ISSF: How Can Tropical Tuna Purse-Seine Fisheries Become MSC Certified?

April 19, 2018 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

The International Seafood Sustainability Foundation (ISSF) has published a comprehensive report of recommendations, with an emphasis on fish aggregating device (FAD) usage, for purse-seine fisheries pursuing Marine Stewardship Council (MSC) certification. ISSF 2018-05: Recommended Best Practices for Tropical Tuna Purse Seine Fisheries in Transition to MSC Certification, with Emphasis on FADs is based on MSC fishery-certification requirements and organized by MSC scoring indicators. It is intended as a practical resource for purse-seine fisheries entering into Fishery Improvement Projects (FIPs) to address problems, close gaps, and earn MSC certification.

The report summarizes science-based best practices for tropical tuna purse-seine fisheries with a FAD component — that is, with a portion of their sets on FAD-associated schools of tuna. Many of the practices also apply to purse-seine fishing on free-swimming tuna schools.

MSC Certification, Purse-Seine Fisheries, and FIPS

Approximately 65% of the world’s tuna is harvested from purse-seine fisheries, which have been challenged in receiving MSC certification as compared to other species fisheries. Only certain components of some purse-seine fisheries — the free-swimming school, anchored FAD, and dolphin-associated components — have been certified by MSC to date.

Helping all tuna fisheries to be sustainable and meet MSC certification standards — without conditions — is ISSF’s ultimate objective. Since FIPs are instrumental in that process, ISSF’s new five-year strategic plan, Advancing Sustainable Tuna Fisheries,emphasizes tools and resources, along with scientific expertise and RFMO advocacy, to support those improvement projects.

More than 30 tuna FIPs are active worldwide today, and many retailers and food-service providers are committed to FIPs in their seafood sourcing guidelines.

Best Practices in FAD Fishing

In Recommended Best Practices, ISSF marine scientists Ana Justel-Rubio and Dr. Victor Restrepo — who also sits on MSC’s Technical Advisory Board — reference requirements from Regional Fisheries Management Organizations (RFMOs) and present best practices gleaned from ISSF at-sea research, skippers workshops, and other resources.

Regarding FAD use, they identify several best practices for vessels operating in a tuna purse-seine fishery seeking certification, including:

  • Comply with flag state and RFMO reporting requirements for fisheries statistics by set type
  • Voluntarily report additional data on FADs for use by RFMO science bodies
  • Support science-based limits on the overall number of FADs used and/or FAD sets
  • Use non-entangling FADs only, and promote the use of biodegradable FADs
  • Develop a FAD recovery policy, including arrangements to alert coastal countries of derelict FADs that may impact sensitive areas
  • For silky sharks (the main bycatch species in FAD sets), implement further mitigation efforts
Recommendations to Increase MSC Scores
In addition to best practices for FAD use, the report recommends strategies for fisheries to:
  •  Promote RFMO adoption of stock management measures that address all fishing gears
  •  Increase research and monitoring capabilities
  •  Improve overall compliance with RFMO requirements, including reporting of data needed for stock assessment

An appendix lists all MSC performance indicators (PIs) for each MSC Principle — Sustainable Fish Stocks (P1), Minimizing Environmental Impact (P2), and Effective Management (P3) — and their component scoring issues (SIs), identifying actions that will lead to passing scores of 80 or higher.

 

ISSF Report Analyzes Purse Seine Tuna Fishing Impacts on Sharks, Rays, and Other Species

November 28, 2017 — The following was released by the International Seafood Sustainability Foundation:

Using data from Regional Fisheries Management Organizations (RFMOs), scientific observer programs, and its own at-sea research and skippers workshops, the International Seafood Sustainability Foundation (ISSF) has published an updated report that documents purse-seine tuna fishing’s impact on “non-target” species. The bycatch species covered in the report are sharks, whale sharks, rays, finfish, sea turtles, and billfish. While they are not bycatch species, the report also touches upon catches of undesirably small bigeye and yellowfin tunas.

Organized by species and including graphics and a full bibliography, “ISSF 2017-06: A Summary of Bycatch Issues and ISSF Mitigation Activities to Date in Purse Seine Fisheries, with Emphasis on FADs”:

  • Identifies issues of concern for each species
  • Summarizes the effectiveness of different bycatch-mitigation practices — at different stages of fishing operations — for either avoiding non-target species or reducing their mortality when caught
  • Describes ongoing ISSF bycatch research activities
  • Lists existing RFMO measures for minimizing bycatch

“A Summary of Bycatch Issues” is intended to be a useful reference for fishers and tuna companies, scientists, regional fisheries management organizations (RFMOs), government agencies, nongovernment organizations (NGOs) including conservation groups, and others interested in helping fisheries to be more sustainable.

