1. Disinfect and change water 1. Reason: The scales and rotten meat of brocade carp may be caused by post-traumatic infection, and trauma usually occurs during fishing or transportation. Or trauma caused by other sharp decorations in the water.
2. Solution: Breeders need to change water for sick fish first to avoid bacterial re-infection. Then use furacilin powder to take a medicated bath for sick fish, which lasts for 15-20 minutes every day and lasts for about 3 days, and the rotten parts will be improved.
II. Potassium permanganate solution medicated bath1. Reason: The scaly and rotten meat of koi may also be caused by bacterial infection, which is mainly due to poor water quality or unclean food.
2. Solution: The breeder needs to clean up the rotten parts first, and then apply potassium permanganate to the affected parts once a day for about a week, and the rotten parts will show signs of healing.
3. Chlortetracycline or Galla chinensis treatment1. Reason: Koi may suffer from red skin disease after losing scales and rotting meat, mainly because parasites and bacteria are infected at the same time. This kind of situation is easy to appear in spring and autumn, so breeders can observe it carefully and treat it in time once it is found.
2. Solution: The breeder needs to change the water for the sick fish first, and it is best to transfer them to a separate container. Then sprinkle Chinese gall directly into the fish tank, and change the water once every 2 days during the treatment. Every time you change water, you can supplement the same amount of medicine. After waiting for about a week, koi can recover. Chlortetracycline can also be injected directly, but the amount of injection needs to be determined according to the size of koi and the severity of the disease.
