Ecoregions

    Special needs

    May aggregate in high densities. Requires fine gravel beds for spawning. Larvae burrow in fine sediment. Timing of development closely linked to water temperature.

    Limiting factors

    Reduced water quality. Passage barriers. Altered flow patterns. Dredging. Rapid water draw-downs.

    Conservation actions

    Improve passage. Alter timing of water draw-down. Use species-specific habitat requirements to guide management actions. See results of Lamprey Workgroup 2005 for strategies.
