The technique of koi culture in autumn is the skin contagion of common diseases of koi.
Prevention and treatment:
(1) dissolve 0.2 grams of furacilin powder and 250 grams of salt in 10 kilograms of water, wash diseased fish for 20 minutes, or sprinkle with low concentration medicine. after repeated use, the skin blood spots will gradually fade and restore the original color.
(2) prolong the time of light exposure in the aquarium.
(3) the diseased fish were washed with low concentration potassium permanganate solution for more than 10 hours.
(4) sprinkle with edible fine salt water, generally put salt 50 Mel 100 grams in the aquarium of 100*50*35CM.
(5) choose 0.5-0.8 grams of crystal trichlorfon, dissolve in 10 kilograms of water and wash the diseased fish for 10-20 minutes. Or choose 0.2 grams of crystal trichlorfon, dissolve in 1 ton of water, sprinkle the whole pool.
Autumn is the most favorable season for the growth of koi. The temperature is generally between 20 and 28 degrees Celsius. At the same time, it is also a period of high incidence of various diseases. Fish usually have two peak periods in a year, and autumn is the last. Although the disease in autumn is not as serious as that in spring, if it is not found in time and treated, koi is likely to carry germs through the winter. And it will break out again after the weather gets warmer next spring. If your fish are not fattened before winter, when the koi gets warmer next spring, the koi will be in a state of weakness because it consumes a lot of energy in winter. However, once the fish disease breaks out, no matter what the disease is, there will be no cure for the possibility of death soon. Therefore, we must do a good job in fattening koi in autumn and prepare for the coming winter.
