In order to get better results, you must breed your own oysters. The breeding technology of Astragalus is very difficult, and several measures to increase the spawning volume of Astragalus have been explored in the combination of years of practice and theory.
1. To create a good environment: plant plants in the Yellow Dragonfly pond, such as rice, water lettuce, water peanuts, etc., and put some stones, bricks in the bottom of the pool, simulating the natural ecological environment in order to facilitate the spawning of Astragalus.
2. The stocking density should be appropriate: individuals should be moderate to the nymphs, it is best to choose 100g-150g jaundice for spawning pro-family, male to female ratio of 1:2-4 stocking density of about 10 per square meter
3. Adjust water quality water level: The breeding pond water must be non-toxic river water, lake water, do not use groundwater, and the pH value should be between 6.5-7.8, water depth 20cm-30cm, the new cement pool to carry out dealkalization.
4. Feeding feed should be reasonable: from April to September, the breeding season of A. japonicus is to feed artificial complex feeds with higher protein content, and to add some animal feeds such as fish paste and earthworms. Sexual mating nymphs, after being fed with high-protein diet, usually lay eggs within 5 days to 7 days. The eggs are produced on the side of grass or stones. As long as there is white foam, it is the production of ovary of the nymphs.
5. Strengthen the parent's prenatal cultivating: In the autumn, increase the protein content of the parent feed, feed a small amount in the winter, feed in the spring, and increase the protein content of the feed to promote the development of the jaundice to restore constitution and gonads, laying the foundation for reproduction.
