Range and Identity
Xyrauchen texanus is native to the Colorado River basin. Present records can include stocked fish, so occurrence should remain separate from evidence of successful natural reproduction. The distinctive ridge is useful for identification, together with the fish’s overall sucker form and locality.
Habitat and Behavior
Adults use river and lake environments, including deeper eddies and backwaters. After spawning, larvae drift toward quiet, warm, shallow backwaters or floodplain wetlands. These connected habitats support different stages, making a description limited to the adult’s deeper water incomplete.
Food and Life History
Spawning commonly occurs on cobble bars, with timing influenced by water temperature and flow. The agency account describes individuals exceeding three feet without specifying a formal length convention. Its inconsistent pound-to-kilogram conversion is not repeated as an exact maximum weight. Individuals can survive for decades.
Field Note
Distinguish a stocked adult record from observations of young produced locally. Both matter, but they answer different questions about a population’s continued reproduction.
