Last Updated: 2024/11/24, The suitable water temperature of brocade carp is 530 ℃, and the optimum temperature is 2025 ℃, but it is not adaptable to the sharp change of water temperature. If the temperature rises or falls by more than 3 ℃, the fish will get sick; when the temperature exceeds 10 ℃, the fish will die. PH can be raised in 6.88.0 water body.

The suitable water temperature of koi carp is 5 ℃ 30 ℃, and the optimum temperature is 20 ℃ 25 mol, but it is not adaptable to the sharp change of water temperature.

If the temperature rises or falls by more than 3 ℃, the fish will get sick; when the temperature exceeds 10 ℃, the fish will die.

PH can raise Cyprinus Carpio in 6.8Mel 8.0 water body, but it is most suitable to live in weakly alkaline and low hardness water with pH 7.1Mel 7.3.

Koi grows slowly in strong sunlight and can build a shade canopy at Tong Kok or feeding area.

Koi is omnivorous. Molluscs, aquatic plants, benthos and microalgae are the delicacies of koi.

Koi eats more food in summer and little or no food in winter. Therefore, feeding can be increased or decreased according to different seasons.

The bait can be fed three times a day when the water temperature is above 12 ℃ in spring, and only once a day when the water temperature is below 12 ℃.

Reproductive habit

Koi males reach sexual maturity at 2 years old, females reach sexual maturity at 3 years old, in vitro fertilization, viscous eggs are laid, the eggs are white or light yellow, about 2.5mm in diameter, and they spawn once a year. The spawning period is usually from April to June, and sexually mature females usually lay eggs at 4-10:00 in the morning.

The eggs are fertilized in vitro to form fertilized eggs. The fertilized eggs develop on attachments such as aquatic plants or artificial fish nests. After 5 days of incubation, the larvae break their shells.

Or artificial propagation can be used to cultivate fish fry and increase the yield of fish fry. Newly hatched larvae can be fed on wheels, small cladocera or crushed egg yolks.
