Carp is tender and delicious, rich in essential amino acids. It is not only a food on the table, but also a traditional medicinal health food. At the same time, carp is also well-cultivated with strong adaptability, miscellaneous food and less disease. The main cultured carp is an efficient breeding mode created in recent years. After several years of practical exploration, it is necessary to pay attention to the following technical points in the breeding process: I. Pond conditions The squid has the habit of hi rushing into the mud and jumping back into the mud and jumping back and forth. The pond area where the main carp is raised should not be too large, generally about 2 mu. It should be no more than 4 mu. It requires that the pond bottom is hard, and the sludge thickness should be within 10 cm. If it is more than 10 cm, it must be dredged to facilitate the carp. For fishing (catching), the pool is solid and does not leak water. Inlet and outlet must be installed with a solid and reliable barrage, which should be 50 cm above the highest water level of the pond. Second, species selection At present, there are many varieties of eel sold on the market, and it is inevitable that there will be a variety of eels. It has been proved that the heterotrophic silver crucian carp and the high-profile crucian carp (abbreviated as the high back carp) are suitable for main breeding, and the growth speed is 2 times and 3 times faster than that of the common carp. The difference between allogynogenetic crucian carp and tall-backed carp is similar to that of common carp. The difference between allogynogenetic silver carp and common carp is: the sideline scales of carassius auratus are 31 to 32 and the common caries are 28 to 29; The number of backline scales is the same, but the height of the back is short, the back is tall, and the abdomen is rounded. Third, the stocking density From the perspective of aquaculture economic efficiency, the stocking amount exceeds 2,000 tails/mu. Although higher yields can be obtained, small-sized commercial fish are produced, the selling price is low, and the efficiency is not satisfactory. The stocking amount is less than 1,000 tails/mu, although individual fish Larger, but the total output is not high, and sales revenue is low. 1400 fingerlings with 30 grams of body weight or 1200 fingerlings with 50 grams of weight per acre are stocked with appropriate amounts of oysters, clams, and summer grass and grass fish. The total number of fish used is not more than 600 fishes. The fish can produce more than 500 kg of squid and 200 fish. About kilograms, the effect is ideal. IV. Water Quality Management The calcium and phosphorus content of the carp is more than two times that of other fish, and therefore it is required that the water be rich in calcium and phosphorus to meet the physiological needs of the carp. It is required to apply a quicklime solution for about 20 days. The dosage per acre is 60 kg each time. Apply calcium superphosphate once every 15 days and use 15-20 kg per acre. Lime calcined for 3 to 5 days before application of calcium phosphate can prevent the alkaline body from excessively reducing the effect of phosphate fertilizer.
