Means of Introduction: According to Sevon and Delany (1987), the introduction of tropical aquarium fishes and largemouth bass had decimated the populations of C. b. grandis in their native habitats at Hiko Spring and Crystal Spring in the White River drainage of Nevada. Blue Link Spring was selected by federal and state agencies to serve as a refuge for this endangered subspecies; the site is far outside the native range of the Hiko White River springfish and differs substantially from their native habitat (Sevon and Delany 1987). The original transplant took place in early 1985 when 59 fish were planted in Blue Link Spring; a second transplant, in late 1985, involved the stocking of 178 additional fish (Sevon and Delany 1987).
Status: Hiko White River springfish populations fluctuated widely in Blue Link Spring; however, the total number had increased steadily to an estimated 5,500 individuals by 1994 (Lujan 1994). Native populations in Hiko and Crystal springs compete with various nonindigenous fishes, and their numbers remain low in those sites (Clemmer, personal communication).
Impact of Introduction: Transplants have helped secure the long-term viability of this species.
