Ecology & Life History
Help
Reproduction Comments: 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).
Ecology Comments: 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).
Habitat Type: Freshwater
Non-Migrant: N
Locally Migrant: N
Long Distance Migrant: N
Riverine Habitat(s): BIG RIVER, CREEK, MEDIUM RIVER, Pool
Lacustrine Habitat(s): Shallow water
Special Habitat Factors: Benthic
Habitat Comments: 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.
Adult Food Habits: Herbivore, Invertivore
Immature Food Habits: Herbivore, Invertivore
Food Comments: A bottom feeder. Eats aquatic insect larvae, crustaceans, snails, algae, detritus, etc. Young suckers feed primarily on plankton.
Length: 61 centimeters

Group Name: Medium suckers

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including eggs and larvae) in appropriate habitat.
Mapping Guidance: Occupied locations that are separated by a gap of 15 km or more of any aquatic habitat that is not known to be occupied represent different occurrences. However, it is important to evaluate migrations and seasonal changes in habitat to ensure that spawning areas and nonspawning areas for a single population are not artificially segregated as different occurrences simply because there have been no collections/observations in an intervening area that may exceed the separation distance.
Separation Barriers: Dam lacking a suitable fishway; high waterfall; upland habitat.
Separation Distance for Unsuitable Habitat: 15 km
Separation Distance for Suitable Habitat: 15 km
Separation Justification: Data on dispersal and other movements generally are not available. In some species, individuals may migrate variable distances between spawning areas and nonspawning habitats.

Separation distances (in aquatic kilometers) for catostomids are arbitrary but reflect the presumption that movements and appropriate separation distances generally should increase with fish size. Hence small, medium, and large catostomids, respectively, have increasingly large separation distances. Separation distance reflects the likely low probability that two occupied locations separated by less than several kilometers of aquatic habitat would represent truly independent populations over the long term.

Because of the difficulty in defining suitable versus unsuitable habitat, especially with respect to dispersal, and to simplify the delineation of occurrences, a single separation distance is used regardless of habitat quality.

Occupied locations that are separated by a gap of 15 km or more of any aquatic habitat that is not known to be occupied represent different occurrences. However, it is important to evaluate seasonal changes in habitat to ensure that an occupied habitat occurrence for a particular population does not artificially separate spawning areas and nonspawning areas as different occurrences simply because there have been no collections/observations in an intervening area that may exceed the separation distance.
