CATDOLL : CATDOLL: How to make Rana?

We are all familiar with the forest frog, because it is a very common frog meat food in the market, and it has very high nutritional value, it can nourish the brain and moisten the lungs, and it has a very good therapeutic effect for some people with long-term coughs. It is a kind of food that can be eaten and used as a health product, but the market demand for them is very strong, so many people have begun to artificially breed forest frogs, but there will be many problems in the breeding process, so how do we breed forest frogs? Let's take a look at it together.

The forest frog is also a frog species with high medicinal value. Because of their very high value, they are captured in large numbers by people, causing their numbers to gradually decrease. If we want to raise forest frogs well, the first thing we have to do is to choose a breeding site. Forest frogs do not like strong light. They like some humid and cool environments, and they do not have particularly high requirements for breeding farms. We can use some idle land to build forest frog breeding grounds.

It is best to choose places with higher terrain and convenient water sources, clean drainage and irrigation. We can also use some river water or well water to arrange a breeding farm ourselves. When building it, we can use mesh or fence to make an escape net. The height must be kept above one and a half meters. We also need to make some bird-proof nets to prevent frogs from escaping and prevent their natural enemies from appearing and causing damage to the frogs. There must be shade and sun protection measures on the top.

We can put a layer of plastic film on it, or plant some trees and plants in the grassland to provide shade for the forest frogs. Such an environment is almost suitable for the growth of forest frogs. We also need to dig some small ponds in the farm for them to rest and lay eggs, and the water level of the hatching pond must be kept above 40 cm. This can provide them with an active habitat. After the tadpoles hatch, they can become young frogs when they grow to 50 days.

At this time, they will come ashore to feed, mainly small insects, so the feed at this time is mainly some mealworms, mosquitoes, flies and small insects. When the temperature is right, they will find food by themselves. We can sprinkle some insect feed evenly on the ground to allow them to grow quickly. We must also provide enough feed and nutrients. We can raise mealworms ourselves or introduce some mealworms.

However, the breeding cost may increase when we purchase it. Generally, we will cultivate it by ourselves. The breeding of mealworms is very simple. You can mix wheat bran and bean cakes or corn together and feed them to forest frogs. In this way, they can grow quickly. This method is very convenient and fast, and forest frogs also like to eat it very much. They must be hatched in April every year. We need to put an appropriate amount of frog eggs in the farm and pay attention to the breeding density. It should not exceed 2,500 per square meter.

When the frog eggs are hatching, we must pay attention to the freshness of the water, change the water in time, pay attention to the hygiene of the environment, and disinfect the pond in time. When we disinfect, we can use quicklime powder to sprinkle the entire pond, but we must pay attention to the amount. If it is too much, it may also cause damage to the frogs. Start hatching ten days after disinfection to avoid poisoning and death of the young frogs. When the young frogs are growing up, we must introduce them to the farm in time for breeding.

When raising frogs, we must pay attention to the temperature and humidity of the breeding pond. We must ensure high temperature and increase the indoor temperature to achieve a cooling effect. We must keep the humidity above 62% to allow the forest frog to move and breathe normally. In the farm, we can install spraying facilities so that the pond can be humidified at any time.

In fact, forest frogs have very strong immunity and they generally do not get sick, so we only need to feed them some antibiotics and nutrients on time to make them grow quickly. However, once sick forest frogs are found, they must be isolated in time, the cause must be found out and the right medicine must be given, and then check whether other forest frogs in the pond are infected with the disease.

Once a disease occurs, it must be treated in time. Only after the sick forest frog has completely recovered can it be put into the pond for breeding. The above is an introduction to the technology of forest frog breeding. I hope the above content can help you. In fact, as long as we raise forest frogs well, we can sell them at a very high price in the market and make a lot of money. I hope the above knowledge can help you. If you want to know more about frog breeding, please continue to follow us.

The forest frog, also known as the snow frog, is widely distributed in northern China and is also distributed in Siberia and North Korea. The forest frog is a completely different animal from toads and frogs. The forest frog has a flat head, slender limbs, and a body length of 70 to 80 mm. The tympanic membrane is round, with triangular black-brown spots on the tympanic membrane. The back of the body is mostly khaki, and there are usually dark spots scattered on the warts. The dorsal fold bends obliquely outward above the tympanic membrane. The forest frog is mainly terrestrial, often living in a moist and cool environment without strong light. It mainly inhabits still water bodies such as mountains, forests, swamps, ponds, puddles and ditches and their vicinity, mostly in forest grasslands. The forest frog is agile and has strong jumping ability. It mainly feeds on a variety of insects, such as flies and mosquitoes [4].

Main types

Northeast Forest Rana

The Northeast Forest Frog is a frog species endemic to the mountainous areas of Northeast China. It is currently farmed in an ecological manner (semi-artificially) and is managed by the fishery authorities as aquatic animals[5-6]. It is the only species in my country where it is listed as a species of least concern (LC)[7].

Rana chinensis

The Northeast Forest Rana was formerly known as the Chinese Forest Rana. Now the Chinese Forest Rana is a separate species.

Chinese forest frog (scientific name: Rana chensinensis): Female frogs are 44-53 mm long, male frogs are smaller; the head is relatively flat, with equal length and width or slightly wider; the tip of the snout is blunt and slightly protrudes from the lower jaw, and the snout ridge is obvious; the nostrils are located between the snout and the eyes, and the distance between the noses is greater than the distance between the eyes and is as wide as the upper eyelid. The dorsal folds are zigzag above the eardrum; the length of the hind limbs is about 185% of the body length, and the tibiotarsal joints exceed the eyes or nostrils when the hind limbs are extended forward and close to the body; the space between the three outer toes is almost 2/3 webbed; there are triangular black spots on the eardrum. The distance between the inner and lower sides of the two large nuptial pads at the base of the first finger of the male frog is obvious, and the one near the wrist is not larger than the one near the finger; there is a pair of inner vocal sacs under the pharynx.

Distributed in Hebei, Beijing, Tianjin, Shandong (Qingdao, Yantai), Henan (Tongbai, Kaifeng, Dabie Mountains), Shanxi, Inner Mongolia, Ningxia, Gansu, Sichuan, Chongqing, Hubei, Anhui (Huoshan), and Jiangsu in China.[1]

Heilongjiang forest frog

The body length of Heilongjiang forest frog is 120-180mm. The head is relatively flat, and the length and width of the head are almost equal. The tip of the snout is blunt and slightly pointed, protruding from the lower lip, and the snout ridge is obvious. There are two small groups of vomerine teeth, which are oval. The rear end of the tongue is notched deeply. The eardrum is round. The skin is relatively rough. The dorsal fold is folded in the forehead, slanting outward above the eardrum, and there are flat warts on the back of the abdomen and the ventral surface of the posterior thigh. The back and sides of the male frog are gray-brown with a slight green tint, and there are also brown-gray or brown-black. The female is reddish brown or brown-yellow. There are triangular black spots on the eardrum. There are bright red and gray spots on the pharynx, chest and abdomen. The ventral surface of the limbs is gray, with red spots. The front of the tibiotarsal joint reaches the shoulder, and the left and right heels overlap slightly. The skin is relatively rough, and the back of the body and hind limbs and the posterior abdomen are densely covered with large round warts. The dorsal folds form a zigzag shape in the temporal folds, first connected to the temporal folds, and then reach the crotch. Body color varies: males are brown, brown-gray, or brown-black, while females are brown-red or brown-yellow, with a light-colored, wider ridge running down the center of their back.[8]
