Control methods of common diseases of turbot fish

Turbot, also known as European flounder, is delicious and nutritious, in addition, it is also rich in collagen and has a good effect on beauty, so it is an ideal health care and beauty food. Its market price is also relatively high, attracting a lot of artificial breeding, but in the cultivation of turbot fish, the disease problem has become increasingly prominent, often leading to huge losses of farmers, the following pro-agricultural network brings common disease prevention and control methods.

1. Red body disease

Red body disease is a viral disease, caused by iridovirus. After the onset of the disease, the fish gills are anemic, the color is dark gray, the fin is congested or bleeding, and in serious cases, the whole fish body bleeds, which is the origin of its name. It is also accompanied by a decline in food intake and poor activity, which basically does not cause death at the initial stage, but when it is serious in the later stage, it will die soon.

Prevention and control methods: usually to strengthen water quality management, regular disinfection, feeding do not choose stale frozen fish, so as not to bring the virus, after the disease is found, the diseased fish should be isolated in time to prevent it from speeding up infection. Antiviral drugs are added to the diet twice a day and can be cured after about a week.

2. Baiji disease

Baiji disease is a common bacterial disease, the pathogen is Vibrio anguillarum, after the invasion of bacteria, the fins begin to turn white, and the edges of the fins begin to curl, and in serious cases, festering occurs. On the other hand, the abdominal area is orange-red, and the seriously infected fish have dim color, no food, weak swimming, and high mortality, which mostly occurs in juvenile fish.

Prevention and control methods: we must strengthen the management of water quality, ensure that the water quality is clean, reduce the culture density, change water frequently, and clean up the dead fry in time. The rotifers and Artemia must be disinfected and then fed, and then sprinkled with high concentration compound glutaraldehyde for 7-8 hours each time for 2-3 days, supplemented with other drugs, which can be cured after about a week.

3. Scabies

The pathogen of scabies is Gram-positive cocci, which is a bacterial infectious disease with great harm. at the initial stage of the disease, the back of the diseased fish appears local redness and swelling, and with the development of the disease, the lesion begins to fester, preferably leading to the formation of yellowish-white ulcerative wound. These ulcerative wounds are usually concentrated in the thick muscles of the back, and in severe cases, the whole fish is pierced, resulting in the death of the fish.

Prevention and control methods: also strengthen management, frequently change water, regular disinfection and sterilization, feed appropriate amount, prevent the emergence of residual bait, the emergence of residual bait must be treated in time, reduce culture density, different growth stages of fish culture in different ponds. When the disease occurs, isolate the diseased fish in time, and then sprinkle the medicine bath with high concentration compound glutaraldehyde, the same 2-3 days, supplemented with other drugs, can be cured within a week.

4. Flagellosis

Flagellosis is a common parasitic disease. the pathogen is the floating fish bean worm, which lurks in the water, waiting for an opportunity to attach to the fish and then reproduce rapidly. In the initial stage, the irregular white spots of bleeding can spread all over the fish body in a day or two. Then fish gills and disease spots have a large amount of mucus and parasites, resulting in a decline in food intake of diseased fish, gradually disappear, slow movement, until death, the disease generally occurs in the period of high temperature, the speed of infection is very fast.

Prevention and control methods: to strengthen water quality management, we must ensure the cleanliness of water quality, remove organic debris and other dirt, and after diseased fish are found, we must first lower the temperature of the water body to restrain the reproduction of parasites. After fishing out the diseased fish and soaking them in fresh water for a period of time, the parasites on the body surface can be killed.

The above are the prevention and control methods of common diseases of turbot brought by the pro-agricultural network. This is the end of the content about the diseases of the turbot. If you want to know more, please pay attention to the pro-agricultural network.
