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.”

“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.

81% of Global Tuna Catch Comes from Stocks at Healthy Levels, While 15% Require Stronger Management

Of the total commercial tuna catch worldwide, 81% came from stocks at “healthy” levels of abundance, according to the October 2019 International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. In addition, 15% of the total tuna catch was from overfished stocks, and 4% was from stocks at an intermediate level of abundance.

Globally, 61% of 23 #tuna stocks are at a healthy level of abundance, 17% are #overfished, and 22% are at an intermediate level. Share on X

Albacore and skipjack stocks in all four major tuna fishing regions are rated as healthy, but several tuna stocks worldwide are considered overfished:

  • The Atlantic Ocean bigeye and Indian Ocean yellowfin tuna stocks are overfished and overfishing is taking place.
  • Noting the high uncertainty levels in stock assessments, ISSF is taking a cautious view and considers that the Eastern Pacific Yellowfin and Bigeye tuna stocks are experiencing overfishing and that the Yellowfin stock is overfished.
  • Overfishing is occurring on the Pacific bluefin tuna stock and the stock is heavily overfished.

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, 61% of the 23 stocks are at a healthy level of abundance, 17% are overfished and 22% are at an intermediate level.
  • Fishing mortality levels: 78% of the 23 stocks are experiencing a well-managed fishing mortality rate, and 22% are experiencing overfishing.
  • Total catch: In 2017, as reported in the new report, the total major commercial tuna catch was 4.9 million tonnes, a decrease of 2% from 2016. More than half of the total catch (56%) was skipjack tuna, followed by yellowfin (30%), bigeye (8%) and albacore (5%). Bluefin tunas (three species) accounted for 1% of the global catch. These percentages changed only slightly from the previous Status of the Stocks report.
  • 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 ocean region: More than half (52%) of the world’s tuna is harvested from the Western and Central Pacific Ocean, followed by the Indian Ocean (20%), Eastern Pacific Ocean (13%) and Atlantic Ocean (11%). Catch from Pacific-wide stocks accounts for around 3% of the global catch, while catch in the Southern Hemisphere accounts for less than 1%.
  • Tuna production by fishing gear: 65% of the catch is made by purse seining, followed by longline (11%), pole-and-line (8%), gillnets (4%) and miscellaneous gears (12%). These percentages have not changed 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.

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 several times 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 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 (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 stock health indicators and filter by location, species and other key stock health and catch factors.

ISSF Releases New Non-Entangling and Biodegradable FADs Guide for Fishers, RFMOs, Governments and Vessel Owners

The International Seafood Sustainability Foundation (ISSF) has published a best-practices guide — based on years of ISSF scientific research and fleet collaboration worldwide, including at skippers workshops — to help tuna fishers accelerate their use of fish aggregating device (FAD) designs with the least possible impact on the marine ecosystem.

The ISSF Non-Entangling and Biodegradable FADs Guide is the first manual to show, through detailed illustrations, non-entangling (NE) FAD raft and tail designs made with biodegradable materials.

By not using netting in FADs, tuna-vessel owners and fishers can prevent the entanglement and “bycatch” of sharks, sea turtles, and other non-target marine species — a serious issue addressed in the guide. In addition, by choosing vegetal instead of plastic-derived materials for FADs, fishers can avoid contributing to the ocean pollution caused by discarded fishing gear. A study estimated that 10% of FADs deployed in tuna fisheries end up stranded and can ensnare sharks and turtles as they drift, a phenomenon known as “ghost fishing.” (Maufroy et al. 2015)

A Resource for Sustainable Fishing Stakeholders

ISSF’s Non-Entangling and Biodegradable FADs Guide also summarizes Regional Fisheries Management Organization (RFMO) requirements for FAD designs. For example, as of 2018, four tuna RFMOs require tuna fishers to use NE designs for FADs; however, they only encourage, rather than require, fishers to use biodegradable materials.

