| Description of life cycle and mating behavior | Produces 15,000-20,000 eggs at the age of 6-7 years (Ref. 12259). Spawns for several years. Semi-anadromous populations undertake long distance spawning migrations while lacustrine populations migrate to fast-flowing tributaries. In Dniepr and Kuban, migration starts in September, decreases in winter and resumes in March-May (Ref. 59043). |
