The Rainbow Trout (Oncorhynchus mykiss) is a member of the Salmonoid Family, and the ocean going (anadromous) form are known as Steelhead. Rainbow Trout have a varied diet eating a mixture of smaller fish ad insects, almost from the time that they are born. As a rule of thumb you might hear that as Rainbow Trout get older they consume more fish than insects, however insects are always a stable part of their diet.
