Key points of Frog Culture techniques

1. Successful cases of frog breeding

At the end of 2014, Wang Anwei and other three people jointly invested 150000 yuan to set up frog farms, leased 7 mu of paddy fields, dug ditches, weaved purse seine, and introduced three species of black spot frog, golden frog and tiger frog. After more than 3 months of feeding, the total number of adult frogs reached 550000, the production of frogs per mu was more than 1300 kg, the income per mu was about 50, 000 yuan, and the total yield reached 350000 yuan. At the same time, 150kg of Loach is raised in ditches per mu of rice, with an income of 3000 yuan, and more than 700kg of pollution-free rice per mu with an income of more than 2000 yuan.

II. Model benefit analysis

With the use of 1 mu of paddy field, after a little reconstruction, frog breeding was carried out to estimate the breeding benefit of frogs.

1. Input

Total: 13800 yuan. Among them: (1) the land lease cost is 800 yuan; (2) the frog farm construction cost is 2000 yuan (including 1000 yuan for materials and 1000 yuan for labor); (3) the frog seedling fee is 5000 yuan; (4) the feed fee is 6000 yuan.

two。 Output

General per mu yield of adult frogs 1000-1500 kg, according to the lowest 1000 kg calculation, winter market per jin of finished frog wholesale price of more than 20 yuan, you can get an income of 40000 yuan.

3. Profit

40000 yuan-13800 yuan = 26200 yuan

III. Culture techniques

1. Key points of breeding techniques of young frogs

The juvenile frog pond is kept at a depth of 0.3-0.5 meters, and 3-5 feed tables and rest tables are set on the surface of the water. The stocking density of newly metamorphosed young frogs is 200kg / kg, and the stocking density of young frogs less than 50g is 100g / kg. The young frogs in the same pond should be adapted to the caliber of the young frogs after being raised for a period of time. The newly abnormal young frogs were fed with juvenile frog feed with a particle size of 2.0 mm, 3.0 mm at 20g and 30g, and 3.5 mm at 50g. The daily feeding amount is about 5% of the total body weight of the frog, once in the morning and afternoon. Water should be changed regularly to keep the water fresh.

two。 Key points of adult frog culture techniques after young frogs are transferred into adult frog ponds, the food intake of young frogs is large, and the growth rate is accelerated, which is an important period for the formation of commercial output, and the supply of adequate bait is the most important, mainly artificial feed, and timely separate breeding. Adjust the feeding density. After one month of feeding, when the body weight of adult frogs reached 100 grams, the feeding density was 30 per square meter, and changed to 10 eggs per square meter 2 months later. After short-term breeding, it can become a commercial frog on the market. Fourth, the main points of disease prevention and control of frogs should be prevention. In the process of breeding, as long as we pay attention to environmental hygiene, ensure fresh feed, balanced nutrition and scientific feeding, the occurrence of frog diseases can be reduced. The common diseases of frogs are fulminant septicaemia, bubble disease, rotifer disease, red leg disease, gastroenteritis and so on.
