| Comments: | Upstream migration begins in April or May (Ref. 28554). Some fish travel long distances to reach spawning sites and move upstream much earlier (perhaps even in the previous year) and spawn later (after June) than fish moving shorter distances (Ref. 27547). Spawning occurs in swift water over rocky bottoms (Ref. 1998). | |||||||||||
