Safe use of fishery drugs to scientifically prevent and treat fish diseases

4.Viral diseases: grass carp hemorrhagic disease, turtle mumps, shrimp white spot disease, etc. 6.Protozoa: Trichozoa, Cryptotrichuris, Cucurbita, Sporaria, etc. Different drugs are used for different pathogens. 7. Frukes: such as ringworms, are currently a serious and difficult disease in eel farming. In the past two years, there have been special drugs such as Insect Killer, Vermicide King, and Insecticide Pioneer. The most typical common problem of these drugs is that they do not indicate the ingredients, and they are inferior drugs, but there is still a lot of market. Fungal diseases are often complicated by bacterial diseases. When complications occur, the fungi need to be treated first and then the bacteria. 2.Sporidia has become a major chronic disease in the aquaculture industry, especially infection in the gills, which often affects food intake. Currently, disporin is used to treat sporozoites. In order to achieve better efficacy, salt baths are more effective. The first effect is to destroy the cysts in the gills, causing them to fall off or a single spore to flow into the spleen through the blood, and the spleen will eliminate it. When treating sepsis, many farmers lower the water level during treatment in order to save medication costs and do not change the water during the medication bath. This approach often leads to greater deaths and more serious losses. This is mainly because the water at low water levels is dirtier, affects breathing and toxin excretion, and even produces smelly ammonia. Therefore, you must pay attention to changes in water quality during medication. For monogeneous flukes such as Anthonylia and Benedenia, praziquantel, benzodiazepine, etc. can be taken orally.
