Nonindigenous Occurrences: 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).

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: Unknown.

Remarks: This species has been listed as a federally endangered species since 1967 (U.S. Fish and Wildlife Service 1980b, 1993a). In its only known native habitat, the species faces several threats to survival including reduction or loss of water, surface water runoff, vandalism, and accidents (U.S. Fish and Wildlife Service 1980b, 1993a). A captive population was created in the 1970s in an artificial refugium consisting of a concrete-lined pond constructed below Hoover Dam, Clark County, Nevada (Lee et al. 1980 et seq.; U.S. Fish and Wildlife Service 1980b; Williams 1991). As a result of a greater food supply, and probably other factors, individuals in the refuge population differed from those found in the native habitat were larger and more brightly colored (Williams et al. 1988). According to Williams (1991), the Hoover Dam refugium population is no longer extant. A second refugium, the Amargosa Pupfish Refugium, was constructed in Ash Meadows and stocked with fish in 1980 (U.S. Fish and Wildlife Service 1980b; Sigler and Sigler 1987; Williams 1991).
