How do American frogs reproduce naturally?

When the water temperature is stable above 18℃, Rana americana enters the breeding period, and aquatic plants are put into the frog breeding pool as appendages for Rana americana to lay eggs.

As long as there are shallow waters and aquatic plants, and the water temperature is stable above 18℃, mature male and female American frogs can naturally embrace, lay eggs and fertilize in the same water body.

In the natural state, the spawning season varies slightly from place to place. In Guangdong, it started in the middle and late March, and in Jiangxi, the water temperature rose to 16 ~ 18℃ around Qingming Festival, and male and female frogs laid eggs in pairs.

Later, with the increase of water temperature, the spawning activity of this group gradually reached its peak. Most American frogs lay eggs in the early hours of the morning and rarely in the afternoon. Especially in sunny mornings after rain, spawning activities are extremely active. On rainy days, they lay fewer eggs.

Supplementing the pond with fresh water every night is beneficial to stimulate the parent frog to lay eggs. Keep the environment quiet in the process of cuddling, so as to avoid the separation of cuddling parent frogs due to human interference, which will affect the reproduction of American frogs.
