About the breeding method of bullfrog

First, the cultivation pond conditions Cultivation ponds generally use a small cement pool, water depth of 0.6-1 meters, an area of ​​8-10 square meters. The slope of the pool wall should be slightly larger, so that it is convenient for the frog to land on the pool wall after the rest and metamorphosis. Because the newly hatched carcass is only 5-6.3 mm in length, the swimming ability is poor. It is mainly due to suckers sucking attachments to rest. The water hyacinth, aquatic plants, and tree roots should be put in the pool, covering 1/3 of the total. The pool is surrounded with bamboo foil to prevent enemies and a bait station is set 10 cm below the surface of the pool.
Second, stocking density Newly hatched quail can be properly bred, easy to manage, can raise 2000-3000 cubs per square meter. After 10 days, as the individuals grow up, their feeding capacity increases, and the density should gradually decrease. Generally, 500 to 1,000 animals are stocked per square meter, and after 30 days, 100 to 300 animals are stocked per square meter before metamorphosis. When stocking, dip for 3 minutes with 3% salt and disinfect and sterilize.
Third, the amount of bait After hatching, the first 6 days, the quail mainly rely on the body to provide nutrition yolk sac, 6 days later disappeared with the yolk sac, began to eat plankton and artificial diet, fertilization before cultivation, nurturing plankton, to solve the opening bait , can increase survival rate. The artificial baits that are fed include snails, fish, animal organs, leeches, bean cakes, and rice bran. Feeding amount: 7-30 days old quail, every 1000 birds feed 40-70 grams per day, including animal foods accounted for 70%; 30 days after metamorphosis, every 1000 pupa feeding 60-80 grams per day, including Animal food accounts for 57%. Powdered feeds should be cooked and then fed into groups. Fish and fish intestines should be chopped and snails should be crushed and fed. Daily feeding time is 16-17 hours.
Fourth, the daily management and cultivation of the process of changing the water once every 3-5 days, each time 10-15 cm, each time when the water temperature change can not be over 3 °C, regular time every day to clean the food table. Since larvae have become young frogs after 80-110 days of cultivation, the mortality rate before the metamorphosis is higher. Therefore, it is necessary to strengthen management, stop feeding, keep the environment quiet, and strive to increase the survival rate of metamorphosis. Carnivorous fish, cockroach larvae, water snakes, tiger-spotted frog tadpoles, and dragon larvae will ingest bullfrog tadpoles. Once they are found, they must be promptly removed.
