scalable techniques for safely removing rays from vessel decks.

It also includes training observers in tagging rays to track their post-release survival. Rays, in addition to sharks, are the species groups most vulnerable in the purse-seine fishery. In the Indian Ocean, for example, rays comprise the majority of bycatch in tuna fishers’ free-school sets: bycatch overall on such sets represents 0.9% of the total catch, and 34% of that is rays.

In addition to the $40,000 Grand Prize, the award includes a trip, with an estimated $5,000 value, to a tuna event. ISSF will arrange for Ms. Cronin to present her proposal at a Regional Fisheries Management Organization (RFMO) event this year.

Winning Proposal Builds on ISSF Scientist-Fisher Collaboration

Dr. Victor Restrepo, ISSF Vice President, Science and Chair of the ISSF Scientific Advisory Committee (SAC), led the contest’s judging panel. “Through this competition, we’re pleased to reward promising research ideas from up-and-coming marine and fisheries scientists,” he commented. “Ms. Cronin’s thoughtful proposal is based on collaborative problem-solving between fishers and scientists — a successful model ISSF follows in our Skippers Workshops worldwide. Our workshops have focused on finding new approaches in tuna fisheries to protect sharks and other non-tuna species, for example.”

The judging panel evaluated contest entries on the following criteria: originality, conservation impact, impact on skipjack catches, degree to which idea has been tested, feasibility of industry-wide implementation, and cost effectiveness. In addition to Dr. Restrepo, the panel included Dr. Josu Santiago, AZTI; Dr. Laurent Dagorn, Institut de Recherche pour le Développement (IRD); Dr. Gala Moreno, ISSF Science Consultant; and Miguel Herrera, OPAGAC Scientist.

Runner-Up Prize Winning Entry Focuses on Oceanic Sharks

Guillermo Ortuno Crespo, a researcher at the Marine Geospatial Ecology Lab at Duke University, receives a $10,000 prize as the contest Runner-up Winner for his proposal, “Dynamic Habitat Predictions of Two Bycaught Oceanic Shark Species.” His proposal focuses on predicting the dynamic, spatial distribution of non-target and sometimes target species based on their environmental preferences.

Mr. Crespo’s study explores the dynamic habitats of Carcharhinus longimanus and C. falciformis in the Inter-American Tropical Tuna Commission (IATTC) region, to help predict where fisher-shark bycatch interactions are likely to occur.

The ISSF Seafood Sustainability Contest  commemorated ISSF’s first “Decade of Discovery” (2009-2019), which has been marked by productive partnerships with marine scientists, seafood companies, vessels, Regional Fisheries Management Organizations (RFMOs), charitable foundations, retailers, and fellow NGOs.

We look forward to his advice and counsel, especially in that critical part of the tuna-fishing world.” 

About the Environmental Stakeholder Committee

The ISSF Board receives information from formal and informal partners — environmental stakeholders marine scientists, fishers, and vessel owners — who share insights from the field.

The ESC comprises expert representatives from various conservation and scientific bodies who volunteer to share their expertise. The ESC, as does ISSF’s Scientific Advisory Committee (SAC), provides advice to the ISSF Board of Directors on issues to consider before taking action on specific sustainability efforts, including regarding ISSF conservation measures that ISSF Participating Companies commit to conform to with the goal of improving the long-term health of global tuna fisheries.

Latest ISSF Participating Tuna Company Compliance Report Shows 99 Percent Conformance with ISSF Conservation Measures

The International Seafood Sustainability Foundation (ISSF) has released its fourth annual Update to ISSF Conservation Measures & Commitments Compliance Report, which shows a conformance rate of 99 percent by 25 ISSF participating companies with all 27 ISSF conservation measures in effect as of 2018.

As part of its commitment to foster transparency and accountability in the fishing industry, ISSF engages third-party auditor MRAG Americas to assess ISSF participating seafood companies’ compliance with ISSF conservation measures according to a rigorous audit protocol.

ISSF participating #seafood companies have regularly surpassed 90% full conformance with ISSF #conservation measures. Click To Tweet

The November 2019 report is based on updates to the initial annual audit results published in April 2019, wherein some companies had “minor” or “major” non-conformances with conservation measures in 2018:

  • The April 2019 annual report showed that one company had a major non-conformance, which had been remediated as of the November 2019 report’s release.
  • There were no other instances of major non-conformance in 2018.
  • ISSF also noted in the November 2019 report that eight participating companies had at least one minor non-conformance, for a total of nine minor non-conformances.

MRAG Americas defines a minor non-conformance as: “Company does not fully comply with a particular conservation measure or commitment, but this does not compromise the integrity of ISSF initiatives.”

The rate of full conformance for each period since participating-company compliance reporting began is reflected below:

Annual compliance report Update to annual compliance report
June 2015: 79.8 percent No Update report published in 2015
June 2016: 87.2 percent November 2016: 95.6 percent
May 2017: 97.5 percent November 2017: 100 percent
June 2018: 97 percent November 2018: 99 percent
April 2019: 98.5 percent November 2019: 99 percent

“As we close a year of celebrating ISSF’s decade of discovery, we are pleased to reflect on consistent years of company-specific, third-party compliance reporting,” said ISSF President Susan Jackson.

