About this Species 

< Back
Name:Rainbow Trout
Scientific Name: Oncorhynchus mykiss
Range:Introduced in the cold tailwaters below dams in the Ozark and Ouachita mountains and into some large springs such as Mammoth Spring in northern Arkansas.
Habits and Habitat:Although natural reproduction occurs, most rainbow trout in Arkansas have been raised in hatcheries and stocked. Rainbows feed on crustaceans, aquatic insects and fish. Spawning, though rarely successful, occurs in fall and early winter.
Fish Fact: Large-scale stocking of rainbow trout began in the late 1940s when the construction of large, deep reservoirs in the Ozarks and their coldwater discharges wiped out native fish populations.
As A Group:Brown, rainbow, cutthroat and brook trout fishing has become immensely valuable to the state’s economy and provides many recreational benefits.
