| Spawning Cycles: | (1/y) | Ref: | |||||||||||
| Comments: | Spawning season commences at the end of April. Deposits eggs on the stony or sandy bottom. The incubation phase, which proceeds on the stones and gravel to which the eggs adhere, is particularly sensitive to the strong currents which occurs upon the release of hydroelectric barrages (Ref. 30578). | ||||||||||||
