The Reservoir Committee, Southern Division, American Fisheries Society, undertook to measure the influence of stocked predator fishes on existing fish populations and sport fishing in selected reservoirs through a coordinated interagency study. Field data collection consisted of (1) fish population biomass estimation, (2) limnological survey, and (3) sport fish harvest estimation, with data being collected in 1972 and 1973. Twenty-six reservoirs, totaling 368,000 acres, were included in the project. The work plan used to standardize field data collection is described. Six years were required to plan, execute. analyze, and publish the results.
