Breeding technique of bullfrog

Before the tadpoles go into the pool, the pool should be cleaned and disinfected with 200PPM bleach. Tadpoles should be transferred to young frog pond in time after metamorphosis. In order to prevent residual food, tadpoles should be graded according to their size. After becoming a frog, the frog pond should build an anti-escape wall with a height of about 1.5m and a water depth of 1.2m, and increase the amount of feed.

First, tadpole stage

The newly hatched tadpoles are small, black and have poor swimming ability, but their swimming ability increases as the individual grows up, so they can be reared in the incubation pond for about 10 days before they can be transferred to the tadpole pool. Before the tadpole goes into the pool, the pool should be cleaned and disinfected with 200PPM bleaching powder. If it is a clay pool, it should be disinfected with quicklime (75KG per mu). After 7 days, the effect of quicklime disappears (and the water has been tested), and then put into the tadpole.

Second, the period of young frogs

Tadpoles should be transferred to the young frog pond in time after metamorphosis. Generally speaking, newly abnormal young frogs can put 80-100 frogs per square meter. After 30 days of metamorphosis, the young frogs weighing 25 meters and 50 grams can be released at 30 meters per square meter. In order to prevent leftover food, it should be graded according to its size.

III. Adult frog period

Generally speaking, the adult frog pond should be 300 square meters, and the depth of the water should be kept at 1.2m. The pond is overgrown with weeds (can also grow agricultural plants) and has water inlet and outlet, so it is necessary to build an anti-escape wall with a height of about 1.5m. It can breed 20 birds per square meter. The bait of adult frogs is the same as that of young frogs, but the feeding amount is larger, 5% from May to June, 20% from July to August.
