The fry in the primary pond is like the baby in the shackles. It takes care of everyone at all times. The fry grows in the water, and it is more necessary to double your heart and do the following things. Timely fertilization: fry cultivation is mainly based on soy milk feeding, supplemented by fertilization. Soymilk spilled more than a few times, more evenly spilled, to make a daily bait to "three times two full pond" (that is, 3 times a day, 3 times, of which 2 times the whole pond spilled, 1 time around the fish pond splash). Soymilk should be freshly ground and must not be put on hold for too long. Every day, 3kg to 4kg of soybeans per acre are needed. After 5 days, in addition to the pulp, additional bean dregs and bean cake paste are required. When the water in the fish pond is light and the natural food is not enough, it is timely to top-dress. General fish fry 5 days into the pool, top dressing every 2 days to 4 days, to ensure that the fish pond has a certain amount of natural food organisms feeding fish. Regular patrol pond: The number of patrol ponds should be grounded. Every time, we must carefully observe the water quality to determine the amount of bait and the amount of fertilizer applied. Observe the activity and growth of the fish and find that the disease is treated and cleared in time. Prevention of Fish Diseases: Lime water is splashed once every 5 days to 7 days during the cultivation period to clarify the water quality and prevent fish diseases. When the racehorse disease is onset, it is possible to cut off the fry mad swimming route and stop the water injection, and increase the amount of feeding and fertilizer appropriately. When whitehead white beetle disease and white skin disease occur, bleaching powder or strong chlorine fines is splashed and disinfected with pool water for 2 days, and the pool is divided in time to reduce the density in the pool. Timely pooling: fry is cultivated from 20 days to 25 days. When it grows to more than 3 cm, it should be divided into pools in time to reduce the density in the pool to promote the growth of summer flowers and improve the specification of summer flowers out of the pool. Before the summer flower goes out of the pool, it takes 2 days to 3 days to pull the net to exercise. To stop eating for 1 day before pulling the net, the operation should be light and the speed should be slow.
