    Geographical Distribution

    Launch the Aquatic Species Distribution map viewer

    Is one of the few species of freshwater fishes that occurs in both North America and Eurasia. It has been introduced to other parts of the world, for example Australia, New Zealand, and North America.
    Habitat and Biology
    Occurs in clear vegetated lakes, quiet pools and backwaters of creeks and small to large rivers. Usually solitary. Highly territorial predator. Enter brackish water in the Baltic.After the yolk is absorbed, young feed on large zooplankton and immature aquatic insects for about 7-10 days; fish then becomes the major part of the diet. Adults occasionally feed on frogs, crayfish and other vertebrates.Eggs and young are preyed upon by fishes, larvae of aquatic insects, birds, and aquatic mammals.Adults are preyed upon bears, dogs, eagles, and osprey during the spawning run.
    Maximum 130 cm; up to 34 kg; The largest fish are females, males rarely growing heavier than 6.3 Kg.
    Interest to Fisheries
    It is a valuable game fish. Excellent food fish; utilized fresh and frozen; eaten pan-fried, broiled and baked.This fish can be heavily infested with parasites, including the broad tapeworm which, if not killed by thorough cooking, can infect human; is used as an intermediate host by a cestode parasite which results to large losses in usable catches of lake whitefish Coregonus clupeaformis in some areas; also suffers from a trematode which causes unsightly cyst on the skin. The total catch reported for this species to FAO for 1999 was 24 920 t. The countries with the largest catches were Finland (11 663 t) and Russian Federation (6 118 t).
