First, the pond (?) Support. 1, select the appropriate pond water quality, adequate water is an essential condition for the pool ponds, the pond is best is the east-west rectangle, aspect ratio of 2: 1 or 3: 2, so long hours of sunshine, windy summer area , Is conducive to the increase of dissolved oxygen in water. Monoculture 鳜 fish pond area should not be too large or too small, too large fish is difficult to meet the fish, catfish individual differences in growth; too small is difficult to control changes in water quality. Generally 1000-3335 square meters is appropriate, the water depth of about 2 meters, the best sediment sandy loam, silt, humus less water should be thin, if micro-flow
