Description:

This report provides: 1) a detailed description of the acoustic-trawl method (ATM) used by NOAA’s Southwest Fisheries Science Center for direct assessments of the dominant coastal pelagic species (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 of the west coast of the United States (U.S.) and portions of Baja CA, Mexico (MX); and 2) estimates of the biomasses, distributions, and demographics of those CPS encountered in the survey area between 27 June and 30 September 2022.
