03 Bloating belly disease
Bloating belly disease is different from hepatic ascites disease, often confused, bloating belly disease is mild aeromonas infection, the disease in the high temperature season, breeding density is too large, poor water quality and frog resistance decline is a multi-incidence period, rapid infection, high death. This disease is different from hepatic ascites, hepatic ascites dissection of the stomach has fluid or blood outflow, and the dissector of the distended belly disease has no fluid, the abdomen is full of gas, the liver becomes purple, the kidney congestion is bright red, some gastrointestinal lining is congested red, there is no food inside, and the internal organs are squeezed to the back to varying degrees.

05 Cataract
Blindness is a common name for cataracts, due to the infection of Acinetobacter calcium acetate, the sick frog has a layer of white film in both eyes, cataract-like, blindness, the appearance of the legs is light green, liver enlargement, purple-black, purple-red, etc., biliary enlargement is pale green, the disease is rapidly transmitted, and the mortality rate is high.
Prevention and treatment: the vaccine can be used to stop the disease by means of injection.

The blood vessels on the inside of the skin are hyperemic, the muscles are earth yellow-green, the blood vessels on the inner side of the abdominal skin are congested, the liver is extremely enlarged and grayish white, earthy yellow, and the gallbladder is light green. Some diseased frogs have hyperemia on the surface of the kidneys, congestion of the bladder, emptiness of the inner surface of the gastrointestinal tract, and hyperemia of superficial blood vessels.
summary
Breeding bullfrog diseases should be mainly prevented, and prevention is greater than cure.
1. Maintain regular disinfection of the breeding pond and change the water regularly (especially novice landscape aquaculture should not have long flowing water, many insect pests and large, and long speed and slowness do more harm than good).
2. Regularly take bile acids in the mixture to protect the liver and gallbladder health of bullfrogs and enhance immunity.
3. Some diseases are caused by adding Eucalyptus essential oil to the feed to inhibit the growth of bacteria.
4. In the process of breeding, it is necessary to avoid diseases caused by artificial operating factors such as excessive density, no size of the pool, mechanical damage, etc., and it is forbidden to use contraband, drugs with large drug residues, etc.
I hope the above sharing can help friends who breed bullfrogs!
