Bumble Bee: Trump’s tuna tariffs ‘devastating’ for firm

September 21, 2018 — US tuna canning company Bumble Bee Foods warned the US Trade Representative (USTR) in a letter that the now-confirmed tariffs against imports of Chinese tuna would be “devastating” for the firm.

The tariffs — which will come into play on Sept. 24 at 10%, and then go to 25% on Jan. 1, 2019 — will hit US imports of yellowfin, skipjack, and albacore tuna loins, all of which are required by Bumble Bee’s Santa Fe Springs, California factory, wrote CEO Jan Tharp.

The tariffs, which were initially proposed by USTR on July 10, will hike the cost of raw materials, which in turn will “certainly lead to higher prices for US consumers”, Bumble Bee’s leader said.

“We are very concerned with the proposed tariff on tuna loins and the impact that these tariffs will have on our supply chain, global competitiveness, and US operations,” Tharp said. “The proposed tariff on tuna loins will have a devastating effect on Bumble Bee given that our business model is to import tuna loins for further processing and canning in the US by American workers.”

AP Investigation into Sea to Table Raises Questions

July 3, 2018 –On June 15th, the Associated Press released an investigation into Sea to Table, a seafood distributor based in New York, claiming that Sea to Table had misrepresented where some of their seafood had been caught. This case of seafood fraud is particularly troubling as Sea to Table’s main appeal is that they ensure traceability and a clean, sustainable supply chain.

Sea to Table works like this:

Sea to Table partners with domestic fishers, fishing boats, docks, and suppliers to connect them directly to restaurants. Once landed & processed, fish are shipped directly to the chefs who purchase, all facilitated by Sea to Table. This cuts out the traditional fish monger middleman, ensuring a higher price for the fishers and processors, and a fresh, high-quality seafood product for chefs. It also reduces the chances of a fish being mislabeled as the more often a fish changes hands, the more likely it is to be mislabeled.

Encyclopedia Brown and The Case of the Yellowfin Tuna

Sea to Table was a rapidly growing company until the Associated Press found that they sold yellowfin tuna—claimed to be caught off Montauk, NY—that may have been landed elsewhere. The problem comes from one of Sea to Table’s supply partners, Gosman’s, located in Montauk. According to Sea to Table, the tuna sold was supplied by Gosman’s, but had actually been caught in North Carolina (still a sustainable, U.S. fishery). Sea to Table says labeling that tuna as caught off Montauk instead of North Carolina was a simple failure to communicate (and they have apologized), however, the AP did preliminary DNA testing on a piece of tuna in question and claim it is actually from the Indian or Pacific Ocean.

Your Poke Addiction Won’t Drive Tuna Extinct

June 22, 2018 — The hotel where I stayed in London last week has a restaurant that specializes in poke, the Hawaiian dish featuring chunks of raw fish atop of a bed of rice and vegetables. A couple of blocks away, in the restaurant arcade under the new Bloomberg building, I encountered a branch of Ahi Poke, a five-location London chain.

I first ate poke in Los Angeles in the summer of 2015, as it took Southern California by storm. Not long afterward, it conquered New York. By late 2016, Nation’s Restaurant News was proclaiming that “poke is sweeping the nation.” Now it appears to be sweeping yet another nation.

And so, as I consumed an Oahu bowl at Ahi Poke one day last week, I started wondering whether there are enough fish in the sea to survive this globalization of poke. I am not the first to wonder this. LA Weekly ran an April Fools’ spoof last year headlined “L.A. Poke Joints Shutter as Ocean Officially Runs Out of Fish.” Hawaii-based journalist Jennifer Fiedler took a more serious look in an extensively reported 2016 article for New York magazine’s Grub Street site, although she wasn’t able to answer the question definitively. I won’t be able to answer it definitively, either, but I can at least take a couple more steps in that direction, plus share some cool charts.

The main fish of concern here is the yellowfin tuna (scientific name: Thunnus albacares), which is almost certainly what was in my Oahu bowl. Poke restaurants outside of Hawaii also serve a lot of raw salmon, but the overwhelming majority of commercially available salmon is farmed, and while there are environmental concerns about some salmon-farming practices, we do not seem to be in any danger of running out of the fishies.

