How to raise Rana chensinensis

When it comes to forest frog, I believe everyone is familiar with it, because forest frog is a famous medicinal economic frog species in our country. Forest frog not only has high medicinal value and can be used as a valuable traditional Chinese medicine, but also has high edible value. It has the effect of moistening lung and nourishing yin, invigorating brain and intelligence. So do you know how to raise forest frogs? Next, let's learn about it with the editor.

How to raise forest frog

After about 50 days of feeding, tadpoles become young frogs, land on shore, and become young frogs after eating insects, mosquitoes, yellow powder insects, maggots and so on. As long as the temperature is right, the frogs begin to catch insects. They are fed with small yellow powder worms or maggots every day, and the worms are scattered directly on the ground around the frog farm. In actual breeding, breeding yellow powder worms or fly maggots are generally used to feed young frogs and adult frogs, and yellow powder worms are bred with rice husks. Maggots can use 1 part of pig, cow, sheep blood (any kind) to add a small amount of rice husk or corn flour to outdoor vats, pots, cement ponds and soil ponds, and 3rel 5 days to naturally produce a large number of maggots, this method is simple and fast, fast, large quantity.

Culture technology of forest frog

First of all, every spring (April) put enough frog eggs or leave enough frog seeds, the density of frog eggs in the hatchery should not be too high, no more than 2000 eggs per square meter. During the incubation period of frog eggs, attention should be paid to fresh water quality, timely change of water, scientific feeding, timely prevention of frog disease, quietly poisonous clam in the hatching pond, and timely introduction to the forest after worm metamorphosis. Although the young frog does not live in the water, it must live on the temperate land. When the humidity is insufficient, it is necessary to replenish the temperature in time to keep the temperature above 70%, so as to ensure that the forest frog can breathe normally. To this end, sprinkler irrigation facilities can be set up in the frog field, sprinkler irrigation or artificial rainfall can be carried out during dry days, or sprinkler can be used to spray water.

In winter, when the forest frog returns to the pond for the winter, the temperature of the pool water should be kept below 4 ℃, and the water depth should not be less than 1.5m, so as to prevent the surface of the water from being freeze-dried. Some straw scales and branches are put into the overwintering pond to facilitate the hibernation of forest frogs.

The other is hibernation in the kiln. Overwintering soil damage can be built outdoors or indoors. The earth kiln is 2 meters wide and 2 meters deep, and its length depends on the number of forest frogs. At the bottom of the damage, put some stones, tile heads, branches, straw Xuan, as a hibernation shelter for forest frogs. Anti-rodent equipment should be installed to prevent rats from harming the overwintering forest frog. Put 1 foot thick river sand in the kiln and spray it with moisture. Forest frogs must pay attention to moisturizing during the overwintering, so that the skin of the frog body is moist, breathing is normal, and prevent carbon dioxide poisoning in the body.

Matters needing attention in forest frog culture

Enter the adaptation period of stings. In the early stage of formal overwintering, the climate is unstable at the end of autumn and the beginning of winter. during this period, Chinese forest frog needs an adaptive process to change from lung respiration to skin respiration. Affected by climate change, the forest frog constantly adjusts its physiological function. When the temperature decreases, the forest frog enters the water, and when the temperature rises, the forest frog comes out of the water, so many times, and finally gradually adapt to all skin breathing, thus entering the overwintering period. If the forest frog is forced into the water to survive the winter, it is very difficult for the forest frog to adapt to the change of its physiological function and will inevitably die of asphyxiation.

The period of adaptation to the sting. This is the adaptation process of forest frog from breaking dormancy to living on land. With the rise of the temperature in spring, the temperature difference between day and night is large, when the forest frog comes out of the sting, it is necessary to adapt to the temperature change and find a hidden cover at low temperature.

The living habits of forest frog

The life habit of forest frog is different from that of other frogs, and its annual life cycle can be divided into two different stages: aquatic life and terrestrial life. The aquatic life period is to enter the hibernation state hidden in the deeper water body in order to avoid the cold winter and spend the dormancy period. During this period, the forest frog does not eat, the activity stops, and the metabolic activity in the body drops to the lowest level. After the end of the water life period, the forest frog leaves the overwintering water body and completes its reproductive activities in the swamp area. After a short reproductive dormancy in the soil around the spawning ground or under the litter, it enters the forest and begins its terrestrial life. This is the most active time of the year. Forest frogs eat a lot of food to meet their needs for growth and development. At the same time, make material reserves for hibernation and reproduction in the coming spring.

Forest frogs are distributed in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Qinghai, Gansu, Shaanxi, Shanxi, Hebei, Henan, Shandong and other places.

As the benefits of forest frogs are known, more and more people begin to catch wild forest frogs for profit, resulting in fewer and fewer forest frogs, and even facing the danger of extinction. And the breeding of forest frogs is also gradually becoming more and more, which is a promising breeding project.
