Data is presented over a four-year period on population changes and dynamics in an 8,500-acre reservoir following rotenone treatment for selective shad reduction. Population data for four years prior to the shad kill is also discussed and analyzed. An analysis of the operation including methods, techniques, and results is presented. Records of fish stocking, creel census, age and growth and population studies after treatment is discussed and evaluated. Particular emphasis is directed toward two introduced species, white bass and threadfin shad. Data on the expansion and establishment of these introductions and the rapid growth rates encountered are presented. Year class dominance, reproduction, and fisherman success are compared, and the overall effect of selective shad kills on fish population changes is discussed and summarized.
