Apache trout (Oncorhynchus apache)

The Apache trout (Oncorhynchus apache) is a freshwater fish of the family Salmonidae. Native range: North America, Upper Salt River and Little Colorado River systems (Colorado River drainage) in Arizona, USA.

Biology

Inhabits clear, cool mountain headwaters and creeks (generally above 2500 m elevation), and mountain lakes. A 95% (stream km) reduction in range has resulted due to hybridization with Oncorhynchus mykiss and competition from Salvelinus fontinalis and Salmo trutta.
