Proposal to SRFC member states - Protocol to amend the CCMA - Strenthening the fight against IUU fishing through the use of the (AIS) [Version 5] Mbengue, Y.S. /Brehmer, Patrice Diakhaté, A.K. Ly, I. The Automatic Identification System (AIS), adopted by the Sub-Regional Fisheries Commission (SRFC) member states (MS), plays a role in maritime security. However, its effectiveness in combating illegal fishing remains limited because its use is not legally mandatory for foreign fishing vessels under 300 gross tonnage (GT) operating in the waters under the jurisdiction of SRFC MS. It is proposed that AIS use be made mandatory for foreign fishing vessels entering the waters under the jurisdiction of SRFC MS. This measure, coupled with the establishment of a binding sub-regional legal framework, would substantially reduce illicit activities by foreign fishing vessels. This would provide a new tool for surveillance bodies, promote a participatory approach, and strengthen maritime surveillance and security. It would also facilitate the boarding of infringing vessels, increase the effectiveness of control actions (even in the absence of observed illegal fishing offences) and enable better cooperation among member states. Finally, AIS data serves as a source of information for calculating fishing effort and as a tool for participatory surveillance.
