An analysis was made of the validity of the stock-recruitment curve-fitting exercise used to quantify the consequences of power plant operation on the striped bass population of the Hudson River. The use of a particular stock-recruitment model, called the Ricker model (Ricker 1954, 1958, and 1974), forms a cornerstone of the utilities' case. Based on estimates of a parameter termed ''alpha'' in the Ricker model, estimates of annual entrainment and impingement impacts of the Hudson River power plants on young-of-the-year striped bass are converted to estimates of long-term reduction in the equilibrium population size of adult striped bass. Results of the analysis of the exercise indicate that it is not valid.
