of frogs is oviparous, which is sexual reproduction, hermaphroditic and in vitro fertilization. When the water temperature is 20-28 ℃, it is the peak season for frog breeding. In the north of China, summer and autumn are the most suitable seasons for frog spawning. Especially after the rain, frogs will attract the attention of their companions by croaking and holding each other. After
a few hours, or perhaps 1-2 days, the female begins to lay eggs and the male begins to ejaculate. Eggs are fertilized in water. After fertilization, the eggs will gradually expand and become larger. There will be small black spots similar to sesame seeds in the eggs. The tadpoles will be born in about 3-4 days. The little tadpole slowly sheds its tail and grows into a frog.
for breeding frogs 1. After selecting the parent frogs, feed them separately for a period of time, about ten days before the birth period, and then put them into the breeding tank to hasten the birth. This is to prevent male and female frogs from flirting with each other, resulting in inconsistent breeding periods and abortion.
2. After breeding, frogs must be raised separately from eggs, in order to protect the tadpoles and prevent frogs from eating them as food.
3. The number of frog eggs directly determines the number of breeding frogs. The eggs at the bottom of the fish tank should be rescued in time to avoid the death of the eggs due to lack of oxygen.
