Management of cultured snails in winter

Prepare for hibernation from August to mid-October, increase appetite in the early stage, accumulate nutrients and prepare for hibernation. Before entering hibernation, the food intake is reduced, and it is appropriate to feed twice a week. When the water temperature drops to about lOC, the snail begins to hibernate. The winter management methods of field snails are as follows: (1) dry overwintering: when the water temperature drops to about 12C, the snail is pulled out, washed with clean water and put indoors to dry.

In the process of drying, the snail discharges feces and does not come out without water. 3After 5 days, the broken shell snails and dead snails were removed and packed into cartons. The box should be packed with a layer of snails, covered with confetti or stubble, then tied up and placed in a ventilated and dry place of 6 Mel and 15 degrees to survive the winter. Do not suffer frost injury during overwintering. When the water temperature rises above 15C in the coming year, put the snail back into the water, and the snail begins to move and feed. (2) Film covering overwintering: when the water temperature drops below 12 degrees in winter, the pool surface is covered with plastic film.

When there is plenty of sunshine on a sunny day, let down the pool water (10m / 15cm) to increase the temperature, and deepen the water level more than 50cm at night to keep warm. Usually change the water once every 4 days in order to maintain the proper oxygen content. At the same time, it is necessary to prevent natural enemies such as rats and cats from harming field snails. When you start to wake up after hibernation, you start to put organic fertilizer a week before. If the water temperature is more than 15 ℃ during the overwintering period, feed should be given properly. If the water temperature is often above 20C, it is necessary to strengthen the water quality management and feeding management of the field snail in winter.
