Control methods of common diseases of puffer fish

The artificial breeding scale and area of puffer fish are getting larger and larger, but at the same time, the invasion of diseases is becoming more and more serious. There are many kinds of diseases of puffer fish, some of which will cause their death and bring serious economic losses to the development of puffer fish. The following editor brings the introduction of several common diseases of puffer fish, the disease brings its prevention and treatment methods, let's take a look.

1. Bubble disease

Puffer fish inhale and expand when in danger and look like a big balloon, but this is not what bubble disease refers to here. The cause of puffer fish bubble disease is that the water is oversaturated with oxygen or other gases. When the disease occurs, there are bubbles on the surface of the puffer fish. These bubbles float on the surface of the water due to buoyancy, so it is difficult to swim into the water. It is best to die because of repeated struggles that lead to physical exhaustion.

Prevention and control methods: strengthen the management of water quality, avoid the production of toxic gases from the deterioration of water quality, improve the pH value and transparency of the water, delay the occurrence of the disease, and sprinkle 5 kg of salt per mu to increase the concentration of water and reduce the content of gas in the water. treat the disease.

2. Enteritis

Enteritis is one of the common diseases in farmed puffer fish, the cause of which is generally related to feed and indigestion. Hard feed may make the intestines and stomach of puffer fish indigestible, and feed accumulates in the intestines and stomach can not be digested, resulting in gastrointestinal inflammation. Overfeeding can also cause enteritis. At the onset of the disease, the diseased fish swim alone, the body surface is black, the abdomen is upward, the appetite is weakened or abolished, the anus is red and swollen, and soon the diseased fish will die. If you dissect the diseased fish, you will find that the intestinal wall is inflamed and full of pus.

Prevention and control methods: the best pond disinfection work, feeding should follow the four principles of timing, quantitative, fixed point, fixed quality, excellent feed can be softened in feeding. The disease can be treated with oxytetracycline and allicin in the feed, or the whole pool can be sprinkled with oxytetracycline hydrochloride.

3. Water mildew

The pathogen of water mildew disease is water mold pathogen. After infection, the body color of puffer fish gradually becomes lighter, and there are hemorrhagic red spots on the body surface. In the later stage of the disease, the diseased fish do not eat, and cotton-like objects appear on the body surface, which will cover the whole fish body in a short time, resulting in death.

Prevention and control methods: strengthen the regulation and control of water quality, do a good job of water disinfection, keep the water quality clear, and avoid body surface injury of puffer fish as far as possible. During the attack, 10% potassium permanganate can be sprinkled in the whole pool, or the diseased fish can be soaked in baking soda or salt water for a period of time.

4. Outbreak

The pathogen of the outbreak is Aeromonas hydrophila. After the disease, the fin on the body surface of the puffer fish begins to become congested, and when it is serious, the body surface is seriously congested. Some will also have symptoms of orbital bleeding, exophthalmos and Gill decay. Dissecting diseased fish will find intestinal wall hyperemia, more mucus, enlarged gallbladder, and black spleen. When the disease is serious, the sick fish will be restless or lie still at the bottom of the water, it is best to die, it has occurred when the water temperature is high, the course of the disease is shorter, and it can die 24 hours after the onset of the disease.

Prevention and control methods: disinfect the whole pond before releasing seedlings, pay attention to the density during stocking, should not be too dense, and keep the feed fresh. When the disease occurs, first disinfect, and then add allicin and vitamins to the crimson of the tearing.

The above are the prevention and control methods of common puffer fish diseases. I hope I can help you. If you want to know more about puffer fish farming, please follow us.
