Upstream spawning migration in summer to areas behind the peak of the flood. Spawning commences late in the afternoon from the surface to a depth of about 4 m, where there is a flow over a gravel, rock rubble substrate. Considerable spawning activity happens at the water surface. A single female circles slowly to the surface with her head deep and several males participate in courtship and finally in fertilization (Ref. 2906).大洋洲: 已知只來自 Murray-Darling 河流域，澳洲了。 排列邊界: Chinchilla(在 Condamine 河上) ，昆士蘭省南方部， Bonshaw(在 Dumaresq 河上) ，東北方的新南威爾斯， Albury(在默里河上) ，東南方的新南威爾斯, 七條小溪與 Goulburn 河, 南方的維多利亞。
