? Koi usually lay eggs when they are 2-3 years old. Koi are oviparous, with females becoming sexually mature and laying eggs at the age of 3. Males reach sexual maturity relatively early and have the ability to reproduce at the age of 2. When the gonads are mature, they can reproduce naturally. The gonads of Koi mature once a year, and they can reproduce their parents once a year. The best month for laying eggs is from April to June every year.
fish and put them into water? Generally, small fish can be hatched in 5-7 days. After laying eggs, the eggs should be fished out separately and put into the prepared breeding tank to avoid the eggs being eaten by the koi. In the process of hatching, the water temperature should be stabilized at 22-25 C to ensure good water quality and wait for the arrival of small koi.
should we pay attention to when breeding koi? 1. Parent fish: The best time to breed parent fish is from autumn, because the water temperature at this time is more appropriate, mostly around 25 C. They have a strong desire to eat and develop quickly. It can be fed with vegetables, lean meat, fruits and other foods.
2. Fertilized eggs: Fish eggs are sticky and will adhere to the wall of the tank. At this time, they can be fished out by hand and put into a special breeding tank. After the fish eggs are put in, they should be observed frequently, and the unfertilized white eggs should be fished out in time to avoid polluting the water quality.
