生物学特性     字汇 (例如 epibenthic)

Adults are found in rivers, lakes and reservoirs, preferring fast-flowing waters of rapids and races and usually forming aggregations near the surface. Usually found below rapids and weirs (Ref. 44894). Feed on aquatic insects, mollusks, earthworms and plants. Temp.: 2-37°C. Maturity: F, 3 y and 34 cm SL; M, 23.3 cm SL. Spawning: summer (Nov.-Jan., 23-30°C water temp.), effect upstream migration. Fecundity: 500000 eggs per 1.8kg. Eggs: pelagic, 2.7-2.8 mm diameter. Hatching: 30 hrs at 26-27°C. Larvae: 3.6 mm at hatching. A good angling and food fish which has been increasingly utilized as an aquaculture species in farm dams throughout Australia (Ref. 44894).

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼

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).
