First, the construction of the pond to choose a rich source of water, fresh water pollution-free place to build pool. 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. At the end, he has to put in the drainage and drainage pipes. At the same time equipped with 1 to 2 1.5KW aerators, farms need to have 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.
2. Breeding of seedlings (1.5 to 2 cm in length) to be harvested from sea areas, desalinated to salinity of 4 to 7 hours and put into temporary holding ponds (1 degree of salinity), stocking species to natural seedlings of northern sea area Best, because of different physicochemical factors, seedlings grow faster, individuals larger, can shorten the breeding cycle, increase economic efficiency. 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 day, fresh feeds such as zooplankton and red worms were started to be fed. The fish slurry, buoyant particles and bait were slowly mixed and fed, and 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. Three days before the start of the feeding, 0.5g of furazolidone, 3 grams of oxytetracycline, and 1 gram of vitamin C are taken per 50kg of fish. Feeding 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 1.5 meters or more, to maintain the appropriate water in the pool, with a transparency of 30 cm, the water was oil green is appropriate. Feeding twice a day, the main feed is chopped fish gizzards and buoyant pellet feeds. Vitamins B and C are added to the feed, and the daily feed is 6% of the fish's body 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 is bad to drain water in time to keep the pool water fresh.
Respiratory Tract Disease Tests
Respiratory Tract Disease Tests are detected the Mycoplasma Pneumoniae
Antibody Test IgM&IgG and Chlamydia Pneumoniae Antibody Test IgM&IgG.
Chlamydia pneumoniae is an important cause of acute respiratory infections, but may also be associated with chronic diseases (24). Because chlamydia pneumoniae was different from other types of chlamydia, a new name was proposed for the bacterium, chlamydia pneumoniae. Although the overall incidence is unknown, there are an estimated 2 to 5 million cases of pneumonia and 500,000 pneumonia-related hospitalizations in the United States each year, according to CDC estimates. While all age groups are at risk, it is most common in school-age children. In addition, according to some researchers, mycoplasma pneumoniae infection may be associated with atherosclerotic vascular disease, as well as Alzheimer's disease, asthma, and reactive arthritis.
Mycoplasma pneumoniae is one of the smallest free-living microorganisms, intermediate in size between bacteria and viruses (6). Its small genome and size make diagnosis difficult. Bacteria are not visible on Gram staining and cannot be grown on standard bacterial media.
