Description
The Californian anchovy or northern anchovy (Engraulis mordax) is a species of anchovy found in the Eastern Pacific Ocean, ranging from Mexico to British Columbia. It is a small, Clupeoid fish with a large mouth and a long, laterally compressed body, which strongly resembles the European Anchovy (Engraulis encrasicolus) with only slight differences in girth and fin position. They have a euryhaline lifestyle defined by regular migrations between bays and open ocean for both spawning and foraging. Like Pacific sardines (Sardinops sagax), they compose a large fraction of the marine biomass in waters off the west coast of North America, where they are a vital keystone species in coastal pelagic waters. However, they are subject to seasonal boom & bust cycles that are chiefly caused by changes in water temperature and food availability; regularly switching places as the forage fish of prominence with the sardine during years defined by colder water temperatures, which makes them vulnerable to climate change. They have a small commercial fishery; mainly used as bait for fishermen or fish meal, with a dedicated small following as a food fish in San Francisco.
