After the ornamental shrimp hatch eggs, it usually takes 20-30 days to hatch shrimps. Usually, female shrimps need to undergo shelling after one reproduction to continue mating and reproduction, and the breeding period is from the end of October to March of the next year. If the mating time is too early, the eggs are immature, too late will be aging. In addition, it is better not to fish during the mating period, and let the female shrimp hatch and reproduce as far as possible.
1. Preparation before breeding: Before breeding ornamental shrimps, adjust the water quality, keep the pH at about 6.5, and control the water hardness (GH) between 4 and 8. In addition, ensure the stability of the nitrification system. After the beginning of the layout of shrimp tank, 60 of the tank if there are more than 10 male shrimp, need to put in the tank honeycomb wood, raise less can be a simple layout.
2. Reproduction process: The male shrimp is usually put in when the female shrimp is four months old. At this time, the place where its head and body are connected will be somewhat transparent. After three days, the water should be changed. When breeding, the male shrimp will inject sperm into the female shrimp's genitals, and when its ovaries mature, it will squeeze the sperm out for in vitro fertilization, and then it will begin to hatch eggs. The egg masses are golden yellow at first, then turn black or green.
3. Artificial incubation: If the female shrimp is going to exuviate or die before the eggs hatch, artificial incubation is needed. At this time, you can take out the unhatched eggs and put them in a place where there is water flow, be careful in the process, do not take out the impurities of the four shrimps, otherwise it will easily lead to its long hair. During this period, the temperature is controlled at 26-28 C, which can improve the speed of hatching.
