The reason why fish disease cannot be cured for a long time

In the hot season, there is a high incidence of fish disease. after the occurrence of fish disease, some aquaculture farmers often use medicine on their own, but they are always unable to cure it, and some are even getting worse and worse. After in-depth visits, investigations and studies, it is found that the common reasons are as follows:

1. The diagnosis is not accurate, which leads to the wrong medicine. Lack of clear understanding of pathogens and prescribing drugs according to experience and folk prescription is one of the common reasons leading to prolonged treatment of fish disease. Therefore, in the treatment of fish disease, we should first strive to diagnose and treat accurately.

two。 The drug doesn't work. All kinds of drugs have shelf life, the use of expired metamorphic drugs, not only can not achieve the purpose of treatment, but also harm farmed fish. Therefore, before using the drug, you should know whether the drug is within the shelf life, and do not use expired drugs.

3. The dosage and duration of medication are insufficient. Insufficient use of drugs, or shorten the duration of treatment, drooping and immortal pathogens, a little gasp, and will intensify the comeback, resulting in the extension of the disease, repeated attacks. Therefore, in order to ensure the curative effect, the drug must be used in accordance with the dosage and administration method specified in the instructions.

4. Pathogens develop drug resistance. As a result of the use of the same drug, the pathogen became resistant to the drug. For this reason, other drugs that are sensitive to pathogens must be re-selected for treatment in order to obtain the ideal therapeutic effect.
