Intimate turtles should be selected from individuals who are over 5 years of age, who are sturdy, disease-free, lively, and physically strong.
The ratio of male to female is generally 2-3:1 for males and females. If the proportion of males is too low, it is unfavorable for normal fertilization of females.
Oviposition time is generally within 10 hours to 30 hours after spawning. It is advisable to harvest eggs within 3 days to 5 days after spawning if conditions permit. It is advisable to collect eggs in the afternoon so as to avoid human interference during the day. Normal fertilized eggs have a white spot on the outer surface of the egg shell. The edges are clear and sleek, and the eggs are bright and pale in color. The white spots on the egg shells are not visible, and the colors are basically the same as the unfertilized eggs. The white spots on the shell are irregular white spots, and the eggs are not hatched.
Large turtle species such as snapping turtles, etc., each occupy at least 2 square meters - 3 square meters of pond area, in order to facilitate the breeding season to chase after the gogo, play and mating. Small turtle species such as turtles, etc., can be stocked in 2 per square meter pool -3, in order to fight for fertilized eggs, the proportion of more than 96%.
The hatching method can be hatched in a wooden box or river sand. The hatchery box is the best for the wood and the pine is the second, and it is not suitable to use poplar or willow. River sand ventilation and water retention performance are good. Turtle eggs can be arranged in 3 cm thick sand and then covered with 2-3 cm thick sand. Note that sea sand cannot be used because the sea sand contains too much salt and it will cause the embryo to die due to salting.
The turtle eggs that are ready to hatch must be sterilized before hatching. The sand used can be sterilized with a 5000-fold potassium permanganate solution, sun dried, and placed in an incubator to kill harmful pathogens. The humidity of the incubator can be controlled at 80%-86%. The incubation temperature is preferably 30°C-33°C.
