Astragalus pure natural stocking effect

The species can be selected from the self-supported species. In the breeding season (May-September), a large number of yellow crickets were selected and placed in breeding ponds for breeding. If there are two or more batches of pods of different sizes, the females can be selected from the smaller pods and the male pods can be selected from the larger pods.

Kind of delivery

The input density of the species in the breeding pond should be 6 to 10 per square meter. Some dwarf grass plants can be planted on the mud piles in the pool, and the tall plants affect the fresh pond lighting and affect the reproduction of the yellow peony.

Breeding

After entering the pond, the species were generally not fed for the first 2 days, and a small amount of earthworms were fed on the third day to facilitate attracting. Set the feeding pool of the seed pond to the inlet hole. Feeding time can be 1 hour to 2 hours before dark, after the feeding, open the inlet pipe, so that the feed breath with the water throughout the pool to attract species to feed. After eating jaundice normally, other feeds may be added as appropriate. Mix the other feeds in the pots before feeding, and allow them to crawl for a period of one hour so that the other feeds have a strong smell. Other feeds should gradually increase. It is advisable to have the amount of feed not to be left after eating, and it is found that there is residue that should be removed the next morning.

Spawning period management

The production of ovaries: The production of ovary shows that spawning will take place in about 3 days. During this time, the visits should be stopped and the materials must be light. During this period, there are two jaundice probes in the mouth. If there are other eagles close to each other, then the original male locust will be violently attacked. Generally, the offender will retreat without attacking, and there will be more powerful ones instead.

The emergence of bubbles: Once there is a bubble in the opening, it is proved that the yellow locust will spawn in about one day.

The female scorpion is away from the nest: If only one baboon probe is found to breathe at the hole, the female scorpion is certified to have spawned and left. After another 5 days to 7 days, the seedlings will be hatched.

Harvesting seedlings

Seedlings hatched within 5 days can be harvested into a seedling breeding pond culture. The water temperature in the seedling cultivation tank should be the same as the seed pond temperature (with a difference of no more than 2°C). When using the small net made of fine gauze, the movement should be agile, so as not to affect the fishing seedlings due to the attack of the nursery species. Spawning species should be carefully fed, and a second spawning operation can be performed approximately 20 days later.
