Japan to Propose Bluefin Tuna Catch Quota Increase At WCPFC Meeting

August 2, 2018 — SEAFOOD NEWS — The government plans to propose raising catch quotas for Pacific bluefin tuna — a popular component of high-grade sushi — in September, following an international body’s recent estimate that it is feasible to increase catches by up to about 15 percent from 2019, thanks to a recovery in the stock.

Overfishing has drastically declined bluefin stock to about 10 percent of its peak level of 168,125 tons in 1961. Since 2015, the Western and Central Pacific Fisheries Commission has set caps on catches to strengthen the management of the resource. The commission has 26 member countries and regions, including Japan and the United States.

The WCPFC has set a mid-term target of increasing stocks of adult Pacific bluefin tuna weighing 30 kilograms or more, from the latest estimate of about 21,000 tons to 43,000 tons in 2024. At the same time, the commission has adopted a policy of allowing higher catch quotas once the probability of achieving the target reaches 70 percent or more.

An international organization comprising experts in such fields as fishery survey announced in mid-July that the probability of achieving the target would be 74 percent if total catches — which combine small-sized fish weighing less than 30 kilograms and large ones of 30 kilograms or larger — increase by 15 percent from 2019.

This has led Tokyo to plan to propose increasing catch quotas at a September committee meeting of the WCPFC in Fukuoka Prefecture, in the hope of obtaining understanding from respective countries and regions. The government is working out details of the proposal, such as a specific increase in catch quotas for both small and adult fish.

Bluefin tuna caught in the Pacific Ocean accounts for 60 percent of the Japan market. The nation’s catch quota is set at 4,007 tons for small fish — about half of the average in previous years — and 4,882 tons for adult fish, which is equivalent to this category’s average.

Atlantic bluefin tuna stocks have also plunged due to overfishing, but strict regulations — such as prohibiting fishing small ones in principle — have subsequently been successful, resulting in a decision to raise catch quotas.

Conservation groups disagree with NOAA decision on Western Atlantic bluefin

May 22, 2018 — The decision by NOAA Fisheries to remove Western Atlantic bluefin tuna is not sitting well with conservationists.

Last week, the agency released its Status of U.S. Fisheries report for 2017. In it, officials announced that the number of stocks on the overfished list had dropped to 35, an all-time low. The Western Atlantic bluefin was among six stocks removed from the overfished list. NOAA, in a press release, said “significant scientific uncertainty” about the stock after last year’s assessment led to the ruling.

To be placed on the overfished list, NOAA officials must determine the stock’s population is too small. That differs from the overfishing list, where stocks with an excessive catch rate land. Overfished stocks may not necessarily be subject to overfishing currently, however, the stock cannot produce a maximum sustainable yield in its present condition. Other factors, such as environmental changes, also may put a stock on the overfished list.

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.

Climate change threatens coastal life as we know it

March 9, 2018 — The Gulf of Maine is getting warm — quick. From 2004–2013, sea temperatures there rose faster than almost any other location on Earth.

Why it matters: The Gulf is home to a number of endangered species, and the fisheries there bring in several billion dollars per year to the U.S. and Canada, but the Gulf’s future hangs in the balance. Researchers are scrambling to understand what the warming water means for the people and animals who rely on the ecosystem, particularly as the changes there provide a glimpse into the future of coastlines around the world.

Why it’s warming

The Gulf of Maine lies at the intersection of several major ocean currents, including the Atlantic meridional overturning circulation, which moves dense, cold water down and toward the equator. Fresh water from melting sea ice seems to be weakening this current, which could be causing the Gulf to warm faster than other regions.

A combination of cold winters, warm summers, and dramatic tides make the Gulf one of the most productive ecosystems in the ocean. It’s a critical habitat for right whales, seabirds like puffins, humpback whales, bluefin tuna and other species.

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

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. 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.

Climate change draws invasive species to the Arctic

February 27, 2018 — The Arctic is changing. Temperatures are increasing twice as fast as the global average and sea ice is retreating quicker than predicted.

It is now just a question of time before the Arctic becomes ice free in summer.

But while we humans react slowly to the problem at hand, evidence suggests that animals are on the move- on land, sea, and in the air. And in the cold Arctic, invasive species are drawn to regions where they could not previously have survived.

But invasive species pose a big problem for native animals, whose numbers can decline to the point of collapse. They also pose a threat to fisheries, with economic consequences on both a local and global scale.

In fact, our recent study showed that blue mussels have become much more common in the Arctic in recent years, just like other exotic species of bluefin tuna and killer whales.

$300K Tuna Sold at Final Tsukiji Fish Market Heads to NYC Sushi Chain

January 19, 2018 — SEAFOOD NEWS — The 890 lb. bluefin tuna sold for $323,195 at the final New Year’s auction at Tokyo’s famed Tsukiji fish market has made its way to New York City.

The fish was bought by the Onodera Group, which has 11 restaurants in seven cities around the world, including London, Paris, Shanghai and Los Angeles. Sushi Ginza Onodera, located on 5th Avenue in New York City, is the lucky restaurant to score the fish for its diners. This week they’re serving sushi made from the massive bluefin tuna – and at no extra charge. However, there is a catch. The restaurant only offers its sushi in an “omakase setting,” which means that the course selection is in the hands of the chef. And it can get pricey. While the restaurant does not list prices online, guests on yelp say that lunch can range from $100 to $150 per person, while dinner can reach $400 per person.

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.

Pacific Bluefin Tuna Catch Quotas to be Based on Stock Recovery

December 12, 2017 — TOKYO, SEAFOOD NEWS — An international panel has decided to introduce a new framework to change catch quotas for Pacific bluefin tuna according to the extent of stock recovery.

The Western and Central Pacific Fisheries Commission made the decision at its annual meeting in Manila, which ended early Friday.

The WCPFC, which discusses resources management for tuna and bonito in the Western and Central Pacific, has 26 member economies, including Japan, the United States and China.

The panel has set a goal of increasing adult Pacific bluefin tuna stocks from some 17,000 tons in 2014 to around 41,000 tons by 2024.

In September, the WCPFC’s Northern Committee agreed to increase catch quotas once the probability of achieving the goal reaches 75 pct or more and to reduce the quotas if the figure falls below 60 pct.

With the WCPFC approving the introduction of the new rules, the framework to change catch quotas according to the speed of stock recovery is expected to be put in place in 2019 at the earliest.

ICCAT decision to raise bluefin quotas draws scrutiny

November 24, 2017 — Conservation groups reacted with outrage after the International Commission for the Conservation of Atlantic Tunas (ICCAT) concluded its annual conference, as the member nations decided to increase catch limits on bluefin tuna.

ICCAT’s decision to raise eastern Atlantic and Mediterranean bluefin limits to 36,000 tons by 2020 represents a 50 percent increase from current levels. The move prompted fears the species that was threatened due to years of overfishing may face peril yet again, according to Alessandro Buzzi, a WWF fisheries project manager.

“We have been fighting for the last 10 years to save bluefin tuna, we are so near recovery that it is a scandal to see ICCAT going back to business as usual; this could jeopardize all the progress we’ve made,” Buzzi said.

In a statement, the commission said it was following the advice of its scientific committee to grant the “considerable” increase. The limit will be raised gradually over the next three years, with next year’s limit set at 28,200 tons.

In addition, a tentative agreement on next year’s quota share was reached, with discussions on future years set to take place in March.

“While a larger pie to share should have led to greater possibilities of consensus, the demands by those who already had a quota for a larger slice made negotiations tougher than ever,” the commission said.

Officials with The Pew Charitable Trusts said the decisions made during the conference were among the “poorest” in a long time.
