Urumqi Hongyanchi Reservoir is located5km away from the southern suburbs urea of Urumqi, is mainly based on taking an irrigation, flood control, aquaculture, tourism, urban and industrial water supply, and one of the main fishry bases of urumqi urea. The main fish species of farmed Tilapia sp.,Chub sp., freshwater orbfish, carp sp., Crucian carp sp., Grass carp, pesudorasbora parva et al.Tilapia is increasingly becoming important in the aquatic industry.With the rapid development of intensive fish farming industry, incidence of various types of fish diseases and continuous improvement of dangers has become an important factor restricting the development of the fish farming industry. in July2010to March2011, designed for the Department of thecomposition of the fish parasites and tilapia "ascites" disease research, especially tilapia healthy culture of scientific methods of disease prevention and treatment. The main conclusions are:(1) Resulted in the detection of parasites8kinds:Trichodina sp., Dactylogyrus sp., Gyrodactylus sp., Diplostomum sp., Digeneans sp., nematodes sp., Ergasilus sp., Piscicola geometra. Belonging to the8genera,7families,5orders,5classes,4phyla.(2) Check the ascites disease pathogen, determined by colony morphology and bacterial physiological and biochemical results show that the pathogen Aeromonas hydrophila. Based on the regression test infection pathogenic bacteria, the results prove that the strains of Aeromonas hydrophila.(3) Susceptibility testing showed that the ascites disease pathogens to Ciprofloxacin, Norfloxacin, Gentamicin, Enrofloxacin is highly sensitive, not sensitive to penicillin and erythromycin.