“Through our long-running Skippers Workshop program with purse-seine fishers, we’ve observed their growing commitment to better protect marine species and habitats — and their willingness to switch to NE FADs as a necessary step,” says Dr. Victor Restrepo, ISSF’s Vice President of Science. “With help from practical resources like this guide, fishers can make progress in using biodegradable materials for NE FAD designs — and we also hope to see RFMOs require fully non-entangling and biodegradable designs for FAD fishers.”

The Non-Entangling and Biodegradable FADs Guide, which was authored by ISSF scientists with input from ISSF’s Scientific Advisory Committee and Bycatch Steering Committee, can assist RFMO and government policymakers in adopting more rigorous, science-based measures for lower-impact FAD designs.

The guide can be downloaded in English from the ISSF site. Later this fall, Chinese (Traditional and Simplified), Japanese, Korean, French, Indonesian, Spanish, Tagalog and Vietnamese versions will be published. This is the second update of the ISSF NE FAD guide since it was first published in 2012.

ISSF’s 10th anniversary timeline highlights a decade of achievements in FAD research, from a November 2009 bycatch-mitigation workshop to current biodegradable FAD pilot studies in four RFMO regions.

ISSF Welcomes Filipino Company Ocean Canning Corporation as New Participating Company

Philippines company Ocean Canning Corporation is the latest seafood company to join in the conservation efforts of the International Seafood Sustainability Foundation (ISSF). ISSF participating companies work with the Foundation to advocate for sustainable tuna fishery management and encourage the adoption of responsible fishing practices.

“We are pleased to welcome Ocean Canning Corporation as an ISSF participating company. Industry engagement is a core component of what we do and is integral in advancing our conservation objectives,” said ISSF President Susan Jackson. “Engaging tuna companies around the world to help them appreciate the importance of sustainably-minded practices, as well as expecting them to commit to conform to ISSF’s science-based conservation measures, is critical to improving the long term health of global tuna fisheries. And the addition of companies from Southeast Asia like Ocean Canning is evidence of the Foundation’s growing global reach.”

Ocean Canning Corporation, established in 1997, is a private tuna canner, processor and exporter based in General Santos City, Philippines.

All ISSF participating companies are independently and comprehensively audited annually to assess their compliance with ISSF’s conservation measures, the results of which are published in the ISSF compliance report and the ISSF annual report. ISSF also publishes individual compliance reports for each ISSF participating company.

ISSF launched in 2009 with eight participating companies and today has 26 industry partners, including well-known brands produced and sold in North America, South America, Europe, Africa, Oceania, the Pacific Islands and Asia.

Report: At Least 1,843 Purse Seine Vessels Fishing for Tuna Worldwide Today, A Slight Decrease versus 2018 Analysis

The International Seafood Sustainability Foundation (ISSF) has issued an updated “snapshot” of Large-Scale Tuna Purse Seine Fishing Fleets report as of June 2019. The total number of purse seine vessels, calculated based on data from the five tuna Regional Fisheries Management Organizations (RFMOs), has decreased from 1,871 in 2018 to 1,843 today, mainly due to the removal from RFMO lists of vessels under 24m that are now inactive. 

In the tropical #tuna large-scale #purse #seine fleet, fish hold volume grew by 1% since 2018. Share on X

Having an accurate estimate of active vessels is critical for managing tuna fishing capacity regionally as well as globally. Although purse seine vessels account for approximately 65 percent of the 4.9-million-tonne global tuna catch, multiple databases must be searched to count all authorized purse seine vessels. To provide an annual best estimate — and to track capacity changes from year to year — ISSF analyzes and aggregates information from the five tuna RFMOs and other sources. As the report explains, these figures may underestimate the total fleet, because many small-scale purse seiners or purse seiners operating in only one exclusive economic zone (EEZ) do not have to be listed on RFMOs’ records of authorized fishing vessels.

