Abstract
Ponds and lakes in the Adirondack Mountain region of New York State that contain brook trout Salvelinus fontinalis are generally infertile and trout production is low when brook trout have to compete with non-trout species. Standing crop estimates for seven waters with mixed-species associations ranged from 50 to 100 lb/acre; suckers Catostomus spp. were a major component of each assemblage, Brook trout standing crops were under 1 lb/acre in all but one water and were particularly low where yellow perch Perca flavescens were present. Following reclamation, during which major competing species were removed, brook trout were restocked. Subsequent estimates of brook trout standing crops ranged from 5 to 16 lb/acre, and good trout fishing prevailed where previously there had been little or none.Keywords
