2, turtle seedlings into the pool: the yellow-shelled turtle is very delicate, and the back armor and abdomen armor are soft. Feeding in the cement pool is easy to scratch the abdominal nail, limbs and claws. Therefore, it should be placed in enamel pots and plastic pots with a water depth of 2~4 cm. When adding water, pour it slowly, not too fast. So as not to choke the turtle seedlings. Sprinkle fine sand on the basin. The fry should be soaked in 5 mg/L potassium permanganate solution for 5 minutes before being put into the basin. After temporary cultivation 1~2 weeks, move into cement pool.
3. Breeding of turtle seedlings:
(1) Newly hatched turtle seedlings generally do not prey, and the energy and nutrition needed for their early growth and development are completely provided by yolk. It was found that the yolk consumption of the fry was 40~56% in the first week and disappeared on the fifteenth and ninth days. According to this result, we can infer the utilization of surplus egg yolk by observing the change of egg yolk size when young turtles are raised, so as to determine the feeding date and feeding amount. (2) After temporary rearing, the turtle seedlings are more active and have strong feeding ability. Generally, cooked egg yolk, red worms, fly maggots and lean minced pork are fed, and high-fat bait or pickled food is fed to avoid symptoms such as indigestion. In early spring, the soft-shelled turtle just woke up, with weak activity and unstable body temperature, so it is not suitable to feed more. Feed it l times every three days, 1 1~ 14.
4. Water quality management of turtle seedlings: Young turtles eat more, emit more pollutants, and the water quality is easy to deteriorate. After each feeding, the residual bait should be removed in time. Thoroughly clean the bottom of the pool and disinfect it when changing water. In summer, due to the high temperature. Shading shed should be built to increase the water depth appropriately. A heated pond. Pay special attention to the difference of fresh water temperature when changing water, which generally does not exceed 2~3℃. Due to the shallow water level in the turtle pond. The water temperature changes rapidly, and it is measured in Qin Ying in early spring and autumn. Especially when heating in winter, the temperature of water surface and bottom must be measured, and the temperature difference should not exceed 3~5℃. Otherwise, the tortoise will get sick easily.
