young rainbow trout eat waterfleas and then aquatic (water) insects, like caddisflies, mayflies, and midges, to their diet. As they grow larger they include small fish, but continue to consume larval and adult insects. They also supplement the diet with other kinds of food, such as snail, leeches, fish eggs, sideswimmers,algae,cheese,and shrimp.when they move to saltwater they are considered steelhead trout.
