The scientific name of the oriental star spot is leopard gill perch, which is a high-quality grouper produced in the South China Sea. It is brightly colored, with black pupils in blue eyes and white speckles all over it. It looks like stars in the sky, so it is commonly called "star spot". As for the word "East", it comes from dongsha islands in the east of China. In the past two years, Dongxing's aquaculture benefits are good, and the amount of aquaculture is increasing. The whole cultural disease will be much more than before. Here are some common questions.

1, Astigma orientalis enteritis

Dongstark enteritis is mainly caused by bacterial infections such as streptococcus. Secondly, it is caused by some complications, such as hepatobiliary diseases, and daily feeding is not in place.

Treatment:

Mild: take changdulikang 10g/kg+ Weichangling 10g/kg once a day for 4 days.

Serious: Take Xilinliqing 10g/kg+ Enweikang 10g/kg+ Weichangling 10g/kg once a day for 6 days.

When the death reduction stops, we can feed Gananhao 8g/kg+ Muweikangbao 5g/kg+ Weichangling 10g/kg for three consecutive days to regulate our body.

2. Rot body of East Star Spot

It is mainly caused by Vibrio infection (Vibrio harveyi, Vibrio vulnificus, etc.). ).

External bubble: soak in hydrogen peroxide 100PPM for two hours, and then use chlorine dioxide.

Soak in 8- 10PPM for two hours, adjust according to the state of the fish, and then change the water and soak in 10PPM, respectively, Calliston+strong fluorobenzene or strong fluorobenzene+Xilinliqing.

Oral administration: strong fluorobenzene 8- 10g/kg+ Europa 6g 10- 12g/kg, once a day, for 6 days.

When the death reduction stops, you can adjust your body by feeding Gananhao 10g/kg+ amino-detoxified C5/kg+ vitamin B 10g/kg to reduce the load on your liver.

3, East Star Spot slimming, white stool

The main reason for slimming is microsporidia infection in the intestine.

Prevention is mainly to improve the body's immunity: feeding immune peptide fertilizer, multi-dimensional marine larvae and amino detoxification C.

The whole liver of this fish is also poor, and some diseases such as contraction or necrosis often occur, so it is also very important for the health care of the liver.

4. East Star Point Floating Head

In the process of breeding, aster often floats near the gas head, which can be soaked in hydrogen peroxide and formaldehyde, and can be soaked in Wellcome, Xilinliqing or strong fluorobenzene if necessary.

5. Acute bacterial infection

The fish body surface is intact, with no obvious symptoms, and there is acute death (dumping) on its side, and dozens of deaths will soon occur.

At the scene, strong fluorobenzene+Callistone+Xilinliqing were used for bathing, which could effectively control the loss, and no other fish losses occurred the next day.

6, East Star Spot flatulence

The main disease is nerve necrosis virus infection.

Can be used to reduce the body's exercise and stress, and avoid inducing the occurrence of viruses. Oral administration of strong fluorobenzene+immune peptide fertilizer+Muweikangbao, amino detoxification C can enhance the body's immunity.

7, the main pest starch egg nest edge worm

This kind of insect is very harmful to the cultivation of Asteris orientalis, and the mortality rate will be high if it is not found in time.

Soak the bath with 2-5PPM copper sulfate for 4 hours on the morning of treatment, and then carry out convection. The water after the medicinal bath was washed by convection, and the grouper was sprinkled with electrolytic vitamins. When feeding, you can take 5g/kg envekam orally to avoid secondary infection after pests.
