How to raise frogs in winter

The hibernating period of frogs is from November to March of the following year, and the hibernation cycle is about 100 days. According to the different sites of various farmers, there are several ways for frogs to spend the winter for novice frog farmers.

1. Overwintering with grass. At the beginning of hibernation, some aquatic plants, such as water peanuts, should be put into the pond, accounting for about 60% of the water surface of the frog pond, or the pond should be covered with straw 30 cm thick, which can prevent frost and ensure that frogs survive the winter.

2. The haystack overwinters. Pile a haystack in the leeward direction of the frog pond, or first spread loose soil 50-60 cm thick, pile grass on top, keep moist, and then cover with a layer of plastic film. When the temperature drops, frogs will hibernate by themselves into the haystack.

3. The greenhouse overwinters. In the frog pond 30 cm high from the water, with wood and bamboo or steel bar to build an arch or herringbone scaffolding, with plastic film cover sealing, it is best to cover a layer of net rope, anti-wind to break the film, so that the pool temperature is not lower than 10 ℃, to ensure that frogs survive the winter. When the temperature rises, it is necessary to properly uncover the film and ventilation to prevent frogs from dying of stifling heat and lack of oxygen.

4. The cave overwinters. In order to adapt to the latent habit of frogs digging holes, the pond soil can be loosened around the frog pond in advance, and several caves with a diameter of 10 cm and a depth of 1 m can be dug at the leeward of the sun to keep moist for frogs to hibernate.

5. Diving through the winter. Frog ponds to maintain a depth of 1-1.5 meters, the bottom to leave about 10 cm of silt, so that frogs dive into the mud to survive the winter. The hot spring overwinters. Where there are conditions, the use of hot spring water to keep frogs safe through the winter is the best. Generally, overwintering pools can be built on the spot near the hot spring exit, with a depth of 60-150 square meters and a water depth of 1-1.5 meters. Bamboo hedges or plastic nets should be used as anti-escape facilities, and anti-escape fences should be set up at the entrance and exit.

6. Earthen pot overwintering. Use two tile pots of the same size, the lower one put some wet soil, put the frog in, and the other cover it, then dig a 50-60 cm pit and bury the two covered pots to survive the winter safely.

7. Jars and cans survive the winter. The vats and pots are first filled with some soil and a little water to moist the high soil, a small amount of stagnant water in low-lying places, covered with water plants, and covered with grass curtains and other insulation materials around and above the vats and cans. Pay attention to breathability when using plastic film to keep heat. It can also be filled with boiled water in plastic buckets and placed in vats and cans to raise the temperature. The effect of overwintering with this method is very good, but it can only solve a small number of frogs overwintering.

Frog culture cycle

It is reported that it takes more than a month to go from egg to frog, and it takes two months to reach adulthood, which is related to environmental factors such as temperature. Frogs in nature generally have a life span of about 5 years, while farmed frogs can live for about 13 years. But all kinds of frogs have their own lifespans. Generally speaking, the bigger the frog, the longer the life span. Bullfrogs can live for 16 years.

The main points of raising frogs

I. Construction of frog ponds

The size of the frog pond can be flexibly controlled according to the actual situation. The frog pond is surrounded by a brick wall fence with a height of more than 1.5 meters to prevent frogs from escaping or being preyed on by snakes. It is best to build frog ponds near your home to facilitate management. Both ends of the frog pond shall be provided with water inlets and drains respectively, and sealed with iron sticks and close-eye nylon nets to prevent escape. Water plants and small shrubs should be planted around the frog pond to facilitate adult frogs to inhabit.

II. Nursing care of breeding frogs

Before the cold winter comes every year, the pool water should be drained, but it should always be kept moist so as to create favorable conditions for frogs to hibernate in mud holes.

Third, reproduce larvae (tadpoles)

After the sting season every spring, an appropriate amount of live water should be put into the frog pond to let the female frog breed tadpoles. After breeding tadpoles, frogs should be isolated to prevent them from swallowing tadpoles.

IV. feeding and management of tadpoles

1. Feed live feed. As small tadpoles feed on young animals, tadpoles such as water fleas, wigglers or other small frogs should be often put for their consumption. These young animals can generally be caught in paddy fields, ponds, dead ditches and other water.

2. Enough bait should be given. Because the small tadpoles will eat small and kill each other in the case of lack of food, so the bait should be sufficient, so that the small tadpoles have bait to eat at any time.

V. feeding and management of young and adult frogs

1. Graded feeding. Because of the fierce temperament of frogs, it is very common for big frogs to eat small frogs and other law of the jungle. In order to put an end to this phenomenon, frogs of the same size should be raised in stages, and frogs of the same size should be raised together. They should be fed enough bait so that they can all eat enough to avoid cannibalism.

2. Source of bait. Frogs eat a variety of foods, such as earthworms, insects, small fish, shrimp, crabs, snails, clams and so on. In order to ensure that the source of the bait can contact the vendors of water basin chickens and ducks in the nearby town market, give them an appropriate deposit and require them to collect and provide themselves with the chicken, duck crop and small intestines and lungs abandoned every day, and then cut it up as bait. You can also boil some tea bran and pour it into fertile soil such as banana roots, tree roots or garbage dumps. Soon, a lot of earthworms will be drilled out for people to catch as bait.

3. Feeding place. As frogs like to hunt in the water, do not like to hunt on land, so bait should be put into the surface of the pool to facilitate frogs to hunt.

4. Points for attention. The bottom of frog ponds should be covered with fertile soil tens of centimeters thick; the water of frog ponds should not be too deep, preferably 30-40 centimeters; fresh water should be infused frequently to discharge stale water; and human frog ponds polluted by pesticides, chemical fertilizers or industrial waste water should be strictly prevented.

We all know that many animals have the habit of hibernating in winter, their resistance will decline in winter, and the temperature is colder in winter, so they eat less, so they need to pay more attention to take care of them in winter.
