What do you know about frog breeding pond construction technology?

Frog ponds are divided into spawning ponds, tadpole ponds, and frog ponds. It is usually advisable to choose a place that is both humid and warm and sheltered from the sun, such as a long cement pool or an earthen pond. The wild pond is 4 6 meters for a single pool, it is best to smear cement, and the bottom of the pool is still muddy; The small pond in the courtyard is generally 1 to 2 meters.

The depth of the pool is generally 1 meter, with irrigation holes and drainage pipes, and the water depth is 20 to 50 cm. The surface of the pool must be provided with a sun visor. On average, 40 adult frogs can be raised per square meter.

Frog ponds are cultivated in earthen ponds, brick ponds, rice fields, etc., and the key is to prevent escape. If possible, you can build a wall, or you can use a net fence, generally 1 meter high. The water depth in the pond is 30 60 cm, and the water surface ** or the sunny side is piled up into a mound for land frogs to inhabit, accounting for about one-third of the entire pond.

Grass or crops are planted on the pasture. Throw a small amount of floating grass into the pond water. As a pond for tadpole breeding, only a small amount of land area is reserved for the ecological habitat of young frogs.

The tadpole pond uses a cement pool, and the slope of the pool wall should be gentle, so that the tadpoles can rest. <>

Frog selection: Frog selection is healthy, non-mutilated, and non-diseased individuals, female frogs are larger, male frogs are larger, and the vocal sacs on both sides of the neck will expand when they chirp. Breeding frog stocking:

Breeding frogs are stocked in September and October, with a density of 10 12 square meters and a male-to-female ratio of 1:1. Hug to spawn:

The average temperature of the breeding frog is 16 20 o'clock, and the egg-laying time is generally 5 6 o'clock in the morning and 11 o'clock at noon. Egg retrieval: The fertilized eggs of the frog are collected and incubated in the sterilized ring groove, and the darker side of the egg mass is used as the animal pole, which must be facing upwards, and the whiter side is the plant pole, which must be facing downward.

Infrastructure: frog breeding is mainly based on earthen ponds, one acre of rice fields can be transformed into three breeding ponds of about 200 square meters, the cost of pond renovation is about 1,000 yuan, and the food table, bird prevention net, etc. are about 300 yuan. Introduction Fee:

Artificially bred frogs need to be introduced from formal breeding units, and they also need to improve the breeding procedures, and the current introduction cost is about 3,000 yuan per mu. Feed cost: raising a pound of frogs needs yuan, feed cost is directly related to the survival rate, yield, etc., with an average of 2,500 pounds per mu ** calculation, feed cost needs 12,500 yuan.

For the construction technology of frog breeding ponds, first of all, it is necessary to pay attention to the cleanliness and sanitation of the breeding area, and also to do a good job of related disinfection, and at the same time, it is also necessary to regularly replace water resources, pay attention to the growth of frogs in time, and also need to pay attention to the appropriate size and appropriate depth.

Site selection, construction, habitat. The construction of frog breeding ponds, it is generally advisable to choose a place that is both humid and warm and sheltered from the sun, with a long cement pond or an earthen pond, the pool depth is generally 1 meter, with irrigation holes and drainage channels, the water depth is 20 50 cm, and the water depth in the pool is 30 60 cm. The water** or sunny side is piled up to form a mound for the frog's land habitat, and grass or crops are planted on the mound.

The construction technology of the frog breeding pond is exquisite, the size and depth of the pond have accurate numbers, and it is necessary to dig trenches for drainage, which can be equipped with PVC plastic pipes.

Under normal circumstances, it is cultivated in some wilds, and it is necessary to ensure that the area is particularly wide, and it is cultivated in a deep pit, which can add some aquatic plants, and then wrap it with red bricks outside, which will not collapse, and is also suitable for its growth, which will make its growth rate become particularly fast.

The technology of building this breeding pond should be to dig a pit directly in the pond, and then it does not need to be particularly deep, but if it is a little larger, it is very easy to raise, and it is just at the bottom of the time to put an anti-**, so that you can avoid the frog from escaping. Also pay attention to the density of the culture.

It is necessary to choose a suitable environment, and to pay attention to the living habits of frogs, the size of the pond, the choice of shape, and the depth of the problem.

