A new method for breeding and management of bullfrogs in vegetable greenhouses

Bullfrogs are hypothermic animals and have 3 to 4 months of hibernation each year. Bullfrogs can be farmed in vegetable greenhouses.
The suitable area for vegetable greenhouses is 1 to 2 mu. Ordinary arched greenhouses are long in the east-west direction and covered with double-layer non-drip plastic film. The sheds are planted with celery and there is a well (tap water is also available). Using straw or straw to make grasshoppers, the grasshoppers are placed on top of the shed at 4 pm every day, and set off at 9 a.m. the next morning to allow sunlight to pass through the greenhouse. The grass picks up the insulation effect, and when it is cloudy, the grasshopper does not have to be rolled up to prevent the temperature in the shed from falling.
The area of ​​the frog pool construction pro-frog pool is 20 square meters, located in the center of the greenhouse, the pool depth of 1.5 meters, slope of 1:2.5, the pool of transplanted water peanuts, water hyacinth, 20 days before the frog stocking with 2010-6 bleaching pond disinfection. The hatching pool is located next to the spawning pond, with an area of ​​4 square meters and a depth of 0.6 meters.
Frog frog stocking In the commodity frogs, bullfrogs with a body weight of about 500 grams, a frog age of two years or more, and a sexual maturity are selected as the pro-frogs, and 10 groups per acre are stocked, and the ratio of male to female is 1:1. When the temperature is between 15°C and 18°C, the frogs will be placed in a prepared greenhouse.
After bait feeding in March, the temperature and water temperature in the greenhouse are relatively high. The bullfrog eats vigorously and feeds it twice a day, mainly in the form of extruded pellets, together with animal feed such as small-sized fish, silkworm cocoons and cockroaches. The feed is put on the feed plate, and it is advisable to feed the food with a little surplus on the day.
After the daily management of frogs entering the greenhouse, in addition to the normal management of vegetables, new water is often added to keep the water fresh. Adhere to the patrol pool every day, make a good record of the various environments of the culture ponds, and periodically disinfect the frog pond with lime water of a concentration of 1010-6.
