Taxonomic Comments
C. tsiltcoosensis removed from synonymy with C. macrocheilus by Kettratad and Markle (2010).

Hybridizes with C. commersonii in a limited area in British Columbia (Scott and Crossman 1973). See Smith (1992) for a study of the phylogeny and biogeography of the Catostomidae.

Ecology & Habitat

Habitat

Habitat includes lakes, and pools and runs of medium to large rivers (Page and Burr 2011). Usually this sucker is in shallow water, but sometimes it occurs as deep as 80 feet. In lakes, it is often near stream mouths, along weedy shores, or in backwaters. Fry move to shallows to feed by day and to deeper water at night. Spawning may occur in sandy areas of streams; also along lake shorelines in areas with sand or gravel substrate.

Ecology

Life span may be up to 11 years. Predators of young suckers include fishes and fish eating birds. In shallow waters adults may be preyed upon by large mammals and birds (e.g., bears and eagles).

Reproduction

Usually mature by 4th or 5th year of life. Usually spawns in the spring when water temperatures reach 46-48 F. A female may deposit as many as 20,000 eggs; eggs hatch in about 2 weeks (Scott and Crossman 1973).
