Description of life cycle and mating behavior Undergo upriver migration (100 km in Dniepr) to spawn. Many populations start spawning migration in autumn ( especially semi-anadromours forms), slow down during winter and continue in spring. Males often defend spawning territories along shorelines. Eggs are sticky and eggs size increases with age of female. Frequently forms fertile hybrids with Rutilus rutilus (Ref. 59043).
