Abstract

The ability of the crayfish Orconectes immunis to graze submerged aquatic macrophytes was evaluated experimentally. Crayfish at densities greater than 140-150 g/m2 significantly decreased macrophyte biomass in all experiments. The rate of crayfish grazing in cages where significant decreases in macrophyte biomass occurred averaged 0.012 g of macrophytes consumed/crayfish/m2/day.
