Adds counter-illegal, unreported, and unregulated (IUU) fishing operations to the Department of Defense’s foreign security force capacity-building authority and directs the Secretary of the Navy and the Commandant of the Coast Guard to pursue joint patrols with foreign partners to combat IUU fishing, transnational crime, and improve regional maritime security. Requires a joint report to specified congressional committees within one year of enactment and then annually, describing engagements, assessments, and recommendations.

Does not appropriate funds or create new penalties; it modifies existing authority, mandates operational coordination between the Navy and Coast Guard, and establishes recurring reporting to Congress.
