[2] The multistakeholder group states its mission is "to undertake science-based initiatives for the long-term conservation and sustainable use of tuna stocks, reducing bycatch and promoting ecosystem health".

In 2010, Negocios Industriales Real NIRSA S.A., FRINSA, Conservas Garavilla, S.A. and Jealsa Rianxeira S. A. joined the ISSF founders as Participating Companies.

[12] In 2010, ISSF released its Strategic Plan with three distinct lines of approach for conservation and sustainability of tuna stocks – applied science, advocacy and direct market action.

The PVR identifies which of more than 25 ISSF Commitments each vessel has adopted, including implementing strategies to increase supply chain transparency, providing complete catch data to management bodies and continuing education in best practices that reduce fishing's impact on the greater marine environment.

According to ICCAT's Standing Committee on Research and Statistics (SCRS), bigeye tuna is on its way to recovering from an overfished state, but an increase in catches from the current level could reverse the trend.

Each cruise accomplished a series of tasks to test improved gear designs and study the behavior of tuna and non-targeted species gathering at FADs.

[18] ISSF Bycatch Project cruises paved the way for ISSF-lead workshops held in fishing ports in the Americas, Africa, Europe and the Pacific Islands region.

ISSF is calling on fishers, processors, governments and conservationists to put their strengths to work for the most commonly fished tuna species – skipjack, yellowfin, bigeye, and albacore.

The ISSF Board adopted a conservation measure to limit the growth in fishing capacity of the global large-scale tropical tuna purse seine fleet.

[25] The ISSF Board adopted a conservation measure calling on processors, traders and importers to refrain from transactions with purse seine vessels that do not have an onboard observer as of January 2013.
