The winter management of apple snail is very important, affecting the breeding benefit of apple snail, so how to manage apple snail in winter? Let's introduce it below.

8-10 Mid-month to prepare for hibernation, early appetite gradually Sheng, store nutrients, ready for hibernation. Before entering hibernation, its food intake is reduced, and it is advisable to feed it twice a week. When the water temperature drops to about 10C, the snails begin to hibernate. The winter management methods of golden apple snails are as follows:

(1)Dry overwintering: When the water temperature drops to about 12C, the snail is taken out, washed with clean water and placed indoors to dry.

In the drying process, the snail discharges feces and no longer comes out without water. 3-5 After days, the shell and dead snails are removed and then packed into cartons. Packing should put a layer of snail, pad a layer of paper scraps or stubble, and then tied up, placed in 6-15 degrees ventilated dry place winter. Avoid freezing injury during winter. When the water temperature rises above 15C in the coming year, the snails are put back into the water and they begin to move and feed.

(2)Overwintering with film: When the water temperature drops below 12 degrees in winter, the pool surface should be covered with plastic film.

Sunny sunny days, shallow pool water (10-15 cm), in order to increase the temperature, deepen the water level at night more than 50 cm, in order to facilitate heat preservation. Water is usually changed once every 3-4 days to maintain proper oxygen content. At the same time to prevent rats, cats and other natural enemies harm apple snails. Organic fertilizer is applied one week before waking up after hibernation. If the water temperature is more than 15℃ in winter, feed should be properly fed. If the water temperature is often above 20C, water quality management and bait feeding management should be strengthened in winter management.
