European perch (Perca fluviatilis) fish species information

Scientific Name
Perca fluviatilis

Common Name
European perch

Biology
Inhabits a very wide range of habitats from estuarine lagoons, lakes of all types to medium-sized streams. Feeding larvae occur in open water. This is an opportunistic diurnal feeder which preys mainly during sunrise and sunset, using all available prey. Larvae and small juveniles usually feed on planktonic invertebrates. During first summer, many juveniles move near shores to feed on benthic prey. Often feeds on fishes at about 12 cm SL. May undertake short spawning migrations. Males attain first sexual maturity at 1-2 years and females at 2-4 years of age. Spawns in February-July (Ref. 59043). Eggs grouped in long white ribbons (up to 1 m) are found over submerged objects (Ref. 41678). Its flesh is excellent and not so bony. Utilized fresh and frozen; eaten pan-fried and baked (Ref. 9988). May be captured with natural or artificial bait (Ref. 30578).
