Gila trout (Oncorhynchus gilae)


This splendid golden-yellow trout, unique to the Gila River in New Mexico, has been depleted by clear-felling of watershed forests (causing erosion) and dam building leading to fluctuating water levels. Competition from introduced gamefish has reduced it still further, and the Gila trout is now confined to Diamond Creek and other streams. A conservation programme is already showing good results.