Report Data and Insights Can Guide Conservation Efforts
The November 2017 report, authored by ISSF staff and collaborating scientists Victor Restrepo, Laurent Dagorn, David Itano, Ana Justel-Rubio, Fabien Forget, and Gala Moreno, is an update of a 2014 publication.

Not all non-target species are equally vulnerable to becoming bycatch in purse-seine fisheries, and bycatch rates for a single species can vary across oceans. For some species, other fishing methods have higher bycatch than purse-seine fishing. Here are some key findings in the report:

  • SHARKS: 90% of sharks that become entangled in FAD nets in purse-seine fisheries are silky sharks (Carcharhinus falciformis); the oceanic whitetip shark ( longimanus) is another bycatch species. By avoiding setting on small schools of tuna (e.g. < 10 tons) around FADs, fishers could significantly reduce their catches of silky sharks by 20% to 40%, depending on the ocean.
  • WHALE SHARKS: Whale shark (Rhyncodon typus) interaction rates with purse seiners are very low: The Western and Central Pacific Fisheries Commission (WCPFC), for example, recorded a set encounter rate of 0.94%. But any whale shark fishing mortality is a concern due to their life history and ecological significance. Time/area fishing closures do not appear effective for avoiding catching whale sharks, but best practice guidelines for their release exist.
  • RAYS: Rays are not common bycatch in purse seine fisheries, at less than 0.1% by weight, and are mostly caught in free-school sets. Release from the deck is a viable alternative to release from the net. Fishers should avoid using hooks, wires or tightening slings and lifting or dragging by the gill slits or cephalic lobes.
  • SEA TURTLES: Sea turtles are caught in very small numbers by purse seiners, with most (> 90%) released alive relatively easily. Using non-entangling FADs can prevent turtle entanglement.
  • UNDESIRABLY SMALL BIGEYE AND YELLOWFIN TUNAS: Bigeye and yellowfin are not considered non-target species. Nonetheless, FAD fishing for skipjack stocks can result in higher catches of small bigeye and yellowfin, which can contribute to their overfishing. The species’ slower growth rates, higher longevity and higher age at maturity increase vulnerability to fishing. Mitigation efforts being evaluated include: adjusting the relative prices of small bigeye and skipjack tuna; setting species-specific quota; temporarily closing to fishing some areas of high concentrations; or managing the number of fishing sets on floating objects.

ISSF on Bycatch Mitigation
Since its inception in 2009, ISSF has dedicated resources and efforts to understanding bycatch issues in tuna fisheries (see “Related ISSF Activities” sections in the report). In addition to publishing scientific reports, ISSF hosts bycatch-mitigation workshops and publishes guidebooks and videos for skippers and other stakeholders. The Foundation also advocates science-based, mitigation measures to RFMOs through meetings and side events, position statements, and joint letters.

Commercial vessels catch about 4.7 million tons of tuna annually. Purse-seine vessels dominate large-scale tuna fishing, harvesting about 64% of the tropical tuna catch (skipjack, yellowfin, and bigeye tuna). Many purse seiners use Fish Aggregating Devices (FADs) or other floating objects to attract tuna to their nets, although they also may pursue sets on free-swimming tuna schools. More than half of the total tropical tuna landings globally are made by sets on FADs or other floating objects.

Bycatch occurs across most major tuna fishing methods — including longline, gillnet, and troll — and all fishing methods can affect the marine environment in multiple ways beyond bycatch.

Spanish Tuna Fishers Embrace Best Practices to Mitigate Bycatch, Report Reveals

The International Seafood Sustainability Foundation (ISSF) has conducted 10 Skippers Workshops in Spain since 2009, and will hold the 11th October 16-20 in Sukarrieta

664 Spanish fleet professionals have been reached by ISSF Skippers Workshops, representing 25% of the2,736 tuna fleet professionals trained worldwide

October 16, 2017 — MADRID — The following was released by the International Seafood Sustainability Foundation and the Organization of Associated Producers of Large Tuna Freezers (OPAGAC):

The Spanish tuna fishing fleet remains one of the most receptive and active worldwide in adopting International Seafood Sustainability Foundation (ISSF) best practices for mitigating bycatch — a commitment reflected in the fleet’s high attendance at ISSF Skippers Workshops each year and as revealed in ISSF Technical Report 2017-03: ISSF Skippers’ Workshops Round 6.

