I: Segregated treatment
Autumn is the peak of koi trading, people buy fish at various fish farms, or gifts between friends, etc., koi are moved frequently, and this time of year poses a great threat to the health of koi, so be sure to isolate the sterilization and disinfection.
I: Regular sterilization and pest control
Designate a period of time to gather all the koi together, salt bath them, sterilize them, and then wait until the koi's physical condition is adjusted to normal before feeding them. Moving koi around frequently can have a significant negative impact on koi feeding. Healthy koi from various fish farms, bought and mixed, will come out with disease symptoms. Most people can't avoid mixing koi, so then management is crucial at this time.
III: Methods of prevention and treatment of diseases
Diseases generally have4There are three causes: visible parasites, invisible parasites, bacteria, and viruses (during the spring and fall of the year, when water temperatures are20(The time around ℃ is a high incidence of disease).
- Parasites are visible.Use mazdan, malachite green, or trichlorfon, to kill the insects.
- No parasites are visible.This is more common and can be treated with potassium permanganate. In addition, potassium permanganate can be used to measure the water quality, if the water quality is bad, add potassium permanganate water will turn yellow immediately. These worms are always present and will multiply when the koi is not in good condition, the fish will become congested and have bad fins. In this case, you can use potassium permanganate, add new water, and enhance the filtration function to improve the water condition.
- Germs.For example, perforation disease, with0.5%of salt, and stabilized diacidified chlorine. As well as antibiotics to warm the water, kill bacteria and prevent secondary infections.
- Virus.There are vaccines for some viruses, but they are only preventative, not curative. Some viral diseases recover naturally on their own, while others do not. For exampleKHV. There is no medicine for this, but only heating treatment. However, it is difficult to set the temperature of the water and the period for warming treatment, etc., and in Japan, warming treatment is generally not used.
IV: Sensitization and jumping out of koi in the pond
- Koi that have been released into a new pond or tank will initially panic because they are not used to it, and will recover over a period of time.
- If the old fish have sensitivity, it is likely that there is a problem with the water quality, so please inspect the filter tank first to see if it has been cleaned.
- Phenomena such as jumping out or bumping into walls can also be caused by parasites.
- If none of the above phenomena are present, then the main cause should bepHThe problem of an intense decrease in value. This one is usually overlooked, so regular measurements ofpHvalue is necessary, focusing on the magnitude of the decline.
