Notes:
A production function for catfish in cages was estmated by combining data from a survey of producers in Alabama with data from experimental studies in Texas, South Carolina, and Alabama. Explanatory variables in the quadratic model included cage stocking density, fingerling size, length of growing season, feed conversion rate, squared and cross-product terms, and dummy variables for data sources. Model R2 was 87%. Profit-maximizing stocking densities were calculated for varying levels of growing season duration, fingerling size, fingerling price and market price. Optimal stocking density was shown to be most sensitive to length of growing season.
