摘要

Black carp consume large quantities of mollusks but food consumption and growth rates have not been studied. Consumption and growth of two sizes of fish fed formulated and natural diets at 20, 25, and 30 C under laboratory conditions were measured. Consumption and growth of fish fed formulated feed increased as temperature increased but followed a convex relationship for fish fed a natural diet. Metabolic and fecal production rates were determined for fish at each temperature. This information was used to develop balanced energy budgets for black carp. Bioenergetic simulation models were constructed to predict consumption and growth in natural systems. Fish inhabiting the Tennessee River and Lake Erie grow faster than fish in other select natural systems of the eastern United States and probably provide a highly satisfactory thermal regime.
