Our “Change Over Time” line graph tracks changes since 2015 in the conformance percentages of ISSF participating companies in aggregate with ISSF conservation measures. It also shows changes in the number of companies and measures from year to year.
This graphic tracks compliance based on data published in the ISSF Annual Conservation Measures & ProActive Vessel Register Compliance Report (July 2025) (PDF).
Note that companies may remediate non-conformances after aggregate compliance reports like this are prepared and published. If there are remediations, we will publish “Update of Compliance Status” reports on our participating company audit reports page.
