Report: At Least 1,843 Purse Seine Vessels Fishing for Tuna Worldwide Today, A Slight Decrease versus 2018 Analysis

The International Seafood Sustainability Foundation (ISSF) has issued an updated “snapshot” of Large-Scale Tuna Purse Seine Fishing Fleets report as of June 2019. The total number of purse seine vessels, calculated based on data from the five tuna Regional Fisheries Management Organizations (RFMOs), has decreased from 1,871 in 2018 to 1,843 today, mainly due to the removal from RFMO lists of vessels under 24m that are now inactive.

Having an accurate estimate of active vessels is critical for managing tuna fishing capacity regionally as well as globally. Although purse seine vessels account for approximately 65 percent of the 4.9-million-tonne global tuna catch, multiple databases must be searched to count all authorized purse seine vessels. To provide an annual best estimate — and to track capacity changes from year to year — ISSF analyzes and aggregates information from the five tuna RFMOs and other sources. As the report explains, these figures may underestimate the total fleet, because many small-scale purse seiners or purse seiners operating in only one exclusive economic zone (EEZ) do not have to be listed on RFMOs’ records of authorized fishing vessels.

Through its research, ISSF found that in the tropical tuna large-scale purse seine (LSPS) fleet, fish hold volume (FHV) grew by 1 percent since 2018. The report shows approximately 686 vessels (up 2 percent, from 673 last year) defined as large-scale purse seine (LSPS) vessels targeting tropical tuna species (skipjack, yellowfin, and bigeye), with a combined fishing capacity of over 860,000 m3. The increase is not all due to new vessel constructions, but also to the addition to RFMO lists of older vessels that were not listed in the past. These vessels may have been inactive for some time or participating in a different fishery, but this type of information is not readily available.

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

  • About 18 percent of the 686 large-scale vessels are authorized to fish in more than one RFMO.
  • About 2 percent of these vessels changed flags in the last year.
  • Among the RFMOs, the Western and Central Pacific Fisheries Commission (WCPFC) still has the highest number of LSPS registrations (347), more than half of the total worldwide.
  • The majority of large-scale vessels (515) are registered on the ISSF ProActive Vessel Register (PVR); PVR-registered LSPS represent 75 percent in number and 83 percent in fish hold volume (FHV).

In addition, the report shows that 97 percent of the large-scale tropical tuna purse seiners operating today have publicly known International Maritime Organization (IMO) numbers; in 2011, that figure was 12 percent. Nearly 100 percent of the purse seine vessels listed on PVR have IMO numbers. ISSF has long recommended in its RFMO advocacy positions and in Conservation Measures 4.1 and 4.2 that vessels obtain IMO numbers, identifiers that do not change even if the vessel ownership, national registration, or name changes. Unique vessel identifiers (UVIs) like IMO numbers are an important tool to combat illegal, unreported and unregulated (IUU) fishing. 

The report also covers purse-seine vessel construction, distribution, and FHV by national flag. It offers recommendations for vessel owners on registration and for RFMOs on vessel-data collection and management. View the updated report here.

International Workshop on Mitigating Environmental Impacts of Tropical Tuna Purse Seine Fisheries

ISSF and the Common Oceans ABNJ Tuna Project co-sponsored the workshop held at the Food and Agriculture Organization of the United Nations’ (FAO) Headquarters in March 2019. The workshop reviewed the progress cross-sector research and advocacy efforts have made in reducing bycatch and other environmental impacts and identified main focus areas for future activities. This video offers a brief overview of the workshop and interviews with attendees.

Improved Monitoring, Reduced Fishing Pressure and Strengthened FAD Management Needed for Sustainable Eastern Pacific Ocean Tuna Fisheries

The International Seafood Sustainability Foundation (ISSF) released its position statement in for the 94th Meeting of the Inter-American Tropical Tuna Commission (IATTC) in Bilbao, Spain, from July 22-26, 2019.

“The Commission took some important steps last year, including the adoption of a technical definition for non-entangling FAD designs, a binding measure on safety at sea for human observers and to require International Maritime Organization (IMO) numbers on all fishing vessels greater than 12m,” said ISSF President Susan Jackson. “However there were many important issues left unresolved and these must be urgently addressed this year.”

