Brook Trout

(Salvelinus fontinalis)

Description
The brook trout is one of the most colorful of the trout species. The brook trout is actually a char, characterized by light spots on a dark background. The back is dark green with pale wavy lines; some people these as worm-like markings. The sides are a purple sheen with blue-haloed red spots. There are no black spots on this fish. The pelvic, pectoral and anal fins have white leading edges. Originally native to the eastern U.S. and Canada, the brook trout was introduced into Idaho waters in the early 1900's. They are now found in many of our streams and lakes.

Life History
The brook trout spawns in October and the eggs hatch in the spring. They can first spawn when they are 18 months old and only three inches long. This feature causes many brook trout populations to overcrowd their habitat resulting in individuals becoming stunted in size.

Feeding Habits
The diet of the brook trout is extremely variable as it includes invertebrates, insects, and fish. Because of this varied diet, many different fishing techniques can take brook trout.

Angling Techniques
Small spinners or spoons are often quite effective, as are both wet and dry flies. Worms also work quite well. To catch brook trout, the lure should be placed close to cover, such as submerged logs or undercut banks. Once the fish has been hooked, it is important to get it into open water as brook trout are notorious for tangling the angler's line around logs and rocks.
