Common name: Devils Hole Pupfish
available through www.itis.gov
Identification: La Rivers (1962); Sigler and Sigler (1987); Page and Burr (1991).
Size: 3.4 cm.
Native Range: Devil's Hole in central Ash Meadows, Death Valley National Monument, Nye County, Nevada (U.S. Fish and Wildlife Service 1980b; Page and Burr 1991).
This species was introduced into five, supposedly suitable, artificial refuges widely scattered over the deserts of California and Nevada (Soltz and Naiman 1978). These artifical refuges are large concrete tanks designed to simulate natural conditions in Devil's Hole. Several refugia were constructed close to (but isolated from) natural springs, and were given the name of the spring (e.g., Point of Rocks Spring refuge; Echelle, personal communication).

† Populations may not be currently present.
Means of Introduction: This species was intentionally stocked to create another population of a restricted endangered species. Point of Rocks Springs refuge was stocked with 16 fish in 1992. The population declined to 5 fish and was augmented with another 16.
Status: Early introductions into spring habitats failed to become established (Soltz and Naiman 1978). Recent introductions have been made into artificial refuge habitats, but current status is not certain and available information is somewhat conflicting.
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.
