Description:"The 2015 Pacific marine mammal stock assessments include revised reports for eight Pacific marine mammal stocks under NMFS jurisdiction, including five “strategic” stocks: Hawaiian monk seal, Southern Resident killer whale, Eastern North Pacific blue whale, Main Hawaiian Islands Insular false killer whale, and Hawaii Pelagic false killer whale. New abundance estimates are available for three stocks in the Pacific Islands region (Hawaiian monk seal, Hawaii Pelagic and Northwestern Hawaiian Islands false killer whales) and two U.S. west coast stocks (Southern Resident killer whale and California northern fur seal). The stock range and boundaries of the three Hawaiian stocks of false killer whales, which have overlapping ranges, were recently reevaluated based on new information on the occurrence and movements of each stock (Bradford et al. 2015). New information on fisheryrelated serious injury and mortality of false killer whales has also been updated. A stock assessment report for the Eastern Tropical Pacific stock of Bryde's whale has been reinstated into the Pacific reports in response to a regular and increasing presence of this species in southern California waters (Kerosky et al. 2012, Smultea et al. 2012). The Eastern Tropical Pacific Bryde's whale report last appeared in the Pacific stock assessments in 2007. The genus of Hawaiian monk seal has been updated from Monachus to Neomonachus to reflect recent genetic and skull morphology data (Scheel et al. 2014). The report for Eastern North Pacific blue whales includes significant new information on historic whaling removals, the population's status relative to carrying capacity, and risk of ship strikes to the population (Monnahan et al. 2014, 2015). This is a working document and individual stock assessment reports will be updated as new information on marine mammal stocks and fisheries becomes available. Background information and guidelines for preparing stock assessment reports are reviewed in Wade and Angliss (1997). The authors solicit any new information or comments which would improve future stock assessment reports"--Preface. [doi:10.7289/V5/TM-SWFSC-561(http://doi.org/10.7289/V5/TM-SWFSC-561)]
