With the declining temperature, many farmers have shown higher efficiency, and the use of the shrimp from Macrobrachium praecox developed in large pools has been moved into plastic greenhouses or simple greenhouses. Although this method is more convenient in form, improper operation may result in a large number of deaths or mutual killings after the migration of Macrobrachium rosenbergii into the greenhouse. According to the experience of the past years, the following points should be noted during the process of removing sheds: 1. Before the large pool shrimps move into the greenhouses, they must be healthy and disease-free. The pre-transfer nutritional status is good. This is a prerequisite for holding. 2. Pay attention to the following operations during the moving process: After adding cages, you must go through oxygenation or flushing to allow the macrobrachal shrimps to have a recovery process, especially dry pond shrimps. It is advisable to allow Macrobrachium to enter the holding pool and swim out of the cage automatically. 3, holding pool according to the length of holding time, determine the stocking density, generally 1-2 kg per square meter is appropriate. 4. Temporary rearing shrimps are suitable for 30-60 tails per pound. According to the experience of previous years, they are too small and too large in specification to be competitive in the later period of sales and lose their sense of holding. 5. The water quality management of the holding pool should be strengthened. In addition to the normal oxygenation conditions, the air blower should be used to increase oxygen, and the machine can not be shut down for 24 hours, especially at night. 3-5 days to change the water once, the amount of control in 10% or less, keep the water temperature at 18-22 °C, more than 22 °C in time to film cooling, to prevent excessive temperature caused by a large number of shrimp shelling caused by slaughter, bait cast It is advisable to feed shrimp with a body weight of 3%, water depth control of 1 meter or more, transparency of 25-30 centimeters, and conditional pooling of some nets in the pool. 6, the holding time should not be too long, generally not more than 1 month.
