Fisheries Research Must Go On

Fisheries scientists, like almost everyone else, were forced to accept a new normal during the global pandemic. We found ourselves sharing workspaces with our remote-learning children. Traveling much less often, as movement restrictions rendered certain projects downright unfeasible. And collaborating with colleagues virtually, rather than face-to-face—which meant missing some critically productive (and usually enjoyable) aspects of our work. But sustainability couldn’t wait for the old normal to return. We had to keep progressing, one way or another.

Some of our most exciting work is centered on “jelly-FADs”—biodegradable fish aggregating devices (FADs) that we designed in collaboration with a team of physical oceanographers. Jelly-FADs are made of organic materials and are smaller than traditional models, yet they drift slowly, like jellyfish, so ocean currents are less likely to carry them too far afield. Both of those qualities will reduce their environmental impact if they are lost or abandoned.

ICYMI: 87.7% of Global Tuna Catch Continues to Come from Stocks at Healthy Levels; 9.6% Require Stronger Management

Of the total commercial tuna catch worldwide, 87.7% of the global catch continues to be sourced from stocks at “healthy” levels of abundance, according to the newest International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. In addition, 9.6% of the total tuna catch came from overfished stocks, and 2.7% came from stocks at an intermediate level of abundance.

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

ICYMI: Action Needed to Protect Eastern Pacific Ocean Tuna Stocks

The August 2021 Inter-American Tropical Tuna Commission (IATTC) annual meeting yielded few positive results in advancing the Commission’s agenda to protect bigeye, yellowfin and skipjack tuna stocks in the Eastern Pacific Ocean.

ISSF issued a position statement before the meeting calling for the adoption of a precautionary and science-based new version of the current inadequate IATTC conservation measure. And ISSF President Susan Jackson noted, “Decisive action on these items in August will clear the way for an October agenda that is set up for progress on other pressing topics like harvest strategies and monitoring, control, and surveillance. The added fall IATTC meeting must be viewed as further opportunity to adopt all much-needed measures before the end of the year—rather than a reason to delay decision-making at the August meeting.”

Unfortunately, the IATTC was unable to reach a consensus on a tuna conservation measure, delaying this critical goal until part two of its annual meeting next week. ISSF is therefore urging all IATTC parties to come to the first day of the meeting ready to adopt a new tropical tuna measure — allowing adequate time to address the other critical matters before the Commission this year.

Questions and Answers About FADs & Bycatch

How does the bycatch of non-target species in purse seine fisheries compare to other major global fisheries?

Do sets on FADs and other fishing methods catch juvenile tunas? What are their impacts?

These questions are examples of the many timely inquiries addressed in a newly revised ISSF technical report, Questions and Answers About FADs and Bycatch, co-authored by ISSF scientists Hilario Murua, Ana Justel-Rubio, Gala Moreno and Victor Restrepo, as well as marine scientist Laurent Dagorn. Illustrated throughout with charts and graphics, the report has been updated to reflect the latest tuna fisheries data.

Of the total commercial tuna catch worldwide, 87.7% of the global catch continues to be sourced from stocks at “healthy” levels of abundance, according to the newest International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. In addition, 9.6% of the total tuna catch came from overfished stocks, and 2.7% came from stocks at an intermediate level of abundance.

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

  • The Indian Ocean yellowfin and Pacific bluefin tuna stocks continue to be overfished and subject to overfishing.
  • Atlantic Ocean bigeye status remains overfished and subject to overfishing, although the results of the most recent RFMO Science Committee meeting were not available at the time of writing and will be reflected in the next report update. 
  • Indian Ocean albacore and bigeye continue to be subject to overfishing.

87.7% of Global Tuna Catch Continues to Come from Stocks at Healthy Levels; 9.6% Require Stronger Management

Of the total commercial tuna catch worldwide, 87.7% of the global catch continues to be sourced from stocks at “healthy” levels of abundance, according to the newest International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. In addition, 9.6% of the total tuna catch came from overfished stocks, and 2.7% came from stocks at an intermediate level of abundance. This is the third update to this report since March 2020, when the COVID-19 pandemic started to impact the work of Regional Fisheries Management Organizations (RFMOs). 

Our latest Status of the Stocks analysis shows that several #tuna stocks remain overfished and/or subject to #overfishing. Get the details: Click To Tweet

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

  • The Indian Ocean yellowfin and Pacific bluefin tuna stocks continue to be overfished and subject to overfishing.
  • Atlantic Ocean bigeye status remains overfished and subject to overfishing, although the results of the most recent RFMO Science Committee meeting were not available at the time of writing and will be reflected in the next report update. 
  • Indian Ocean albacore and bigeye continue to be subject to overfishing.
  • All skipjack and most albacore stocks remain healthy.

