1. Red leg disease, in which young frogs are more common, but adult frogs are rare. The symptoms are leaving the cave alone, stopping eating, and erythema on the inside of the calf and abdomen. The main reasons are high stocking density, water pollution and bacterial infection. The prevention method is to improve the water quality, adjust the density, and treat it with oxytetracycline chloramphenicol aqueous solution, and the effect is good.
2. The skin rotted, and the skin and mouth and nose rotted, mainly because the feed in Shi Wa was single, lacking nutrition and vitamins, or the scratched surface was infected by bacteria. The prevention and control methods are diversification of feed, strengthening nutrition, supplementing vitamin A capsules or cod liver oil, and combining with antibiotic prevention and control.
3. Gastroenteritis occurs in tadpoles, young frogs and adult frogs. The flatulence and abdominal distension in gastrointestinal tract are mainly caused by water pollution and unclean food, which leads to bacterial infection. Chloramphenicol 10 ~ 15 microgram for external use, oral yeast tablets or 2% chloramphenicol in feed for gastrointestinal disinfection and sterilization.
In the process of feeding Shi Wa, it is important to master the amount of feed to ensure that there is enough food in Shi Wa. Clean up the leftovers in time and change the water regularly to make the water quality of the frog pond good. At the same time, some aquatic plants such as false daffodils and water lilies are put in the frog pond to cover the water surface 1/3, so as to increase the hidden places where frogs live.
Disease control should focus on prevention, isolate diseased frogs and treat them in time. 1. Parasitic diseases: Prevention and treatment: Pay attention to water quality and food hygiene, and use 0.5ppm crystal trichlorfon to soak body surface parasites. 2. Red leg disease: This disease, also called septicemia, is the main disease of young frogs and adult frogs. Prevention and treatment: the disease should be mainly prevented, always pay attention to the hygiene of water and food, and minimize mechanical trauma. Quicklime can be scattered throughout the pool to inhibit the spread of bacteria in the water. The diseased frog can be soaked in 3% salt solution or 20% sulfanilamide solution 10 minute. Or use sulfathiazole 3g and 1kg bait to mix and feed. 3. Rotting frog: The disease is also called desquamation and vitamin deficiency syndrome. At the early stage of the disease, the frog's back skin lost its luster, mucus decreased, wettability decreased, and dry white patterns appeared. Visual acuity declines, and in severe cases, white eyes appear, leading to blindness. Prevention and treatment: feed nutrition should be strengthened in the prevention and treatment of this disease. If the food is mainly insects, some vitamins A, B and C should be added to the bait and treated with antibiotics or sulfonamides. 4. Gastrointestinal diseases: Sick frogs began to inhabit indefinitely, crawling around, swimming slowly, and like to drill mud. Later, I lay flat on the shallow water by the pool, not afraid of being disturbed, limping and swollen all over. When I caught it, I bowed my head and my back, stretched my legs and closed my eyes. This disease mostly occurs in April-September, and it is highly contagious. Prevention and control: remove the residual bait on the food table every day, clean the food table and disinfect it regularly. Gentamicin can be sprayed regularly in the whole pool during the onset season, and it can also be made into bait through anti-inflammatory drugs. Meningitis: the sick frog keeps spinning in the water, with its head turned left or right. The mortality rate of diseased frogs is not high, and their food intake is reduced. If the sick frog is not treated in time, the infection will be quick. Prevention and control: regularly disinfect the frog pond with drugs and change the water regularly. Disinfectant drugs can refer to the use of "strong bactericidal disinfectant", and the drug "Burning Disease Ning II" is mixed in the feed, which has obvious therapeutic effect on the disease. Deal with the sick frog in time.
