| Beschrijving van levenscyclus en paargedrag | Spawning adults move into tributaries and males establish territories. At spawning, the male follows a female, courting her with displays of his dorsal fin. He then drifts over beside her and curves his extended dorsal fin over the female. The pair vibrates and release eggs and milt. No redd is constructed, but the vibrations of the tails during the spawning act stirs up the substrate and produce a slight depression (Ref. 28876, 28879, 28880, 28881, 28882). A female may spawn only once, or several times in different areas (Ref. 1998). After spawning, adults establish summer territories in pools generally farther upstream from the spawning site, majority moving downstream in mid-September (Ref. 28885, 28886). |
