Six measures for raising soft-shelled turtle to increase the fecundity of female soft-shelled turtle
The main results are as follows: 1. The ratio of female to male should be appropriate in the soft-shelled turtle pond, but more male soft-shelled turtles affect the mating of parent soft-shelled turtles and reduce the fertilization rate. In general, the ratio of female to male is (3: 4): 1. If the male soft-shelled turtle in the pond is strong and large, the number can be less. On the contrary, the number of male soft-shelled turtle should be increased. If it is found that there are more claw marks on the nail back of the female turtle in the pond, it means that there are too many male soft-shelled turtles.
2. Female soft-shelled turtles fed with sufficient protein feed need more protein and calcium to lay eggs. In order to meet the needs of spawning, animal feed such as snail, clam, small fish and shrimp must be supplied regularly, quantitatively and at a fixed point. 3. Do a good job in water quality management to ensure that the water of the parent turtle pond is pollution-free, moderate in fertility and light green or tea-green. The transparency of the water is 25cm to 30cm, so there are many microbes in the water. If the water is too thin, you can sprinkle fresh human feces and urine or accumulate bar manure on the pond bank to let the fat water flow into the pool. The depth of the water is moderate to raise the water temperature. Change the water once a week and keep 1/10 of the pool water when changing the water. 4. Tidying up the spawning ground is also the "sun-tanning" field for soft-shelled turtles. Before spawning, the egg field should be flattened, spread 40-50 cm thick fresh sand, and keep moist. 5. Keep soft-shelled turtle pond quiet when mating and spawning soft-shelled turtles, be very afraid of sound interference. Therefore, in the breeding season, it is necessary to eliminate the natural enemies in the turtle farm in order to reduce interference and avoid the harm of natural enemies. 6. To increase the lighting time, electric lights should be installed on the water surface of the turtle pond, and the lights should be turned on at night, which can not only increase the lighting time, but also induce insects to feed the turtles, killing two birds with one stone.

Aspects that tortoise farmers should pay attention to when collecting turtle eggs
Every year from May to October is the spawning season for turtles. Most of the turtles lay eggs in the early morning, evening and night, and a few at noon, so the time to collect eggs should be after 3 pm. Before collecting eggs, the egg collection tools should be cleaned, and the egg collectors should put on clean shoes and go into the person to lay eggs.

First, reproductive characteristics: adult male partridge weighs 0.75 kg, female partridge 0.6 kg, artificially raised partridges can produce more than 80 eggs a year, fertilization rate is above 85%, incubation period is 18 days, hatching rate can reach 90%. Second, the choice of breeding partridges: female partridges must be used for breeding.
