raise koi in outdoor fish ponds? First of all, we should sterilize and disinfect the koi, and prepare a strong filtration system. Because the area of the fish pond is large, and there are more dust, bacteria and harmful substances outdoors, it is easy to destroy the ecological balance in the water.
The second is to prepare the fish pond cover, when the temperature is low, the outdoor fish pond is difficult to heat, the breeder can add the fish pond cover to prevent the fish pond from freezing. When the temperature is high, it is necessary to add a net cover, which can not only avoid the rapid reproduction of algae in the fish pond, but also prevent the fish pond from warming up.
Finally, we should pay attention to the water level and density of feeding, the water level should not be too shallow, and the density of feeding should not be too high. Because the water level is too shallow or the feeding density is too high, the koi will suffer from hypoxia.
Outdoor is easily affected by the weather, especially in rainy summer, when the air pressure is low, the appetite and activity of koi will be reduced. Breeders need to pay attention to reducing the amount of feeding, but also pay attention to more oxygen, because the air pressure is low, oxygen will also be reduced.
When it rains, it is better to take shelter from the rain, because the rain is acidic, which may corrode the gills of the koi, leading to gill rot. Therefore, when it rains, breeders are advised to build shelter tools above the fish pond.
