To do a good job of winter shrimp management is an important part of the development of shrimp culture, and its management work mainly includes:
1. Choose the wintering pool over the winter pool to use a pond that is more regular, shelters from the sun, and has a water depth of 1.2 meters or more. Put some aquatic plants such as water peanuts or willow branches, tiles, bricks, and other concealed objects in the pool. Each mu can be stocked with 150 kg - 200 kg of water plants and willow branches with 25 kg - 35 kg.
2. Reasonable stocking and restocking time In the middle and late December, choose sunny weather for stocking. The broodstock should select prawn with robust physique, complete appendages, and standard body size. The specifications are as follows: 200-500 females per kilogram of females, 140 males and 140 females, and a ratio of 2:1 males to females, 15 kg per mu. - 25 kg is appropriate. Juvenile shrimp wintering, acre stocking 2000 kg per kilogram -3000 juvenile shrimp 20 kg -40 kg.
3. Timely feeding in sunny and warm weather, when the water temperature is above 10°C, appropriate amount of rice bran, bean cake, crushed snail shellfish, etc., the amount of bait is 2% -4% of the shrimp body weight, less than 10°C can be reduced Cast or not cast.
4. Strengthen management During the entire wintering period, special management is required to regularly inspect the ponds to check the wintering and feeding conditions of the pro- and juvenile shrimps, keep the water fresh, and keep the dissolved oxygen adequately. Do a good job of preventing pollution and preventing predators. In the event of icing, ice should be broken or holes should be drilled on ice in order to prevent the suffocation of shrimp due to lack of oxygen.