Our position statement for #IATTC outlines priority topics for the Commission's meeting this week. Click To Tweet

As top priorities, ISSF urges IATTC to:

  1. Develop a set of options to limit fishing pressure by the purse seine fleet, such as limiting fish aggregating device (FAD) deployments, further limiting the number of active FADs per vessel, and/or limiting the number of all set types.
  2. Strengthen FAD management through science-based measures, including a transition to FADs that do not use nets, and to encouraging the provision of echo-sounder data for scientific purposes.
  3. Fund knowledge-sharing, capacity-building and communication of scientific advice, including the establishment of a scientist-manager dialogue process and the development of harvest strategies for all key tuna species.
  4. Require 100% observer coverage (human or electronic) for longline vessels, small class purse seine vessels and all vessels engaged in at-sea transshipment within five years, and develop minimum electronic monitoring and reporting standards.
  5. Adopt measures to mitigate the incidental catch and maximize post-release survival of sharks, mobulid rays and sea turtles, and require all sharks be landed with fins naturally attached.
  6. Strengthen the IATTC compliance assessment process.

ISSF Global Priorities for Tuna RFMOs

ISSF is committed to advocating for science-based approaches, policies and conservation measures to advance tuna fisheries sustainability. The following are ISSF’s Global Priorities for Tuna Regional fisheries management organizations (RFMOs), specifically, the Indian Ocean Tuna Commission (IOTC), the Inter-American Tropical Tuna Commission (IATTC), the International Commission for the Conservation of Atlantic Tunas (ICCAT) and the Western and Central Pacific Fisheries Commission (WCPFC):

  • Implementation of rigorous harvest strategies, including harvest control rules and reference points
  • Effective management of fleet capacity, including developing mechanisms that support developing coastal state engagement in the fishery
  • Science-based FAD management & non-entangling FAD designs
  • Increased member compliance with all adopted measures adopted, and greater transparency of processes reviewing member compliance with measures
  • Strengthened MCS measures and increased observer coverage, including through modern technologies such as electronic monitoring and e-reporting; and
  • Adoption of best-practice bycatch mitigation and shark conservation and management measures

Sharing Best-Practice: IPNLF & ISSF Launch First Practical Reference Guide for Pole-and-Line Fishing

A new guidebook detailing science-based best-practices for maximising catch value and also minimising the environmental impacts of these fisheries is today jointly published by and the International Pole & Line Foundation (IPNLF) and the International Seafood Sustainability Foundation (ISSF).

The Skippers’ Guidebook to Pole-and-Line Fishing Best Practices has been written by fishers, marine scientists and pole-and-line experts. Aimed at one-by-one fishers and fishery stakeholders, the Guidebook offers practical advice on conducting these artisanal tuna fishing operations — from capture to handling and storage methods.

ISSF and @IPNLF have teamed up to produce their first #sustainability guidebook for #pole and #line #fishers. Click To Tweet

As highlighted in the Guidebook, pole-and-line fishing has gained attention as a responsible method of harvesting tuna. With the growing consumer awareness about the sustainability of seafood resources, this Guidebook is well placed to provide a resource for fishers globally to optimise the efficiency of their operations, maximise catch quality and recognise and address the environmental impacts of their activities in order to reach the increasing demand for pole-and-line caught products.

Topics covered by the guidebook include:

  • Tuna species targeted by pole-and-line fisheries
  • Fishing operations in pole-and-line tuna fishing
  • Tuna catch handling and storage
  • Baitfish catch methods, management, and utilisation in pole-and-line fisheries

The chapters include a comprehensive series of examples and recommendations to help pole-and-line fishers understand and implement best-practise guidance.

Dr. Victor Restrepo, Vice President of Science at ISSF, says: “ISSF is committed to the long-term conservation and sustainable use of global tuna fisheries. That commitment drives the publication of the ISSF Skippers Guidebook series for longline and purse seine vessel fishers, as well as our observer guidebook — sharing best practices with those stakeholders on the front lines of the collaborative work toward sustainable fisheries. Having expert advisors on our respective science committees in common, ISSF is pleased to partner with the International Pole and Line Foundation in expanding such science-based guidance to the pole-and-line sector.”

Martin Purves, Managing Director of IPNLF, adds: “We believe the Skippers’ Guidebook will prove an important, practical resource not only for the many thousands of pole-and-line fishers around the world, but also for all those many more people connected to these supply chains. The profile of pole-and-line fishing has reached new levels, not only due to the low environmental impacts of these fisheries, but increasingly also because of the social benefits that they bring to the coastal communities connected to them. Like any catch method there is significant scope for further improvements in the sustainability aspects of these fisheries, providing markets with higher quality, more responsibly sourced tuna. There’s no question that this is what today’s consumers are looking for.”

The Skippers’ Guidebook to Pole-and-Line Fishing Best Practices is available online on the ISSF and IPNLF websites.
