† Populations may not be currently present.
Means of Introduction: The source of these fish is either transfer by anglers or natural stream capture.
Status: Reported from the Sacramento drainage (Nevada) and the Feather and Rubicon rivers (California) in 1950, but more recent records are lacking.
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.