The quintessential poke fish, though, is ahi tuna, and it’s all wild-caught. In Hawaii, ahi originally meant bigeye tuna (Thunnus obesus), but yellowfin now gets the name, too. With the global yellowfin catch almost four times bigger than the bigeye catch, and the price lower, the ahi you eat in your poke is generally going to be yellowfin.

AP report claims Sea To Table lied to customers about seafood origins

June 14, 2018 — An investigative report by the Associated Press claims it has found evidence that the company Sea To Table has been misleading customers about origins of its seafood.

Sea To Table, founded more than two decades ago, offers fresh wild-caught seafood sourced from small-scale American fishermen. The company guarantees that its products are wild-caught and directly traceable to docks, and often specific boats, in the U.S. The purchase of the seafood often comes with informational packages detailing the origins and the people behind the product.

According to the AP report, published on 13 June, those claims may be suspect as investigations found that the company was sourcing “fresh” seafood from boats that hadn’t been to sea for two years, species that weren’t allowed to be fished in locations Sea To Table was claiming they were from, and tuna from southeast Asian companies with checkered histories of labor abuse.

“Preliminary DNA tests suggested some of its yellowfin tuna likely came from the other side of the world, and reporters traced the company’s supply chain to migrant fishermen in foreign waters who described labor abuses, poaching and the slaughter of sharks, whales and dolphins,” the AP report said.

ISSF Releases Interactive “Status of the Stocks Tool”

April 5, 2018 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

The International Seafood Sustainability Foundation (ISSF) has developed a new data-visualization tool based on its long-running and widely followed Status of the Stocks report. The “Status of the Stocks 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.

The tool, which requires no additional applications or access to use, offers fisheries managers, fishers, RFMOs, scientists, and other stakeholders a convenient and intuitive resource for visualizing the state of tuna stocks worldwide, covering 23 tuna stocks — including ones that have been or are overfished, as well as those at healthy levels. Offering the most current data available, it also pulls information from previous years of ISSF Status of the Stocks reports, which compile key stock health and catch data from the Regional Fisheries Management Organizations (RFMOs).

“As part of our ongoing efforts to bring improved technology into understanding fisheries management, we developed this resource to offer a clearer picture of trends in global tuna stock health over time,” said ISSF President Susan Jackson. “Not only does a data visualization tool such as this allow users a customized look at the tuna stocks they are most interested in, it also offers a meaningful understanding of the impact of changes in RFMO management on those tuna stocks over time.”

For example, the number of stocks well-managed in terms of fishing mortality has increased from 8 (35%) in 2012 to 15 (65%) in 2018, demonstrating the improvement of management measures put in place by the RFMOs. Improved management measures lead to stock rebuilding, as in the case of bluefin tuna stocks, where 100% of the catch came from overfished stocks in 2013, versus just 26.5% of the catch in 2018. The tool can also be used to monitor those stocks for which management has been effective and, therefore, resulted in maintained healthy levels of abundance over time (e.g., skipjack stocks).

The tool was developed by ISSF’s science and communications teams and was reviewed by the scientists on the ISSF Scientific Advisory Committee.

Interactive Tool Design

The tool, built using Tableau technology, features two tabs — one for visualizing tuna stock health trends since 2011, and another for visualizing the recent tuna catch by fishing method.

Users can generate a variety of customized and exportable graphics within the tool based on the parameters they choose in the checkboxes (such as “ocean location”) or buttons. By hovering or clicking on the graphics, users can see percentages and other details.

On the Stock Health tab, data can be filtered first by tuna species and ocean region. The user can choose between visualizing data relative to total catch or to number of stocks, and between ratings on stock abundance or on fishing mortality. As a result, the corresponding area graph is generated. Like the Status of the Stocks reports, the tool uses a color rating system: green (“healthy”), yellow (“intermediate”), and orange (“needs improvement”).

The Catch tab currently features data from 2016, the most recent year for which complete catch data are available. Gear type data can be filtered by ocean location to generate a bar chart.

ISSF’s “Status of the Stocks Tool” will be updated as new iterations of the Status of the Stocks Reportare released. To access the most recent Status of the Stocks report in full, click here.

About the ISSF 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. This report ranks the status and management of the 23 stocks using a consistent methodology based on three factors: Abundance, Exploitation/Management (fishing mortality) and Environmental Impact (bycatch).

