In order to solve the problem of catching and catching of muddy fields, in 2000, we conducted a cage culture loach test in a field in the Changjiang Special Fisheries Research Institute of Yong’an County, and put in 81.46 kg of loach seedlings in a 122-meter 2 cage. During the day's breeding, a total of 567.3 kg of loach was captured, achieving better economic benefits. The introduction is as follows. 1. The experimental rice paddy area has an area of ​​230m2, sufficient water supply, convenient drainage and irrigation, and 50cm in width and 60cm in width. 2. The cage nets are 4m 5m, 3m 4m, 3m 3m, the height of the cage is 1m, the distance between the cage and the fence is more than 50cm, and the cage is filled with water 40cm. Spread 20 cm thick manure rice, field mud, etc., hang a plastic bowl with a diameter of 30 cm and a depth of 8 cm as a bait station, cover the box to prevent the damage of the kingfisher. 3. The seedlings of the stocking loach seedlings are purchased from the market and require a strong and shiny constitution and neat specifications. On July 7, 2000, the seedlings were released and a total of 81.46 kg of muddy seedlings with a tail weight of 6-8 grams were put into use. 4. After feeding and managing the seedlings, they were fed and domesticated on the 2nd day. The feed was hoped for by Fuzhou Hope Feed Co., Ltd. The branded feed has a protein content of 33%-8%. It is advisable to eat within 2 hours after feeding. Loach is omnivorous fish, plankton, benthic organisms, organic debris, etc. is its excellent natural food, you can also feed some egg yolk, fish meal, bran, rice bran, bean dregs, bran, etc., usually appropriate fermentation Organic fertilizer, and pay attention to adding new water, adjust water quality, keep the water quality fat, live, tender and cool. Particular attention should be paid to avoiding escaping. In seasons where there is more rain in spring and summer, pay attention to drainage and cleaning. During the cultivation period, fin fin disease was found, which was mainly caused by an infection of a bacillus. The back muscles of the diseased loach were inflamed and rot, swollen from head to tail, erythema, and 1 g/m3 of white powder could be effectively treated. 5. Test results On November 7, 2000, a total of 567.3 kg of loach was harvested, the largest individual was 35 grams, the average tail weight was 29 grams, the total expenditure was 4,150.68 yuan, the total income was 9076.8 yuan, and the net income was 5,061.12 yuan.

The status of management of nosocomial infections in gastroscopes:At present,the gastroscope,biopsy forceps cleaning,disinfection,and sterilization have not received enough attention.China is a high-risk area of viral hepatitis.Among all the country,the infection rate of hepatitis B virus is 42.4 % to 80.7 %;the detection rate of human HBsAg is 10 %,and the annual incidence rate is 230/100,000.At the same time,the number of HIV infections is rapidly increasing. Some hospital patients have not detected any infectious diseases before gastroscopy.AIDS patients often conceal their medical history when they visit the clinic.During the process of gastroscopy,they can easily cause nasal mucosa and upper digestive diseases.Oral mucosal bleeding,or because of poor blood coagulation mechanisms in patients with liver disease, leading to gastric mucosal bleeding,blood containing hepatitis B and other viruses will pollute the pipeline, such as gastroscopy,biopsy forceps sterilization is not complete,will cause pathogenic microorganisms The survival and reproduction of other patients,the pathogenic microorganisms can invade the human body through the damaged mucosa,causing iatrogenic infection,especially hepatitis B virus and HIV.
