Frog breeding techniques and site construction methods how much is it per mu for frog farming

Frogs have now become a favorite dish on the dinner table. The meat of frogs is very fresh and tender, and the practice of frogs is also very many, and the practice is also very simple. In addition, the nutritional value of frog meat is also very rich, so more and more people are joining the ranks of raising frogs in captivity. Today I'm going to talk to you about some of the breeding techniques of frogs.

Frog culture technology and site construction method

1. Frog culture 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.

2. The field large pool of 4 × 6 meters is a single pool, with cement on the wall and soil at the bottom, while the courtyard pool is generally 1 × 1.5 meters to 2 meters deep, with irrigation holes and drainage channels, with a water depth of 20 cm to 50 cm. The surface of the pool must be equipped with a shade board. Generally, 40 adult frogs can be raised per square meter.

3. Soil ponds, brick ponds and rice fields can be used in frog culture ponds, 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. 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 abnormal 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.

4. Metamorphosis management: frog eggs become young frogs about 70 days after hatching. During the period from the appearance of forelimbs to complete metamorphosis, tadpoles mainly rely on the absorption of tail supply, breathe air on their lungs, and begin to jump out of the water to land and perch. When more than 90% of tadpoles become young frogs, they can be reared in young frog ponds.

How much does it cost to raise frogs per mu?

The cost of frog farming is not high, and the input cost of raising frogs per mu in the past three years is about 10 to 15000 yuan. If you add some later feed, but also add some labor costs, so the investment per mu is about 20,000 to 30,000 yuan, but the profit of these frogs is very high.

What matters should be paid attention to in raising frogs?

1. Before making up our mind to breed frogs, flies, earthworms, Tenebrio Molitor and EM organisms, we should master all-round breeding techniques, such as frogs, flies, earthworms, Tenebrio Molitor, and so on. Technology is the core force of production and the basis of success. Without a good grasp of comprehensive frog breeding techniques, do not act blindly, for the loss will outweigh the gain. It is required that the water source is sufficient and pollution-free, the environment is quiet, and the ground is slightly higher and will not be flooded.

2. Frogs live on insects and mainly feed on active insects. In the case of artificial breeding of frogs, we should also begin to develop artificial breeding of some active insects, but the most convenient and quickest means is to breed maggots, earthworms, yellow powder insects, and so on. But before breeding, we must do a good job in bait production. There is a saying: before the arrival of soldiers and horses, food and grass go first.

3. After all the work is done, frog seeds should be prepared, and the frog breeding period is from March to June every year, so before spawning, frog seeds should be fully prepared to lay the foundation for high yield.

What are the common diseases of frogs?

1. Red leg disease, which is caused by virus. The muscles of the diseased frog's abdomen and legs showed punctate hyperemia, the muscles were red, the frog body was paralyzed and weak, dull, refused to eat, and died a few days later. Prevention and control methods: one is to pick up the diseased frog and soak it in 10%-15% salt water for 15 minutes, which can be cured after 2 days; the other is to move the frog into another pool and spray it with 1/10000 copper sulfate solution throughout the pool.

2. Swollen leg disease is caused by bacterial infection after leg injury. The leg edema of the diseased frog is like a tumor, which affects food intake, resulting in malnutrition and death of the frog. Prevention and treatment: soak the legs of diseased frogs in 30 mg / L potassium permanganate solution for 15 minutes; at the same time, feed tetracycline twice a day, half a tablet each time, for 3 days.

In the above article, we briefly introduce some feeding methods of frogs, in fact, the feeding methods of frogs are relatively simple compared with other animals. In fact, the construction method of frog farming taught to you today can also be adjusted according to your own land.
