Measures to improve the efficacy of fish drugs

Due to the use of fish drugs in the water environment, there are many restrictive factors, so it is often difficult to achieve the ideal effect. In order to improve the effect of drug application, we must pay attention to the skills of drug application.

1. The choice of external and internal medication

When the disease occurs in the fish pond, it is necessary to diagnose the disease accurately and quickly, such as red skin, rotten Gill, white skin and other common bacterial diseases, such as red skin, rotten Gill, white skin and other common bacterial diseases, such as red skin, rotten Gill, white skin and so on. If parasitic diseases are found, they should be used both internally and externally, and one water disinfection fungicide should be used externally before using internal medicine.

two。 Add adhesive

Internal medicine is mostly fine powder, if the drug is directly mixed and fed, it is easy to be lost and wasted in the water, affecting the treatment effect and delaying the treatment opportunity. If the adhesive with high quality flour, sweet potato starch, mung bean and broad bean powder as the main raw materials is used, and 0.6%-0.8% medicine is mixed into a ball or granulated feed, the drug effect can be brought into full play.

3. Add food attractant

The sense of smell of fish is very sensitive, such as strong-scented traditional Chinese medicine star aniseed, white naphthalene, Angelica dahurica, cloves and so on as food attractants, mixed with 10% to 20% of fish medicine, the effect is better.

4. Combination of traditional Chinese and western medicine

The use of traditional Chinese medicine in some western medicine can not only improve the curative effect but also reduce the cost of medicine. Such as rhubarb, Cortex Phellodendri, andrographis paniculata and other traditional Chinese medicine into powder, mixed with sulfonamides, furan Western medicine, can increase the curative effect than the use of Chinese herbal medicine alone.

5. Drug administration method

When preventing diseases, ordinary baits should be given first, and then baits should be given to strong fish, so that those who are weak and have poor appetite should be given more baits; when treating diseases, they should be fed with baits first, so that healthy and newly sick fish should take more baits to give full play to the therapeutic effect of fish medicine.
