Seafood Companies Collaborating Through ISSF to Advance Sustainable Tuna Fisheries
Collaboration across the seafood supply chain plays an important role in advancing sustainable tuna fisheries worldwide.
Today, 97% of the global commercial tuna catch comes from stocks at healthy abundance levels, according to ISSF’s Status of the Stocks report—reflecting decades of science-based fisheries management and coordinated action across governments, scientists, fishers, and seafood companies.
Through participation in the International Seafood Sustainability Association (ISSA), seafood companies work alongside scientists, environmental organizations, and other industry stakeholders to support science-based conservation measures, strengthen transparency, and advance responsible fishing practices. ISSA supports the work of the International Seafood Sustainability Foundation (ISSF), whose initiatives focus on improving tuna fisheries through research, innovation, and the implementation of science-based best practices.
Participation in ISSA provides tuna companies with opportunities to:
- Support the development and implementation of science-based conservation measures
- Demonstrate sustainability commitments through independent audits against ISSF conservation measures
- Access transparency tools that support responsible sourcing, including the ISSF ProActive Vessel Register (PVR) and Vessels in Other Sustainability Initiatives (VOSI)
- Collaborate with scientists, NGOs, and industry partners to advance improvements in global tuna fisheries
Retailer and buyer policies increasingly reference ISSF participation and the use of these transparency tools as part of their sustainability expectations.

ISSF Adopts Conservation Measure on Social Audits for Land-Based Tuna Production Facilities
ISSF has adopted a conservation measure (CM) related to social and labor practices at land-based tuna production facilities owned or controlled by ISSF Participating Companies. ISSF Conservation Measure 9.2 – Social Audits for Land-Based Tuna Production Facilities establishes expectations for independent, third-party labor audits conducted under internationally recognized audit programs. The measure builds on ISSF’s existing CM 9.1 – Public Policy on Social and Labor Standards, strengthening implementation and verification at land-based operations.

Workshop Explores Use of Acoustic Technology to Improve Fishing Selectivity
In 2025, ISSF convened purse-seine and pole-and-line fishers with fisheries scientists in Bermeo, Spain, to discuss how acoustic discrimination technology may help improve fishing selectivity and reduce bycatch.
The workshop was supported by ISSF, FAO, and AZTI and is part of ISSF’s ongoing collaboration with fishers and researchers to advance practical improvements in tuna fisheries.
