The density of koi breeding needs to be arranged according to the actual situation, including factors such as the size of the aquarium, the size of the koi, and the strength of the filter. Here are some specific reference data:
Aquarium density:
A 60 cm x 30 cm x 15 cm aquarium can hold 6 koi with a body length of 15 to 20 centimeters.
A 90 cm x 30 cm x 50 cm aquarium can hold 8 koi.
A 110 cm x 30 cm x 50 cm aquarium can hold 10 koi.
Pond breeding density:
When the fish species is 5 to 15 centimeters in size, the stocking density is 1000 to 1200 fish per mu.
Cement pond breeding density:
Stock 5 to 8 fish per square meter.
In addition, koi have a large appetite. It is recommended to feed them in small amounts and multiple meals to avoid water quality problems caused by excessive feeding. High-density breeding may lead to weak constitution and easy disease occurrence in koi. Therefore, maintaining a reasonable breeding density is very important for the health of koi.
