Reasons why fish diseases remain uncured after prolonged treatment
In hot seasons, fish diseases occur frequently. After fish diseases break out, some aquaculture farmers often use medications on their own to treat them, but they always fail to cure the fish, and some cases even get worse the more they are treated. Through in-depth visits and investigations, the following common causes were found:
1. Inaccurate diagnosis, leading to medication that does not match the disease. An unclear understanding of the pathogen and prescribing medication based on experience or folk remedies is one of the common reasons why fish diseases remain uncured after prolonged treatment. Therefore, when treating fish diseases, one should first strive for accurate diagnosis and treatment.
2. Ineffective medication. All kinds of medications have a shelf life. Using expired or deteriorated medication not only fails to achieve the treatment goal, but also harms the farmed fish. Therefore, before using medication, one should check whether it is within its shelf life, and should not use expired or ineffective medication.
3. Insufficient dosage or insufficient duration of medication. If the dosage used is insufficient, or the medication period is shortened, the pathogen that is hanging on but not dead will take a brief breather and come back even more fiercely, causing the condition to persist without healing and to flare up repeatedly. Therefore, to ensure efficacy, medication must be used according to the dosage and administration method specified in the medication instructions.
4. The pathogen develops drug resistance. Because the same medication is used, the pathogen develops resistance to it. For this reason, other medications to which the pathogen is sensitive must be selected anew for treatment in order to achieve the desired therapeutic effect.
