    Abstract
    Brackishwater milkfish culture in the Philippines is normally practiced at fish stocking rates of 2,000-3,000 ha-1 with fertilizers as the sole nutrient input. Supplementary feeding is not common. We stocked two 1-ha ponds with 6,000 fish and another two 1-ha ponds with 9,000 fish with an average weight of 2 g. The fish at each stocking rate were given diets with two different energy levels (2,950 and 3,265 kcal•kg-1) at 3% body weight, on the second and third month of culture. An average of 0.69 and 1.04 t were produced at 6,000 and 9,000 ha-1, respectively. Low temperature and dissolved oxygen levels appeared to limit the growth of milkfish masking the effect of dietary energy. The results suggest that supplementary feeding can have a marked effect on milkfish yield when stocking rates are 6,000 ha-1 or above.
