This bill would authorize the Secretary of Defense to train and build the military capacity of foreign countries to combat illegal, unreported, and unregulated fishing operations in their waters. The legislation amends existing Defense Department authority that already allows the military to assist foreign security forces in various capacities by adding fishing enforcement as a new area where the Pentagon can provide support. This affects foreign military and security forces whose governments want help protecting their fishing resources from illegal exploitation. The bill does not specify any particular funding amounts or timelines for implementation. The measure was introduced by representatives from Louisiana and California and referred to the House Armed Services Committee.
