Brook trout are fish that live in beautiful places. They require cold, clean, oxygen-rich water to thrive, and a relatively undisturbed environment to reproduce. With a preference for clear, spring-fed lakes and stone-bottom streams, it's fair to assume that the presence of brook trout is a good indicator of a healthy body of water. 

They are aggressive predators that will sometimes out-compete native fish species for food resources. Their diet consists mostly of larval/adult aquatic insects such as stoneflies, caddisflies and mayflies, as well as terrestrial insects like grasshoppers, beetles and spiders. Their preferred menu goes on to include minnows, worms and frogs. Larger brook trout will sometimes even devour small rodents swimming across the water surface.
