Key Technical Points for Overwintering and Emergence Period Management in Wood Frog Farming
1. Overwintering period management: After October each year, when the temperature drops below 15°C, wood frogs descend from the mountains one after another. During this time, aside from commercial frogs being harvested, the remaining breeding frogs and young frogs all move down to the edges of gullies and streams, preparing to select overwintering sites for hibernation. Overwintering of wood frogs in enclosed-gully frog farms
