Prevention and treatment of diseases in bamboo shell fish

Bamboo shoot shell fish is also a common fish, and it also has a certain culture area in our country. The prospect of culturing bamboo shoot shell fish is very good, but there are often some problems in culture, such as various diseases are the most common. The disease will harm the growth of bamboo shoot shell fish in varying degrees and seriously affect the efficiency of culture. So the editor today brings you tips for disease prevention and treatment of cultured bamboo shoot shell fish. Let's take a look at it.

1. Water quality management

When culturing bamboo shoot shell fish in ponds and other culture environments, the main reason for the high incidence is due to poor water quality. The requirement of water quality of bamboo shoot shell fish is relatively high, and good water quality management is an important measure to improve the survival rate of bamboo shoot shell fish. When preparing the pond, first of all, it is necessary to remove the silt at the bottom, reduce the content of various gases, control the PH value at about 7.5, and disinfect the pond with chemicals such as strong chlorine. After irrigation, copper sulfate is sprinkled in the pond to destroy algae, inhibit the growth of cyanobacteria bloom, prevent excessive release of toxins, resulting in the death of bamboo shoot shell fish. Finally, it is necessary to maintain the transparency of about 50 cm, and then prepare aerators and other equipment to change water regularly to ensure water quality.

2. Parasitic diseases

Disease characteristics

When raising bamboo shoot shell fish, the most common disease is parasitic disease, taking the anchor head flea as an example. The anchor head flea will be parasitic under the fins and gills, and the diseased fish can be seen clearly. There are no obvious symptoms in the early stages of the disease, but parasites bite the fish epidermis, leading to a variety of surface diseases. In the middle and later stage, the disease department appeared swelling, suppuration and other phenomena, which finally led to the death of diseased fish. If it is not dealt with in time or killed improperly, it will not lead to death immediately, but the death lasts for a long time and has a great impact on the efficiency of breeding.

How to prevent and cure

The drug resistance of bamboo shoot shell fish is very strong, and it will not cause harm to bamboo shoot shell fish when using drugs that are twice as high as the standard. Therefore, all kinds of insecticides can be used to control parasites. However, because the bamboo shoot shell fish is a kind of bottom fish, we should control the dosage of pesticides according to the water quality, and it is best to keep the pond water running. After the first use, use it again at an interval of about a week. To maintain periodicity, long-term insecticidal, in order to achieve obvious insecticidal effect.

3. Body surface diseases

The scales of bamboo shoot shell fish exist in the shape of inverted thorns. during capture and transportation, bamboo shoot shell fish are very easy to rub against each other, resulting in surface injury and infection leading to disease. This is also the main reason for the low survival rate of bamboo shoot shell fish. In the transfer of breeding sites and the release of large-scale fish species, the wounds of injured fish should be disinfected first. Soak in potassium permanganate and other solutions for about an hour, and then temporarily keep it in disinfectant for about 40 hours. Change the water once a day to ensure an adequate amount of dissolved oxygen and release seeds only after the epidermis wound heals gradually.

The above techniques for disease prevention and control of bamboo shoot shell fish are briefly introduced. After the breeding enters the summer, because the hot and humid environment is very easy to breed germs. Therefore, we also need to regularly use raw lime powder to disinfect the whole pond to create a good aseptic living environment for bamboo shoot shell fish. That's all for today's introduction.
