Arizona State Fish
Apache Trout (common name)
Oncorhynchus gilae apache (scientific name)
This native trout from the White Mountains of Arizona is gold in color with a dark olive head and back, dark spots all over, and a black stripe across the eyes. The Apache trout lives in clear, cold streams, lakes, and marshes. The U.S. Fish and Wildlife Service and the White Mountain Apache Tribe have been working to increase the population of the Apache trout since the 1940s, and although it remains endangered, their efforts have increased the species’ numbers. The Apache trout was adopted as the state fish of Arizona in 1986.

The Apache trout eats flies, fly larvae (particularly the Caddis fly), mosquitoes, aquatic insects, worms, small fish, and other small aquatic organisms.
Spawning frequency: March to Mid-June
Mating behavior: Distinct pairing
Egg laying: The female constructs a nest-like depression called a redd in loose gravel and lays 70–600 eggs. The males then swim by and fertilize them. The eggs hatch after 30 days, and it takes up to three years for the fish to fully mature.
