    Geographical Distribution

    Launch the Aquatic Species Distribution map viewer

    A family (Percidae) of freshwater fishes originally confined to the temperated waters of the northern hemisphere (Europe and North America), but representatives have been introduced to Australia, New Zealand, and South Africa.
    Habitat and Biology
    Occurs in slow-flowing rivers, deep lakes and ponds; avoid cold, fast-flowing waters but may penetrate into but not breed in such waters. Normally found lying close or amongst obstacles in the water. Common in some of the brackish waters of the Baltic Sea.A predatory species, juveniles feed on zooplankton, bottom invertebrate fauna and other perch fry while adults feed on both invertebrates and fish, mainly stickle-backs, perch, roach and minnows.
    Spawns between February and July in the northern hemisphere and between August and October in the southern hemisphere. 
    Size
    Attains a maximum length of 51 cm and weight of 4.75 kg; more usually 35 cm and 1.20 kg.
    Interest to Fisheries
    Its flesh is very good eating. Also important for game fishing. In Europe it is fished for and marketed as a food-fish; also used to be cultured commercially in Australia. The total catch reported for this species to FAO for 1999 was 2 421 t. The countries with the largest catches were Canada (1 884 t) and USA (537 t).
    Utilized fresh and frozen; eaten pan-fried and baked.
