How to Treat Fish Nocardiosis?

In the treatment of fish nocardiosis, the first step should be to stop feeding to prevent the continuous increase of ammonia nitrogen from eating sugar, and then adsorb part of the ammonia nitrogen. Moreover, the pond needs a large amount of water change, adding some vitamins and liver-protecting drugs, which are put into the feed together. This can achieve a certain therapeutic effect.

By observing the epidemic characteristics of nocardiosis and the symptoms of organs such as body surface, gills, heart, liver, kidneys, and spleen, and comparing the symptoms of nocardiosis, a basic judgment can be made. If a diagnosis is required, molecular biological methods should be used for the isolation and identification of the pathogen.

The best control method for this disease is vaccine immunity. However, the vaccine for nocardiosis is still under development, and there are no commercialized vaccines available for use.

After years of clinical practice, the symptoms of nocardiosis are obvious and typical, and can be judged through careful clinical observation. In actual production, early treatment for diseases and prevention for non-diseases are essential to effectively control the transmission of nocardiosis. Regular attention should be paid to improving water quality, controlling ammonia nitrogen and nitrite within the normal range, regular disinfection, and reducing the number of nocardia in the water to effectively prevent the outbreak of this disease.
