21st Regular Session of the Scientific Committee

Agenda Item 6.5.1 Review of CMM for sharks (CMM 2024-05)

Paragraphs 29–30 of the CMM task the Scientific Committee (SC) with periodically assessing the stock status of key shark species and evaluating the impact of fishing gear on non-retained sharks, including oceanic whitetip and silky sharks, while providing advice on mitigation measures—preferably in collaboration with the Inter-American Tropical Tuna Commission.

In addition, SC21 will consider any information submitted in response to CMM provisions concerning the review of safe release and bycatch mitigation measures (paras 20–23), biological sampling and species-specific requirements (paras 24–25), data provision and research support (paras 26–28), and preparatory work for the Commission’s 2027 review of the measure (para 33).

SC21 will deliver advice or recommendations to the Commission based on its review of these elements.
