People usually want to raise koi fish in large quantities for viewing. However, if the stocking density exceeds the carrying capacity of the water body, the water quality and system will be out of control, and the narrow space will easily cause environmental pressure on koi fish and reduce the resistance of fish. At the same time, the narrow space causes frequent joints between fish, which makes it easier for pathogens to spread quickly. High-density farming will not only weaken the constitution of most koi fish, but also cause diseases, so it is very important to keep a reasonable breeding density in koi fish for disease prevention. So what is the best breeding density in koi fish? The following table shows the contents for your reference.
