Overview
The Apache Trout (Oncorhynchus apache) is Arizona’s celebrated state fish and one of only two trout species native to the Grand Canyon state. Rebounding from the very brink of extinction through historic cooperative tribal and federal conservation, this stunning salmonid is famous for its rich golden-yellow to copper body, bold black leopard spots, and a distinctive black horizontal eye mask that gives it a pirate-like appearance.
Biology and Physical Characteristics
Oncorhynchus apache displays an unmistakable golden-yellow to deep butter-yellow body coloration with a lighter yellow or white belly. Its back and flanks are generously sprinkled with medium-sized, dark circular spots that are evenly spaced. The dorsal and anal fins are boldly tipped with brilliant creamy-white edges, while two black spots flanking the pupil create the illusion of a horizontal black stripe running directly through the eye.
Behavior and Ecology
A cold-water stream specialist, the Apache Trout thrives in pristine, shaded mountain creeks fed by snowmelt and mountain springs in the White Mountain Apache Reservation. It feeds predominantly on drifting aquatic insect larvae and terrestrial insects like grasshoppers that tumble into the water from overhanging alders, spawning in early spring in clean, oxygen-rich gravel beds (redds).
Conservation and Human Impact
Once reduced to fewer than 30 miles of isolated headwater creeks due to hybridization with introduced rainbow trout and overgrazing, the Apache Trout achieved legendary conservation status in 2024 when it became the very first sportfish in American history proposed for full recovery delisting under the Endangered Species Act thanks to dedicated White Mountain Apache Tribe leadership.
Interesting Factoid
The Apache Trout made global conservation history in 2024 by becoming the first native trout in the United States to successfully recover from the brink of extinction and be removed from the Endangered Species Act endangered list.
