Means of Introduction: Bait bucket release. It was apparently introduced in 1968 into the Pecos River system of New Mexico from the Canadian drainage (Sublette et al. 1990) and spread downstream to Texas.
Status: Established and very abundant in the Pecos River in New Mexico and Texas. Bestgen et al. (1989) stated that the species is now the most abundant fish in the Pecos River and accounted for more than 80% of the catch at some sites. Tyus et al. (1982) listed it as an incidental record in the Colorado River basin, a category that was defined as occurring in very low numbers and known from only a few point collections.
Impact of Introduction: The extirpation of the native Rio Grande silvery minnow, Hybognathus amarus, from the Pecos River has been attributed to wholesale displacement by introduced H. placitus through competitive exclusion (Hoagstrom et al. 2010). Hybognathus amarus was last taken in the Pecos River in 1968 (Bestgen et al. 1989).
