ISSF to IOTC: Listen to your scientists, take immediate steps to protect Yellowfin

June 13, 2019 — The following was released by the International Seafood Sustainability Foundation:

The International Seafood Sustainability Foundation (ISSF) published its position statement in advance of the 23rd Session of the Indian Ocean Tuna Commission (IOTC)in Hyderabad, India, June 17-21.

ISSF’s highest priority item for IOTC is the adoption of an effective rebuilding plan for yellowfin tuna, one that gives full effect to the recommendations from IOTC’s Scientific Committee. In 2018, the Scientific Committee reported that catches of yellowfin tuna exceeded by 3% the management measures previously agreed by the Commission that called for reductions in catches; reductions that did not even meet the scientific advice.

“Fisheries managers must act to protect Indian Ocean yellowfin,” said ISSF President Susan Jackson. “The scientific evidence regarding the status of Indian Ocean yellowfin is well-documented and concerning, and the IOTC has the power to adopt management measures that will rebuild this stock. The IOTC must heed the advice of its Scientific Committee and adopt effective management measures to reverse the decline of this critical resource.”

For yellowfin tuna, a species that is subject to overfishing, an over-catch of 3% places further stress on this resource. According to ISSF, IOTC should adopt an effective rebuilding plan for yellowfin tuna that: gives full effect to the advice of the IOTC Scientific Committee and achieves a healthy spawning biomass for the species by 2024 with at least 50% probability.

ISSF also advocates that IOTC:

Adopt species-specific harvest strategies as soon as possible, particularly for yellowfin tuna, and conduct a review of the limit reference points (LRPs) in Resolution 15/10 to allow for the adoption of harvest control rules by 2020.
Urgently address data gaps in artisanal fisheries, especially for gillnets.
Strengthen monitoring, control and surveillance (MCS) measures, such as vessel monitoring systems (VMS) and the regional observer scheme (ROS), to support data collection, monitoring and the implementation of harvest strategies.
Strengthen fish aggregating device (FAD) management, including of supply and tender vessels; ensure full implementation of non-entangling FADs; and support testing of biodegradable FADs.
Amend Res. 11/04 to require 100% observer coverage on large-scale purse seine vessels; adopt the ROS Standards for national programs; and develop electronic monitoring/electronic reporting(EM/ER) standards so that EM can be used to ultimately achieve 100% observer coverage in purse seine and longline fisheries.
Continue to strengthen the IOTC compliance assessment process.

Pacific fisheries ministers push for WCPFC reforms

June 11, 2019 — Fisheries ministers in the Pacific said while stocks of bigeye, yellowfin, albacore, and skipjack tuna are all to be in a healthy condition in the Western and Central Pacific Ocean, there should be no room for complacency on management measures as it could “lead to increased commercial pressure on those fisheries.”

The Parties to the Nauru Agreement is made up of the Federated States of Micronesia, Palau, the Marshall Islands, Kiribati, Tuvalu, Nauru, the Solomon Islands, Papua New Guinea, and Tokelau, which collectively maintain a purse-seine vessel day scheme (VDS). According to a communique signed by the ministers at the end of the annual PNA meeting in Palau on 30 May, all tuna stocks in the region are at healthy levels.

Scientists with the Pacific Community or SPC has earlier reported that Western and Central Pacific tuna stocks are healthy compared to other stocks in other oceanic regions due to the conservation measures implemented by PNA. The total annual tuna catch in PNA waters is around 1.6 million metric tons, including about 50 percent of the world’s supply of skipjack tuna. About half of the total tuna catch from PNA waters, or about 790,000 metric tons, is certified by the Marine Stewardship Council.

“Ministers welcomed the scientific advice that all major tuna stocks in PNA waters were reported as healthy and none were assessed as overfished or subject to overfishing,” the announcement stated.

However, the PNA statement said maintaining healthy tuna stocks is only possible with a continued effort to strengthen regional management of the fisheries.

86% of Global Tuna Catch Continues to Come from Stocks at Healthy Levels, But Some Stocks Remain Overfished

April 4, 2019 — The following was released by the International Seafood Sustainability Foundation:

Of the total tuna catch, 86% came from stocks at “healthy” levels — an unchanged share since last reported in October 2018 — according to the March 2019 International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. Skipjack tuna stocks — which remain at healthy levels in all ocean regions — still comprise over one-half of the total catch.