ISSF also produces a complementary report, the Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria (MSC) which provides scores for the stocks and RFMOs based on MSC assessment criteria. The MSC-certified fisheries list (Appendix 2) inStatus 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. Access the newly updated ISSF stock status ratings here.

State of Tuna Stocks Worldwide Assessed in Comprehensive ISSF Report

Global tuna catch stays at 78% healthy level

March 8, 2018 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

Of the total tuna catch in 2016, 78% came from stocks at “healthy” levels, unchanged since last reported, according to a February 2018 International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. Skipjack tuna stocks — at healthy levels in all ocean regions — constituted more than one-half of the 2016 total catch.

One notable change in stock status in the February 2018 Status report is for Southern bluefin tuna, a stock that has moved from orange to yellow in abundance ratings. Stock abundance is low, about 13% of the unfished level. However, the stock is rebuilding continuously as a result of the implementation of a robust Management Procedure (a Harvest Strategy) by the Commission for the Conservation of Southern Bluefin Tuna, the regional organization in charge of managing the stock. In contrast, the Pacific bluefin stock, along with the Indian Ocean yellowfin stock and the Atlantic Ocean bigeye stock remain overfished. See Tables 1 and 2 in the report for specific rating changes.

There were no dramatic changes in tuna stock status since the previous November 2017 Status report; the updated report reflects new data made available at late 2017 tuna Regional Fisheries Management Organization (RFMO) meetings.

Updated several times per year, Status of the Stocks assigns color ratings (green, yellow or orange) on stock heath, stock management, and ecosystem impact. The report ranks the 23 stocks of major commercial tunas around the world using a consistent methodology.

Key Statistics in the Report

  • Total catch: In 2016, the total major commercial tuna catch was 4.9 million tonnes, a 2% increase from 2015. More than half of the total catch (57%) was skipjack tuna, followed by yellowfin (30%), bigeye (8%) and albacore (4%). Bluefin tunas (3 species) accounted for only 1% of the global catch. These percentages changed only slightly from the Nov. 2017 reporting period. 
  • Abundance or “spawning biomass” levels: Globally, 57% of the 23 stocks are at a healthy level of abundance, 13% are overfished, and 30% are at an intermediate level.
  • Stocks receiving orange scores, indicating overfished status, include Atlantic Ocean bigeye, Pacific Ocean bluefin and Indian Ocean yellowfin.
  • Fishing mortality levels: 65% of the 23 stocks are experiencing a well-managed fishing mortality rate, and 13% are experiencing overfishing (with no change from the previous report).
  • Largest catches by stock: The three largest catches in tonnes are Western Pacific Ocean skipjack, Western Pacific Ocean yellowfin, and Indian Ocean skipjack.
  • Tuna production by ocean region: Most (53%) 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 (10%).
  • Tuna production by fishing gear: 65% of the catch is made by purse seining, followed by longline (12%), pole-and-line (8%), gillnets (3%) and miscellaneous gears (12%). These percentages changed only slightly from the Nov. 2017 reporting 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. This report ranks the status and management of the 23 stocks 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 Criteria (MSC) provides scores for the stocks and RFMOs based on MSC assessment criteria.

ISSF Report Shows Management of Many Tuna Stocks Not Meeting Criteria for Marine Stewardship Council (MSC) Sustainability Standards

January 11, 2018 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

Only six out of 19 major commercial tuna stocks are being managed to avoid overfishing and restore depleted fish populations because the majority of the stocks are not protected by well-defined harvest control rules (HCRs) from Regional Fishing Management Organizations (RFMOs), according to independent scientists in a report published by the International Seafood Sustainability Foundation (ISSF).

ISSF 2017-09: An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria finds that, while there has been progress by RFMOs towards developing harvest strategies and implementing well-defined harvest control rules, failure to implement controls for stocks before rebuilding is required has led to an inability to meet the MSC standard’s minimum requirements on harvest control rules.

In the December 2016 version of the report, almost twice as many stocks — 11 of 19 — were found to be well managed. This variance can be attributed in part to refinements made in 2017 regarding how the MSC standard assesses harvest control rules. The authors note, “Scoring guideposts were changed and additional guidance was provided to interpret the scoring guidepost text. The objective of these changes was not to alter the standard, but to continue to improve consistency in its definition and application across the wide variety of fisheries that are seeking certification.”

