Zebra mussels were stocked in each cage (20000 individuals/m2) 14 days before male O. rusticus (20 individuals/m2) were stocked in each of eight enclosures. Densities of all sizes of zebra mussels were reduced in enclosures, with a total density reduction of 31% over the 28 days of the experiment, relative to the exclosures.
