The "brookie" or brook trout (Salvelinus fontinalis) was introduced to Montana from eastern North America in 1889. It too, was extensively propagated and stocked in the early half ... moreof this century, although seldom so today. Brook trout favor small, cold, headwaters streams and ponds, particularly those that are spring-fed. Brook trout are common throughout most of the western two-thirds of the state in all major drainages. Many an angler learned to fish for brookies as a kid. Spawning occurs in typical trout-like fashion with eggs deposited in a gravel redd during the fall. Brook trout are frequently able to spawn successfully in ponds which have upwelling springs. Brook trout will eat nearly any living organism, and larger fish can be voracious predators on other fish and even their own young. Brook trout are a handsome game fish in their own right, but indiscriminate stocking in mountain lakes has resulted in irreversibly stunted populations in many cases. Trophy brook trout up to 9 pounds have been taken in Montana waters.
