River Carpsucker

River Carpsucker

The River Carpsucker (Carpiodes carpio) is a native freshwater species found statewide across Texas, distributed throughout major drainage systems.

This member of the sucker family (Catostomidae) is challenging to catch due to their skittish nature and bottom-feeding behavior.

Scientific Name: Carpiodes carpio

Physical Characteristics:

Distinguished by its deep, somewhat compressed body with an arched back, olive-brown dorsal coloration fading to silver with golden tints on the sides and white belly, large scales, and distinctive projecting lower lip.

Adults typically reach 12-18 inches and 1-3 pounds, though specimens over 10 pounds are occasionally caught.

What to know

Habitat Distribution

They prefer large rivers and reservoirs with sand or silt bottoms and slower-moving currents, though young fish are commonly found in smaller streams and tributaries. Found statewide across Texas.

Key Locations

Major drainage systems including the Red River, Sabine Lake, Galveston Bay, Brazos River, Colorado River, San Antonio Bay, and Nueces River. Specific Texas locations include Lake Texoma, Lake Diversion, the Brazos River, Sulphur River, and South Sulphur River. Productive locations include the lower Brazos River pools and runs, oxbow lakes connected to main channels, and the channelized South Sulphur River during low-flow conditions.

Specific Spots

Target quiet, silt-bottomed pools in rivers with low to moderate gradients, areas with large woody debris, and deeper waters near structures. In Texas reservoirs, look for them in water up to 12 meters deep over sand or silt bottoms.
