Control of snakehead snakehead disease
(1) pathogenic fish carp.
(2) after the symptomatic diseased fish are parasitized by fish fish, they are extremely restless, swim wildly, jump wildly, increase body surface mucus, and are easy to be complicated with water mildew disease, which do great harm to fish species and can cause a large number of diseased fish to die in serious cases. May to September every year is the peak season of the disease. It is a common disease of snakehead.

Prevention and treatment of lung choking in turtles
Tortoises are divided into dry turtles, aquatic turtles and semi-aquatic turtles. Dry turtles live on land or mountain areas all the year round. Aquatic turtles live in rivers, lakes, ditches, streams and farmland. Semi-aquatic turtles live in the environment where water and land meet all the year round. Under natural conditions, turtles are not easy to choke water or suffocate and die, but under artificial breeding conditions, due to different species or environmental conditions, or artificial improper ways to cause turtle lungs to choke water and die, but sometimes occur in farms. 1. Reasons for choking water 1. Artificial breeding ponds are often small, if the water quality deteriorates

Viral disease: infectious hematopoietic tissue necrosis of fish
[pathogen] the pathogen of infectious hematopoietic tissue necrosis in fish is infectious hematopoietic tissue necrosis virus (IHNV). [symptoms and pathological changes] the diseased fish begin to swim slowly, float downstream, then shake and swim, then float and turn, and often die shortly after intense swimming. The diseased fish have black body color, exophthalmos, dilated abdomen, hyperemia at the base of the fin, and a long, thick white mucus stool is often dragged on the anus. Autopsy showed that there was a large amount of stagnant water in the abdominal cavity, lighter color of liver, spleen and kidney, intestinal bleeding, oral wall and skeletal muscle.
