How do crayfish survive the winter?

Crayfish is a limited delicacy every summer, but many city restaurants have their own breeding bases and can eat crayfish in other seasons. Although it is not as big as summer, it is full. So how to raise crayfish for the winter? Let's have a look!

First, how to raise crayfish for the winter

Farmed crayfish should create a relatively warm environment in winter to maintain the temperature of the pool water. Patrol the pool twice a day, find abnormal and take countermeasures in time.

Daily management of crayfish

(1) bait at the right time. Feed more animal feed before overwintering to strengthen the physique and improve the survival rate in winter. During the overwintering period, the lobster does not look for food, but when the weather is sunny and warm, the lobster leaves the cave and forages a small amount of food, which can be fed with animal bait such as miscellaneous fish and shrimp, conch clam meat and animal viscera to replenish the body nutrition.

(2) improve the water quality. During the overwintering period, the water level in the pool should be kept above 1.5 meters to maintain the water temperature of the pool. If the water level is too shallow, it is necessary to replenish the water timely to prevent the lobster from frostbite to death; if the water quality is too fertile, change the water at the right time, keep the dissolved oxygen in the water above 4 kg / L and the transparency above 40 cm, so as to prevent the crayfish from asphyxiation due to hypoxia.

(3) patrolling the pool regularly. Patrol the pool twice a day, find abnormal and take countermeasures in time. During the overwintering period, every 10-15 days, 20 kg per mu of quicklime is sprinkled in the whole pool to disinfect the water body, replenish calcium and prevent diseases.

This is the end of today's introduction to the crayfish about how to spend the winter. I hope this article will be helpful to you.
