Frogs are oviparous, and the greatest feature of reproduction is hermaphroditism and in vitro fertilization. Before breeding, frogs will hold each other. At this time, breeders can not disturb them, because holding each other will promote ovulation of female frogs. Frogs usually lay their eggs in water, but some species of female frogs build a nest before ovulation, and then lay their eggs in the nest. Frog eggs are fertilized before hatching, and the first form of hatching is tadpoles.
How do frogs reproduce and hatch after reproduction?

1. How do frogs breed

? Frogs usually breed in mid-April or late April every year. Frogs will have a special phenomenon during the breeding period, that is, holding pairs. Many people think that hugging is mating, but in fact, hugging is only a part of the reproductive process. But if the breeder forcibly separates the frogs, the female frogs may not lay eggs even when they are in the spawning period, so holding pairs is a way to promote female frogs to lay eggs. Female frogs lay their eggs in the water after cuddling. After the eggs are fertilized in the water, they can hatch into tadpoles smoothly.

2. How to hatch

frogs after breeding? Frogs will not take care of their eggs after laying eggs. If they are hungry, they may eat their eggs. Therefore, breeders need to prepare a separate container for frog eggs. The water temperature in the container should be controlled between 20 and 30 degrees Celsius. The higher the temperature, the shorter the incubation time. However, the maximum temperature should not exceed 35 ℃. PH value should be controlled between 6.5 and 7.5, and the water quality should be clean and refreshing. As long as the water temperature and quality can meet the requirements, frog eggs can be hatched in about 3-5 days, but even if they are born at the same time, it is impossible to hatch at the same time, breeders need to pay attention to whether the unhatched eggs are still healthy.