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

The fishing mortality rating was changed for two stocks since the previous report: The Fishing Mortality rating for both Mediterranean albacore and Western Pacific yellowfin was modified from “yellow” to “green.” The ISSF Scientific Advisory Committee (SAC) determined that this change was needed to harmonize those ratings and the report’s ratings methodology.

Though many of the recent broad indicators of overall global tuna stock health are positive, there are several stocks of concern that should be noted:

The Indian Ocean yellowfin stock has again been rated both as overfished and as suffering overfishing after a new stock assessment presented by the Indian Ocean Tuna Commission (IOTC) Scientific Committee in late 2018.
Similarly, the Pacific Ocean bluefin stock is also considered to be overfished, and overfishing of this stock continues.
Eastern Pacific bigeye is experiencing overfishing. Fishing mortality for this species is high.
Two consecutive assessments have concluded that Atlantic Ocean bigeye is overfished and that overfishing is still occurring.

Key Statistics in the Report

Total catch: In 2017, as reported in the new report, the total major commercial tuna catch was 4.8 million tonnes. More than half of the total catch (58%) was skipjack tuna, followed by yellowfin (28%), bigeye (8%) and albacore (5%). Bluefin tunas (3 species) accounted for only 1% of the global catch. These percentages changed only slightly from the October 2018 Status of the Stocks report.
Abundance or “spawning biomass” levels: Globally, 65% of the 23 stocks are at a healthy level of abundance, 13% are overfished and 22% are at an intermediate level. In terms of total catch, 86% come from healthy stocks, 10% from overfished stocks and 4% from stocks at an intermediate level. Unchanged from the last report, the stocks receiving orange scores — indicating overfished status — were Atlantic Ocean bigeye, Pacific Ocean bluefin and Indian Ocean yellowfin.
Fishing mortality levels: 78% of the 23 stocks are experiencing a well-managed fishing mortality rate, 18% are experiencing overfishing, and 4% have a high fishing mortality rate.
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 changed only slightly since the October report.

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. TheStatus 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 “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.

ISSF Sponsors Global Contest to Reward Marine Science Scholars’ Innovative Ideas for Sustainable Tuna Fishing

March 13, 2019 — The following was published by The International Seafood Sustainability Foundation:

Marine-science graduate students and postdoctoral researchers interested in helping to pioneer the next generation of sustainable tuna fishing initiatives — especially to reduce bycatch and protect ocean ecosystems — are invited to submit their ideas to the first-ever International Seafood Sustainability Foundation (ISSF) Seafood Sustainability Contest.

The contest opens today to eligible individuals and teams worldwide, who have until midnight December 31, 2019, to submit online entries. Competition judges will announce one $45,000 Grand Prize winner and one $10,000 Runner-Up Prize winner on February 28, 2020. The Grand Prize includes a trip (airfare and travel expenses paid for) for the winning individual or team representative to attend a major tuna sustainability conference or event selected by ISSF with the potential to present the winning idea to diverse stakeholders. Watch a video about the contest.

Tuna species provide a critical source of food and nutrition, economic benefits, and employment opportunities throughout the globe. Tuna comprise a massive 5 percent of the total worldwide fish trade and help contribute to a value chain estimated to be worth $42 billion, making it among the world’s most valuable fish. Commercial tuna fishing, regardless of the fishing method, must be practiced and managed as sustainably as possible to prevent overfishing and to protect other marine species and ocean ecosystems that can be impacted by commercial fishing practices.

Contest Launches 10th Anniversary Celebration

The ISSF Seafood Sustainability Contest inaugurates the commemoration of ISSF’s first “decade of discovery” (2009-2019), which has been marked by productive partnerships with marine scientists, seafood companies, vessels, Regional Fisheries Management Organizations (RFMOs), charitable foundations, retailers, and fellow NGOs. “Ten years ago, ISSF formed out of a shared vision and commitment that more could be done — and needed to be done — for the protection and long-term sustainable use of tuna stocks,” said ISSF President Susan Jackson. “A great deal has been accomplished over that time period, and we’re proud of the legacy we’ve built as ambassadors for science and as collaborators with the diverse collection of NGOs, foundations, retailers, and fishers working in this space. Our tenth-anniversary Seafood Sustainability Contest will allow us to tap into a talented pool of up-and-coming marine science students. We can’t wait to dive into their ideas, and are eager to support potential solutions that result from it.” To complement and enrich ISSF’s scientific program — which encompasses at-sea research, skippers workshops, and technical reports, for example — the Seafood Sustainability Contest seeks innovative proposals for achieving one or more of these goals in tropical tuna purse-seine fisheries that use Fish Aggregating Devices (FADs), which harvest most of the world’s tuna

