The Trout is a salmonoid fish. Most other trouts live exclusively in rivers and lakes, others spend 2-3 years in the sea and then return to fresh water to spawn(to reproduce). Their classification is oily fish. Except humans, bears, eagles and some other eat trout as well.

Because The Trout live in a lot of different habitats, they can have couple of  different colors and patterns. These colors and patterns form as camouflage, based on surroundings and will change as the fish moves to different locations. 

Trout feed on other fish, and aquatic invertebrates (mollusks, flies, dragonflies) and zooplankton. Bigger trout species feed exclusively on other fish, up to 1/3 their length, where they are available. Trout may also feed on small animal parts, eels and shrimps.

Trout's preparation for cooking should be simple in order for it's flavor to be prominent, trout has very few bones to remove before cooking and it's scales can be left on. As for recipes any salmon recipe is suitable for a trout as well, smoked is especially good.
