Apache trout
(Oncorhynchus apache)
General data
Description
The Apache trout measures in length from 6 to 24 in (15–61 cm), and weighs between 0.4 to 6 lb (0.2–2.7 kg). It rarely exceeds 10 in (25 cm), but can reach up to 16 in (40 cm) in its native, headwater streams.
Apache trout are a yellowish-gold color with a golden belly and have medium-sized dark spots that are evenly spaced and that may extend below the lateral line and onto the dorsal and tail fins. The top of its head and back are dark olive in color, and it has the appearance of having a black stripe/mask through each of its eyes, due to two small black dots on either side of the pupil. There can be a throat mark below the lower jaw, ranging in color from yellow to gold.
Distribution
The Apache trout is the state fish of Arizona, and is one of only two species of trout native to that state, with the other being the gila trout (O. g. gilae). It natively lives in clear, cool streams in the White Mountains that flow through coniferous forests and marshes, but has been introduced into several lakes in the area. The Apache trout is native to the upper Salt River watershed (Black and White rivers) and the upper Little Colorado River watershed. Apache trout have been introduced into isolated streams outside of their historic range in the Pinaleno Mountains and the North Rim of the Grand Canyon.
