Abstract
The rate of impingement of fishes on the vertical traveling screens at Peach Bottom Atomic Power Station Units No. 2 and 3, Pennsylvania, was determined from November 1973 through December 1975. At Unit No. 2, 14,383 specimens (157 kg) of 33 species were impinged in one hundred seventy‐four 12‐h sampling periods. At Unit No. 3, 40,046 specimens (1,153 kg) of 33 species were impinged in seventy‐one 12‐h sampling periods. Channel catfish, Ictalurus punctatus, white crappie, Pomoxis annularis, and bluegill, Lepomis macrochirus, were impinged most frequently. Impingement was highest in November through April. Impingement was highest during the start‐up phase of each unit. Multiple regression analysis revealed that the intake water temperature, daily river flow, and pond elevation accounted for 32 to 73% of the variation in the impingement of fishes. Winter (January through March) mortality of white crappie and bluegill at the screens was equal to that caused by a few anglers over the same period. The design and placement of the screens, preceded by relevant behavioral studies were, in part, responsible for minimal fish losses due to impingement at Peach Bottom.