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, 22% are at an intermediate level, and 13% are overfished.
  • 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 5.3 million tonnes in 2019, a 1% increase from 2018. 60% was skipjack tuna, followed by yellowfin (28%), bigeye (7%), and albacore (4%). Bluefin tuna 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: 65.7% of the catch is made by purse seining, followed by longline (10.0%), pole-and-line (7.8%), gillnets (3.7%), and miscellaneous gears (12.9%). 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 third update to this report since March 2020, when the COVID-19 pandemic began to impact the work of the RFMOs. RFMOs have 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.

The report includes updated catch data and the latest changes to stock status and management as of the end of September 2021. In the time since our March 2020 report, a new stock assessment of South Pacific albacore was completed.

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.

ICYMI: Understanding the IUCN Red List

“In the days since the International Union for Conservation of Nature (IUCN) released its updated Red List of Threatened Species™, many colleagues have contacted ISSF to celebrate IUCN’s news that four tuna species were no longer classified as endangered.

IUCN attributed the progress to countries enforcing sustainable fishing quotas and successfully combating illegal fishing, which are essential for protecting in-demand fish stocks and the marine ecosystem. In noting any improvements in tuna stock health, sustainable fishing stakeholders also should acknowledge successes in implementing needed fisheries management measures by tuna Regional Fisheries Management Organizations…

I welcome attention to the urgency regarding tuna stock sustainability, and I join in the celebration of hard-won gains in tuna conservation. But there is more to the story.”

Dr. Victor Restrepo considers why it’s important to understand how the IUCN Red List methodology compares to other tuna assessment criteria.

NEW REPORT: 1,855 Purse Seine Vessels Authorized to Fish for Tuna

Featured News

Increase in Purse Seine Vessels Overall, but Fewer Large Scale Purse Seine Vessels Fishing for Tropical Tuna Species Globally

The International Seafood Sustainability Foundation (ISSF) has updated its report Large-Scale Tuna Purse Seine Fishing Fleets as of July 2021. The total number of purse seine vessels, calculated based on data from the five tuna Regional Fisheries Management Organizations (RFMOs), has increased from 1,721 in 2020 to 1,855 today. The report also shows approximately 678 vessels (down 2.6 percent from 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 865,000 m3 (cubic meters). 

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 69 percent of the 5.0 million-tonne global tuna catch, multiple databases must be searched to compile a count of 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.

ISSF Study Reports Increase in Purse Seine Vessels Overall, but Fewer Large Scale Purse Seine Vessels Fishing for Tropical Tuna Species Globally

Tuna Conservation Group Releases 2021 Snapshot of Large-Scale Tropical Tuna Purse Seine Fishing Fleets as of July 2021

The International Seafood Sustainability Foundation (ISSF) has updated its Large-Scale Tuna Purse Seine Fishing Fleets report as of July 2021. The total number of purse seine vessels, calculated based on data from the five tuna Regional Fisheries Management Organizations (RFMOs), has increased from 1,721 in 2020 to 1,855 today. 

The report also shows approximately 678 vessels (down 2.6 percent from 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 865,000 m3 (cubic meters). 

In our new report, we calculate there are about 678 large-scale purse-seine vessels targeting tropical #tuna species today, with a combined #fishing #capacity of over 865,000 cubic meters. Click To Tweet

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 69 percent of the 5.0 million-tonne global tuna catch, multiple databases must be searched to compile a count of 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 still 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. 

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

  • About 16 percent of these 678 large-scale vessels are authorized to fish in more than one RFMO, which should be taken into account in any efforts to manage fishing capacity at a regional level.
  • Among the RFMOs, the Western and Central Pacific Fisheries Commission (WCPFC) still has the highest number of LSPS registrations (341), more than half of the total worldwide. 
  • The majority of large-scale vessels (503) are registered on the ISSF ProActive Vessel Register (PVR); PVR-registered LSPS represent 74 percent in number and 81 percent in fish hold volume (FHV).

The report also covers purse-seine vessel construction, distribution, and FHV by national flag. It offers recommendations for vessel owners on registration for IMO numbers and for RFMOs on vessel-data collection and management, such as a recommendation to publish lists of active vessels.
