Fish Population Changes In Keystone Reservoir Fourteen Years After Striped Bass Introductions

During the 14 years after initial introduction, a viable striped bass (Morone saxatilis) sport fishery developed on Keystone Reservoir. Natural reproduction, first identified in 1970, continued through 1979 in tributary rivers. Selected endemic fish species showed no significant changes in standing crop estimates from cove rotenone studies 1971-73, 1976-79. Available prey-predator ratios (AP/P) showed a fluctuating availability of forage for small predators and ample prey for large predators.
