| Descripción del ciclo vital y del comportamiento de acoplamiento | Sexually mature fish migrate upstream into smaller and shallower (0.3-1.5 m deep) streams (Ref. 26170), usually in upper reaches of tributaries (Ref. 59043). Males arrive first at spawning sites. Males defend females against other individuals. Spawning usually occurs during daytime (Ref. 59043). Spawns on gravelly bottom where female makes a shallow hole where the eggs are laid and covered with gravel (Ref. 682). Both sexes covered the eggs with substrate. They both defend the spawning site up to 2 weeks after spawning. Eggs usually hatch after 25-40 days. Larvae stay in gravel until yolk sac is absorbed after 8-14 days (Ref. 59043). Young remain near spawning area feeding on bottom fauna. Spawns with snow melt, in shallow water in Danube or affluents (Ref. 682). |
