Golden perch live throughout the river systems, from the clear, fast flowing upper reaches to the turbid, slow flowing lower reaches and associated billabongs and backwaters. They favor deep pools with plenty of cover from fallen timber, rocky ledges or undercut banks (Ref. 27439, 44894). Prefer warm, slow-moving, turbid sections of streams. Also occur in flooded lakes, backwaters and impoundments. Tolerant of temperatures between 4° and 35°C and high salinity levels (up to 35 p.p.t.). Solitary species (Ref. 44894). Their diet is dominated by yabbies (Cherax destructor), and a variety of fish species (Ref. 27439). Juveniles disperse throughout the floodplain to find food and cover (Ref. 27440). They feed on abundant zooplankton on recently inundated floodplains (Ref. 6390, 44894). Adults feed on fishes, mollusks and crayfish (Ref. 44894). Spawn from early spring to late autumn. Golden perch is Australia's most migratory freshwater fish species (Ref. 6390). Spawn in flooded backwaters near the surface at night after heavy spring and summer rains. Usually a long upstream spawning migration is undertaken (movements of 2000 kilometers by tagged fish have been documented). Eggs float near the surface and hatch in 24-36 hours. Males mature after 2-3 years (20-30 centimeters), females after 4 years (40 centimeters) (Ref. 44894). They are being reared by private and government hatcheries in Victoria, New South Wales and Queensland (Ref. 27552) and the fry and fingerlings produced from these hatcheries are stocked in public waters and farm dams (Ref. 26869).
金鲈鱼在河流域各处生活, 从清澈的, 快速的流动上游到混浊的, 慢的流动下游与相连的死水潭与洄水区。 他们喜欢深水池有丰富的来自落下来的木材, 岩石的岩架或堤岸下的表面.(参考文献 27439,44894) 偏爱溪流的温暖的, 缓慢移动的, 混浊部分。 也生活于被水淹没的湖，洄水区与圈围水域中。 宽容的在 4个 ° 与 35 °C 与高的盐度之间的温度 (向上到 35 p.p.t.)。 一种独居性种.(参考文献 44894) 他们的食性被小形螫虾 ( Cherax 破坏者 ),與多種魚種控制。 (參考文獻 27439) 稚魚在洪泛區各處分散尋找食物而且覆蓋。 (參考文獻 27440) 他們在最近浸水的洪泛區上吃豐富的浮游動物。 (參考文獻 6390,44894) 成魚吃魚，軟體動物與小龍蝦。 (參考文獻 44894) 從初春到秋季末產卵。 金鱸魚是澳洲的最迴游的淡水魚種。 (參考文獻 6390) 產卵在重的春天與夏天雨後的被水淹沒的洄水區晚上接近水表面處。 通常一長的向上游產卵遷移被開始.(有標籤魚的 2000 公里的運動曾經証明) 卵飄浮接近水表面而且孵化在 2436 小時的。 雄性在 2-3 年 (20-30個公分) 之後成熟, 在 4 年 (40個公分) 之後的雌性.(參考文獻 44894) 他們被在維多利亞, 新南威爾斯被私人的與政府孵卵所後面，而且從這些孵卵所生產的昆士蘭省 (參考文獻 27552) 與魚苗與魚苗在公眾的水域與農場水壩被進貨。 (參考文獻 26869)

Under favourable conditions female golden perch are capable of spawning more than once a season (Ref. 27439). However, without suitable environmental cues they may fail to breed in season, with the eggs being resorbed (Ref. 27439). Spawning period is from early spring to late autumn (Ref. 6390). They commonly spawn at night (Ref. 6390).大洋洲: 澳洲，墨累－達令流域 (除了較高的支流), 昆士蘭東南部的道生-Fitzroy 系統。 也在愛麗湖與西方維多利亞的 Bulloo 河流域與洪泛區湖與新南威爾斯。 廣泛地引進了昆士蘭省與新南威爾斯的其他海岸系統。
