Egg hatching and disinfection

In recent years, due to the increase in the number of artificial collection of natural silk coats and the collection of linseeds, the demand for wild crickets has been rising year after year, and the selling price has also been rising. Plus the consumption of quail meat by urban and rural residents in some areas, the number of wild crickets has decreased. Almost extinct. It is imperative to promote artificial breeding, and artificial breeding must first be artificially propagated and hatched. The key technologies for breeding and hatching of aquaculture are introduced as follows:

After being hibernated, the earthworms emerged or emerged in the early spring each year. Soon after, the males and females hug each other for mating. When the water temperature rises to 10.8°C, the females lay eggs. Eggs are often produced on aquatic plants in the water. The eggs are small, arranged in double rows and in strips. Therefore, some aquatic plants should be stocked in the pond so that the females can have their spawning sites. Otherwise, the eggs will sink to the bottom of the water and often cannot be hatched due to lack of oxygen.

Because there are many pathogens in the waters of nature, such as hydromycetes, cotton molds and other microorganisms, the eggs are severely infested. Under natural conditions, the hatching rate is less than 50%, and the survival rate of earthworms is very low. Therefore, the freshly-produced quail eggs should be sterilized by using salt (1:2000) and sodium bicarbonate (1:2000) to mix water, soak for 10 minutes, and then put in the pool. Keep it 50 cm to 60 cm deep. On the second day, the whole pool was disinfected, and every 667 cubic meters of water was treated with a net of 20 ml of ciliated water.

In this way, after 15 days, the cocoon hatched. During hatching, adults, frogs, snakes, and carnivorous fish should be prevented from entering the pool to prevent swallowing.
