1, breeding quail. On the land in the bullfrog pool, put cow dung, rotten fruit, washed rice water, etc., mix with the soil, and put it into a seedling to allow it to breed. After breeding for a period of time, the animals can be preyed by bullfrogs during the night. It is also possible to use sporadic wasteland, to use enough cow dung to cultivate earthworms, and produce 5-7 kg per m2.
2, light trapping. Above the frog pool food stand, 23 cm away from the surface of the water, a 30 watt black light or violet light is hung to attract insects, flying fleas, etc. At night, the bullfrogs will gather under the lights to prey. This method works best from May to September. Lights should be turned on after the sun goes down to the middle of the night, and there will be more dew on the second half of the night. There should be less insects and electricity should be turned off to save electricity.
3, cultured snails. The use of sporadic ditch ponds or construction of small pools can also be propagated and reared in the water of the frog ponds, producing a pink egg mass every 5 to 10 days during the high temperature season. Each egg mass has about 1000 eggs, and the eggs will be broken and hatched. Bullfrog feed.
4, sericulture. After using the mulberry sericulture in front of the house, the silkworm grows quickly. It takes only about 20 days in one's life. The young silkworm can be used to feed young frogs and grow to 4.5 to 5 years old, which can be used to feed frogs.
5. Feed Tenebrio. Tenebrio is the best feed for bullfrogs and is easy to feed. It can be fed only with wheat bran and cabbage leaves. However, worms grow slowly and must be expanded in order to ensure feed supply.
6, induced fly breeding. In the bullfrog breeding pond 30 cm above the place to hang a large basin, trays, etc., put decoy such as waste meat, fish viscera and other attracting fly breeding, when the fly larvae fall from the basin into the water, it has become a frog's cuisine. It is also possible to build a small pool, put rubbish in the pool, and then put rice into the water, etc., stamp it on the surface of the pool, and breed it for several days to feed the bullfrog.
7, training leeches. The leeches, commonly known as "red worms" and "fish worms", are ideal feeds for oystercatchers. First drain the water from the cultivation tank. After disinfection in the clearing pool, dry 1 kg of chicken manure and bean curd residue (or other livestock and poultry manure) in each square meter of the pool. It is best to spray water for 40 cm after exposure to sunlight for one week. And into the leeches provenance, a few days later the pool water turns green, and after two weeks the pool water will produce a large number of leeches.
8, the use of scraps. The slaughtered meat from the meat factories and restaurants shall be disinfected and rinsed, and mixed into the mixed feed. Where silk reeling plants are available, silkworm cocoons can be used as feed, and pig lungs and bovine lungs can be purchased and chopped and fed.
9, catch small fish shrimp. Located near rivers, lakes, or fish ponds, farms often catch wild fish and shrimp for feed.
