I. Site selection
After choosing a house with a safe water source and convenient irrigation and drainage, you should build a pond in a place with a leeward sun and close to the discharge port of the digester. The size of the pool can be adapted to local conditions. The general area is 10-20 square meters, and the pool depth is 1.2 meters. Lime or brick knife is used for the pool wall and the surface is cemented. And built a special inlet and outlet, in and out of the barbed wire to prevent it from escaping. A shade shed should be built above the ground, and a trap lamp should be set up.
Second, Qingchi disinfection and stocking seedlings
For every cubic meter of pool water, use 0.22 kg of calcined lime to disinfect and disperse the calcined pulp in the whole pool. Test the PH value of the pool water to 7 or less, or observe the activity of leeches, or put dozens of oysters into the pool water to install. In a good box, if you live in the box for a day and your life is normal, you can stock the seedlings. Artificially propagated or wild seedlings can be used for feeding. The seedlings should be free from injury, disease, and health. Before stocking, put 3%-4% salt solution in bath for 8 minutes, 3-4 centimeters per square meter of oyster species of 80-100 tail is appropriate, stocking specifications can not be too different, so as to avoid eating small phenomenon.
Third, reasonable feeding and timely change of water
Loach is an omnivorous fish. During the rearing process, in addition to the application of biogas residues and biogas slurry to cultivate natural plankton diets, it is also possible to feed suitable snails and oysters, as well as tofu, rice bran, rosin, and tender plants. Stems and other bait. The ratio of daily feeding amount to total weight of loach was: 1% in March, 4% in April-June, 10% in July-August, and 4% in September-October. Feeding should adhere to the four set: the bait station in the pool, put the bait on the bait; timing, every morning and evening feeding each time; positioning, the pool should be fresh, no rot mold; quantitative, 2-3 hours after feeding After eating is appropriate. The biogas residue and biogas slurry will be placed in turn depending on the water quality of the pool. The biogas residue will be put into 250 grams per square meter at a time, and the biogas slurry will be put into 500 grams per square meter at a time, once a week. During the rearing period, trapping insect traps were used as feeding supplements for salmon in the evening. And we must constantly observe the changes in the water quality of the pool. The general water quality should be yellow-green. If muddy water is found out of the water surface, it means that the pool water is over-fertilized and the water is deficient in oxygen. New water should be injected in time and the old water should be drained. Especially in hot or thunderstorms, it is necessary to pay attention to the timely injection of new water and oxygen. Conditions can also be installed oxygen aerator to prevent death.
IV. Preventing and Preventing Predators
Common diseases are skin mildew and rot fin disease. Use a 10-15 μg/ml solution of antibiotics to soak the affected area for 10 minutes, or use a bleaching powder (containing 25-30% of available chlorine) at a concentration of 110-6. Common parasites are trichomonads, tongue beetles and so on. Parasites parasitize the seedlings and cause death. The diseased fish have symptoms such as increased surface mucus, outliers, floating water, and loss of appetite. At this time the diseased fish should be microscopically observed in a timely manner mucus, in the low magnification field of view about 50 worms or tongue beetles, can be used 0.710-6 copper sulfate Quanchiposa. For rats and snakes, we must constantly guard against patrols.
