Mycosis of swim bladder
The pathogens are half-known subphylum, coelospora, grass stem mildew. The mycelium is branched and diaphragm, about 50 μ m ~ 100 μ m long and 2 μ m ~ 3 μ m wide. The new culture on Sabru Agar was light yellow, gradually changed to light pink with aging, and finally black, resulting in conidia, which produced colorless and transparent conidia.
The symptoms of diseased fish are mostly fry and fingerling, swimming imbalance, anal swelling, fin bleeding and skin damage. In the early stage, only the swim bladder was damaged, and some white areas 1 mm ~ 2 mm in size appeared at the front of the swim bladder. The initial infection site was in the vicinity of the bladder tube, and then the cavity was filled with mycelium, and the wall of the bladder proliferated, and soon the wall of the bladder was destroyed, thus infecting the nearby internal organs. There was acute inflammatory reaction or chronic granuloma, and the injured organs had congestion spots and necrotic areas.

Now I introduce several very practical disinfection methods.
