Diagnosed from other species of Percidae in Europe by having the following unique characters: pelvic and anal fins yellow to red; posterior part of first dorsal fin with dark blotch; and flank with 5-8 bold dark bars, usually Y-shaped. Differs further by the combination of the following features: two dorsal fins, clearly separated from each other; and 56-77 scales along lateral line (Ref. 59043). Body greenish-yellow; 5-9 transverse black bands on the sides; first dorsal fin gray, black spot at the tip; second dorsal greenish-yellow; pectorals yellow; other fins red. First dorsal fin markedly higher than the second. Caudal fin emarginate (Ref. 2058).

Habitat and Ecology
A very wide range of habitats from estuarine lagoons, lakes of all types to medium sized streams.
Biology:
Lives up to 21 years, usually to about six years. Males reproduce for the first time at 1-2 years, females at 2-4 years. Spawns in February-July, depending on latitude and altitude, when temperature reaches about 6C. May undertake short spawning migrations. A female usually spawns with several males, once each year. The female circles the spawning site, followed by one male, while other males remain stationary. The egg strand is released as the female swims in spiral clockwise movements, folding herself into a U-shape. All eggs are released and fertilised within about 5 seconds in a single strand, which becomes twisted around and entangled with spawning substrate. Feeding larvae are positively phototactic, live in open water and feed on pelagic organisms. They may be widely distributed by currents. An opportunistic diurnal feeder, preying mainly at sunrise and sunset, using all available prey. Larvae and small juveniles usually prey on planktonic invertebrates. During first summer, many juveniles come near shores to feed on benthic prey. Often becomes piscivorous at about 120 mm SL. Stocks with different life-histories may co-occur in some lakes (littoral, benthic feeding, pelagic zooplanktivorous), sometimes with different spawning sites and times.
