ESTIMATE OF THE OPTIMUM PRODUCTION OF FISH FARMS IN THE SEASON 2012 IN SALAH-ALDEEN GOVENORATE

Abstract

In this research, the production and cost function of farms fish where conducted from random sample included of (%19.4) of total fish breeders in Salah Al-Deen governorate. The data were obtained by a questionnaire, for this purpose, data collection to (70 ) fish farms, the linear cost function, quadratic and cubic models were applied, the quadratic function was chosen as the best according to statistical and economical cietera. From this, after function the production which minimizes the cost was calculated and it was mounted to 2.95 ton/donum, while the production which maximize the profit amounted to 3.20 tons\ donums. The optimum area was conducted too and was amounted to 1.711 donum, the production was applied, between the production per donum as dependent variable, the long-run cost function was conducted from the production function, and it was found that the price elasticity for long run was mounted to 0.385. In this research, and in order to expand the production of fish it was recommended to subsidize the price of forage, medicine and to expand the loans in order to expand the production to the limit of self-sufficient.
