CATDOLL : CATDOLL: During the frog breeding process, how should the frog farm be constructed?

1. During the frog breeding process, how should the frog farm be constructed?

1. Spawning Pond

The spawning pond is the place where adult female frogs mate and lay eggs after coming out of hibernation every spring. Since the temperature is low when the forest frogs come out of hibernation, and the forest frogs have the habit of reproductive dormancy after laying eggs, the spawning pond must be located on the side of the river, close to the hibernation pond, in a sunny and flat area. The specifications of the pond are: 5 meters x 20 meters, the bank is 60 to 80 centimeters, the width is 50 centimeters, the water depth is 30 to 50 centimeters, and 500 pairs of breeding frogs can be placed. The frog farm can build multiple spawning ponds according to its own scale needs.

2. Hatching pool

The hatching pond is where frog eggs are hatched into tadpoles. The pond should be built in a sunny and transparent place. The bottom of the hatching pond is required to have a certain slope, with one side deep and the other side shallow. The water depth is about 40 cm and the shallow water is about 10 cm. The water temperature is adjusted by different water depths. The general specifications of the pond are 4 meters x 6 meters. The bank of the pond is generally wide at the bottom and narrow at the top, with a bottom width of about 50 cm and a bank width of about 30 cm. The inlet and outlet are both located on one side, and a wire mesh should be installed at the outlet to prevent tadpoles from escaping. Multiple hatching ponds can be built according to needs. The reference standard is: 500,000 tadpoles can be hatched per 100 square meters of hatching pond.

3. Tadpole breeding pool and metamorphosis pool

The rearing and metamorphosis pool is where tadpoles grow and metamorphose. The pool is generally 4 meters by 5 meters, with a water depth of 30 to 40 centimeters. A circular safety pit about 40 centimeters deep is built in the middle to prevent the death of a large number of tadpoles due to drought or water shortage. To facilitate the replacement of pool water, the inlet and outlet can be set diagonally, and wire mesh is required to prevent tadpoles from swimming downstream or upstream and getting lost.

4. Wintering Pond

Wintering ponds are where forest frogs hibernate. Some natural pools, reservoirs or larger mountain streams or rivers are natural wintering ponds for forest frogs. In order to ensure the safety of forest frogs overwintering, frog farms should build one or more wintering ponds according to needs. The specifications are 20 meters × 40 meters, which can be used as a wintering place for 50,000 adult frogs or 300,000 young frogs. The size of the wintering pond can be determined according to the amount of breeding. The depth of the wintering pond should be about 2.5 meters, and the water depth under the ice should be kept at about 1 meter in winter. A layer of broad-leaved leaves about 5 cm thick is laid on the bottom of the pond to serve as a hibernation shelter. Building a dam in the deep water of the river in the breeding farm to keep the water level at about 2 meters can also be used as a hibernation pond for forest frogs.

5. Fence

There are many ways to build a fence, such as the wall method, trench method and plastic sheet fence method, etc. However, the most convenient, economical and currently widely used method is the plastic sheet fence method.

Build a breeding site. The wood frog likes to live in a moist and cool environment without strong light. It has no special requirements for the breeding environment. You can use an idle open space to build a breeding site. It is best to build a breeding site in an area with high terrain, clean water sources, and convenient drainage. River water, well water, and tap water can also be used. When building, use a film, mesh, or trimmed wall to enclose the breeding site into an escape-proof net with a height of about 1.5 meters. You must also make a bird-proof net, and take shade and sun protection measures on the top. You can plant some trees or plants in the site to provide shade and moisture.

It is necessary to build spawning pools, hatching pools, tadpole rearing pools and metamorphosis pools, wintering pools and fences.

The forest frog farm is mainly divided into two large pools. One is the spawning pool, which is mainly used for laying eggs during the spawning period of forest frogs. The other is the hatching pool, which is used to hatch tadpoles for easy protection. Adult frogs can roam freely.

2. What is needed for the breeding environment of forest frogs?

For example, if you contract a stream or river that flows all year round, the living conditions required by the wood frog are very high. Clear stream water with a depth of 50 cm is enough. They are basically not found in large rivers and lakes. Areas with serious water pollution are not suitable for the growth of wood frogs. In recent years, wood frogs have been cultivated within the scope of industrial breeding, which means that artificially bred wood frogs can continue to be cultivated.

But it is not allowed to catch wild forest frogs, after all, the number of Northeast forest frogs is relatively scarce. Of course, the nutritional value of Northeast forest frogs is very rich and is very popular in the market, especially for Japan and South Korea. To provide shade for forest frogs, some small ponds need to be dug in the breeding farm for rest and laying eggs, and the water level of the hatching pond must be kept above 40 cm, so that they can have an active habitat. After the tadpoles hatch, they can become young frogs when they grow to 50 days. Artificial breeding is possible.

