Natural History

Described as a voracious feeder that is capable of consuming large numbers of seasonal aquatic and terrestrial insects, the Brook Trout will also feed on zooplankton, crustaceans, worms and smaller fish. Brook Trout are typically found under cover of rocks and logs in cold water, spring-fed streams, rivers and lakes. Spawning in October and November, depending on water temperatures, the egg incubation period is 3-4 months before they hatch into sac fry, and will not begin to leave the redd until the yolk sac is absorbed.
