The bill aims to combat illegal, unreported, and unregulated (IUU) fishing by establishing an IUU vessel list and imposing visa sanctions on foreign individuals involved in IUU fishing activities. It encourages international cooperation, improved management and enforcement at regional fisheries organizations, data sharing, and investment in sustainable fish stock management. Additionally, it mandates the development of a strategy to identify seafood harvested using forced labor, and requires reports on new technology's impact on illegal fishing, collaboration between Russian and Chinese fishing industries, and unlawful fishing in the exclusive economic zone. The bill also authorizes appropriations for specified programs and clarifies existing authorities.
