Koi common disease: blood disease is mainly caused by fluorescent bacteria. First trick: 3-5% saltwater medicated bath for 15-10 seconds or strong chlorine 1ppm medicated bath. Sterilize the whole pond. Koi common disease: scale-standing disease is mainly caused by Pseudomonas punctata infection. It is caused in winter when the water temperature is low or the temperature difference during water changes is relatively large. Second trick: 10ppm potassium permanganate medicated bath for 10min for koi, rinse after the medicated bath (with pond water), then apply nitrofurazone dry powder to the affected area. Koi common disease: fish lice are mainly caused by fish lice parasites. Third trick: deltamethrin, cypermethrin 0.02 ml/t, kill again after 7 days. Sterilize the whole pond to prevent wound infection. Koi common disease: carp pox disease is caused by herpesvirus infection. Fourth trick: strengthen the constitution, 50mg erythromycin in 25kg pond water for soaking bath. Large fish can be injected with 0.2 parts per million levomycetin. Koi common disease: print disease, also called rot skin disease, is mainly caused by Gram-negative bacteria infection. Fifth trick: prevent fish bodies from collision injuries, increase the oxygen content of the breeding water, mix furazolidone into feed, sterilize the whole pond.

Koi common disease: water mold disease is mainly caused by Saprolegnia infection. Sixth trick: malachite green 1/15000 medicated bath, whole pond nitrofurazone 3-5ppm or iodine preparation for sterilization. Koi common disease: enteritis is mainly caused by too large a change in the amount of feed given, spoiled feed, sudden change of bait, low oxygen content in the water, water pollution, etc. Seventh trick: pay attention to the above causes. Stop feeding and mix furazolidone into feed. Koi common disease: swim bladder disease is mainly caused by too large a difference in water quality changes, sudden fright, overeating, causing swim bladder dysfunction. Eighth trick: raise the water temperature, increase the oxygen content of the breeding water, maintain ideal water quality, feed a small amount, induce sick fish to eat and move, and enhance their constitution. Koi common disease: white spot disease is mainly caused by parasitic Ichthyophthirius multifiliis, most likely to occur in late spring and late autumn. (Identification of koi white spot disease symptoms) Ninth trick: do not add new fish if possible. Extend the drying period of tap water, let the water "mature" thoroughly. During treatment, raise the temperature by 2-3 degrees per day until 28-30 degrees, and Ichthyophthirius multifiliis will detach from the fish body by itself. Koi common disease: cold disease is mainly caused by the water temperature rising or falling too quickly during water changes. Tenth trick: when changing water, new water should be added slowly. Newly introduced fish must have enough time to equalize temperature before being placed in the pond. The indirect temperature difference should not exceed ±3°C, pay attention to weather changes, and prevent sudden rises or drops in water temperature (especially for tank keeping). Splash dually quaternary ammonium iodine (dual quaternary ammonium salt complex) 0.1 ppm over the whole pond. Once you learn the above ten tricks for dealing with common koi diseases, you can basically handle yourself with some ease in koi keeping. (Reposted from the internet)
