Ecology of the paddlefish, Polyodon spathula (walbaum), in Old Hickory Reservoir, Tennesse, with emphasis on first-year life history and the effects of impingement at Gallatin Steam Plant on the population
During the period August 1974-July 1975, an estimated 4382 paddlefish were impinged on the intake screens at the Gallatin Steam Plant. An additional 9258 paddlefish were estimated to have been impinged from August 1975-May 1976. Practically all paddlefish impinged were age group 0 (young-of-year). Because the number estimated to have been impinged was higher at Gallatin Steam Plant than at any other TVA installation, and because paddlefish are infrequently collected in most fisheries investigations, TVA initiated a study to provide the data necessary for a better assessment of the effects of impingement mortality on the paddlefish population in Old Hickory Reservoir. This report presents results of these investigations and, because of the paucity of scientific literature, also serves as a state-of-the-art report on many facets of paddlefish biology. Specifically the study was designed to determine age structure, growth, movement, reproductive biology, year-class strengths, and abundance of paddlefish in Old Hickory Reservoir.