ISSF’s recommended best practices include using non-entangling Fish Aggregating Devices (FADs) and following handling-and-release techniques for non-target species (e.g., turtles and sharks) to maximize their survival. The Spanish fleet has consequently increased the number of its vessels with specific tools for bycatch mitigation, such as stretchers or loading nets.

Since 2011, the Spanish fleet also has been instrumental, together with the French, in contributing to ISSF’s non-entangling FADs research and development — an example followed by additional fleets more recently in the development and testing of biodegradable FADs.

From training to practice

The Spanish fleet’s acceptance and application of key ISSF best practices is directly related to ISSF vessel outreach, specifically via its Skippers Workshops. According to ISSF Technical Report 2017-03 — co-authored by ISSF staff and consulting scientists, including those from AZTI, which has facilitated these workshops since 2009 — nearly 25% of all persons who have participated in ISSF workshops since they began are affiliated with the Spanish fleet.

At an August 2016 workshop in Spain, at the headquarters of the Port of Vigo Shipowners Cooperative (ARVI), more than 90 professionals participated. That year, ISSF conducted 14 workshops in seven countries, including Spain, with the participation of 343 skippers from 12 purse-seine fleets and another 216 people, including crew members and other professionals from the fishing sector.

Of the 2,736 tuna fleet professionals in the world trained at ISSF workshops to date, 664 — 63% are skippers and 19% are crew members — have participated in one of the 10 workshops that ISSF has given in Spain. The rest of the professionals affiliated with Spanish vessels participated in workshops held in countries where the fleet has a presence, such as Ecuador and Panama.

The next Skippers Workshops will be held on October 16-20 in Sukarrieta (Vizcaya), the site of the one of the earliest ISSF workshops. More than 50 participants are expected, and one of the event’s key topics will be biodegradable FADs — on which ISSF works in collaboration with the tuna fishing industry and other strategic partners.

According to Julio Morón, Managing Director of OPAGAC, “ISSF engagement is essential so that our crew members and, specifically, skippers of vessels are familiar with and can carry out activities ranging from the use of non-entangling FADs to the release of bycatch, which are part of the foundation of fishing that respects the marine environment and resources.

Further, all Spanish tuna purse-seine vessels are on the ISSF’s ProActive Vessel Register (PVR), which audits vessels to show how they are meeting specific measures for sustainable fishing.”

According to Víctor Restrepo, ISSF Vice President, Science and Chair, ISSF Scientific Advisory Committee, “Close collaboration between scientists and skippers has made it possible to conduct significant research projects, such as those on the Albatún 3 and Mar de Sergio purse-seine vessels in the Western Pacific and the Atlantic, respectively, and which will be key to the BIOFAD project in testing new biodegradable FADs in the Indian Ocean.”

The Majority of the Tuna Catch Comes from Abundant Stocks, But Overfishing of Some Stocks Continues

September 22, 2016 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

The global commercial catch of tuna — a valuable, natural protein food source — reached 5 million tons in 2014, an increase from 4.6 million in 2013, according to the ISSF Tuna Stock Status Update – 2016 (Status of the World Fisheries for Tuna) report just published by the International Seafood Sustainability Foundation (ISSF). The report can be downloaded from the ISSF Status of the Stocks page. Tuna accounts for approximately 6% of the world’s 81.5-million-ton marine catch.

The skipjack tuna species accounted for 57% of the tuna catch, followed by yellowfin (27%), bigeye (9%), albacore (6%) and bluefin (1%). Purse seine vessels harvested 64% of the tuna, followed by longline methods (12%), pole-and-line (9%), gillnets (4%) and miscellaneous fishing gear types (11%).

The ISSF report indicates that 77% of the total volume of tuna catch worldwide in 2014 was from stocks at a “healthy level of abundance.” Previous Tuna Stock Status Update reports showed 78% of tuna catch from healthy stocks in 2014 (from a preliminary report in February 2016), 87% in 2013, 86% in 2012, and 94% in 2011.

