Comments: Known from MacIntyre River drainage, N.S.W. to Avon River drainage (Ref. 7300). Recorded from Victoria, Tasmania and South Australia (Ref. 44894). Feed selectively on small endemic fishes and fish fry and may have affected the numbers of galaxiids, pygmy perch, Nannoperca australis, and the golden perch, Macquaria ambigua in southern rivers (Ref. 12257). Common where there is abundant aquatic vegetation. 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. The dietary preferences have created fears among conservationists who believed this species adversely affects stocks of native fishes including Murray cod, Macquarie perch, pygmy perches and rainbow fishes. The egg mass is unpalatable to other fish and is therefore protected. The eggs hatch in 1-3 weeks and the young form schools for some time before taking up a solitary existence (Ref. 44894). Used to be cultured commercially in Australia (Ref. 7306). Also Ref. 1739.

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 14 - 20; Radios blandos dorsales (total) : 13 - 16; Espinas anales: 2; Radios blandos anales: 7 - 10; Vértebra: 39 - 42. 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).

Biología     Glosario (por ej. epibenthic)

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).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

During breeding, males arrive at the spawning area ahead of the females. One or two of these males chases a ripe female as soon as it arrives in the area (polyandry) (Ref. 6258). The queue of males maybe longer composed of about 15 to 25 individuals, but only two prod their snouts against the female's belly (Ref. 205). After rounds of curved course through the interlacing branches near the surface (Ref. 205), males fertilize the egg ribbon as the female lays them over weeds or other submerged objects (Ref. 6258). Eggs grouped in long white ribbons (up to 1 m) are found over submerged objects (Ref. 41678). Eggs hatch in about 8 to 16 days at normal temperatures (Ref. 6258). Males mature at 2-3 years and females at 4 years. Spawning, in the Northern hemisphere, happens in spring in waters with temperatures between 7-8°C. Eggs are laid in sticky strings becoming fixed to aquatic plants and rocks. Incubation lasts about 1- 8 days at 1- 3°. Egg size 2.0-2.5mm, larval length at hatching 5mm.
