When winter comes to spring, the temperature of the water gradually rises. At this time, the fish in semi-dormancy begins to swim and the appetite becomes more and more prosperous. Second, at the time of the year, it is spring and early spring, the fishery is quiet, and some fish farmers Often ignore the seasonal solar terms, neglect of timely management, resulting in the production of the year affected. Based on some good practices and experiences of the city and its neighboring fishermen and farmers, the Jinghong Fisheries Technology Promotion Station summarized the technical points of “high yields in fish ponds and three levels in early springâ€: A clear pond clearance, before the stocking of fish must be carefully pond disinfection, kill pathogens to improve the survival rate of fish. The method is to drain fish pond water, dig out excessive and thick silt at the bottom of the pond and expose the bottom of the pond for several days. At the same time, remove the weeds in the pond, repair and reinforce the pond, block the loopholes, level the bottom of the pool, and then 10-15 days before stocking fish clearing pond with drugs, per acre with lime 75kg-100 kg of clear pond. The second is to raise the standards, mainly focusing on early stocking, grasping specifications, quality, catching species, and catching fish. In the third management, after the fish species are stocked, they must adhere to the morning and evening patrols and strengthen management. Pay attention to feeding and feeding. When the water temperature rises to 10°C, the concentrated feed should be calculated based on the weight of the fish. The daily amount can be calculated by feeding 5-8 kg of feed per 100 kg of fish body weight. The feeding principle of feedstuffs is to adhere to the principles of "four look" and "five sets". “Four sees†refers to watching the season, watching the weather, watching the color, and watching the dynamics of the fish. Determine the amount of feeding by looking at the four. "Five set" is the designated person, timing, fixed point, qualitative, quantitative. Healthcare Products
