Abstract: The ecological fish load were calculated under the condition of class II water quality, according to the yield of filter fish in the reservoir area of Ankang and in a proportion of 1 to 3, and to comparison of the calculation results with the phosphorus content in water. Results show, set the cage depth 3m, the unit of water ecological fish carrying capacity is 193.44g/m3, the total output control for 10.47t × 104 in reservoir area of An-kang. When the net raising yield is 100kg/m3, the control area is 1.93 per thousand, and the yield per unit area is inversely proportional to the ecological farming area.
