| Description du cycle de vie et comportement d'accouplement | Spawns once a year for several years in low productivity streams, but exhibits multiple spawning within a season in high productivity environments (Ref. 40290, 40756). Releases eggs above substrate which drift with current, sink to the bottom and stick to substrate. Larvae and juveniles occur on the bottom and prefer detritus-rich sandy habitats and low current (Ref. 59043). |
