Early stocking of fish by farmers will enable the farmed fish to adapt to a new living environment in advance, eat earlier, grow early, and prolong the growth period of fish. Because the winter temperature and the water temperature are relatively low, the scales of the fish are tight, and it is not easy to injure the fish body during fishing and stocking, which can reduce the incidence and mortality of the fish species. Therefore, for the farmers, the winter is a season in which the species is more suitable for stocking. .
1, fish pond transformation. "Four changes" to the fish pond: Xiaotang changed Datang, shallow pond changed deep pond, dead pond reactivated pond, and low-narrowed pile changed the height and width.
2, clear pond. After the renovation of the pond, use drugs for clear pond disinfection. Clear Pond drugs usually have lime, bleach, tea pots and so on. Lime clear ponds and clear ponds are commonly used in production. There are two kinds of clear ponds and clear ponds. Drainage clear pond is 100-150 kg lime per acre, and it is splashed with water. When the water clear pond is used, the depth of water is usually 250-300 kilograms per gram of lime, and the whole pool is splashed with lime.
3, fertilization. When the disinfectant properties of the clear pond are eliminated, fertilize the natural body of water. Shi Ji Fei Shi per mu, 500 ~ 750 kg of cow dung, or 100 ~ 200 kg of human waste.
4, stocking. The farmers determined the stocking density and stocking species based on their pasting experience, their own farming standards and production conditions.
5. Feeding and management after stocking. In case of cold weather, it is necessary to deepen the antifreeze in the pool water. When the temperature is fine, it is necessary to feed some concentrated feed properly to ensure the food needs of the fish and promote its growth.
