Description:
This report provides: 1) a detailed description of the acoustic-trawl method (ATM) used by NOAA’s Southwest Fisheries Science Center (SWFSC) for direct assessments of the dominant species of coastal pelagic fishes (CPS; i.e., Pacifc Sardine Sardinops sagax, Northern Anchovy Engraulis mordax, Pacifc Mackerel Scomber japonicus, Jack Mackerel Trachurus symmetricus, and Pacifc Herring Clupea pallasii) in the California Current Ecosystem (CCE) of the west coast of North America; and 2) estimates of the biomasses, distributions, and demographies of those CPS in the survey area between 19 June and 11 August 2017. The survey area spanned most of the continental shelf between the northern tip of Vancouver Island, British Columbia (BC) and Morro Bay, CA.
