What conditions must be met for frog farming?

SummaryBreeding pond: The breeding pond should be built in a damp, warm and shaded place. A shade board must be set up over the pond surface, and a small amount of floating aquatic plants should be put into the pond water. Feed management: Different breeding methods are used at different stages, and feed must be given on a fixed schedule, in fixed amounts, and at fixed locations. Frog breeding: Artificial breeding is the main method, and male and female frogs should be stocked at a ratio of 3:1.

I. Construction of the breeding pond

1. Frog breeding ponds are divided into spawning ponds, tadpole ponds and adult frog ponds. Generally, it is most suitable to build them in a place that is both damp and warm with shade from the sun, and a rectangular cement pond or earth pond is most suitable.

2. For a large outdoor pond, 4×6 m makes one single pond. The pond walls are best coated with cement, while the pond bottom still retains soil. A small courtyard pond is generally 1×1.5 m to 2 m.

3. The pond depth is generally about 1 m, and an inlet hole and drainage channel are set up in the pond, with a water depth of about 20-50 cm.

4. A shade board must be set up over the pond surface. Generally, 40 adult frogs can be kept per sq m. Frog breeding ponds can use earth ponds, brick ponds or rice fields; the key lies in preventing the frogs from escaping.

5. If conditions permit, brick walls can be built, or netting can be used, generally at a height of 1-1.2 m. The water depth in the pond is 30-60 cm. A mound of soil is piled in the middle of the water or on the sunny side to serve as land habitat for the frogs, and it accounts for about 1/3 of the whole pond.

6. Grass or crops are planted on the soil mound. A small amount of floating aquatic plants should be put into the pond water.

7. For a pond used to raise tadpoles, only a small area of land is left for the young frogs to come ashore after metamorphosis.

8. A cement pond is preferable for the tadpole pond, and the pond wall slope should be gentle to provide habitat for the tadpoles.

II. Feed management

1. The breeding methods for frogs also differ at different stages. Only by adopting different breeding methods for different stages can the survival rate of the frogs be ensured.

2. In addition, feed should be given on a fixed schedule, in fixed amounts and at fixed locations. Generally, in spring and autumn it is given around midday, while in summer it is given in the evening or in the morning.

3. Frog feed is required to be fresh, clean and nutritious.

III. Frog breeding techniques

1. The key to frog breeding technology is artificial breeding, because wild field frogs often have a parasite called Diplostomulum sp. parasitizing in the frog's muscles. Generally, the method of artificial egg laying and isolating the adult frogs can effectively prevent this disease.

2. Frogs should be stocked at a density of about 1 group of breeding frogs per 3 sq m, and stocking should begin before May.

3. Breeding frogs are required to be large in size, and parent frogs that have been spawning for 1~2 years are best. The mixed stocking ratio of females to males is 3:1, and the stocking density is relatively lower than that of meat frogs.

4. It takes about three years from young frog to sexual maturity. The management of breeding frogs should strengthen the feeding of protein feed, mainly earthworms, supplemented by moth-attracting insects.

5. The normal balance value of the pond water should be maintained, and it is required to be fertile and lively. When the water temperature stabilizes at around 22°C, preparations for spawning and hatching should be made.

6. Female frogs weighing more than 50 grams can lay many eggs at one time. Generally, a male and female in amplexus lay eggs on aquatic plants.

7. Frog eggs are light yellow and round, and they attach in sheets to the gelatinous egg membrane floating on the aquatic plants, making them very easy to identify.
