Squid (Astragalus membranaceus) is a cold-blooded fish with variable temperature. It has a strong adaptability to the environment. When the temperature drops below 10°C (growth temperature 15°C to 30°C), it rarely feeds and hibernates. In order to ensure safe wintering of carp, the water level of the culture pond should be raised to 70 cm to 80 cm to ensure that the water temperature at the bottom of the pond is above 0°C. If the pool surface is generally frozen, the ice must be opened every day to prevent the lack of oxygen in the carp. At the same time, on the basis of the original, deepen the water level to prevent freezing and increase the water temperature. Second, dry pool wintering method When the water temperature is below 10°C, drain the pool water, but ensure that the bottom of the pool is moist. In case of freezing cold, the surface of the pool should be covered with a layer of straw, wheat straw and other crop straws, insulation and antifreeze. The thickness of the cover should be at least 30 cm. The thicker the better. Third, the indoor wintering method When the temperature is below 10°C, the pond-raised carp is turned to winter. In a room with a pool or bucket of 1 kg of salmon and 2 kg of water, place the trout into the pond or bucket and change the water daily. To ensure that the room temperature between 2 °C ~ 5 °C. Fourth, the greenhouse wintering method When the water temperature in winter is lower than 12°C, the effect of overwintering in a plastic greenhouse or greenhouse is very good. In the greenhouse, the water level of the pond should be equivalent to the aquaculture water level, and the temperature in the shed should be between 2°C and 8°C. When the temperature is highest at noon every day, the ventilation holes of the greenhouse are opened, so that the air in the greenhouse is fresh. Ventilation holes are installed at the top of the greenhouse to prevent death from carp oxygen deficiency. Fifth, increase material wintering method Feeding squid feeds with high fat content before winter allows the squid to accumulate more fat for consumption during the hibernation. Feeds with high fat content include cocoons, cockroaches, and fly maggots. Feed them as much as possible.
