Breeding is not recommended. This is because the adaptive temperature zone in Shi Wa is very narrow and needs to be within the range of 16-26 degrees. The high temperature section can be increased, but the low temperature section cannot be reduced. It takes a short time to keep the temperature above 20 degrees in Northeast China, which will lead to slow growth and high cost in Shi Wa. For example, when the temperature in Liaoning is stable above 20 degrees, I'm afraid frogs can't lay eggs until early June. Even if they lay eggs and hatch successfully, tadpoles in Shi Wa will last for four months, which means they will hibernate in Liaoning and become abnormal. In addition, according to the fact that the temperature in Liaoning Province will reach below 10 degrees in about 10 months, the low temperature will cause Shi Wa to hibernate for 8 months. There is no evidence that Shi Wa can adapt to such a long hibernation period. Of course, this is based on the physiological characteristics of Shi Wa and the temperature characteristics of Liaoning. Finally, there is no precedent for farming in Northeast China. If you have enough financial strength, there is no need to try to cultivate in a greenhouse to see if it is feasible.
