摘要
Wild and hybrid strains of brook trout showed better rates of recovery and yield (kilograms of fish recovered per kilogram planted) than a domestic strain, during the 2 yr following planting, in 6 small oligotrophic lakes of the Laurentian Shield. Native brook trout and white sucker Catostomus commersoni had a significant impact on planted brook trout. -from Authors
