Rainbow Trout

Appearance

Rainbow trout are a North American game fish that get their name from the beautiful colors that shine on their skin. Coloration of the fish varies widely in relationship to sex, habitat, and maturity. Colors on the back of the fish can range from brown to olive to dark blue. Fish have a pinkish stripe/band running the length of their bodies, with a silvery underside that fades to pearl white. They have small black spots on their backs, fins, and tail. Average mature fish are around 16 inches long and weigh between 2 and 8 pounds. (The largest rainbow ever caught, however, was in Canada and weighed 48 pounds.)

Habitat

Rainbow trout can easily adapt to various aquatic habitats and environments. They prefer cool freshwater streams with gravel bottoms and natural cover, such as downed trees and boulders. These fish prefer water temperatures of 55 to 60 degrees Fahrenheit, but can tolerate temperatures that vary from 32 to 70 degrees Fahrenheit.

Diet

Rainbow trout are opportunistic feeders and will eat anything from aquatic and terrestrial insects, to fish eggs, to small minnows, to crustaceans and worms.
