Control methods of common diseases of Loach

The common diseases in the process of Misgurnus anguillicaudatus culture are: red skin disease, curved bone disease, water mildew disease, parasitic disease, bubble disease and enemy organisms and so on. The characteristics and control methods of these diseases are introduced below.

Red skin disease

The disease is caused by damage to the Loach body in the process of fishing and transportation, or bacterial invasion caused by the deterioration of water quality. The fin, abdominal skin and anus of the diseased Misgurnus anguillicaudatus are congested and fester, especially the caudal fin and pectoral fin.

Prevention and treatment of red skin disease of Loach

It was found that the disease could dissolve 20 grams of furanes aqueous solution according to 1 cubic meter of water, and wash the sick Loach for 15 to 20 minutes; it could also be fed with furanes, which accounted for 0.04% of the body weight of Loach in the whole pond, for 3 days, and the effect was significant.

Curved bone disease

The dorsal bone of Misgurnus anguillicaudatus is bent due to abnormal water temperature and vitamin deficiency during hatching.

Prevention and treatment of Misgurnus anguillicaudatus curved bone disease

Keep the temperature right when hatching, prevent the water temperature from changing sharply, and feed mixed feed.

Water mildew

Due to the low water temperature or the injury of Loach in winter, it is easy to be infected with water mildew after the beginning of spring. The sick Loach is covered with white cotton-like water mold.

Control methods of water mildew of Loach

When the disease is found, water mildew can be cured by washing the Loach with 2%-5% salt water for 5 ~ 10 minutes, or with 10 mg / L formalin solution for 15 ~ 30 minutes.

Parasitic disease

Loach seedlings often have rotifers, third-generation parasites and other parasites. Loach seedlings attacked by parasites often float on the water surface, anxious, or spin on the water surface.

Control methods of parasitic diseases of Loach

The sick fish pond can be sprinkled with a mixture made of 0.5 grams of copper sulfate and 0.2 grams of ferrous sulfate according to 1 cubic meter of water.

Bubble disease

Loach seedling stage, due to the excessive content of oxygen or other gases in the water, it is easy to lead to bubble disease. The sick Loach is inflated in its intestines, its abdomen is bulging and floats on the surface of the water.

Prevention and treatment of Bubble Disease of Loach

In the severe pool, the whole pool can be sprinkled with salt water with a concentration of 1 g / liter, or add fresh water. Usually bait should pay attention to appropriate amount, diversification, and strengthen water quality management, can prevent the occurrence of this disease.

Enemy pest

The main enemies of Loach are frogs, aquatic insects, birds and fierce carnivorous fish.

Prevention and control methods of enemy pests

1. Remove weeds by the pool, keep the breeding environment hygienic, strictly prevent frogs from invading, catch frogs and remove frog eggs in time.

2. The water inlet should be blocked with a sieve net to prevent wild miscellaneous fish from entering the pond.

3. Find birds and drive them away in time.
