NOAA Fisheries West Coast Region's Highly Migratory Species (HMS) Program works to develop, implement, and evaluate fisheries policies and regulations for managing sustainable fisheries for eastern Pacific Ocean species such as Pacific tunas, swordfish, sharks, and billfish. Because highly migratory species are found throughout the Pacific Ocean and migrate across jurisdictional boundaries, this program engages stakeholders and governmental groups in the management of these species at both domestic and international levels.
