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 species (CPS; i.e.: Pacifc Sardine Sardinops sagax, Northern Anchovy Engraulis mordax, Pacifc Mackerel Scomber japonicus, Jack Mackerel Trachurus symmetricus, Pacifc Herring Clupea pallasii, and Round Herring, Etrumeus acuminatus) in the California Current Ecosystem of the west coast of the United States (U.S.) and Mexico (MX); and 2) estimates of the biomasses, distributions, and demographics of those CPS encountered in the survey area between 6 July and 15 October 2021.
