Loach: Loach is very sensitive to changes in water temperature. When the water temperature drops below 5°C, the loach will enter the silt to winter and the wintering period lasts for 2 to 3 months. During the wintering period, cold insulation work should be done to keep the water depth at 1.5 meters or more and the water temperature should be between 2°C and 8°C. In the paddy field, the loach should be concentrated in the fish ditch before winter, and the straw should be laid on the fish ditch. The loach will then dive into the silt at the bottom of the ditch to overwinter.
Minamata: When the water temperature drops below 10°C, the mink drills into the soil that is loose and loose on the surface of the water to overwinter, and there are also a few wintering in the pool silt. Once the otters enter the overwintering state, people and animals should be prohibited from agitating in the pool so as not to damage the wintering environment of the otters. In order to prevent the temperature from being too low and cause the wintering layer to freeze, a layer of aquatic plants can be covered in the overwintering area to keep warm. When the water surface is frozen, ice should be frequently broken to keep enough dissolved oxygen in the water.
Fertility Pearl: The temperature of the pool water drops below 10°C. The frequency of cardiac pulsation in the river otters is small, and the amount of filtered water, oxygen consumption, and food intake are significantly reduced, and growth is almost stopped. It is not appropriate to apply organic fertilizer to the pool at this time, so as to avoid incomplete decomposition and produce a large number of toxic substances. Surgical lice and cubs should go through the bottom of the pool for winter. If you have just performed surgery, you should not sink into the bottom of the pool. Otherwise, the surgical wound will be contaminated, causing rotting and rotten film. The quail is a cold-resistant animal, but it can also cause death if it is subjected to freezing. Therefore, do not allow the quail to freeze during winter grazing, catching lice and implants.
Jubilee: The pool water should be deepened to about 80 cm. The pool top should be covered with bamboo curtains. The bamboo curtains should be covered with straw insulation of 20 cm to 30 cm thick.
Bullfrog: When the bullfrog goes into hibernation, it is important to keep the wintering pool quiet. During the hibernation period, the bullfrog relies mainly on the skin to breathe, and the oxygen consumption is low. The oxygen in the water can fully meet the wintering demand of the bullfrog. The water temperature in the wintering pool cannot fall below 0°C, and the water depth should not be lower than 1.5 meters.
Huang Wei: There are two kinds of wintering methods for the yellow peony. The first is to bring water through the winter, generally deep water depth of 10 cm to 20 cm, in the water temperature below 6 °C, the yellow cocoon can sneak into the depths of the bottom of the pool cave winter. The ice layer on the water can also play a role in keeping warm. When the temperature is high, the jaundice can breathe out and eat predatory during the day. The second is to drain the water through the winter, that is, drain the pool water before winter and keep the soil in the pool moist. Before the freezing cold weather arrives, cover the surface of the pool with a layer of straw, straw and other things to keep warm and prevent freezing. It should be noted that during the period of hibernation, Astragalus membranaceus is still in a dormant state, but there is still a slight breath, so it is not appropriate to accumulate heavy objects on the Dianchi Lake.
Crab species: Overwintering crab species requires strong physique, uniform specifications, complete limbs, and no disease or injury, and stocks 75 kg to 100 kg per mu. During the winter, maintain a water depth of 1.5 meters or more to maintain a high water temperature. If the water level is too shallow, it must be replenished in time to prevent the crab species from being frostbite and freezing to death. If the water quality is too fat, replace it with new ones in time to prevent death of the crab species due to lack of oxygen. If the weather is sunny and warm during the winter and the water temperature is above 4°C, the crab species will eat a small amount and can feed a small amount of chopped small miscellaneous fish, shrimp, quail meat, etc. to supplement their internal nutrition and prevent the crab species from being consumed due to nutrients in the body. Big and dead.
