Supporting the ISSF Board of Directors is a group of formal and informal partners – marine scientists, environmental stakeholders, fleet owners, and others – who are experts in their respective fields and provide their time and insights on a voluntary basis to inform the Board and the organization’s efforts.

ISSF is constructed on the belief that diversity of opinion, perspective and approach among those with shared interests and goals is not a hindrance – rather it is a great strength. The organization has established its role in the global sustainability community as a convener of common interests, a facilitator of dialogue, and a promoter of science-based approaches that can be practically applied across tuna fisheries to continuously improve global tuna stocks and their ecosystem.

This approach is reflected in the committees that help to inform our efforts. In addition to the Scientific Advisory and Environmental Stakeholder committees, ISSF staff is charged with working with stakeholders from the vessel and retail communities to ensure these critical on-the-front-lines partners are sharing recommendations on a consistent basis.

Environmental Stakeholder Committee

The ISSF Environmental Stakeholder Committee (ESC) comprises expert representatives from various conservation and scientific bodies who volunteer to provide their personal expertise. Members of the committee review information and provide analysis. Any involvement with the Foundation does not imply endorsement of policy decisions.
