How do lobsters spend the winter?
In the cold winter, pond crayfish begin to live in their caves, waiting for the temperature to warm up in the coming year.

1. Regulation of water quality
When raising crayfish in winter, the control of water quality is relatively critical. At this time, timely water quality control should be carried out.

This can improve the fertility of the water quality, increase the activity in the water, and bring a more comfortable growing environment for the crayfish. If farming is carried out in the pond, it is necessary to sprinkle rapeseed meal into the pond to increase the nutritional content of the water, and it can also increase the oil to increase the intensity of sunlight and increase the temperature of the water.
two。 Plant aquatic plants
Planting aquatic plants is an essential part of crayfish farming, and aquatic plants are also important for crayfish in winter, because they can increase the oxygen content and activity of the water, and provide a habitat for crayfish. Can also be a certain amount of heat preservation, so as to promote the growth and development of crayfish, but not too many aquatic plants.
3. Feed
Crayfish in the cold when the food intake will decline, which requires us to carry out reasonable feeding. At this time, it is necessary to feed some feed in time, so as to enhance the physique of crayfish to ensure that it can safely survive the winter, generally fed mainly with soybean meal powder.
4. Daily management
When raising crayfish in winter, it is necessary to strengthen inspection and control the water temperature and ph value of the water.
