One can raise five koi of about 20-30 centimeters, or 10-15 koi of about 10 centimeters. If the size of the koi reaches 1 meter, it can only raise 1-2. But if it is a small fry, the number of breeding is more. So how many koi can be raised in a ton of water depends on the size of the koi. In addition to the size of the koi, but also depends on the height of the water level and the size of the breeding space, if the water level is lower, then the breeding space is larger, the number can also be increased. If the water level is high and the fish pond space is small, the number of fish raised needs to be reduced.
should we pay attention to when raising koi in fish ponds? 1. Climate change: The most uncontrollable thing in outdoor breeding is the change of temperature, so breeders need to prevent the temperature difference caused by the change of temperature in advance. Because Koi can tolerate cold and heat, but it can't accept a sudden drop in temperature. And when it rains outside, it needs to be covered with a shed, because rainwater is acidic, if the water in the fish pond is mixed with a lot of rainwater, it will cause the water quality to become acidic.
2. Filtration problem: There is a lot of dust outside, and if there is no shed in the fish pond, leaves or garbage are easy to fall off. So breeders need to fish regularly and install a strong filtration system.
3. Feeding problem: Outdoor feeding should be decided according to the temperature, because the outdoor temperature can not be kept constant, so when the temperature is low, the breeder needs to reduce the amount of feeding.
