Ecology of Gila trout in Main Diamond Creek in New Mexico

The Gila trout (Salmo gilae) was once widely distributed in headwaters of the Gila River in New Mexico. Introduction of exotics and changing climate have resulted in marked decline of the species. Study objectives were to obtain information that would provide a base for management and preservation of Gila trout as a potential sport fishery resource and as a unique species. Information on the ecological status of Gila trout and its taxonomic relationship with closely related trouts was of primary concern in reaching these objectives. Technical papers.
