Creek chub, Semotilus atromaculatus


The creek chub is widely distributed and common in southern Canada and the eastern United States.

Native populations in Colorado are limited to the Platte River basin. This species has been inadvertently introduced into the Arkansas and Yampa river basins.

Creek chubs are generally found in small, clear streams and rivers and generally inhabit pools with large woody debris over sand and gravel substrates.

Creek chubs build nests in stream gravel for reproduction, and males develop a rosy coloration and pronounced spawning tubercles.

Maximum Length: 8-12" (20-30 cm).
