Earth Pond Culture American Frog Technology
The American frog is a kind of large-scale edible meat frog that has been introduced in recent years in China. It has an annual output of more than 1,500 kilograms of frogs per acre and a net income of 20,000 to 30,000 yuan. Due to the conventional cement pool breeding method, the investment in infrastructure has limited the development of rural frog farming. The simple farming techniques in earthen ponds are easy to master and are very suitable for the majority of farmers. The advantages of the terrarium breeding frog: 1 breeding equipment investment is about 200 yuan per acre, less than 10% of the cement pool; 2 breeding sites are flexible, as long as it is pollution-free ponds, dams, ditches, rice fields with water sources, free space can be; 3 The conditions of earthen ponds are similar to those of American frogs. The oxygen content in the water is high, and the natural food is abundant. The frog grows more than 10% faster than the cement pool. In particular, maggots are robust, with few occurrences, and the survival rate is increased by more than 20%. 4 The earthen ponds can not only cultivate high-quality frogs, but also raise frogs (spawning, hatching, and breeding crickets).
The feeding technology of frogs in earthen ponds is basically the same as that in conventional cement ponds, but the construction of aquaculture ponds is different. Now it is introduced as follows.
I. Construction of a commodity frog pond
(a) The location of the aquaculture pond should have water, no pollution, and a quiet environment.
(2) To build pools in paddy fields or on idle grounds, 1 Calculate 1000 square meters of culture pond (1.5 mu), 600-700 square meters of pool should be dug, the depth of the pool is about 1 meter, and the slope of the pool is 1:3. The frog went ashore; 2 remaining 300-400 square meters of fruit trees, vegetables or any of its long grass, resulting in a shaded environment for frogs to rest and feed; 3 around the aquaculture pond with a width of 1.5 meters wide nylon cloth or plastic screens Well, buried 20 centimeters below the ground to prevent frogs from fleeing and rat snakes from entering the invading frogs. After the pool is repaired, 150 kg of lime are disinfected per 1000 m2, and water frogs can be released after 5 days.
If ponds, dams, and ditches are used to raise frogs, there is no need to dig pools separately. As long as they do a good job of anti-escape facilities, empty areas are left next to the pools to remove debris from the pool and eradicate rat snakes. After disinfection, the frogs can be reared.
Second, if the number of breeding frogs is large, commercial frog breeding can be used.
If the number is small, it is advisable to raise frogs per square meter and construct a frog pond. The minimum size should be no less than 10 square meters. Build a pool with the same product frog pool. During the breeding season, the frogs are spawned in breeding ponds. Due to the large number of frogs and their frequent activities, it is easy to hit the egg blocks deeper into the bottom of the water and cause hypoxia. Therefore, it is necessary to continue to withdraw the pool several times a day to find the eggs and immediately pick them up and put them in the incubator. Third, frog eggs hatch
Cage hatching. Use a nylon cloth to grow a ship-shaped cage that is 2 meters wide and 1 meter wide, and put it into a commercial frog pool. The cage is filled with 30 to 40 centimeters of water, and it is fixed with bamboo rafts. The roof of the box is covered with bamboo or straw curtains to prevent sun exposure and rain. The tanks were filled with floating plants, and the collected eggs were placed in water grasses for hatching. About 6000 eggs can be laid per square meter, and 1 to 2 nests of eggs are placed in each box on the same day. In the 2 to 3 days at the appropriate temperature, hatchlings can be hatched. The hatching rate is as high as 80% to 90%.
IV. Cultivation
Freshly hatched cockroaches can be kept in hatchery cages or moved into cocoon-cultivated cages (cage practices should be kept in the same incubator). The water depth of the cage is required to be more than 50 cm to facilitate the movement of the cage. Each cage is equipped with 1 to 2 feeding bowls. The pots should be submerged into water for 10 cm to facilitate feeding. He just hatched 4 to 5 days of nutrition by oocysts, do not need to eat, later fed cooked egg yolk. Use 1/3 of the egg yolk to make a slurry into the food bowl of the cage for every 10,000 eggs and allow it to feed twice daily. 10 days old quail can be fed raw milk, bean dregs, pig blood and other foods, can also be fed artificial compound feed. As we grow up, we should gradually bin and reduce the density of the Baotou. The frog can be placed in a frog pond for feeding after it has been grown for 1 to 2 months. Every 700 square meters of water can be stocked 15,000, until the product frog.
