The results of analyses designed to develop model fishery compartments and associated fish population rate coefficients on a regional basis for use in reservoir ecosystem modeling are presented. Emphasis is directed toward development of regional rate coefficients for the United States corresponding to major geographical drainage areas. Fishery data will be incorporated in the reservoir ecosystem model currently being developed by personnel of the Environmental Effects Laboratory, U.S. Army Engineer Waterways Experiment Station. Known physical, chemical, and fishery conditions in 187 Corps of Engineers (CE) impoundments larger than 500 acres are described. Multivariable equations are presented that allow estimation of standing crop and sport fish harvest in CE reservoirs. Data were also reviewed and summarized on the ecological growth and assimilation efficiencies of fish, food consumption rates, respiration rates, temperature tolerances, half-saturation constants for growth, and chemical composition.

This text analyzes the structure of fish populations in inland reservoirs, based on absolute values of their mass. The structure of population and its changes have been examined in seven fish species from small lakes, two from large lakes and seven from large reservoirs in plains. Special attention has been paid to the main indicator of the structure of population-correlation between the age of ichthyomass and mass maturation.
