The young and the young
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 young fish and the dip pool once a week with 40 mg/elevated potassium manganate solution. It is best to use the antibacterial and digestion-promoting Chinese herbal medicines to soak the quail once a week to improve the disease resistance and digestion and absorption capacity of the larvae. 3. When the larvae surface is large, a small amount (about the entire surface) can be placed. 1/3) Water Lilies can not only purify the water, but also serve as a hideout for children. 4. To maintain the earth's moisture, it is best to keep the air free from turbidity. 5. Feed the feed and replace the water. All operations such as disinfecting the carcass are required to ensure the quiet environment around the pond; 6. After a winter feeding, when the outdoor temperature reaches 20°C or above and the water temperature reaches 15°C or higher, the temperature of the greenhouse may be appropriately lowered until the outside temperature is reached. When approaching, you can enter the breeding stage.
