† Populations may not be currently present.
Means of Introduction: The two suckers introduced into River Springs, California, were accidentally introduced from the San Gabriel River during the transplant of speckled dace Rhinichthys osculus (Miller 1968). The means of introduction in the other instances are unknown.
Status: Established in parts of California outside of its native range. Later visits to River Springs indicated the species did not survive at that site (Miller 1968).
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.
