† Populations may not be currently present.
Means of Introduction: This species was intentionally stocked for the purpose of preserving an endangered species.
Status: The fish at Shoshone Ponds survived at least one month (Hubbs et al. 1974); however, the population later died out for unknown reasons (U.S. Fish and Wildlife Service 1983a). The population at Hot Creek Valley also failed (Clemmer, personal communication).
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.
