How Do Crayfish Overwinter? Detailed Explanation of Winter Breeding Management Methods

In the cold winter, pond crayfish begin their cave-dwelling overwintering life, waiting for the temperature to warm up the following year before emerging from their caves to forage. However, some broodstock and fry will also emerge from their caves. Although crayfish grow rather slowly during this period, strengthening overwintering management for crayfish is still particularly important. So how do crayfish overwinter?

How do crayfish overwinter?

1. Regulating water quality

When breeding crayfish in winter, water quality control is a fairly key factor, and timely water quality regulation is needed at this time. If the breeding site is in a paddy field, the rice straw should be treated in a pollution-free manner, which can effectively enhance the fertility of the water quality, increase the activity in the water, and provide crayfish with a relatively comfortable growing environment. If breeding is carried out in a pond, rapeseed meal should be splashed into the pond to increase the nutrient content in the water, and it can also increase the oil content, thereby increasing the intensity of sunlight so that the water temperature can rise somewhat.

2. Planting aquatic plants

Planting aquatic plants is an indispensable step when breeding crayfish, and in winter aquatic plants are also crucial for crayfish. This is because aquatic plants can increase the oxygen content in the water, enhance the activity level of the water, and also provide crayfish with a place to rest. They can also provide a certain amount of insulation, thereby promoting the growth and development of crayfish, but there should not be too many aquatic plants.

3. Feeding

When it is cold, crayfish eat less, so we need to carry out reasonable feeding work. At this time, some feed should be given promptly, which can strengthen the crayfish's constitution and ensure they can overwinter safely. Generally, the feed given is mainly soybean meal powder.

4. Daily management

When breeding crayfish in winter, inspection work should be strengthened, and water temperature and water pH should be well controlled.
