Character Abstract
Identification Comments:
Subspecies Comments:
Food Habits:This species is a surface feeder. Adults primarily eat terrestrial insects, plant debris, and algae, but can be an active predator on early life stages of other native and nonnative fishes. Young feed mainly on aquatic insects.
Phenology Comments:
Reproduction Comments:Spawned in Lake Mohave (1954) over gravel bar in 9 m (29.5 ft) of water. Spawns in schools over rocky shoals of smaller tributaries (Matthews and Moseley 1990).
Migration Mobility:
Habitat Comments:Bonytail chub are found in the main stream of the Colorado River and large tributaries, usually in or near deep swift water, in flowing pools and backwaters, over mud or rocks. They are most frequently associated with eddies just outside the main current, and have a high tolerance for turbidity (Matthews and Moseley 1990). They also occupy mainstem Colorado River reservoirs. Available data suggest that habitats required for conservation include river channels and flooded, ponded, or inundated riverine habitats, especially those where competition from non-native fishes is absent or reduced (USFWS 1994b).
Ecology comments:Bonytail chub spawned in Lake Mohave (1954) over a gravel bar in 9 m (29.5 ft) of water. They spawn in schools over rocky shoals of smaller tributaries (Matthews and Moseley 1990).
