Inputs as related to output in milkfish production in the Philippines

Results show that inputs significantly related to milkfish output include stocking rates, pond age, operating costs, fertilizers, and farm size. Optimum stocking rates for milkfish frys and fingerlings, and application rates for organic and inorganic fertilizers are calculated. The more efficient farms were found to be those which are larger, privately owned, and located in climatically propitious areas. The authors conclude that a more intense application of inputs, especially in deeper ponds, would yield much higher output and profits. The available economies of scale offer great potential for Philippine milkfish culture. Farmers and policymakers could work to reorganize and restructure small units of production into larger, more efficient, and more profitable units without changing tenure status. A case for group farming is presented and related to the Philippine government's scheme of fishpond estate development. Improvements to existing assistance programs are also discussed.
