| Mô tả chu kỳ sống và tập tính ghép đôi | Courtship begins with a male attempting to drive a female toward suitable spawning gravel. A receptive female chooses a spot and digs a redd. While the female is digging, the male continues courtship activity, darting alongside the female and quivering, swimming over and under her and rubbing her with his fins; most of the time however, is spent driving off other males. When the redd is completed, the pair enter the nest and deposit eggs and milt. After spawning the female covers the eggs by sweeping small pebbles at the downstream edge of the redd upstream. Once the eggs are completely covered, she moves to the upstream end of the redd and begins digging a new redd (Ref. 27547). |