There must be a high wall around the frog pond, which should be designed as a rectangle, and there should be water inlet and outlet settings on both sides of the frog pond, and anti-escape measures should also be taken to prevent frogs from escaping. There should also be some dirt in the frog pond, because frogs are amphibians. When the temperature is relatively high, frogs can take refuge in the dirt.

You can also grow some rice in the frog pond. This will not only increase food crops, but also provide sun protection for frogs.

1. Temperature: The appropriate temperature for frog growth is 20 30, when the temperature drops below 10, the feeding and activity gradually weaken, when it drops below 5, it begins to hibernate when it drops below 5, the activity weakens significantly when the water temperature exceeds 32, and the frog will die one after another when the temperature exceeds 35.

2. Humidity: Frogs do not have a tissue structure that protects the evaporation of water in the body, and it is obviously not enough to maintain the humidity of the body surface by relying only on the mucus secreted by the gland, so the habitat environment should not only have a pond with water, but also a warm and humid environment overgrown with weeds.

3. Light: Frogs are nocturnal, afraid of direct sunlight, but tend to weak light, light has a promoting effect on frog body metabolism, growth, and reproduction, such as long-term life in the dark its gonads are difficult to develop and mature, and even stop laying eggs and sperm.

4. Water quality: frog tadpoles require frog pond waters to have a higher amount of dissolved oxygen, generally required to meet fishery water quality standards, although adult frogs and young frogs breathe with lungs, but the dissolved oxygen in the water is still high and has a good effect on it, pH is appropriate at 7 8, and the general salinity is not higher than 2.

How to achieve artificial breeding of frogs? What are the key points of frog farming? There are many people who are afraid of frogs, and there are also many people who like to eat frogs because they are tender and not high in fat.

The artificial breeding technology of frogs is introduced as follows: How to breed frogs? Frog artificial breeding technology 1. Pond construction Frog breeding ponds are divided into hatchery ponds and breeding ponds.

1.The construction of the hatching pond is set according to the number of tadpoles hatched, and the size of the hatching pond is usually required to be more than 1 acre. The water body is too small, and the water quality is not easy to stabilize.

2.The construction of the breeding pond The size of the breeding pond is generally 200 square meters, east and west, and each pond should be equipped with drainage pipes in the town. The pond is 40 50 cm high, and there is a ring ditch in the middle of the pond, which is about 60 cm wide and 40 cm deep, and a tidal flat 3 5 m wide is set aside in the middle for frogs to come ashore and rest in summer.

How are frogs farmed? Frog artificial breeding technology Arrange shade nets above the tidal flats, about 80 cm of high mountain potatoes, or plant and sow rice, mainly used for summer shading and high temperature. Each frog pond is divided by a mesh of more than 40 meshes, and is about 1 meter high.

At the same time, the whole farm uses purse seine nets to erect net sheds and carry out closed coverings to prevent birds from preying on frogs. 2. Incubation method The frog breeding time is generally concentrated in March to April. Egg masses are collected early in the morning and should be collected 2 to 3 hours after spawning.

At this time, the egg membrane outside the fertilized egg has fully absorbed water and expanded, and the zygote can be transposed in the egg membrane, so that the animal pole of the fertilized egg is facing upwards and the plant pole is facing down (the fertilized egg animal pole is black-brown facing upwards, and the plant is extremely milky white or pale yellow, facing downwards). Be careful not to flip the egg mass at will to avoid the inversion of the plant and animal poles of the fertilized egg. How are frogs farmed?

Frog artificial breeding technology cages can be placed in the hatchery tank for incubation, and the cage material is nylon net of more than 100 mesh. When erecting the cage, the top and bottom of the cage are fixed and only rough, so as to avoid the wind blowing and causing the cage to shake, and the draft is about 50 cm. A plastic box is placed in the middle of the cage to hold the egg masses.

Usually 5 10 egg masses are placed in a plastic box, each egg mass is about 2000 eggs. If there is no sufficient hatchery pond, the egg masses can also be moved directly to the adult frog breeding tank, and the stocking density at this time is generally one egg mass per square meter. The water level of the breeding pond should be kept at the highest level.

The egg mass is placed in a plastic frame while the plastic basket is secured in the annular sulcus. The above is all about the artificial breeding technology of frogs, if you are also interested, you can master the breeding technology first!
