Description of life cycle and mating behavior | 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). |
