This legislation requires the Under Secretary of Commerce for Standards and Technology and the Administrator of the National Oceanic and Atmospheric Administration, in consultation with Customs and Border Protection and the Coast Guard, to develop a standard methodology for identifying the country of origin of seafood. This methodology must be based on chemical analysis and is intended to support enforcement efforts against illegal, unreported, and unregulated (IUU) fishing . Key requirements include consistency with law enforcement needs, minimized processing time, the use of a portable field kit, and the ability to test prepared seafood. The bill specifies that pilot studies for this methodology should focus on red snapper, representing a stationary stock, and tuna, representing a highly migratory stock. Furthermore, it authorizes the Secretary of Defense, in coordination with the U.S. Coast Guard, to expend funds for providing maritime technical assistance to foreign nations. This assistance aims to combat IUU fishing and other transnational organized crime, potentially including observers, shipriders, remote sensing, and operational intelligence to enhance international enforcement capabilities.
