Summarize The Current Fish Disease, Guangdong Forecast

First, the occurrence of disease in November



According to the forecast point in our province this month, Aquaculture Disease monitoring data analysis, in November the scope of monitoring the types of disease, disease type and morbidity and mortality significantly reduced from last month. Major diseases of fish gill rot, ulcers disease, ciliates disease, fungus diseases, Edward's disease, hemorrhage, red skin disease, bacterial septicemia, bacterial enteritis, ring worm, fish Shi disease The Neden echinococcosis and turtle furunculosis disease, skin fester shot hole, red floor disease, terrapin and the shrimp white spot disease white spot disease, red leg disease, red body disease, diseases such as Torah, disease reduced number of species from the previous month, incidence of Type 4 or more varieties of turtle farming, grass carp, tilapia, perch, carp, eel, mandarin fish, carp, shrimp total of 9 species, 26 species accounted for 34.6% of forecast categories. Grass carp, silver carp, mandarin fish, eel, perch, large yellow croaker, tilapia, carp, factory farming of abalone, a long kiss Catfish, shrimp, shrimp, turtles and other species breeding range of the incidence, morbidity rate and mortality were significantly reduced from last month, but the fungus diseases of freshwater fish, Edward's disease incidence and mortality rate increased slightly in some areas off abalone mortality rate of about 45% of the board.



Two 12-January forecast the occurrence of disease



12-1 month of the year in our province the lowest temperature of the water temperature during the day and night temperature difference is large, aquatic animal disease breeding range forecasting, disease incidence and mortality will be substantially reduced. Farming Fish ulcer disease, enteritis and other bacterial diseases and outdoor shrimp farming such as white spot disease incidence and mortality will be the minimum period of the year, but the fungus diseases of freshwater fish, Ichthyophthiriasis, Edward Greenhouse's disease and the skin fester turtle breeding hole disease, furunculosis disease and shrimp aquaculture greenhouses red body disease, red leg disease, such as white spot disease incidence and mortality rates may rise, sea fish, Benny Teng echinococcosis and abalone off plate disease morbidity and mortality will be similar to the previous month. Mud carp, freshwater pomfret, tilapia, shrimp and other farmed fish and shrimp warm water may cool the freezing cold wave brought a sharp freeze to death. Proposed note tuning in weather, good winter insulation measures, regular monitoring of water quality greenhouses culture, strengthen Xun Tang, pay attention to prevention of fungus diseases, Edward's disease, Ichthyophthiriasis so.



Third, the proposed preventive measures



1, fish prints disease control methods: (1) production of fish during the operation to prevent injury, when the pond had to use 2-5 grams / cubic oxytetracycline water soak 10-30 minutes; (2) All pond spill bleach solution to pond water was 1 g / cubic water body levels, every other day; (3) disease fish concentrated in small concrete ponds, with 20 grams / cubic oxytetracycline medicated bath water (30 days suspended pre-market), 30 minutes once a day, once a 2-3 day cycle; (4) broodstock smear in lesions of 1% potassium permanganate solution, serious fish per kilogram of body weight 15-20 mg of streptomycin sulfate injection .



2, Marine Fishes of the Neden coccidiosis control methods: (1) raceway time by 50 grams / cubic meter of water body of formalin and 0.7 g / cubic meter of water body of copper sulfate, ferrous sulfate (5:2) of fresh water soak 30 minutes, when the disease is once every 2-3 days immersion; (2) in the amount of dietary Vc, immune polysaccharides so as to enhance resistance to disease in fish.
