Member nations of the Inter-American Tropical Tuna Commission have agreed to be bound by capacity limits to avoid overcapitalization of tuna fishing fleets in the Eastern Pacific Ocean. The capacity of U.S. purse seine vessels has approached the U.S. capacity limit in recent years, such that no additional vessels could be added to the Active and Inactive Purse Seine Vessel Register (Register), and requests to be added to the Register have exceeded the available Inter-American Tropical Tuna Commission-allotted limit. NMFS seeks to address this issue. This action is intended to inform the public of our planning efforts and request comment to identify ways to improve the utilization and management of U.S. capacity limits.
