Annotation
SC22 will receive an update on the informal intersessional review of CMM 2018-04, including a draft revised CMM, and provide feedback for the Commission’s consideration and possible adoption at WCPFC23.

WCPFC22 endorsed the establishment of an informal intersessional working group (led by the USA) to review CMM 2018-04 in 2026 and report to SC22, TCC22, and WCPFC23. The First Sea Turtle Informal Intersessional Working Group Meeting (STIIWG01) was convened virtually on 8 and 10 April 2026 to consider recent scientific information and potential options to improve the current CMM on sea turtles.