“There’s been a 100 percent success rate in ISSF participating companies addressing major non-conformances for the last three audit years, and these companies have regularly surpassed 90 percent in their rate of full conformance with a growing list of ISSF conservation measures. The ISSF audit and compliance process holds industry participants to a higher, completely transparent, standard, making sustainability a core part of their overall strategy.”

The Update to ISSF Conservation Measures & Commitments Compliance Report is published each November to track ISSF participating companies’ progress in conforming with ISSF conservation measures like these:

In addition to the summary compliance reports published in April and November, MRAG Americas issues yearly individual ISSF participating company reports that detail each company’s compliance with all ISSF conservation measures. These include “update” reports, published throughout the year, that explain how individual companies have remediated any non-conformance on the conservation measures.

ISSF Announces New Conservation Measure to Bolster Fish Aggregating Device (FAD) Management across Global Tuna Fisheries

The International Seafood Sustainability Foundation (ISSF) today announced the adoption of a new conservation measure requiring that fishing vessels have publicly available fish aggregation device (FAD) management policies to comply with ISSF supply-chain recommendations for marine ecosystem health. These policies must be in line with science-based best practices outlined in ISSF’s report, “Recommended Best Practices for FAD Management in Tropical Tuna Purse Seine Fisheries.”

Our new #conservation measure helps companies source #tuna from #vessels following best practices in #FAD management. Click To Tweet

“Since ISSF’s founding 10 years ago, we’ve prioritized better management of FADs and the reduction of bycatch and other marine ecosystem impacts across all oceans,” explains ISSF President Susan Jackson. “This new conservation measure gives leading seafood companies a clear framework, based on years of scientific research, in sourcing tuna from vessels that are following best practices in designing, deploying, and recovering FADs — and also in reporting FAD data to Regional Fisheries Management Organizations (RFMOs).”

ISSF Conservation Measure 3.7 Transactions with Vessels or Companies with Vessel-based FAD Management Policies, approved by the ISSF Board of Directors to take effect in 2021, states that ISSF participating companies shall conduct transactions only with those purse seine vessels whose owners develop and make public FAD management policies that include the activities purse seine and supply vessels are undertaking (if any) on the following elements:

  • Comply with flag state and RFMO reporting requirements for fisheries statistics by set type
  • Voluntarily report additional FAD buoy data for use by RFMO science bodies
  • Support science-based limits on the overall number of FADs used per vessel and/or FAD sets made
  • Use only non-entangling FADs to reduce ghost fishing
  • Mitigate other environmental impacts due to FAD loss including through the use of biodegradable FADs and FAD recovery policies
  • For silky sharks (the main bycatch issue in FAD sets), implement further mitigation efforts

Helping global tuna fisheries become capable of achieving Marine Stewardship Council (MSC) certification without conditions has long been an ISSF objective, and improved FAD management is an important component of meeting the MSC standard. Conservation Measure 3.7 is ISSF’s second measure focused on FADs specifically, and its tenth measure focused on bycatch mitigation in tuna fisheries.

Supply Chain Conservation Measure Expanded to Include FisheryProgress.org and MSC-certified Fisheries

ISSF conservation measures directly affect how 26 global seafood companies that are ISSF participating companies environmentally manage their respective tuna supply chains.

To support ISSF participating companies in sourcing sustainable tuna from processors and vessels and achieving greater supply-chain transparency, the ISSF Board has amended Conservation Measure 2.4 Supply Chain Transparency, Audit, Reporting and Purchase Requirements.

In addition to purchasing tuna from Supplier Source categories — peer ISSF participating companies, ISSF Data Check companies, direct from vessels — ISSF participating companies now can source tuna from an expanded array of sources represented by these Fishery Source categories:

  • Marine Stewardship Council (MSC)-certified fisheries eligible to use the MSC label
  • Comprehensive FIPs listed on FisheryProgress.org scoring A, B or C or in their initial listing on Fisheryprogress.org
  • Comprehensive FIPs listed on FisheryProgress.org scoring D or E

By January 31, 2020, and annually thereafter, to comply with measure 2.4, participating companies must publicly report the percentage of tuna sourced from the Supplier Source and/or Fishery Source categories.

The complete measure is available here: https://www.iss-foundation.org/what-we-do/verification/conservation-measures-commitments/traceability-data-collection-2-4-supply-chain-transparency-audit-reporting-and-purchase-requirements/.

ISSF provides application forms for companies interested in becoming a participating company or Data Check company, including Terms and Conditions for Data Check Companies.

About ISSF Conservation Measures & Compliance Process

ISSF is a global partnership among scientists, the tuna industry and the environmental non-governmental community whose mission is to undertake science-based initiatives for the long-term conservation and sustainable use of tuna stocks, reducing bycatch and promoting ecosystem health.

Since its inception in 2009, ISSF has adopted conservation measures and commitments to facilitate this mission with the intent that processors, traders, marketers and others involved in the seafood industry will follow them to facilitate real and continuous improvement across global tuna stocks. Each ISSF participating company commits to conform to these conservation measures to improve the long-term health of tuna fisheries. They also must adhere to the ISSA Compliance Policy.

ISSF-participating tuna companies, which represent the majority of the world’s canned-tuna production and include well-known brand names, are audited yearly by MRAG Americas on their compliance with ISSF conservation measures.
