Abstract Under the 1994 amendments to the Marine Mammal Protection Act (MMPA), the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (USFWS) are required to publish Stock Assessment Reports for all stocks of marine mammals within U.S. waters, to review new information every year for strategic stocks and every three years for non-strategic stocks, and to update the stock assessment reports when significant new information becomes available. The 2011 Pacific marine mammal stock assessments include revised stock assessments for nine Pacific marine mammal stocks under NMFS jurisdiction, including four strategic stocks (Hawaiian monk seal, Southern Resident killer whale, Hawaii Insular false killer whale, Hawaii Pelagic false killer whale), and five non-strategic stocks (California sea lion, California harbor seal, Northern Oregon/Washington coast harbor porpoise, Washington Inland waters harbor porpoise, and Palmyra Atoll false killer whale). New information on a population viability analysis for the stock of Hawaii Insular false killer whale is presented. NMFS has received a petition to list this stock as endangered under the ESA. A Take Reduction Team was established in 2010 with the goal of reducing mortality and serious injury in the Hawaii Pelagic, Hawaii Insular, and Palmyra stocks of false killer whale (75 FR 2853, 19 January 2010). Information on the remaining 66 Pacific region stocks can be found in the final 2010 reports (Carretta et al. 2011). New abundance estimates are available for five stocks (California sea lion, California harbor seal, Hawaiian monk seal, Southern Resident killer whale, and Hawaii Insular false killer whale). Updated information on human-caused mortality is presented for the two harbor porpoise stocks and the three stocks of false killer whale.
