† Populations may not be currently present.
Means of Introduction: Introduced via bait bucket into the Rio Hondo and its tributaries. It is uncertain whether the Sapello Creek population originated naturally from stream capture via the Mimbres River or was introduced. Accidental introduction into the San Francisco River in the 1940s (Sublette et al 1990).
Status: Established in all locations in Arizona and New Mexico. Apparently extirpated in the Platte drainage, Colorado.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
