The establishment of a striped bass (Morone saxatilis) fishery in Lake Wateree, South Carolina, did not detrimentally influence largemouth bass (Micropterus salmoides) growth, abundance, or condition. There was no evidence striped bass introduction altered the clupeid, primarily Dorosoma spp., or the Lepomis ,Ipp. prey base. An important fishery was added, however, to the reservoir. The authors suggest care in applying results to other less fertile, prey deficient reservoirs.
