The Little Trout series are three justly famous trout catchers

A Pennsylvania angler, Samuel Slaymaker, created three small bucktail streamers that are intended to imitate young trout: the Little Rainbow Trout, the Little Brown Trout, and the Little Brook Trout. Adult trout are cannibals and have no hesitation in eating their own young. These small streamers are intended to imitate young trout and offer a tasty meal to a larger trout. They're not hard to tie and they are effective.
