1, male and female identification The difference in appearance of male and female snails is not significant. The stage of juvenile snails is difficult to distinguish. The most obvious difference is that: in the same feeding conditions, the females in the same age snail are generally larger than the females; the centipedes of the female snails are recessed and the male snails are stung. Central convex, slightly concave around. 2, the choice and cultivation of snails and snails The deer and snails should choose individuals older than 4 months old, with large individuals and intact shells and shells, with a ratio of 2 to 4:1. The conch cultivation pond (also known as the spawning pond) can be earthen pond, cement pond, ditches, etc. The area should not be too large. The rectangle is better, the water depth is 30 to 50 centimeters, and the wood and bamboo strips are inserted around the pool and in the center. Female snails adhere to spawning, and there should be anti-escape facilities around the earthen pond. It is more appropriate to have a relative density of 30/m2. Feeding a sufficient amount of green fodder each day should also be manually fed with concentrated feed. The daily feed of concentrate should be 0.5% of the total weight of the screw. During the cultivation, it ensures fresh water and quiet environment. 3, egg collection and hatching From March to November each year, male and female snails spawn and produce eggs, and the eggs that are produced must be collected in time and hatched in other pools. Oviposition time should not be too early, too early egg mass is too soft, not easy to peel off, it should not be too late, too late egg block has completely dried up, easy to break eggs when peeling. Generally 10 to 20 hours after spawning, collection is ideal when the egg mass is not fully hardened. The collected egg pieces are placed on a mesh or bamboo screen, and a layer of gauze is placed on top to be incubated above the indoor water basin. It can also be set up 30 to 50 cm above the young snail breeding pond to hatch, pay attention to the shade and shelter from the rain. In the temperature of 28 ~ 30 °C, 7 ~ 10 days of hatching, when the red eggs become lighter white, the young screw will break out of the film, fell into the water, 2 days later, the young screw top changed from red to black Start eating.
