This report presents revised stock assessments for 27 Pacific marine mammal stocks under NMFS jurisdiction, including nine “strategic” stocks and 18 “non-strategic” stocks (see summary table). New abundance estimates are available for 20 stocks, including five endangered species of large whales, the Hawaiian monk seal, and southern resident killer whales. Information on the remaining 37 Pacific region stocks will be reprinted without revision in the final 2008 reports and currently appears in the 2007 reports (Carretta et al. 2007).
