Medicinal bait is the abbreviation of bait made by adding a certain amount of therapeutic drugs into the feed that aquatic animals like to eat in order to treat diseases of aquatic animals. However, with the continuous improvement of aquaculture level, oral drug bait is increasingly recognized by many farmers in the treatment of aquatic animal diseases. Because farmers are careless or abuse oral drugs, the use of oral drugs is unscientific, which has a certain impact on aquatic animals, and the result is counterproductive, and the expected therapeutic effect cannot be achieved. Therefore, the scientific use of drug bait is of great significance for improving the treatment level of aquatic animal diseases. Specifically achieve "ten points for attention":

1. Bait selection of mixed oral drugs: According to the feeding habits of aquatic animals, choose the feed with good quality that aquatic animals like to eat.

2. According to the feeding habits of different aquatic animals, different baits are selected to make different dosage forms of drug baits, so as to facilitate the feeding of aquatic animals.

3. Stop eating for 1-2 days before feeding the drug bait, in order to improve the feeding rate, absorption effect and therapeutic effect.

4. The feeding amount should be reduced by 20-30% during taking medicine, and the feeding times should be reduced every day to promote the absorption and utilization of bait by aquatic animals.

5. During taking the medicine, water quality management should be strengthened, the pool water hygiene should be paid attention to, and disinfectants should be used to enhance the oral effect.

6. It is best to use a bait feeder to feed evenly, and the feeding time should be slower and longer than usual, so that aquatic animals can eat evenly.

7, internal medicine bait must reach enough course of treatment. No matter how good the bait is, if it can't reach the course of treatment, it can't reach the therapeutic effect. Therefore, when treating aquatic animal diseases, the course of treatment is generally 5-7 days. If the situation is serious, it can be extended for 3 days.

8. The drug in the bait must reach a certain concentration, that is, it should be stirred evenly and reach a certain dose. When calculating the dosage of oral drugs, we should not only calculate the weight of all ingested fish, but also add the part of drugs lost in water to ensure adequate dosage and achieve therapeutic effect. Avoid drug resistance of pathogens caused by low-dose drugs.

9. According to the characteristics of oral drugs and the feeding characteristics of aquatic animals, choose appropriate adjuvants to increase the appetite of aquatic animals and reduce the loss caused by the dissolution of drugs in water.

10, the drug sensitivity test of pathogenic microorganisms can be done if conditions permit, so as to better select the best therapeutic drugs, and it is not allowed to mix them with drugs casually. Avoid delaying the disease or causing the toxicity of drugs to aquatic animals and the resistance of pathogens.

In a word, scientific oral bait plays a multiplier role in the prevention and treatment of aquatic animal diseases. But it needs comprehensive consideration and overall planning.
