First, choose a good winter pond. The wintering pond should generally be selected from the villages and towns that are free from plant and mine pollution, and have a convenient drainage source. The water depth is preferably 2 meters or more, the silt thickness is about 30 centimeters, the area is 2-3 acres, and the leeward sun is better. Those who have conditions can grade and grade (winter, adult, young, and young) wintering. The turtle was sterilized by body surface (after immersing in 4% saline for 10 minutes) before falling harvest for winter. Unconditional, the original pond is overwintering.

Second, disinfection of water quality. Before winter, the water quality should be disinfected with standard fishery drugs. After the toxicity (about 7-10 days), turtles can be overwintered. Since the water temperature is high, the overwintering soft-shelled turtle disinfects the water once it is awakened for three days, and once per month it remains disinfected. Disinfection of water should be done by sterilizing surfactants or iodine drugs that are less irritating to soft-shelled turtles, rather than disinfecting them with chlorine-based agents or quicklime that are highly irritating to soft-shelled turtles.

Third, strengthen water quality management and keep the water fresh. The water body requires a transparency of 30 cm, a pH of 7.5-8.5, a total ammonia nitrogen of less than 1.5 mg/l, hydrogen sulfide of less than 0.06 mg/l, and dissolved oxygen of more than 4 mg/l. Next, bamboo plants are used to plant aquatic plants such as water hyacinth (water-lily and narcissus) on the surface of a pond with a bamboo (net) piece of 60-70 square meters per mu. These aquatic plants absorb ammonia nitrogen and carbon dioxide in the water through a developed root system for photosynthesis, release oxygen to meet their own growth needs, and also purify various harmful substances in water (purify oils, aniline, toluidine; purification of phenols; purification Organic matter); Eichhornia crassipes can accumulate many harmful chemical elements (silver, aluminum, cadmium, phosphorus, potassium, nitrogen, iron, sodium, etc.) Well-developed roots and luxuriant stems and leaves are also good places to keep in use. Sun back place. The stems and leaves of aquatic plants such as Eichhornia crassipes can be used as feed for pigs, ducks, chickens, geese and other livestock to achieve a healthy recycling of ecological resources. The third is to put 60 mullet per mu of pond and 20-30 mullet of polyculture. The benefits are: carp filters for phytoplankton (algae), catfish feed on zooplankton, effectively control the overproduction of plankton, and maintain a reasonable and stable water quality. Fourth, when the water temperature is above 20°C for several consecutive days, the weather should be properly poured into 30 cm of fresh water, discharge some of the old water to dilute poisons, increase the amount of dissolved oxygen in the water, and keep the water quality fat, live, tender, and cool.

Fourth, during the wintering of the turtle, it is also necessary to treat the pond sediment so as to reduce the harmful substances in the sediment sludge. Sediment purification during wintering can be achieved by the introduction of zeolite powder or base medicine.

Fifth, the release of beneficial bacteria. Such as photosynthetic bacteria, sulfurized bacteria, nitrifying bacteria. Through biological action to increase dissolved oxygen in water, reduce harmful substances in water and inhibit the growth and reproduction of harmful bacteria.

6. During the wintering season, when the water temperature rises above 20°C, it will awaken halfway. At this time, feed should be fed to supplement the energy consumed by the body. However, if it is fed on the water, the soft-shelled turtle is unresponsive and generally does not feed on it. Therefore, underwater feeding should be adopted. It is best to feed fresh fish. The feeding method is to use wire to pass through the head of the fish and hang it in the water until the turtle eats 2-3 hours before removing the bait to avoid contamination of the water quality environment. Require daily feeding. once. When the water temperature turns cold (below 20°C), the soft-shelled turtle turns into hibernation, so it does not need to be fed.

After the hibernation period, it is transferred to the normal management of spring culture.
