In order to obtain better benefits, it is necessary to breed their own species of yellow peony. The breeding techniques of jaundice are more difficult, and people have summarized six methods to increase the spawning volume of jaundice in practice.
1. Choose the venue: plant plants in the pond, such as: water floating Peng, water peanuts, etc., and put some stones, bricks in the bottom of the pool, to simulate the natural ecological environment in order to facilitate spawning.
2. Adjust water quality and water level: Aquaculture pond water should be non-toxic river water, lake water or groundwater. PH value of water should be 6.2-7.8, water depth is 20-30cm deep, and the fresh water pool should be treated with alkalinization.
3. Stocking density should be appropriate: Individuals should be moderate to the nymphs, it is best to choose 100-150 grams of jaundice for spawning and pro-spawning. At this time, the proportion of male and female jaundice is 1:3-4, and the stocking density is about 10 for each parent. , too much impact on production
4. Feeding feed should be reasonable: In the breeding season of A. sinensis in April-September, feeds with higher protein content, such as fish paste, sorghum, etc., should be fed. At the same time, with the full-priced compound feed of Astragalus mongolicus, sexually mature A. erinaceus should undergo high protein feed. After 5 to 7 days after feeding, eggs are laid. The eggs are laid on the side of grass or stones. As long as there is a white foam, it is the production of ovary.
5. Grasp the water temperature: During the spawning season of Astragalus mongolica, patrol the pond every morning in the pro-Huangqi Lake. If ovary with white foam is found, it should be gently moved into the hatching pond and incubated with microfluidic water. The fertilized egg expands to about 4 mm after inhalation, and the incubation time changes with the temperature of the water, generally 1-7 days. When the water temperature is 25°C, it is completed in 6 days. After hatching the seedlings, the water temperature 28 °C after 10 days, the body up to 26 mm, the yolk sac has not completely disappeared; after 7-10 days the yolk sac will be completely finished, began to feed plankton in the water, can be appropriate small amount of investment Feed the little otters. After about 35 days, the young larvae grow to 5-6 cm, and they can be kept in feeding ponds, and they must be placed separately.
