1. Overwintering of young cubs For juveniles hatched during the summer (June-August), they can store more energy before wintering and weigh around 10 grams. For such cubs, they can naturally hibernate.
The overwintering pool of young cubs should choose a place where there is plenty of sunshine, a quiet environment and sheltered from the wind. There is less silt in the pool and the area is suitable for 100 square meters to 300 square meters. Before winter, choose sunny days to expose the wintering pond for 3 days to 5 days, then disinfect it with quick lime pond, disinfect with 40 mg/l potassium permanganate solution, and pour suitable amount of organic fertilizer at the pool every 100 square meters. 25 kg to 40 kg, water injection 50 cm. When the water temperature dropped to 15 °C ~ 18 °C when the pups into the wintering pool, about 100 per square meter. After the larvae enter the pool, feed the palatability feeds with a high protein content, and pay attention to adding fresh water to keep the water fresh.
Second, juvenile wintering For late summer late autumn (late September to early October) hatched juvenile, its stored material in the body can not meet the energy consumption during the long hibernation. For these larvae, the method of overwintering in the greenhouse should be used to promote the pupa to maintain normal appetite and growth during the winter, so that feeding for about 18 months, wolfberry can reach the product specifications.
Specific management measures:
1. Change the water before each feeding. Change the dirty water 1 hour to 2 hours after feeding.
2. Disinfect the larvae and Dianchi Lake with a solution of 40 mg/kg potassium manganate once a week. The best condition for weekly use of antibacterial and digestion-promoting Chinese herbal medicine is to soak the quail once, which can improve the disease resistance and digestion of the larvae. Absorptive capacity;
3. When the water in the rearing pond is large, a small amount (about 1/3 of the entire surface of the water) can be placed in the pond, which can not only purify the water but also serve as a hiding place for the young fishes.
4. To maintain the greenhouse, to keep the air from becoming dirty, it is best to exhaust it once a day;
5. All operations such as feeding feeds, changing pool water, and disinfecting carcasses require that the surrounding environment of Dianchi Lake be kept quiet;
6. After a winter feeding, when the outdoor temperature reaches 20°C or more and the water temperature reaches 15°C or more, the temperature of the greenhouse may be appropriately lowered until it is close to the outside temperature, and it may enter the breeding stage.