The report also notes an improvement in stock status scores (PI 1.1.1). For a visual summary of changes over time in the report’s scores, please see related infographics on the ISSF website:Summary of Sustainable Tuna Stocks (MSC Principle 1) and RFMO Performance (MSC Principle 3 Averages).

About the Report
An Evaluation of the Sustainability of Global Tuna Stocks takes a consistent, comprehensive approach to scoring stocks against certain components of the Marine Stewardship Council (MSC) standard. The MSC is a global certification program for fisheries.

The report — updated three times since 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 four RFMOs, and comprehensive reference citations.

Additional Report Findings

The report scores the main commercial tuna stocks (bigeye, yellowfin, albacore, and skipjack — but not bluefin) and each tuna RFMO (ICCAT, IATTC, WCPFC, and IOTC). An 80 is a passing score, below 60 is a failing score, and 60–79 would indicate a conditional pass, with the requirement that any deficiency is addressed within five years if a fishery were to become MSC-certified.

Other findings for each principle are as follows:

MSC Principle 1
The MSC’s 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.”

Regarding stocks receiving passing scores:

  • Among seven tuna stocks in the Atlantic Ocean, two received an overall principle-level passing score: Yellowfin and Northern Albacore, which “has recovered from biomass reductions several decades ago”
  • Western Pacific Skipjack, Eastern Pacific Yellowfin, Eastern Pacific Bigeye, and Indian Ocean Skipjack all received principle-level passing scores.

In contrast, regarding stocks receiving failing scores:

  • In the Pacific, four stocks received overall principle-level failing scores: Western Yellowfin; North Albacore, South Albacore, and Western Bigeye, which has been undergoing a steady decline since the 1970s.
  • Likewise, in the Indian Ocean, Yellowfin, Bigeye, and Albacore all received overall principle-level failing scores.
  • Yellowfin stocks in the Atlantic and Indian Oceans require rebuilding, as does Atlantic Bigeye.
  • Mediterranean Albacore and Indian Ocean Yellowfin had the most failing scores on individual performance indicators — including on stock rebuilding, harvest strategies and harvest control rules and tools. 

MSC Principle 3
The MSC’s 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.”

  • Two RFMOs — WCPFC and IATTC — received passing scores for all seven performance indicators under Principle 3.
  • The other two RFMOs — ICCAT and IOTC — received conditional passing scores on two performance indicators: “consultation, roles and responsibilities” and “compliance and enforcement.” ICCAT was given a conditional pass score for “legal and customary framework.” Other performance indicators include “long term objectives”; “fishery specific objectives”; “decision-making processes”; and “management performance evaluation.”
  • All four 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 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.

WCPFC members agree to increase bigeye limits

December 8, 2017 — Members of the Western and Central Pacific Fisheries Commission concluded a five-day conference in Manilla, The Philippines, earlier this week by increasing catch limits on tropical tunas. It’s a move at least one conservation group fears could threaten the bigeye stock.

Beginning next year, Japan will be able to catch up to 18,265 metric tons of bigeye tuna. South Korea was allotted a nearly 14,000-metric-ton limit, while Taiwan will be able to harvest nearly 10,500 metric tons. China received a limit of more than 8,200 metric tons, in addition to a one-time transfer of 500 metric tons from Japan in 2018. Indonesia received a provisional allotment of nearly 5,900 metric tons, and the United States, which won the right to use its Pacific territories to increase its limit, can catch more than 3,500 metric tons.

Those limits were set after the commission’s scientific committee concluded that the bigeye stock “appears” not to suffer from overfishing.

Amanda Nickson, who is the director of international fisheries for The Pew Charitable Trusts, called the decision to increase the limits by 10 percent disappointing. The commission’s decisions mean the bigeye stock have a greater than 20 percent chance of falling below its accepted biomass standards over the next 30 years.

ISSF Position Statement Calls for Better Management of Stocks and Non-entangling FAD Requirements in Western and Central Pacific Ocean (WCPO)

December 4, 2017 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation: 

Reducing catches of yellowfin and bigeye tuna and adoption of a non-entangling FAD measure are among the changes advocated for Western and Central Pacific Ocean (WCPO) fisheries by the International Seafood Sustainability Foundation (ISSF) in a position statement submitted for the 14th Regular Session Meeting of the Western and Central Pacific Fisheries Commission (WCPFC) in Manila, Philippines, on December 3-7.

