Net cage breeding

In a well-watered pond, a net cage is set up to educate the eel, and the upstream and downstream eel of the mud eel is conducive to oxygenation, and it can prevent the death of the eel's entanglement. This farming model is easy to manage, effective and efficient.
1. Environmental conditions. The pond water quality is required to be free of pollution, the water level is stable, the water depth is guaranteed to be over 1 meter, and the area is 1 mu to 20 mu.
2. The cage settings. Choose a dense mesh polyethylene net to make a cage. The size of the mesh is based on the principle of not squeaking and squatting and facilitating the exchange of water inside and outside the cage. The area of ​​a single box does not exceed 20 square meters, and the specifications are generally 5 meters to 7 meters in length, 2 meters to 3 meters in width, and 1.5 meters to 2 meters in height. The cages are fixed along the pool side with bamboo rafts. The tank mouth is 0.5 meters to 0.6 meters above the water surface. The distance between the box and the box is 1.5 meters. The total area of ​​the cage does not exceed 10% of the pond area. For the first 7 days to 10 days before stocking, the new cages are soaked in water and a layer of algae biofilm is attached to the surface of the nets to avoid scratching the carcasses. The exposed or disinfected soil is thrown into the cage at a thickness of about 0.2 meters so that the earthworms and cockroaches can infiltrate into the soil during the winter. Transplanting water peanuts in the box covers 70% to 80% of the cage area.
3. Seedling stocking. The ponds were stocked before they were released for breeding.é³ é³…, é³… é³… ～ ～ é³… é³… é³… é³… é³… é³… å‡å¯ å‡å¯ å‡å¯ å‡å¯ å‡å¯ å‡å¯ è§„æ ¼ è§„æ ¼ è§„æ ¼ è§„æ ¼ , , , , , , , , , , , , , , , , , , , , , , , , , , , , As early as possible stocking, in order to help improve the specifications out of the box. Each square meter of cage stocking size is 25 grams of 2 grams of Astragalus, 0.5 kg of loach; or 50 grams of astragalus stocking specifications of 3 kg to 4 kg, 1 kg of loach. Three to five days before stocking, the water peanuts and water in the box were disinfected with a bleach solution. Seedlings, lotus root seed disinfection can be soaked with 10ppm of methylene blue aqueous solution for 10 minutes to 15 minutes or with 20ppm potassium permanganate solution bath 5 minutes to 10 minutes, you can also use 3% to 4% salt solution soak 3 minutes to 5 minutes .
4. Feed feeding. It is better to use fresh feed such as small fish, shrimp, cockroach, fly maggot, silkworm cocoon, pig blood, and animal internal organs. Muddy feed can be solved by fertilizing the water and it needs to be fed properly. Start feeding less, then gradually increase. Feed twice a day, once in the morning from 8 to 9 in the morning, and once in the afternoon from 5 to 6 in the afternoon. During the breeding period, the daily feeding amount is generally 8% to 10% of the total weight of the pupa and pupa. The feed should be fresh and the quality should be relatively stable. One to two food counters are provided for every 10 square meters of cage. The food table is 0.2 meters away from the water surface. Feed should be placed on the food table.
5. Daily management. Adhere to the inspection box sooner or later, prevent escape, prevent rat, guard against theft, and prevent flooding, timely remove the over-prosperous water peanut in the box, and prevent it from escaping outside the box. After November, there is no soil layer in the box. The peanut can be thickened to 0.3 meters, and then heavy weights can be used to sink the larvae and clams into winter.
