1. Pond construction can choose to build a fish pond in the open space in front of and behind the farm house. In order to prevent the pond from drilling holes, the wall of the pond should be cement or brick. If the earth pond is used, the wall should be thickened and firm, and the bottom of the pond should be paved with gravel or clay soil. The fish pond area is generally 80 ~1600 square meters, the dike 1.5 meters, the water depth of the pond is 0.6 ~ 0.8 meters, the bottom of the pond is inclined to the drain, and the wall of the pond is made into several caves. Pipes (cement or plastic) with a diameter of 13 cm and a length of 5 meters are placed in the pond to facilitate fish. Plant duckweed, etc. with the total area not exceeding 1/2 in the pool water.

2. The stocking period is generally from March to August every year, and the stocking density is 80 ~100 fish/m2 for fish with a size of 3 ~ 5cm, and it can be increased to100 ~ 200 fish/m2 if there is sufficient feed and running water.

3. Feeding pond fish is omnivorous, which can be fed with animal feed or plant feed. In order to adapt to the feeding habits of pond fish, the feeding time should be once in the morning and evening, or once in the evening. The feeding amount is appropriately increased or decreased according to the climate, water quality and feeding intensity. Generally, the daily feeding amount is 3% ~ 5% of the total weight of pond fish.

4. Prevention of diseases of pond fish is less, and the common diseases are mainly printing disease and dermatomycosis. In the former, circles form oval red spots on the fish body, like printing; The latter is covered with white hair and yellow mud on the hair. Treatment: printing disease can be used 1ppm bleaching powder spilled in the whole pool; Dermatomycosis can be sprinkled with 0.08% salt solution in the whole pool. At the same time, it is necessary to prevent the invasion of water snakes, frogs, rats and fierce fish.

5. The catch and transportation of pond fish grow rapidly, and it can reach the commodity scale of120g after 3-4 months. After fishing, put the fish in a small cement or brick pond1~ 2 days, so that it can discharge intestinal food and remove muddy smell, and then transport it to the market. For long-distance transportation, fish should be packed in nylon bags filled with oxygen.
