Description

The European pilchard is a small to medium-sized, somewhat elongated, herring-like fish. The origin of the pelvic fins is well behind that of the dorsal fin, and the last two soft rays on the anal fin are larger than the remainder. The upper parts are green or olive, the flanks are golden and the belly is silvery.

Distribution and habitat

The European pilchard occurs in the northeastern

Ecology

In the Mediterranean, the European pilchard moves offshore in the autumn, preferring the deeper cooler waters and constant salinity out at sea to the variable temperatures and salinities of inshore waters. Spawning starts to take place in winter, and in early spring, juveniles, larvae and some adults move towards the coast, while other adults migrate inshore later in the year. Multiple batches of eggs are produced over a long breeding period, total

and phytoplankton. The zooplankton is largely copepods and their larvae, which make daily vertical migrations to feed near the surface at night, and this is when the adult pilchards feed on them; juveniles feed during the day as well. Along with the European anchovy (''Engraulis encrasicolus''), the European pilchard plays an important intermediate role in the Mediterranean ecosystem as a consumer of

where the water is shallow, the food chain is shorter and energy is retained within the basin; overfishing of pilchard and anchovy can thus cause dramatic changes in the ecosystem.
