Range and Identity
Catostomus fumeiventris belongs to the Owens drainage fauna. Introduced records are reported from June Lake and the Santa Clara River system, but those should remain distinct from native occurrence. A California locality alone is not enough to decide whether a population is native.
Habitat and Behavior
Adults use creek pools and runs over varied bottom material. The range from silt to rock means the immediate collection site is more informative than a single assumed substrate preference. Local current, depth and surrounding cover should be retained when they were observed.
Size and Life-History Records
The maximum reference is fifty centimeters total length, with a common reference of 30.9 centimeters. No independent maximum weight is supplied by the checked summary. Feeding and reproductive details from another Catostomus species are not used to fill gaps in this species-specific account.
Field Note
Attach native or introduced context to a record outside the Owens system. The same correctly identified fish can have a very different population history elsewhere.