The WCPFC, which oversees tuna stocks in the WCPO, is one of five tuna Regional Fishing Management Organizations (RFMOs). “As the region responsible for more than 60 percent of the global tuna catch, the Western and Central Pacific holds significant responsibility for the sustainable management of global tuna resources,” said ISSF President Susan Jackson. “But the region is not only a leader in tuna catches. It has also shown leadership in sustainability efforts to ensure that the fishery is properly managed and protected.

“While ISSF recognizes this leadership, there is still much work to do in the region, especially with regards to addressing the stock status of yellowfin and bigeye tuna and catching up to their tuna RFMO counterparts by adopting a measure for the use of non-entangling FAD designs.”

Tuna Conservation
While the results of 2017 WCPO bigeye stock assessment were more positive than in recent years, ISSF believes active management needs to continue because there is still a good chance that the stock is below the adopted Limit Reference Point (LRP). Further, the WCPFC Scientific Committee advised that— due to the inclusion of new information on bigeye growth and regional structures—the amount of uncertainty in the stock status results for the 2017 assessment is higher than for the previous assessment.

The 2017 yellowfin assessment indicates that the stock is not overfished or being overfished, but ISSF strongly believes that given uncertainties, the WCPFC should be precautionary and not allow the yellowfin catch rate to increase. 

FAD Management and Non-Entangling FAD Designs

Greater data collection is needed on the number of FADs being used and the details of fishing operations on individual FADs in order to better understand fishing capacity changes and likely impacts on WCPFC-managed stocks. That data should then be used to develop science-based FAD management measures.  

Jackson continued, “In the WCPO, FAD sets account for about 30 percent of tropical tuna catches. There is a need globally for measures that help better monitor and manage FAD usage in every ocean region. Shark mortality and other FAD-fishing ecosystem impacts in the WCPO also have to be addressed, for which the wide-scale adoption of non-entangling FAD designs is a critical step.”

Longline Observer Coverage

Comprehensive observer coverage is a critical component of monitoring and management for sustainable tropical tuna fisheries. For large-scale purse seiners, WCPFC implemented a 100 percent observer coverage requirement; the requirement for longline fisheries is only a minimum of 5 percent. The science committees for two other tuna RFMOs have recommended 20 percent longline observer coverage, a level appropriate to provide reasonable estimates of total bycatch. If human onboard observers are not possible for certain fleets or vessel sizes, including longliners, then guidelines for using electronic monitoring should be adopted. ISSF is pleased that in 2016, the WCPFC adopted operational logsheet data standards for electronic reporting and made progress in developing electronic reporting observer data standards.

ISSF is asking WCPFC to increase its observer coverage standards to 20 percent and to finalize the development of the electronic monitoring and reporting standards so that such tools can be used to achieve 100% observer coverage in the longline fishery.

Other priority improvements in the ISSF position statement include:

  • Adhere to the updated 2015 harvest strategy work plan and take the decisions necessary this year (e.g., a target reference point for yellowfin tuna and South Pacific albacore, and development of harvest control rules for skipjack, bigeye, South Pacific albacore and yellowfin tuna).
  • Reform the compliance assessment process to allow accredited observer participation.
  • Amend the transshipment measure in order to address gaps in its effectiveness due to lack of required reporting or advanced notifications.
  • Strengthen shark conservation and management by prohibiting the use of shark lines; adopt scientists’ recommended Shark Research Plan and future work plan and the safe release guidelines for rays; adopt a measure to require that sharks be landed with fins still naturally attached to improve compliance and species specific data collection; and direct the Scientific Committee to develop guidelines for the safe release of silky and oceanic whitetip sharks.

Updated ISSF Status of the Stocks Report Shows Tuna Stock Abundance and Fishing Mortality Improvements

November 2, 2017 — WASHINGTON — The following was released  by the International Seafood Sustainability Foundation:

Of the total tuna catch, 78% comes from stocks at “healthy” levels, an increase of 2% since last reported, according to a November 2017 International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. Eleven percent of the global catch came from overfished stocks, and another 11% of the catch is from stocks at an intermediate level of abundance. (See “Key Questions” below for definitions of overfished and overfishing.)

Updated several times per year, Status of the Stocks ranks the 23 stocks of major commercial tunas around the world using a consistent methodology. The report assigns color ratings (green, yellow or orange) on stock health, alternately noted as “abundance” and “spawning biomass”; fishing mortality; and ecosystem impact.

