Squid is a member of the order Carassius, common carp subfamily, and widely salty fish. China's coastal areas are distributed and rich in resources. Carp has the characteristics of rapid growth, wide adaptability, strong disease resistance, and delicious meat. Deep love people welcome. The cultivation techniques are as follows: 1. Construction of the pond: Choose a place where the water source is rich and the water is fresh and pollution-free. Each pond is 5-8 acres, with a rectangular shape, and the north-south direction is better. The bottom of the pool is required to be flat, sandy mud bottom, and the pool shore is firm with a depth of 2 meters. The bottom of the pool should be buried into the drainage and drainage pipes. At the same time equipped with 1 to 2 sets of 1.5 kilowatts of oxygen aerators, farms have to generate standby units. When dredging, the dredging and disinfection of the ponds should be well done. They can be disinfected with 50 kg of quick lime or 5 to 10 kg of bleaching dry pool per acre in the week before release. Before laying the seedlings, basic feeds for cultivating the pool water should be applied to make the pool water green or brownish. Second, seed cultivation: Seedlings (1.5 to 2 cm in length) to be harvested from the sea area should be desalinated to a salinity of 4 to 7 hours before being put into the holding pool (1 degree salinity), and the stocking species should be natural in the northern area. Seedlings are the best. Because the physicochemical factors of different seedlings grow fast and the individuals are large, the breeding cycle can be shortened and the economic benefits can be increased. The stocking density in the holding pool is controlled at 1 to 20,000 acre, and the pond is often flushed with oxygen. On the second day of the next pond, fresh live feeds such as zooplankton and red worms were started. Slowly the fish slurry, buoyant particles, and bait were mixed and fed with fresh live food, gradually acclimated to feed the crushed fish larvae and buoyant pellet feed. . The daily feeding amount was 15% of the fish's body weight and was fed 3 times. During the holding period, it is disinfected once a week with 0.3ppm strong chlorine or 15ppm formalin. Within 3 days before the start of feeding, 0.5g of trimethoprim, 3g of oxytetracycline, and vitamins are taken for every 50kg of fish. C1 grams, fed once a day, even for 3 days. After more than 20 days of feeding, the fish grows to 4-6 cm in size and can be reared in large ponds. Third, feeding and management: After the seedlings are sifted, they are bred by the size of the pool. The stocking density is generally 2500-3500 tails/mu. Water depth is 1.5 meters or more. To maintain suitable water in the pool water, the transparency should be 30 cm, and the water color should be greenish. Feeding twice a day, the main feed is crushed fish gizzards and buoyant pellet feeds. Vitamins B and C are added to the feed. Daily feed is 6% of the fish's weight. Every month, we also need to feed soil mold, erythromycin, vitamins and drugs for 2 times, each time for 3 days. At the same time, the whole pool of ponds was regularly disinfected with 0.4 ppm strong chlorine or 20 ppm formalin. Drug control should be used with caution such as trichlorfon and mercuric nitrate. Do a good job of patrol pond management every day, turn on oxygen at night or when the weather is hot and low, and find that the pool water should be drained in time to keep the pool water fresh. Fourth, disease prevention and control: carp strong disease resistance, not easy to get sick under natural conditions. However, due to the great changes in the living environment and space of artificial high-density culture, it is very easy to cause diseases. Disease prevention must be strengthened. Drugs should be regularly disinfected on the culture ponds and food tables, and diseases should be treated as soon as possible.
