生態學
; 淡水 底中水層性. 溫帶; 5°C - 20°C (Ref. 2060)
Oceania: endemic to south-eastern Australia, including Tasmania (Ref. 5259). Mictochodrial 12S rRNA sequences support that G. marmoratus complex consists of two northern and southern forms (Ref. 54370).

Lives in clear, flowing streams with abundant cover (Ref. 5259, 44894). Prefers streams with gravel bottoms and abundant snags. Also occurs in lakes and reservoirs (Ref. 5259). Tolerant of slightly brackish conditions (10 p.p.t.) in the tidal reaches of rivers, and a temperature range of 5°-25°C. Home-ranging; remaining within about a 20-30 meters stretch of water throughout the life span (Ref. 44894). Feeds on insects, crustaceans and small fishes (Ref. 5259) ; also on mollusks (Ref. 2156). The spawning season runs from November to January. A popular angling species in the south, but large fish are rare. Highly susceptible to overfishing, due to its home-ranging behavior and low fecundity (Ref. 44894). Flesh is oily and not very good eating.
生活在清澈又流動的溪流有豐富的表面.(參考文獻 5259) 偏愛溪流有礫石的底部與豐富的斷枝。 也生活於湖與水庫中。 (參考文獻 5259) 吃昆蟲，甲殼動物與小魚 ;(參考文獻 5259) 也在軟體動物上.(參考文獻 2156) 肉是多油的而不是非常好的吃。