There are some encouraging changes in tuna stock status since the previous February 2017 Status report. The November 2017 report reflects new data from 2017 tuna Regional Fisheries Management Organization (RFMO) meetings:

  • Abundance ratings improved for Eastern Pacific bigeye, Western and Central Pacific bigeye, Mediterranean albacore, and Western Atlantic bluefin.
  • Fishing mortality ratings improved for Western and Central Pacific bigeye, North Pacific albacore, and Indian Ocean albacore.

In contrast, two bluefin stocks (Southern and Pacific Ocean), one yellowfin stock (Indian Ocean), and one bigeye stock (Atlantic Ocean) remain overfished. See Tables 1 and 2 in the report for specific rating changes.

Inadequate bycatch monitoring and/or bycatch mitigation measures — represented by separate “Environmental Impact” scores, the third rating area — still are a concern in many of the tuna fisheries studied.


Key Findings in Updated Report
Other notable statistics and findings include:

  • Total catch: In 2015, the total major commercial tuna catch was 4.8 million tonnes, a 4% decrease from 2014. More than half of the total catch (58%) was skipjack tuna, followed by yellowfin (28%), bigeye (8%) and albacore (4%). Bluefin tunas accounted for only 1% of the global catch. These percentages did not change from the February 2017 report.
  • Abundance or “spawning biomass” levels: Globally, 57% of the 23 stocks are at a healthy level of abundance (an increase of 5% from the previous report), 17% are overfished, and 26% are at an intermediate level.
    • Stocks receiving orange scores, indicating overfishing or overfished status, include both Southern Hemisphere and Pacific Ocean bluefin, Indian Ocean yellowfin, and Atlantic bigeye.
  • Fishing mortality levels: 65% of the stocks (an 8% improvement since the previous report) are experiencing a low fishing mortality rate, and 13% are experiencing overfishing.
  • Largest catches by stock: The three largest catches in tonnes are Western Pacific Ocean skipjack, Western Pacific Ocean yellowfin, and Indian Ocean yellowfin.
  • Tuna production by fishing gear: 64% of the catch is made by purse seining, followed by longline (12%), pole-and-line (9%), gillnets (4%) and miscellaneous gears (11%).

For the first time in Status of the Stocks history, the November 2017 report features an appendix with a list of fisheries certified by the Marine Stewardship Council (MSC).

“The MSC fishery certification scheme is the most widely recognized indicator of seafood sustainability,” explains Dr. Victor Restrepo, Vice President of Science, ISSF. “The list helps us to track the tuna stocks and fishing gears that are certified.”

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. In addition, this report ranks the status and management of the 23 stocks 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 Criteria provides a review of the health of tuna fisheries by region. 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. Access the newly updated ISSF stock status ratings here.

Key Questions Answered by the Report
Status of the Stocks answers three key questions about each tuna stock:

  1. Is the stock overfished?
    A. The report measures the abundance of fish that are able to reproduce each year, called the spawning stock biomass (SSB), and compares it to an estimate of the biomass that would produce maximum sustainable yield (SSBMSY), which is the spawning biomass that results in the highest average catches in the long-term (this is a target of fisheries management). When SSB is below SSBMSY the stock is in an “overfished” state.

Overfishing doesn’t necessarily mean that the stock is in immediate danger of extinction or collapse — it means that currently, the fish aren’t being allowed to grow and reproduce at their most productive level. If a stock is overfished, the report will note any corrective measures being taken by the relevant fisheries management organization (RFMO).

  1. Is it in danger of becoming overfished?
  2. The report measures the fishing mortality rate (F), a measure of fishing intensity, and compares it to the fishing mortality that produces maximum sustainable yield (FMSY). When F is above FMSY, the stock is in danger of becoming overfished in the future. This is called overfishing. If overfishing is taking place, the report will note any corrective measures being taken.
  3. Are the methods used to catch the tuna also catching significant numbers of non-targeted species?
  4. The report also measures the environmental impact of fishing in terms of “bycatch” rates. Bycatch is any species caught by the boat that is not the kind of fish the skipper is searching for. All fishing methods result in some bycatch of non-target species. The report identifies the relative bycatch rates by fishing gear and reports on mitigation measures adopted by the RFMOs for various species groups.
