Life cycle and mating behavior النضج | التكاثر | وضع البيض | بيض | الخصوبة | Larvae

The males care about the eggs for about 14 days (Ref. 93240) as well as the young (Ref. 2060). In Europe where it is introduced, males fan and defend the nests, which are shallow depressions in sand or gravel bottom along shallow shores. A male may spawn with several females in one nest and guard the nest until larvae leave the nest (Ref. 59043).
