California Fish Species
|Scientific Name||Catostomus fumeiventris|
|Life History||Owens suckers occupy waters in southeastern California and specifically in the Owens Valley. The species has been introduced into June Lake (Mono Lake Basin) and the Santa Clara River drainage (via the Owens Aqueduct). They are primarily found in long stretches of soft-bottomed runs in cool-water streams. They also inhabit the bottoms of lakes and reservoirs. Owens suckers feed at night on a diet of aquatic insects, algae, detritus, and organic matter. Their life history is similar to the Tahoe sucker and they spawn from early May through early July. Like other suckers, Owens suckers probably spawn in groups over gravel substrate. Larval suckers become juveniles at a total length of 19-22 mm and hide under cover along stream margins and in backwaters.|
|Watershed||Crowley Lake Watershed, Mono Lake Watershed, Owens Lake Watershed, Santa Clara Watershed|
Please note, watersheds are at the USGS 8-digit Hydrologic Unit Code (HUC) scale, so they often include a lot of sub-watersheds. If a species occurs in any sub-watershed within the HUC, the species appears within the HUC. Link to an EPA page that shows HUCs.