Reducing the bycatch and fishing mortality of sharks
Reducing the bycatch and fishing mortality of marine mammals
Maximizing the catch of skipjack tuna in FAD sets while minimizing the catch of yellowfin and bigeye tuna(Skipjack stocks are at healthier levels of abundance than yellowfin and bigeye stocks)
Reducing the impacts that lost FADs can have on ocean ecosystems and habitats, such as beaching and pollution

A panel of five judges composed of experts drawn from academia and the fishing industry will determine the winners based on the originality of the idea, conservation impact, impact on skipjack catches, the degree to which idea has been tested, the feasibility of industry-wide implementation, and cost-effectiveness.

Before preparing and submitting entries to the Contest, participants must read the official rules. (No purchase necessary. Void where prohibited.)

A Decade of Discovery

In 2009, acclaimed scientists, leaders in the industry, and environmental champions launched the International Seafood Sustainability Foundation (ISSF) based on shared concerns about the future of global tuna fisheries and a desire to do something about it — together.

ISSF has worked for the long-term conservation and sustainable use of global tuna fisheries through its three pillars of Science, Influence, and Verification:

· Tuna Conservation: Through regular status of the Stocks Reports, ISSF creates a window into tuna-stock assessments on a global scale for management, science, and conservation interests.

· Bycatch Mitigation: Through-sea research, ISSF-supported scientists uncover new lessons, develop ideas and solutions, and implement strategies and tactics for bycatch mitigation. ISSF develops and disseminates their discoveries and best practices through globalSkippers Workshops.

· Seafood Company Compliance: ISSF evaluates participating company compliance with all ISSF Conservation Measures – including an emphasis on traceability from product to processing facility to fishery to vessel – and communicates those results publicly to promote transparency.

· Advocacy: Along with NGO partners and other allies, ISSF regularly advocates for critical new RFMO measures to improve global conditions around IUU fishing, deployment of monitoring, control and surveillance technology, harvest control rules, increased observer coverage, and improved data collection.

· ProActive Vessel Register: Through the ProActive Vessel Register(PVR), ISSF manages and updates a publicly accessible database of 1,000+ vessels, across all gear types, committed to transparency in their adherence to science-backed and auditable fishing practices. ISSF launched a new 5-year Strategic Plan in 2018, which formalized support for fisheries improvement activities. Visit the Strategic Plan microsite to learn more.

Bigeye tuna fishery gains MSC certification for first time

March 7, 2019 — A Chinese-operated longline yellowfin and bigeye tuna fishery, located in the Federated States of Micronesia, has become the first bigeye tuna fishery to achieve Marine Stewardship Council certification.

The fishery – owned by Liancheng Overseas Fishery (Shenzhen) Co. Ltd. (SZLC), China Southern Fishery ShenZhen Co. Ltd. (CSFC), and Liancheng Overseas Fishery (FSM) Co. Ltd. (FZLC) – gained the certification after an independent assessment. The fishery earlier earned certification for yellowfin tuna in October 2018.

“We are extremely proud to have the first bigeye tuna fishery to be certified to the MSC Standard,” Sam Chou, president of SZLC, said. “It is a distinct honor. Liancheng is the largest Chinese fleet to achieve MSC certification. We are dedicated to achieving certification for all our fisheries.”

The latest stock assessment for bigeye tuna in the area shows stocks are healthy, and being fished at a sustainable rate. According to the MSC, the certification is conditional upon the adoption of harvest strategies including harvest control rules that include all the member states of the Western Central Pacific Fisheries Commission by 2021.

