1 Construction of a flow pond The aquaculture pond can be built indoors or outdoors. Each pond has an area of ​​2 to 5 m2, a depth of 24 cm, a rectangle, brick paving, a single brick erected side by side, and a concrete trowel. The walls are set around to prevent fleeing. The two ends of the pool are set at 20 cm above the bottom of the pool, respectively, into the drain outlets, and the nets or grids with appropriate apertures are installed. The sand is laid at the bottom of the pool. When building multiple pools, they can be single-linked. Upstream, it is necessary to build a water reservoir, and after installing the regulating water valve and opening the valve, it is required that the pool water flow through the pools one by one in order and finally be discharged. 2 Seedlings are selected from artificial or natural collections. Physical requirements are strong, uniform specifications, bright colors, no trauma, specifications 25 to 30 grams per tail, 100 to 150 tails per square meter can be placed before the application of 30 to 40 g/L of salt water or high manganese into the pool Potassium acid disinfection. 3 feeding and management 3? 1 Astragalus feed can be fed quail, fresh fish, shrimp, etc., can also be fed artificial compound feed. 3? 2 seedlings into the pool 3 days after the feeding and domestication, domestication period of about 15 days. Begin to feed late in the evening, and then gradually advance to 14 to 15 o'clock in the afternoon or about 10 o'clock in the morning, the daily feeding amount is 6% to 7% of the overall weight of the carp, which is divided into two feeds in the morning and evening. It is also necessary to implement the "Four Sets" for the feeding of the yellow cricket. 3?3 Microfluidic water can be used for long-flow type or intermittent type, and the flow can be adjusted by adjusting the discharge valve of the reservoir. The water depth of the culture pond is maintained at 15-20 centimeters for a long time. It is best to plant some aquatic plants or shady artificially in the pond during the summer season. 3?4 Once every half a month, open the large water storage valve and increase the water flow in the culture tank. Starting from the upper pool, use a tool to agitate the bottom sand to flush the residual baits, feces and other contaminants that are adsorbed on the sand. Start up and discharge into a pool in turn, until the rear of the aquaculture tank. 3?5 It is necessary to regularly patrol the pool to observe the water quality and water temperature conditions and pay attention to cats and mice. 4 Prevention of jaundice in rickets is not easy to detect, so prevention is the main reason. In addition to the larvae before the release of seedlings to be sterilized, during the breeding period generally every 15 days around the whole pool sprinkle lime, the amount of 5 ~ 10 g / m? In the onset season, regularly apply low-level liquids such as bleaching powder of 0 to 1 g/m3 or trichlorfon of 0.2 g/m3 to the pond or 0 to 7 g/m3 of copper sulfate in the pond. Wait. Pay attention to the need to close the inlet valve when the drug is administered to stop the flow of water in order to achieve the effect of the medicated bath to prevent diseases.