Through its research, ISSF found that in the tropical tuna large-scale purse seine (LSPS) fleet, fish hold volume (FHV) grew by 1 percent since 2018. The report shows approximately 686 vessels (up 2 percent, from 673 last year) defined as large-scale purse seine (LSPS) vessels targeting tropical tuna species (skipjack, yellowfin, and bigeye), with a combined fishing capacity of over 860,000 m3. The increase is not all due to new vessel constructions, but also to the addition to RFMO lists of older vessels that were not listed in the past. These vessels may have been inactive for some time or participating in a different fishery, but this type of information is not readily available.

Other report findings about the large-scale purse seine vessels targeting tropical tuna include:

  • About 18 percent of the 686 large-scale vessels are authorized to fish in more than one RFMO.
  • About 2 percent of these vessels changed flags in the last year.
  • Among the RFMOs, the Western and Central Pacific Fisheries Commission (WCPFC) still has the highest number of LSPS registrations (347), more than half of the total worldwide.
  • The majority of large-scale vessels (515) are registered on the ISSF ProActive Vessel Register (PVR); PVR-registered LSPS represent 75 percent in number and 83 percent in fish hold volume (FHV).

In addition, the report shows that 97 percent of the large-scale tropical tuna purse seiners operating today have publicly known International Maritime Organization (IMO) numbers; in 2011, that figure was 12 percent. Nearly 100 percent of the purse seine vessels listed on PVR have IMO numbers. ISSF has long recommended in its RFMO advocacy positions and in Conservation Measures 4.1 and 4.2 that vessels obtain IMO numbers, identifiers that do not change even if the vessel ownership, national registration, or name changes. Unique vessel identifiers (UVIs) like IMO numbers are an important tool to combat illegal, unreported and unregulated (IUU) fishing. 

The report also covers purse-seine vessel construction, distribution, and FHV by national flag. It offers recommendations for vessel owners on registration and for RFMOs on vessel-data collection and management. View the updated report here.

International Workshop on Mitigating Environmental Impacts of Tropical Tuna Purse Seine Fisheries

ISSF and the Common Oceans ABNJ Tuna Project co-sponsored the workshop held at the Food and Agriculture Organization of the United Nations’ (FAO) Headquarters in March 2019. The workshop reviewed the progress cross-sector research and advocacy efforts have made in reducing bycatch and other environmental impacts and identified main focus areas for future activities. This video offers a brief overview of the workshop and interviews with attendees.

Improved Monitoring, Reduced Fishing Pressure and Strengthened FAD Management Needed for Sustainable Eastern Pacific Ocean Tuna Fisheries

The International Seafood Sustainability Foundation (ISSF) released its position statement in for the 94th Meeting of the Inter-American Tropical Tuna Commission (IATTC) in Bilbao, Spain, from July 22-26, 2019.

“The Commission took some important steps last year, including the adoption of a technical definition for non-entangling FAD designs, a binding measure on safety at sea for human observers and to require International Maritime Organization (IMO) numbers on all fishing vessels greater than 12m,” said ISSF President Susan Jackson. “However there were many important issues left unresolved and these must be urgently addressed this year.”

Our position statement for #IATTC outlines priority topics for the Commission's meeting this week. Share on X

As top priorities, ISSF urges IATTC to:

  1. Develop a set of options to limit fishing pressure by the purse seine fleet, such as limiting fish aggregating device (FAD) deployments, further limiting the number of active FADs per vessel, and/or limiting the number of all set types.
  2. Strengthen FAD management through science-based measures, including a transition to FADs that do not use nets, and to encouraging the provision of echo-sounder data for scientific purposes.
  3. Fund knowledge-sharing, capacity-building and communication of scientific advice, including the establishment of a scientist-manager dialogue process and the development of harvest strategies for all key tuna species.
  4. Require 100% observer coverage (human or electronic) for longline vessels, small class purse seine vessels and all vessels engaged in at-sea transshipment within five years, and develop minimum electronic monitoring and reporting standards.
  5. Adopt measures to mitigate the incidental catch and maximize post-release survival of sharks, mobulid rays and sea turtles, and require all sharks be landed with fins naturally attached.
  6. Strengthen the IATTC compliance assessment process.
