How do domesticated koi fish breed? You need to learn these methods
Koi are regarded by everyone as a symbol of good luck, and they can often be seen on many occasions. So do you know how domesticated koi fish breed? Let's take a look!
1. How do domesticated koi fish breed
Domesticated koi can reproduce naturally. Prepare a fish nest, and when the water temperature reaches between 18-35 degrees, breeding work can be arranged. Eggs are most easily laid on the morning of thundery weather. After the fry hatch and can swim horizontally, start sprinkling egg yolk water; after feeding continuously for 3 days, they can be transferred to the fry pond for rearing.
2. Four-season management of koi
1. In spring, the weather turns warm but still cold, and koi begin to revive from hibernation. Rearing is moved from indoors to outdoors, but special attention must be paid to sudden temperature drops. Cover with plastic film in time to keep the water temperature stable; feed mainly plant-based bait, gradually increasing the amount from small to more, to help koi digest and absorb.
2. In summer, the weather is hot and scorching, so plastic shade netting must be added to prevent direct sunlight, making the sunlight illumination drop from 8000-12000 lux to 5500-5800 lux, which is most suitable.
3. In autumn, the weather has little rain and is mostly sunny, and the water temperature drops noticeably. This is the most suitable time for koi growth, and the proportion of animal-based (protein) food such as silkworm pupae can be increased. Increase the feeding amount to promote rapid growth.
4. In winter, the weather is relatively cold. When the temperature drops to 0°C, koi should be transferred indoors in time to an indoor fish pond for overwintering. The indoor water temperature should be kept at 2°C-10°C. The focus is on keeping warm, feeding appropriately, maintaining body fat and preventing disease. The period from November to March of the following year is the overwintering period for koi.