The oil is mainly used for medicinal purposes, and the meat can be eaten, but the forest frog has very high requirements for the growth environment. The country has unified regulations for forest frog breeding. It is necessary to apply for site acceptance, and transportation and sale must have relevant approval documents. Failure to apply for approval is illegal. Some people are selling forest frogs online, which is hotly discussed online as indiscriminate hunting of wild forest frogs to destroy the ecological balance. This has attracted the attention and exposure of CCTV's related programs, which directly led to the local comprehensive closure of ditches and the prohibition of forest frog breeding, causing great economic losses to the majority of breeders.

This means that as a key protected animal, before breeding, you must first go to the local relevant departments to apply for a domestication license, and obtain a business processing license and a transportation permit before you can sell and transport the forest frog. The breeding site for forest frogs requires sufficient water and is conducive to the wintering of forest frogs. During the breeding process, it is necessary to ensure that the virus fed to forest frogs does not break out. Some medical experts point to the source of the virus as caused by humans eating wild animals. For the sake of human health and safety, the Wildlife Protection Law has been studied to prohibit the trading and eating of wild animals and increase the protection of wild animals. my country's largest artificial forest frog breeding base, Northeast Artificial Forest.

The breeding of forest frogs requires complete sunshade and rain shelter facilities to prevent the growth of forest frogs from being affected by direct sunlight or rain. The temperature suitable for the growth of forest frogs is about 23.1℃. The humidity in the farm is adjusted according to the different growth stages of forest frogs. Ventilations are set in the farm to keep the air fresh, stagnant water is cleaned up in time, and the breeding site is disinfected regularly to prevent rodent, bird and snake damage.

In mountainous forest areas, frog farms must be located in a humid climate and close to nature. The requirements are stricter than those for semi-human breeding. There must be a multi-layered shade environment such as ponds, grasslands, bushes and trees in the same place.

3. What are the requirements for temperature and humidity for breeding wild forest frogs?

In the northeast, the wood frog hibernates for more than five months. During the long hibernation period, the wood frog body gradually transforms and stores the nutrients stored in the autumn in the hair follicles, providing nutrition for the development of frog eggs and the initial growth of tadpoles. Of course, in some areas with lower temperatures, the excess temperature under the ice is about 1~3 degrees, and one or more solar ponds must be built upstream of the breeding farm to make the river pass through the solar lake to increase the temperature before entering the breeding pond. Dry lakes are also built according to the terrain, with a water depth of 0.3-0.4m. Depending on the conditions, the area must be large or small to provide enough water for the breeding lake.

Returning to wild forest frog breeding, what are the requirements for temperature and humidity?

From the oviposition position to metamorphosis, the life process can occur from the melting of ice and snow to 28 degrees Celsius, MAS 28. In the soil growth stage, the average annual precipitation is 600~1300 mm, the average temperature is 3.5%C~4.C, the relative humidity under the summer forest exceeds 80%, the ground temperature cannot exceed 32℃, and the relative humidity of the ground is best maintained at 85% to 95%.

Frog farms usually choose high mountains on both sides and a valley in the middle, which is what farmers call "two mountains and one ditch". The soil for frog breeding is different from that of semi-artificial frog farms. It usually combines the spawning, hatching and reproduction of forest sea buckthorn tadpoles, and is a three-purpose pool with a small area and high storage density. The pools that need to be built have high standards, are connected in rows, and are easy to manage, and one is an earth lagoon.

The breeding farm and the forest frog breeding farm are surrounded. The permanent fence must be made of strong and durable materials such as brick walls, cement boards, rare earth boards and asbestos tiles. The wall base of the fence should be leveled first. The wall base should be more than two inches deep. The connection of the sealing board should be tightly hinged and the height should be 60-80cm. The top should be provided with a 90-degree curved angle edge with a length of 10 inches. An anti-electric mouse device should be placed outside the wall, and the electric iron FIO should be removed from the electric wall and the iron wall respectively. Water source is another important condition for selecting a frog breeding farm. There should be enough water in the dry season, that is, the breeding farm has one or more small mountain rivers that are not dry in summer and have a large flow in winter. The stream is based on sand or mud, and the water volume should not be too large or too small,

The temperature requirement is very high, it must be around 25 degrees. If it is lower than 20 degrees, it is very easy to get burned. The humidity requirement is also relatively high. If the humidity is particularly low, the frogs are very easy to be dried to death, so you must control the temperature and humidity when planting frogs.

The requirements for humidity are also relatively strict. It is necessary to ensure that the daily lighting time is not less than two hours, and the humidity should be maintained at 60%. The water quality must be particularly clear, and the water should be changed frequently to facilitate growth and laying eggs.

It has very high requirements for temperature and humidity, otherwise it will cause certain impacts and many problems. Try to control the temperature at around 20℃. At the same time, you should also prepare more food. The food should be rich in nutrition and have more varieties.

The temperature and humidity should not be too high or too low. Try to choose moderate conditions, and be sure to pay attention to disinfection and sterilization. You should also pay attention to the nutritional value of the feed when feeding.