“We congratulate Liancheng and their partners for becoming the first fishery to be eligible to sell MSC certified bigeye tuna. They are demonstrating true leadership in sustainable fishing,” Bill Holden, senior fisheries outreach manager for the MSC in Oceania and Southeast Asia, said. “To maintain their certification, Liancheng will need to work with other fishing organizations and the WCPFC to agree to important management measures to safeguard bigeye tuna stocks. As a result, this certification could influence the sustainability of bigeye fishing across the entire WCPO.”

Tuna investigation slams use of FADs in Indian Ocean

February 15, 2019 — An investigation by French state television broadcaster France 2 into the use of fish aggregating devices (FADs) to catch juvenile yellowfin tuna in the Indian Ocean, aimed to highlight the dark side of the industry to consumers.

Use of FADs has been widespread since the 1980s, but their use now sits at the center of global discussions on the long-term sustainability of tuna stocks and the ecological impact of tuna fisheries. An addition to being associated with the catch of juvenile tuna, FADs are linked to bycatch of vulnerable non-target species such as barracudas, sharks, and turtles, the modification of tuna habitat, damage to coastal habitats from lost and broken-up structures that end up on beaches, and interference with other maritime activities, France 2 reported.

FADs can be natural or artificial floating objects or rafts, which are often made from local materials such as wood, bamboo, pieces of net, twisted rope and floats. They can either be anchored in place or left untethered to drift on the ocean surface. GPS tags are used to facilitate location, and fishers use them as a highly-effective method of improving catch rates and reducing operating costs, as tuna are attracted to the debris.

According to the FAO, in spite of intensive research, the reason why fish are attracted to FADs remains a mystery, but it is possible that they are attracted to floating objects that provide a refuge from predators.

In the two-hour long documentary, entitled “Peche industrielle: gros poissons en eaux troubles,” (Industrial fishing: big fish in troubled waters), which was broadcast on Tuesday, 6 February, presenter Sophie le Gall told viewers that the long-term future of the fishery was under threat because many of the fish being caught are immature and have therefore not had the chance to reproduce.

DON CUDDY: Seafood comes in many forms — how fresh is yours?

November 27, 2018 — We live, as we are often reminded, in the top grossing fishing port in the United States and have some of the planet’s most productive fishing grounds right off our shores. So for those among us who enjoy and appreciate the harvest of the sea, and its clean, healthy, wild-caught protein, there is no better place to live than New Bedford. Lately however I have begun to wonder just how many people around the SouthCoast are fish eaters and include our excellent seafood as a regular part of their diet? Apart from perhaps ordering fish and chips or fried scallops in a restaurant on a Friday night that is. That counts certainly but what I have in mind is selecting some seafood at the market and bringing it home.

I regularly enjoy eating all kinds of great seafood at my house. In the past couple of weeks, I have bought, prepared and eaten swordfish, yellowfin tuna, haddock, scallops and oysters, all of it fresh and of surpassing excellence. On the other hand I have read that the vast majority of seafood consumed in the USA is confined to just three varieties — shrimp, salmon and canned tuna. I’m not a fan of shrimp nowadays as most of it is imported, farmed in Southeast Asia under dubious conditions, and I find the end product to be devoid of flavor. Decades ago when I lived in Miami, I would catch shrimp, one at a time, using a dip net and lantern as they entered Biscayne Bay via Government Cut so I know what wild shrimp tastes like.

Salmon fares a little better chez moi although wild salmon runs have all but disappeared on the East Coast and the commonly used marketing term ‘Atlantic salmon’ means that it is raised in pens, predominantly in the Canadian Maritimes and Norway. Both of these items enjoy great popularity in the restaurant trade and you will frequently find salmon and shrimp on seafood menus where even such New England staples such as cod and haddock are absent. But even at the local fish counter there is a high probability that the cod and haddock on offer, while fresh, is not caught or landed here.

ISSF expands reach across longline tuna sector

November 21, 2018 — The International Seafood Sustainability Foundation (ISSF) has announced the adoption of two new conservation measures “to facilitate continuous improvement across global tuna fisheries”.

ISSF also amended two of its existing conservation measures. Adoption of the new measures back the expansion of its efforts to the longline fishing sector, doubling the number of measures that apply to longline vessels specifically, the first of which were adopted in April 2017.

All ISSF conservation measures directly affect how nearly 30 global seafood companies environmentally manage their respective tuna supply chains, it said.

