The long kiss, also known as the Jiang Tuan, is a valuable economic fish in China. After several years of pond high-yield aquaculture, the output basically reached 400-500 kg/mu. The farming techniques are summarized below. First, pond conditions require fresh water, high dissolved oxygen, and a pH of 7 to 8.2. Therefore, the pond should be located near a water source where irrigation is convenient and the environment is quiet. The pond area is generally 1000-3000 square meters, water depth is 1.5-2 meters, rectangular, east-west direction, the pool wall is hardened with masonry or cement, the bottom sludge is no more than 10 centimeters, and each pond is equipped with a 3-kilowatt impeller aerator. One. Second, the fingerlings of the fish are selected and cultivated by the artificial domestication of a winter-aged fingerlings, and the physique is robust and the specifications are neat. In general, put 70 to 100 grams of 800 to 1200 fish per acre, mix 150 to 200 grams of white tortoise 250 to 300 fish, 75 to 100 fish, add another 5 fish or squid to control the wild fish in the pool. Put squid, grass carp, tilapia, and other forcing fish. Fish stocking is generally good in early March. Ten days before the fish species were stocked, 100 to 150 kg of lime were used to flood the whole pond and 7 days later, the water was discharged to the required water level. Before stocking, fingerlings were soaked in 15 to 20 mg/kg potassium manganate solution or 3% to 5% salt water for 15 minutes to kill pathogens and enemy pests. Third, after feeding the feed through the seedling stage after the transfer of domestication, the long kiss to the main feed, the crude protein content to reach 40% to 45%, the main raw material for the import of fish meal, dried fish, bean cake, peanut cake, wheat Bran, yeast powder, mineral salt, vitamins, etc., made of hard pellet feed, particle size of 3 mm, 4 mm, 5 mm. The grain size of the feed was 3 mm at the beginning and was later changed to 4 mm and 5 mm with the weight gain of the fish. Feeding should be fixed, timed, and quantified, and a feed station should be built on the side of the pond. After the fish species are stocked, they are domesticated and firstly trained with sound at the feed table to make the pool fish form conditioned reflexes. Then the fish is slowly fed by hand and fed twice a day at 8 am and 8 pm in the morning and in the morning. The proportion of feeding in the afternoon is 4:6, and each operation should be careful, until the fish are fully fed, the daily feed is generally 1.5% to 3%. Fourth, water quality regulation Long kiss? Love water quality fresh, high dissolved oxygen pool water, usually should strengthen water quality management, adhere to regular refilling of new water, timely start aerator, rational use of biological agents to regulate water quality. June-September is the long-season growth season. Flush once every other day, once a month for sewage and water changes, and change the water volume to 1/4 of the pool water. As much oxygen as possible to increase equipment, timely start aerator, boot time for sunny noon open, cloudy early morning, continuous rainy open midnight, early evening not open, floating head early to open, growing season every day open, running time is noon short, midnight long , Cool, short, hot, long load, long time, small load, short time. Apply photosynthetic bacteria regularly at a dosage of 10-20 g/m3. Sprinkle lime water regularly, usually splashing once every two weeks or so during aquaculture. The dosage per acre is 5 to 10 kg. Always keep the water dissolved oxygen in the pool not lower than 5 mg/L, pH 7.2-8.2, and the water transparency is 30-40 cm, but according to season and pond water quality, the water should not be too lean and should be medium It is better to have a lighter fatness. If the water is abundant and the temperature is suitable, micro-flowing water may be used to supplement the method of flushing water regularly. 5. Routine management The patrol pond should be diligent, stick to the daily ponds in the morning, mid-morning, and afternoon, clear the residual feeding, dirt, and cleaning materials, observe whether there are floating heads in the pond fish, and increase the number of night patrols during the hot season and sudden changes in the weather. Or arrange night shift management. Eat food as early as possible, and feed and domesticate the fish on the second day after stocking. Combine with the patrol pond and look at the weather every day, see the water color, and watch the fish eat and eat. Every 15 days random sampling of fish, check the fish's food intake, fat and thin, and through weighing, counting, calculate the growth rate of fish, the total pond fish and feed titer to determine the amount of feeding the next stage. 6. Disease prevention and treatment Every half month, the whole pool is splashed with quicklime once, dosage is about 10kg/mu, feedstuff is added with 1.5% allicin for a long time, and then bait is fed with fish speed again every month for 3 consecutive days to prevent enteritis. Each month, the king will use chlorine to kill the king and copper sulphate alternately sprinkling the entire pool, use the concentration of chlorine to kill the king 0.2 ~ 0.3 g / cubic meter, copper sulfate 0.3 ~ 0.5 g / cubic meter. In feeding and management, observe fish feeding conditions at any time, and find out that abnormal reactions or diseased fish should be treated as soon as possible.
