Value of species
The genus Lota is in a need of critical revision. Populations from eastern Siberia and North America represent a distinct species, L. maculosa.
Widely distributed in western and eastern both hemispheres south to about 40 degrees north latitude (south to Pennsylvania, Kentucky, Missouri, Wyoming, and Oregon).
This species is represented by a large number of subpopulations and locations.
Total adult population size is unknown but relatively large.
Trend over the past 10 years or three generations is uncertain but likely relatively stable or slowly declining.
Common in deep (to at least 90 m) cold waters of lakes, reservoirs, and large rivers. In summer, stays in deep cold waters but may move into shallower water at night. Life history may be confined to lakes or rivers or may migrate between lake and riverine habitats; all three patterns may occur within a single river basin. Often exhibits a post-spawning movement into tributary rivers in late winter and early spring. Spawns usually in lakes but may move into rivers to spawn. River-spawning populations prefer low-velocity areas in main channels or in side channels behind deposition bars (see USFWS 2003). Broadcasts eggs usually over sand or gravel (sometimes silt) in up to about 10 ft of water (Scott and Crossman 1973).
