Trout primarily feed on minnows, flies, mayflies, stoneflies, dragonflies and aquatic insects. Depending on their location, they may also feed on other water animals including smaller fish, their eggs and young, and aquatic macroinvertebrates such as crustaceans, crayfish, shrimp and snails.
Larger trout measuring more than a foot long feed on other fish, eels and large insects that fall into the water. Even mice are viable prey for large trout should they be found near the water to be caught. During the winter months, freshwater trout consume larval forms of insects off the bottom of lakes and streams. Trout, salmon and char are closely related fish.Learn More

Brown trout are vertebrates that are highly diverse from a genetic perspective, according to The Wild Trout Trust. British brown trout showcase more genetic diversity than any populations in the whole human race. While genetically distinct trout can spawn together and reproduce healthy offspring, many have preserved their unique traits for thousands of years. The species has between 38 and 42 pairs of chromosomes, while humans boast only 23 pairs.Full Answer >
