Emphasis on summer adult rearing
Summer is a season of fish growth and it is also a season of fish diseases. Doing a good job of raising and managing summer adult fish is extremely important for improving the quality of breeding and increasing the breeding efficiency. Fertilization In summer, feeding should be repeated every day before and after noon. The bait is mainly composed of cakes, rice bran, wheat bran, and pellet feed, plus some palatable green grass, leaves, and duckweed. If the water quality is not fat, a small amount of fertilization should be used to prevent the pond from over-fatering and cause dead fish. Grass-feeding fish feeding green feed amount, in July, every day, every 100 kg of fish body weight cast 40-50 kg per day, in August increased to 65-80 kg; eat fish feed the amount of fine material, according to every 100 kg body weight per day cast 4 to 5 Kg; The amount of bait feed, such as snails and clams, can be eaten in 7 to 9 hours. The transparency of Tangxia water in summer should be controlled at about 30 cm. If the pond is too thin, more green manure and inorganic fertilizer should be applied. Green manure should be sun dried and mixed with a certain amount of manure before it is used. Heaps in shallow places near the pond, presses stones or mud, and sinks into water. It is turned every 3 to 5 days to allow it to fully decompose, and then Remove the residue, and then add new materials, each applying about 100 kg of green manure. Inorganic fertilizer is applied every 5 to 7 days. Each time, mu is used for 1 kg of urea, or 1.5 kg of ammonium sulfate is added to 1 to 1.5 kg of superphosphate. Before the application, the inorganic fertilizer is dissolved in water (to prevent fish poisoning). Sprinkle water evenly. The frequency and amount of fertilization depends on the weather, water color, and breeder. The sunny days are suitable for more or less, and the rainy days are less or less. When the water color is light yellow or light green, it is applied in multiple ways. When the oil is greenish or reddish brown, little or no application is made. White plover, tilapia, white fleas, and other facilities, grass, herring-based pond less Shi. Adjust water quality One is to inject fresh water every 10 days or so, each time adding 15 to 20 centimeters of water. If the water quality deteriorates, 1/3 to 1/2 of the water should be discharged first, and then fresh water should be injected. The second is about 10 days or so, in the sunny afternoon noon stir the bottom of the pond once, the stirring area is less than half of the pond. The third is the interval of 20 to 30 days, with 15 to 20 kg of lime dissolved in water per acre of water after the spill. Fish disease prevention Observe the pond in the morning and evening every day, and remove the weeds in the pond. Before and after dawn, fish are susceptible to oxygen deficiency floating heads. If the fish has floating heads, aerator or fresh water should be added immediately. If there is no oxygen-increasing equipment, it is possible to sprinkle salt-added yellow mud (10 kg of yellow mud per acre of water surface, add water to a paste, add 10 kg of salt and dilute) to the pond, and the effect is also very good. But be careful not to use bleach, otherwise it will speed up the death of fish suffocation. About 15 days or so, in the pond and the food table with bleach 250 to 300 grams and 125 grams of ferrous sulfate water spilled, can prevent fish bacterial skin disease and gill disease. According to the weight of each 10 kg of fish with 0.5 kg of garlic, chopped and mixed with bait to feed fish, feeding 2 to 3 times a month, each feeding 3 to 5 days, can prevent fish enteritis and other diseases.
