Giant salamanders hibernate in winter.

The giant salamander is a rare wild animal special to China, commonly known as "salam fish". Due to its slow metabolism, it has a strong ability to withstand hunger when food is scarce. Its activity gradually decreases from September to October. In winter, it hibernates deep in caves or under large rocks in deep water, usually for up to 6 months until it begins to become active in March of the following year.

It’s just that it doesn’t sleep deeply during hibernation, and will still crawl when frightened. Generally, when raising giant salamanders, it must be fed with sufficient food before hibernation, so that the giant salamanders can reserve enough energy for hibernation. In addition, during hibernation, giant salamanders must Keep quiet or the giant salamander will be easily frightened.

Giant salamanders spend the winter

Cold winters often cause overwintering fish species to suffer freezing damage. The following five methods can be adopted to avoid cold and warm up:

1. Avoid obstacles and avoid harm. Use wooden and bamboo sticks to drive piles on the north side of the fish pond, surround it with woven bags or straw, and set up artificial barriers to resist the north wind.

2. Apply manure to increase temperature. Approximately 500 kilograms of livestock and poultry manure should be applied to each mu of water surface. Fertilizer is used to ferment, decompose, and release heat to increase water temperature.

3. Smoke for warmth. Whenever the north wind blows during the day, it is a precursor to frost at night. Wet straw and firewood can be piled on the bank of the fish pond to light a fire and smoke to create a warm atmosphere and reduce the degree of frost.

4. Put in aquatic plants. In winter, a certain amount of aquatic plants are put into the fish pond so that the fish can keep warm and ward off the cold in the grass.

5. Inject water to increase temperature. In the afternoon on a sunny day when the temperature is high, the shallow water heated by the sun is poured into the fish pond.
