How to reproduce
The fish prepares for reproduction from mid-spring, when the temperature warms up to 18°C. Spawning lasts until July. To spawn, catfish swim to shallow areas with weak currents and lay their eggs in algae. During the mating season, males chase females.
Each female is accompanied by 4 males. She will choose from the group the same size as herself. The pair builds a nest in which the eggs are laid, which the male guards until the fry emerge. During the spawning period, the female produces 100-450 thousand eggs. On the tenth day, the fry emerge and feed on the yolk sac. After a month, they disperse around the pond in small groups.
