Rio Grande chub

Overview

The Rio Grande chub is a species of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, chubs, Eurasian minnows and related species. This fish is endemic to the United States. It inhabits the upper Rio Grande and Pecos River systems in Colorado, New Mexico and Texas. The Rio Grande chub is native to most of its current range including all three of the states it can be found in. There are non-native populations that currently inhabit Coyote Creek, the Mora River, the Sapello River and other areas in New Mexico. There are currently no studies showing how the Rio Grande chub is impacting waterways in its non-native range. It has also been proposed that this fish is native to the Canadian River in New Mexico but this has not been proven. It is possible it was introduced there. Natural hybridization can occur between the Rio Grande chub and the longnose dace.
