Bullfrog breeding conditions what are the risks of bullfrog breeding

Bullfrog is a kind of amphibian, which is quite common in daily life. It is named bullfrog because its cry is very similar to that of cattle. Moreover, bullfrog is a large edible frog, which not only has certain edible value, but also can be used as medicine. It can be described as a wide range of uses. So do you know what requirements are required to raise bullfrogs? Is it risky to raise bullfrogs?

Bullfrog culture conditions

Bullfrog pond culture requires adequate water source, convenient drainage and irrigation, no pollution, quiet environment, convenient transportation, adequate power supply, usually one large pond for every 100 square meters, and each large pond is divided into four small ponds on average. The edge of the pool is surrounded by 40-mesh sieve silk, which is about 1 meter higher than the bottom of the pool, and the bottom of the sieve silk is 20-30 cm buried in the soil. The ridge of the pool is 40 cm high, the slope ratio of the pool is 1:3, the water level is 30-40 cm, and the depth of the water body is not less than 20 cm. The inlet and drain are arranged at the opposite corner of the big pool. Each pool puts four 80 cm × 40 cm foam plates as the bullfrog's rest table and uses a black sunshade net to shade the sun.

What are the risks of bullfrog farming?

1. The sales market is not taken into account, and the finished product is unsalable due to high output and low local sales. After cultivation, our county now has a relatively low yield of 5000 jin per mu, which can reach 1500 tons.

2. The culture technology failed, the culture density was high, the case fatality rate was high, and some of them were wiped out. For example, a farm in Lanxi Town was closed in the first half of the year.

3. The culture is not standard. In order to achieve high yield, antibiotics and other additives are continuously used in the culture process, resulting in product quality and safety.

4. Bullfrog farming is a high pollution industry, and its harmless treatment capacity has not kept up with it. If it causes serious environmental pollution, it will be forced to close the farm by the relevant departments.

5. it is difficult to restore farmland by polluting farmland. In the farmland where bullfrogs have been cultivated for 3 to 5 years, the soil salinity is high and it is not easy to resume ploughing. Although raising bullfrogs can make fishermen rich, the risks brought by raising bullfrogs should not be underestimated. I hope farmers will think twice.

Prospect of bullfrog culture

The medicinal use of bullfrog breeding prospect: the frog meat is flat, the taste is sweet, and the gallbladder is cold. It has the effect of promoting blood circulation and eliminating accumulation, relieving heat and detoxification, tonifying deficiency and relieving cough to treat a variety of diseases, such as edema, throat erosion and so on.

The fur of bullfrog breeding prospect: the leather of bullfrog is thick, soft, smooth, elastic, and has colorful patterns, which can be used as a high-quality raw material for leather products such as wallets and gloves. Shoes made of frog skin cost 400 yuan a pair. Frog skin is extracted and processed into leather glue, which is used as an adhesive for jewelry, diamonds and other ornaments.

The prospect of bullfrog breeding as feed: the by-product (head, viscera) of bullfrog is dried to feed chickens, which can increase the laying rate.

The foreground of bullfrog breeding is good at catching insects: bullfrogs, like other frogs, feed on agricultural pests. On average, a bullfrog can prey on more than 10,000 pests a year. A tadpole eats at most more than 100 wigglers a day.

The prospect of bullfrog breeding in aerospace: frog oil is used in the aerospace industry.

Culture techniques of bullfrog

1. Seedling stocking: bullfrogs are disinfected with 50 kilograms of quicklime or 10 kilograms of bleach powder per mu before stocking, and can be released 10 days after clearing the pond. Young frogs are soaked with 20 mg / L potassium permanganate solution for 10 minutes before stocking, 60 per square meter for young frogs and 30 per square meter for adult frogs.

2. Pool inspection: patrol the pond once a day in the morning, in the middle and in the evening to prevent bullfrogs from escaping. The running water is guaranteed 24 hours a day, and the daily water exchange rate reaches 300%. The water level can be controlled by the rise and fall of plastic intubation at the outlet. The water depth of the pond is generally 30cm to 40cm. Measures were taken in time to find abnormal food intake and activities of bullfrogs.

3. Feed feeding: the feed is mainly floating formula feed. Soak the formula feed with water half an hour before feeding to promote softening and expansion. The daily feeding amount is 7%-15% of the total number of frogs in the pond, and timely adjusted according to the climate, water quality and residual bait. It is appropriate to finish the feeding within half an hour. Bullfrogs should be raised by grades, and the individuals with larger sizes should be graded and screened in time, and the bullfrogs with similar specifications should be adjusted to the same pond for breeding.

4. Disease prevention and control: before stocking, bullfrog seedlings are disinfected with quicklime or bleach powder to kill enemy organisms and pathogens, and regularly sprinkled with bleach or strong chloroform in the whole pond. After dividing the pond, the frog body was disinfected with 20 mg / L potassium permanganate solution to prevent mechanical damage. It was found that diseased frogs and dead frogs were picked out and raised in isolation in time, and disinfected with high concentration of bleach or potassium permanganate solution.

As mentioned above, there are certain risks in starting a business, and no project can make a profit without losing money, so starting a business needs to be cautious and should not blindly follow the trend. At present, bullfrog farming has a very good prospect, but after all, it is a business, and it needs to be thoughtful in all aspects.
