fish ectoparasites? To treat fish ectoparasites, we need to use some insecticides on their attachment sites, or pull them out directly. Parasites are generally divided into two kinds, namely ectoparasites and endoparasites, the latter is more harmful, the cost of treatment is also very high, usually choose to change fish rather than medication. But sending out is relatively easy to treat, but the dosage of medication should also be controlled, otherwise it may cause phytotoxicity and threaten the health of fish.
are the common parasites? 1. Cryptoflagellates: Cryptoflagellates usually parasitize the gills of fish. After being parasitized, the body of fish will turn black, while the gill filaments will remain bright red, but there will be some gray-white mucus. If you want to prevent and cure it, you'd better soak it with copper sulfate solution before stocking, and sprinkle the whole pond with drugs during the high incidence period of the disease.
2. Trichodinids: Trichodinids will parasitize the fish body or gills and absorb nutrients from the body. The parasitized fish will gradually become thin and weak, and will move alone in groups. Their appetite will be weakened, and their movements will be relatively slow. In view of these situations, it is better to use potassium permanganate, salt water and other drugs to kill insects.
3, Ichthyophthirius: Ichthyophthirius is one of the more common parasites, parasitic location will appear white pustules, so this disease is also called white spot disease. Because it is afraid of high temperature, it can be eliminated by raising the water temperature properly, and it is better to keep the water temperature at 28 C.
