How much is the price of 2019 forest frogs per jin? What is the method of building the spawning pool of Rana chensinensis?

Rana chensinensis belongs to amphibian anura frog family, frog genus, commonly known as frog, is a kind of precious amphibian with high economic value, which integrates food, medicine and supplement. The following is a description of the price of Rana chensinensis how much money a catty and the Chinese frog spawning pool construction method.

It is distributed in 18 provinces in China, most in Northeast China, mainly in Changbai Mountain and Xiaoxing 'anling area. Jilin Province is one of the important producing areas of Rana chensinensis. The main medicinal part of Rana chensinensis is the oviduct thousand products of female individuals, namely Rana chensinensis oil, which has the effects of nourishing essence, nourishing yin, moistening lung, nourishing brain and improving intelligence. Therefore, Rana chensinensis has important economic value. In recent years, because of the serious destruction of ecological environment and excessive capture, wild resources are rapidly reduced. In order to meet the market demand, it is imperative to develop artificial breeding of Rana chensinensis.

How much is the price of a catty?

The origin, size, season and sex of forest frog are different, and the price is also different. The live forest frog on this side of Changbai Mountain costs 100-150 yuan a catty for female forest frog in spring, 20-35 yuan a catty for male forest frog and 150-240 yuan a catty for female forest frog in autumn. The above prices come from the soil flow network fruit and vegetable market channel.

Spawning pool of Rana chensinensis

Chinese frog oviposition method cent circle type oviposition method and cage type oviposition method two kinds. The temperature in spring in Northeast China is relatively low, but the spawning period of Rana chensinensis is generally around Qingming, the temperature is required to be 5~7C, the lowest water temperature is 2 C, and the spawning pool is 3mx4m, and the pool depth is 40cm. Only in this way can it conform to the habit of laying eggs in shallow water. The cage spawning method should be adopted for Rana chensinensis to lay eggs in the overwintering pool, that is, the overwintering pool can be used to lay eggs in the overwintering pool after modification. The specific methods are as follows: first, discharging some water in the wintering pool, reserving the pool water with the depth of 1.0 - 1.5m, making a spawning box with the mesh size of 0.5cmx0.5cm into 60cmx70cmx50cm, putting the spawning box into the spawning pool, connecting a mineral water bottle in the air above the spawning box, increasing buoyancy to make the spawning box float on the water surface, putting 30 - 50 pairs of frog seeds into the spawning box according to a plan, after the Chinese frog lays eggs, moving the frog egg mass out of the spawning box, sending the frog eggs into the hatching pool for hatching, At the same time, Rana chensinensis is put into the reproductive dormancy field for postnatal dormancy for 10 - 15 days, and then the next batch of Rana chensinensis is put into the spawning box for holding and spawning. The advantages of this operation are that it is not necessary to construct the frog spawning pool, which can save the site and water source, and because the water depth in the pool is more than 1m, it can also avoid cold damage to the frog.
