Description:"A minimum biomass estimate of the central subpopulation of northern anchovy (Engraulis mordax) in summer 2016 using the acoustic-trawl method (ATM) was determined to be 151,558 metric tons (t), CV = 41.0%. The anchovy, ranging from the Mexican border to north of San Francisco, CA, but primarily observed north of Point Conception, had standard lengths ranging from 6 to 15 cm with a prominent mode at 11 cm. This mode is consistent with growth of the 6-cm mode observed in 2015, and indicates that the 2015 year-class currently dominates the stock in the survey area"--Summary.
