The cold snap is coming soon, and we must do a good job in the management of the cold snap low temperature period when we engage in #winter shed shrimp farming#. Farming One Point summarizes the following seven points to share with you. [Ratio]

　　1. The northern winter shed needs supporting equipment, mostly hot water circulation pipes; In the south, the shed can be built directly without heating equipment.

　　2. Ensure oxygen supply, reduce the water surface # aerator # open, increase the supply of bottom oxygen, and use the bottom oxygen heat to heat the water. It is estimated that ponds with bottom oxygen are 1-2 °C higher than those without bottom oxygen.

　　3. Do not cultivate bacteria if the water temperature is too low, you must know that fish and shrimp with low water temperature have no vitality, and fungi also lack vitality. Similarly, the water temperature is too low, and the material should be reduced. Winter shed shrimp should be managed around temperature.

　　4. After the spring warms up, #change the bottom# in advance to decompose the accumulated bait at the bottom of the pond that has not yet been treated. At the same time, strengthen ventilation and water disinfection to prevent shrimp disease. [China Like]
