Bullfrog food
1, bullfrogs belong to the carnivorous animals, a wide range of food, including annelids, arthropods, mollusks, fish, amphibians, reptiles and mammals. It is reported that bullfrogs mainly devour animal pests of crops (82% in number) and also devour a small number of beneficial animals (5.2%).
2. Bullfrogs also swallow some plant food, mostly leaf debris, flowers and plant seeds.
3, the bullfrog is very voracious and has a large amount of food, it is observed that a bullfrog has to swallow 43.7 grams of food in one night, the amount of food swallowed by the bullfrog is related to the temperature change, the water temperature is 21-30 ℃ when the food is the most, the food is at least 20-14 ℃ when the food is least, and the food stops below 14 ℃.
4, the bullfrog's hunger tolerance is also extremely strong, generally can be tolerated for 4 months to a year.
What do bullfrogs eat?
Bullfrogs have a wide range of food, but animal food is the mainstay, and their diet differs during the tadpole period from the adult frog stage.
1, tadpole period is omnivorous, not strict on food requirements, almost all plankton in the water can be ingested, but also can ingest the general feed fish feed, especially addicted to eat boiled egg yolks, raw fish, liver, fly maggots, and boiled potatoes, sweet potatoes, rice bran, peanut meal, etc., and the rest, such as bean curd, fruit peel, etc., can be used as bait.
2, adult frogs love to eat active bait, trapping insects, crustaceans, small fish and shrimp, snails, worms, spiders, cicadas, locusts, crickets, termites, maggots, earthworms, and fish eggs and waterfowl chicks, and so on, must be tamed in artificial breeding.
3. In addition, bullfrogs occasionally have the habit of eating big and small.
Bullfrog animal feed culture
1, breeding earthworms: in the bullfrog pond land, put cow dung, rotten fruit, rice-washing water, etc., and soil mixing, put into the seed earthworms, so that their breeding. After a period of breeding, earthworms can be eaten by bullfrogs in the evening when they come out of the earth. You can also use sporadic barren land, the application of sufficient cow dung to cultivate earthworms, each square meter can produce adult earthworms 5 to 7 kilograms.
2. Lighting insect attraction: in the frog pool above the food table, 23 cm from the water surface, hanging 30-watt black light or purple light, can attract insects, ticks, etc., and bullfrogs will gather at night under the light to feed. This method has the best effect in May to September, the light should be turned on after the sun goes down to the first half of the night, the second half of the night, more dew, fewer insects, you should turn off the light to save electricity.
3, breeding Fukushou snail: the use of sporadic ditch ponds or build small pools, but also in the frog pond water reproduction, breeding, in the high temperature season, every 5 to 10 days to produce a peach-colored egg mass, each egg mass has about 1,000 eggs, eggs rupture hatch small snails will be used as bullfrog feed.
4, sericulture: the use of front and back of the house mulberry silkworms, silkworms grow fast, a lifetime of only 20 days or so, the young silkworms can be used to feed the young frogs, up to 4.5 to 5 years old, can be used to feed the adult frogs.
5, feeding yellow mealworm: yellow mealworm is the best feed for bullfrogs, easy to feed, only need wheat bran and green vegetable leaves can be fed. However, the growth of worms is slow, and it is necessary to expand the feeding quantity to ensure the feed supply.
6, fly maggots: in the bullfrog breeding pool above the 30 cm hanging pots, trays, etc., inside the bait, such as waste meat, fish offal, etc., fly maggots, when the maggots climbed away from the mouth of the pot fell into the water, it will be the frog's delicacy. Can also build a small pool, in the pool into the tofu residue, and then put into the rice water, etc., in the pool surface cover, after a number of days maggots into, can be fed to bullfrogs.
7, cultivate water flea: water flea is commonly known as "red worm", "fish worm", is the ideal feed for tadpoles. First of all, the water in the culture pool is drained, after cleaning and disinfecting the pool, each square meter of the pool is sprinkled with dry chicken manure, tofu dregs, etc. 1 kg (or other livestock and poultry fertilizers), preferably after a week of exposure to sunlight, 40 cm of water, and put into the water flea seed source, a few days after the pool water becomes green, two weeks later, the pool can be reproduced in the pool water with a large number of water fleas.
8, the use of scraps: meat factory, restaurant slaughter scraps disinfected clean, pounded fine, mixed with mixed feed feeding. Reeling factory places, available silkworm pupae as feed, but also can buy pig lungs, cow lungs, chopped feeding.
9, catch small fish and shrimp: located in the river, lake or fish ponds near the breeding sites, you can often catch wild fish, shrimp for feed.
