1. The choice of pond. The pond should be selected where the water source conditions are good and the water is convenient for drainage. The pond is best east-west and there are no tall crops around. The area is determined by the scale of cultivation, and the depth of the pond is about 1.5 meters. After selecting the pond, the clear pond is dried with 150 kg of lime per acre from January to March, and exposed to sunlight for 7 to 10 days. If a new pond should be developed after the pond is developed, it shall be sprinkled with 150 kilograms of quicklime per acre. After the pond is flooded, 1 to 2 herrings per mu, 10 grass carp, 20 bullhead fish, and 30 whitefish are stocked. 2. Casing layout. First, press a cage with two to four long wooden studs with a length of about 2.5 meters to form a row in the pond. Then fix the wire from head to tail on the stake to facilitate fixing the cage. The cage should be made of polyethylene knotless warp-knitted mesh to a size of 5 meters in length, 2 meters in height, 1.5 meters in height, or 4 meters in length, 2 meters in height and 1.5 meters in height, and then the cage is fixed on the wire. When hanging cages, the vertical distance is 2 to 3 meters, and the horizontal distance is 1 to 2 meters. The cages should be hung around 0.5 meters from the water surface. After the cage is hung, put the water hyacinth into the cage. The water hyacinth takes up about 2/3 of the cage area. (Disinfect the water hyacinth before disinfecting with the disinfectant). 3. Seed delivery. The best choice for the seedlings is the local jaundice with large spots. Generally, the best time to invest seedlings is from early June to early July. When investing seedlings first understand the weather, it is best to choose the recent rain-free weather. Net cages should be disinfected with lime or disinfectants 2 to 3 days before seedlings. Seedlings generally choose 0.4 to two to about two healthy jaundice. Before the seedlings go out of the box, soak them with 100% poison or Weikang. In general, cages raise 1 to 1.5 kg of seedlings per square meter. 4. Feeding management. Seedlings are placed under the box and observed for three days. If there are dead seedlings, they should be removed immediately. On the fourth day, fresh scorpion fish or small junk fish were used. After processing with a mincer, the fish was put on a mash and the scalloped puffed feed was evenly mixed until it became ready for training. Usually put 2 to 3 food stations inside a cage. After eating, observe the feeding situation of Astragalus. After observing the yellow astragalus on the next morning, if you have finished eating, increase the amount by a little. If you don't finish the meal, remove the remaining feed. You should observe it every morning and be aware of it. Slowly add food to 50 kg jaundice and eat about 4 kilos of fresh scorpion fish and about 2 kilos of puffed feed. Add 8 to 5 kg of scorpion fish and 3 to 4 pounds of puffed feed to 50 kg of jaundice from August to September. After the end of September, if the temperature drops, the amount of extruded feed is slowly reduced until it stops. In August-September, where there are conditions, you can change the water regularly to improve the water quality. 5. Disease prevention and control. There are currently no specific drugs for jaundice diseases, mainly prevention. The general jaundice is disinfected with quicklime water before it is placed in the lower box, and then once every half month, it is neutralized with trichloroisocyanuric acid powder or one hundred poisons. During training, you can add a little stimulating agent to electrolyze multi-dimensional and tetra yellow powder. After each half-month, add four yellow powders and vitamin C or electrolytic cubes. To enhance the jaundice constitution. After half a month, the eel's feeding was normal, and the insects were killed and the internal parasites were disinfested with the insects, and the parasite was driven every other month. After driving parasites, add Gantai to astragalus for oral administration for five days or so. After liver and liver is served, use intestinal fistula or Hunoo to prevent bacterial diseases. In August-September, a large amount of microbiological agents can be added to the feed to increase water quality. The addition of microbial preparations should be separated from the disinfectants and antibiotics by about 3 days.
