Habitat Type: Freshwater
Comments: Adults migrate from the ocean or lake to spawning streams. Landlocked populations in lakes may migrate up to about 50 miles upstream for spawning. Anadromous populations with access to the ocean migrate up to a couple hundred miles. Females deposit numerous small eggs in nests made by males in gravel, sand, and rubble of streams with moderately strong current. Larvae burrow in sand and silt bottom in quiet water downstream from spawning areas and filter-feed on plankton and detritus.
