Construction of Frog Culture Pond

To cultivate frogs, first of all, it is necessary to build a culture pond, and it is also the first step of culture. It still has some attention to the construction of frog culture ponds, not just casually. Its pond depth, water depth and pool surface all have a standard, and only by meeting these standards can we better adapt to the growth of frogs.

Construction of Frog Culture Pond

Frog ponds are divided into spawning ponds, tadpole ponds and adult frog ponds. Generally, it is appropriate to choose places that are both wet and warm from the sun, with long cement ponds or soil ponds as appropriate. The field large pool is 4 × 6 meters as a single pool, the wall of the pool is better smeared with cement, and the bottom of the pool is still muddy; the courtyard pool is generally 1 × 1.5 meters to 2 meters.

The pool is generally 1 meter deep, with irrigation holes and drainage channels, with a water depth of 20 to 50 centimeters. The surface of the pool must be equipped with a shade board. Generally, 40 adult frogs can be raised per square meter. Frog culture ponds can be used in soil ponds, brick ponds and rice fields, and the key is to prevent escape. If you have the conditions, you can build a brick fence or a net, which is generally 1 to 1.2 meters high.

The water depth in the pond is 30cm to 60cm, and the middle or sunny side of the water is piled into a mound for frogs to live on land, accounting for about 1x3 of the total pollution. Grow grass or crops on the mound. Put a small amount of floating aquatic plants into the pool water. The pond used to breed tadpoles leaves only a small amount of land area for the young frogs to land. The cement pond is better for the tadpole pond, and the slope of the pool wall should be gentle to inhabit the tadpoles.

Breeding techniques of Frog

1. Frog selection: breed frogs should choose strong, disability-free and disease-free ones for seeding. Usually, the female frog is larger than the male frog, and the external vocal sac on both sides of the neck of the male frog expands when he cries.

2. Breeder frog stocking: breeder frogs are released from September to October with a density of 10: 12 per square meter, with a female-to-male ratio of 1:1. Breeder frogs begin to hold pairs to lay eggs before and after Ching Ming Festival hibernates in frog ponds.

3. Cuddle to spawn: breeder frogs begin to cuddle freely when the average temperature reaches 16-20 ℃. After 3-4 days, they will lay eggs, usually at 5: 6 a.m. and 11:00 to 1: 00 p.m.

4. Egg block harvesting: the frog fertilized eggs are collected and put into the sterilized aquaculture pond to hatch. The darker side of the egg block is the animal pole, which must be upward, and the white side is the plant pole, which must be downward.

Can frog farming really make money?

1. Infrastructure: frog culture ponds are mainly soil ponds, and one mu of rice fields can be transformed into three ponds with an area of about 200m2. The main cost of pond transformation is 1000 yuan, and the cost of eating platform and bird prevention net is about 300 yuan.

2. Introduction cost: artificial breeding frogs (black spot frog) need to be introduced from regular breeding units, and they also need to improve the breeding procedures. At present, the introduction cost per mu is about 3000 yuan.

3. Feed cost: the feed cost needed to raise a jin of frogs is 4.5 to 5 yuan. The feed cost is directly related to the survival rate and yield. According to the average yield of 2500 jin per mu, the feed cost needs 12500 yuan.

4. Disease prevention: any living body may get sick, and the cleanliness and hygiene of the breeding environment is very important. Artificially farmed frogs need regular disinfection, prevention of enteritis, etc., and need to prepare about 300 yuan of preventive drugs.

5. Breeding profit: the total cost of raising one mu of frogs is about 20000 yuan, and the output of 2500 jin of frogs can be calculated according to the current wholesale market price of 20 yuan per jin, which can be sold at 50000 yuan, with a net income of 30000 yuan per mu.

The growth process of frogs

1. Frog eggs: the breeding time of frogs is about the middle to late April every year. In the process of reproduction, the female frogs hold each other, the female frogs ovulate, and at the same time, the male frogs ovulate, and the sperm and eggs are fertilized in the water, which avoids the time difference and greatly improves the fertilization rate.

2. Tadpoles: tadpoles are a primary stage of the ontogeny of amphibians. The early tadpoles are round or oval in shape and resemble fish in shape. They are nourished by the remaining yolk in the body. When the tadpoles mature, they begin to degenerate and gradually grow limbs.

3. Young frogs: tadpoles grow limbs after abnormal development, and their tails are absorbed and live ashore. Due to changes in physiology and environment, their vitality is very weak and their ability to adapt to the environment is poor, such as dry environment, hot sun exposure, heavy rain and so on.

4. Adult frogs: after a series of growth, young frogs grow into frogs, and their bare skin can not effectively prevent the evaporation of water in the body, so they can not live without water or humid environment for life, and are afraid of drought and cold, so most of them live in tropical and temperate rainy areas.

Although the construction of aquaculture ponds is the first step to success, it is also necessary for breeders to understand the living habits of frogs. Only by understanding the growth habits of frogs and their growth process can they be easily raised. In order to reduce unnecessary economic losses and obtain greater profit space.
