The key points of adult crab production after snow

1. Pond clearing. Before stocking, the ponds must be cleaned, and after the snow the ponds must also be reinforced to remove excess silt. About 15 days before the stocking of the crabs, the ponds were thoroughly cleared. There were two methods for clearing ponds: dry method and clear water method. General dry clearing pond uses 75 kg of lime per acre, and the whole pool is splashed after melting. The water clearing pond is used only when the pool water cannot be discharged mostly. The specific amount can be controlled flexibly according to the depth of the pool water, and it can ensure that the enemy can kill the water.

2. Reinforce anti-escape facilities. Thorough anti-escape facilities should be built around the cultivated crab ponds to prevent crabs from escaping. The inner wall of the anti-escape facilities should be smooth, plastic film, iron plate, aluminum plate, etc. are commonly used.

3. Water grass antifreeze. Farmers who have planted aquatic plants such as Elodea are required to prevent freezing of aquatic plants. The specific method is to ensure that the water level is higher than that of aquatic plants and the ice layer is above the aquatic plants.

4. When the temperature of the refrigerated crab species is temporarily below 0°C, or when it is snowy, no crab species can be caught, transported, or stocked to prevent frostbite from frostbite. Wait for the weather to warm up, and when the temperature is above 5°C, perform the relevant operations for crab species.