“Our work at ISSF is ever evolving. We regularly review ISSF conservation measures to update existing standards or to create new commitments in line with the latest fisheries research or to address conservation needs,” said ISSF President Susan Jackson. “With about 75% of the world’s canned tuna processing capacity conforming to dozens of ISSF measures for sustainability best practices — and with major tuna companies being transparently audited against these measures — we are driving unique and positive change across the world’s tuna fisheries.”

The ISSF ProActive Vessel Register (PVR) is a public internet database that tracks detailed vessel information and how vessels are following science-based practices that support sustainable tuna fisheries. MRAG Americas, a third party, independent auditor, audits vessels that join the PVR with respect to these practices; vessels that join the PVR commit to provide regular, accurate information about those activities. Because the PVR brings transparency to the tuna supply chain, ISSF has worked to increase the number of fishing vessels on the Register lists — from less than 200 vessels in 2012, the year it was launched, to more than 1,000 as of Oct. 31, 2018.

ISSF to ICCAT: Rebuild Bigeye and Yellowfin Tuna Stocks; Improve FAD Data Reporting; and Strengthen Monitoring, Control and Surveillance

November 6, 2018 — The following was released by the International Seafood Sustainability Foundation:

The International Seafood Sustainability Foundation (ISSF) has released its position statement in advance of the 21st Meeting of the International Commission for the Conservation of Atlantic Tunas (ICCAT) in Dubrovnik, Croatia, on 12-19 November 2018.

“The 2018 assessment of bigeye tuna shows that the stock is overfished and subject to overfishing, and yellowfin may also be subject to overfishing. ICCAT must take urgent action,” said ISSF President Susan Jackson.

“This time last year, ICCAT scientists were reporting that the established catch limits for bigeye and yellowfin had been exceeded in 2016 by 11% and 16%, respectively. Fast-forward to today and the bigeye catch limit has been exceeded by 20 percent, and yellowfin catch limit by 17 to 37 percent. The management of these valuable tuna stocks is getting worse, not better. More should have been done last year, and the upcoming meeting in Dubrovnik offers another chance to get it right.”

ISSF is asking ICCAT to adopt stock-specific management measures in line with the advice of the ICCAT scientific committee, which includes: appropriate and fully-allocated catch levels so that ICCAT member countries can know their individual limits; capacity limits that are commensurate with these allocations; and provisions to ensure catches are in compliance with the limits. ICCAT must also consider alternative means to reduce the mortality of bigeye and yellowfin tuna in the purse seine fishery—measures like strengthened FAD management, limitations on the use of supply and support vessels, and expanded time/area closures and effort controls.

Micronesia’s longline yellowfin tuna fishery achieves MSC certification

October 15, 2018 — The longline yellowfin tuna fishery in the exclusive economic zone of the Federated States of Micronesia has achieved Marine Stewardship Council (MSC) certification.

Three Chinese companies pursued the certification and own and operate the vessels in the fishery: Liancheng Overseas Fishery (Shenzhen) Co. Ltd (SZLC), China Southern Fishery Shenzhen Co. Ltd (CSFC) and Liancheng Overseas Fishery (FSM) Co. Ltd. (FZLC). The fishery produced 745 metric tons of yellowfin tuna in 2016.

“We are extremely proud to achieve this very significant achievement and to be a part of the MSC program,” Overseas Fishery (FSM) President Samuel Chou said in a press release. “We believe that, along with our other MSC certifications, Liancheng now has more MSC longline certifications than any other tuna fleet, and we remain dedicated to continuing our efforts to upgrade all our fisheries currently in fishery improvement projects to MSC status.”

The Federated States of Micronesia is composed of more than 600 islands in the Western Pacific Ocean, and fish and seafood products represent 95 percent of the country’s total exports. Eugene Pangelinan, director of Micronesia’s National Oceanic Resource Management Authority, which manages the country’s marine resources, said the certification represents a step forward in maintaining the country’s fishing effort as sustainable.

“Achieving MSC certification demonstrates our commitment to a sustainable fishery,” Pangelinan said. “We congratulate Liancheng for their achievement and we hope that this certification will generate more interest in joining our efforts to develop our longline fishery for the benefit of all stakeholders.”

Worldwide, more than one million metric tons of tuna caught per year is MSC certified, representing around 25 percent of the global tuna catch, according to MSC Oceania Program Director Anne Gabriel.
