General Description

Rio Grande Sucker (Catostomus plebeius) is a small (10-15 cm) fish that occurs from Colorado and New Mexico south to Chihuahua, Durango, and Zacatecas in Mexico. In New Mexico they are primarily found in the Rio Grande and Mimbres River drainages. They inhabit small to medium rivers and are usually found in moderate to high velocity sections of the river that have gravel and cobble substrates and clear water. They spawn in spring and, depending on conditions, will sometimes spawn again in the fall.