From a perspective of tuna stocks, 44% of tuna stocks globally are at a healthy level of abundance, and 39% are overfished. Eastern Pacific Ocean (EPO) bigeye tuna, for example, continues to be slightly overfished and was downgraded from a Green (healthy abundance) rating to a Yellow (intermediate) rating since the previous February 2016 report. Other overfished stocks were Western Pacific Ocean (WPO) bigeye, Atlantic Ocean (AO) bigeye, and Indian Ocean (IO) yellowfin.

Tuna Stock Status Update also reports on tuna management measures recently enacted by tuna Regional Fisheries Management Organizations (RFMOs). Significant newly adopted measures covered in the report include the adoption by the IOTC (Indian Ocean Tuna Commission) of harvest control rules (HCRs) for skipjack tuna, as well as a plan for rebuilding the overfished IO yellowfin stock. The IATTC (Inter-American-Tropical-Tuna-Commission, in the EPO) also adopted an HCR for tropical tuna species.

“While 77% of the world’s tuna catch comes from healthy stocks, it is important to remember that there are four stocks — representing 13% of the catch — that are being overfished,” explains Dr. Victor Restrepo, ISSF Vice President, Science. “Even though there are management measures in place for them, these measures are proving to be insufficient to end overfishing — and a greater effort is required.”

International Seafood Sustainability Foundation to Hold its First China Skipper Workshop

April 5, 2016 — WASHINGTON — On April 6, the International Seafood Sustainability Foundation (ISSF) will expand its global series of skipper workshops to China for the first time since the Foundation began the unique platform for knowledge exchange in 2009. The Shanghai workshop is the result of a collaboration between ISSF and the China Overseas Fisheries Association (COFA) and will engage tuna purse seine fishers, crew members and fleet managers in an event that seeks to share best practices for sustainable tuna fishing and mitigate fishing’s impact on the marine ecosystem.

“ISSF skipper workshops have reached more than 900 skippers to date, covering nine fleets in 2015 alone,” said Dr. Victor Restrepo, Vice President of Science at ISSF and chair of its Scientific Advisory Committee. “With roughly 790 large scale purse seine vessels operating today, we know we are engaging a substantial portion of the purse seine capacity on a global basis. Expanding these workshops to the Chinese fleet is an imperative next step as we work toward the global development and adoption of best practices for bycatch reduction and more in the world’s tuna fisheries.”

“We are pleased to welcome ISSF to Shanghai to help us continue to make improvements to ensure that bycatch is mitigated, that there is better compliance by Chinese tuna fishing fleet on bycatch measures adopted by t-RFMOs, and that tuna stocks remain healthy,” said Zhao Gang of COFA.

Dr. Jefferson Murua, with the Marine Research Division of Azti-Tecnalia, will lead the workshop in Shanghai. For seven years, ISSF has commissioned scientist presenters to traverse the world in an effort to share best practices with tuna fishers in every port. The outreach focuses on purse seine fisheries, where the use of fish aggregating devices (FADs) is often employed, and emphasizes the importance of maximizing the survival of species. Particular attention is paid to species like sharks and rays, and reducing waste from small tuna and other fish species. The workshops are also an important opportunity for scientists to dialogue with fishers about what techniques and tools may be most successfully implemented given the variable dynamics of the world’s tuna fisheries. These interactions, in turn, help inform ISSF’s bycatch research priorities as ISSF continues to identify and advance sustainable fishing practices. Previous skipper workshops have been held in Panama, Ecuador, Mexico, Spain, Ghana, the Seychelles, Mauritius, Micronesia, the Marshall Islands, USA, Korea, Indonesia, Philippines, American Samoa and more. Additional workshops in 2016 will target the fleets of Indonesia, China, Spain, Ecuador, Ghana, USA and Venezuela.

In addition, all ISSF participating companies – tuna processors and marketers that represent around 75% of the world’s tuna processing capacity – are required to purchase tuna from vessels whose skippers have reviewed these best practices, either by attending a workshop in person or taking advantage of ISSF’s additional skipper outreach materials, specifically ISSF skipper workshop videos or skippers guidebooks, both of which are available in multiple languages. Participating companies are audited against this commitment annually, the results of which are shared in the aggregate in an annual compliance report as part of ISSF’s annual report.

This multi-faceted effort – from on-the-ground workshops to company commitment and compliance auditing and reporting – are part of ISSF’s holistic work to help tuna fisheries make continuous improvements as they edge closer to becoming more robustly sustainable and capable of meeting the Marine Stewardship Council (MSC) certification standard without conditions.
