Northeast Atlantic: throughout the Mediterranean and along the European coasts to Arctic Circle; also found in most of the Baltic Sea. Subspecies Psetta maxima maeotica in the Black Sea.
Adults live on sandy, rocky or mixed bottoms; rather common in brackish waters. Feed mainly on other bottom-living fishes (sand-eels, gobies, etc.), and also, to a lesser extent, on larger crustaceans and bivalves. Batch spawner (Ref. 51846). Spawning season is between April and August; pelagic eggs. May reach 25 kg (Ref. 9988). Highly esteemed food fish. Utilized fresh or frozen; eaten steamed, pan-fried, broiled, boiled, microwaved and baked (Ref. 9988).
