Description:The coastal pelagic species (CPS) fisheries along the U.S. West Coast in the Northeast Pacific Ocean are managed under the CPS Fisheries Management Plan and include four finfish species: Pacific jack mackerel (Trachurus symmetricus), northern anchovy (Engraulis mordax), Pacific sardine (Sardinops sagax caerulea), and Pacific mackerel (Scomber japonicus). The instantaneous rate of natural mortality (M) is an important parameter for assessment and management of these and other species. A synthesis of literature on M for each of these species has the potential to contextualize and improve estimation of M in future stock assessments. To this end, a brief synthesis of various methods for deriving estimates, inferences, or assumed values of M for managed CPS finfish along the U.S. West Coast was conducted.
