The pond covers an area of 3-5 mu and is rectangular in east-west direction. The depth of the pond is1.5m. The bottom material is hard, the thickness of silt does not exceed 10 cm, and the pool slope ratio is 1: 25, so the water source is sufficient. At the beginning of September, the bottom water in the pond was 10 cm, and the pond was cleaned with quicklime 150 kg. At the beginning of September, 60 cm of fresh water was added, and the water inlet was filtered with two 60-mesh screens to prevent impurities and enemies from entering. A circle of water peanuts was transplanted in the shallow water area about 1 m offshore. Before transplanting, it was disinfected with 5 mg of bleaching powder solution, and the water grass belt was fixed with nylon rope, accounting for 20% of the pond area. In the middle of the pond, 20 ~ 30 cm below the water surface, a knot-free summer flower net was set up to let the shrimps climb up and down. The net is 3 meters wide and arranged in 2 rows along the long side of the pond.
Second, cage setting.
Small net box bottom area 1 ~ 2 square meters, large net box bottom area 20 ~ 40 square meters, mesh 0.5 ~ 1 cm, box height 15 meters, open. Fix it with bamboo poles and put it 2 meters away from the pond inlet. There is mud at the bottom of the box. The bottom of the box is paved with 20 cm thick manure, and the water depth in the box is kept at 30 ~ 50 cm.
Third, fry and stock.
Green shrimp: put shrimp1.20kg per mu temporarily, and disinfect with 3% salt water before entering the pond, with the temperature difference of pond water not exceeding 5℃. At the same time, put 30 silver carp fingerlings per mu to adjust the water quality. Loach species: 50 ~ 60 loach species with 3 ~ 5 cm are stocked per square meter.
Fourth, shrimp pond management.
Feed feeding. Feed once every morning at 8-9 am and 5-6 pm; In the morning, feed one-third of the whole day's feeding amount, in the deep part of the pond, and feed two-thirds in the shallow water in the afternoon. The feed is mainly flour and bran, supplemented by fresh miscellaneous fish, and 6 kg is fed per mu every day. After 1 1 month, the water temperature drops, and feed 1 time every day. Feed less or not after 65438+February. You can also adjust it in time according to the specific situation and eat with 1 half an hour; Water quality control. 9-65438+ 10 month, keep the water depth about 80 cm, change fresh water every half month, and change water by 20cm； each time; 65438+ 10 The water temperature is high in the first half of the month, and the aerator should be turned on at noon every day. 1 hour. After 1 1 month, the water depth will remain around 1 m; Daily management. Patrol the pond every morning and evening, and patrol the pond in the middle of the night when the weather is abnormal to observe the activities, feeding and shelling of the freshwater shrimp. Spray limewater 1 time on the whole pond every half month (the concentration of limewater in the pond is 2mg/L) to prevent enemies from entering and shrimps from escaping when taking water and draining water; Management of box loach. Box loach can be fed with granular feed or artificial compound feed made of bran, silkworm chrysalis and earthworm, or with shrimp feed. The oral feeding amount is 3% ~ 5% of the loach's weight, which is divided into three times: morning, middle and evening. Brush the net clothes frequently at ordinary times to keep the water exchange in the cage, increase the dissolved oxygen and let enough bait organisms enter the box. Check the cage frequently and fill the hole immediately. Prevent the pollution of pesticides and fertilizers. And the invasion of enemy creatures.
