U.S. Pacific Marine Mammal Stock Assessments: 2006 Technical memo

摘要

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. This report presents revised stock assessments for 9 Pacific marine mammal stocks under NMFS jurisdiction: 1) San Miguel Island northern fur seal, 2) Hawaiian monk seal, 3) Oregon/Washington coast harbor porpoise, 4) Washington Inland Waters harbor porpoise, 5) California coastal bottlenose dolphin, 6) Southern Resident killer whale, 7) Hawaii bottlenose dolphin, 8) Hawaii false killer whale, and 9) Hawaii short-finned pilot whale. Information on the remaining xx Pacific region stocks is reprinted without revision in this report and also appears in the 2005 reports (Carretta et al. 2006). Stock Assessments for Alaskan marine mammals are published by the National Marine Mammal Laboratory (NMML) in a separate report.
