General situation, benefit and Prospect of Chinese Forest Frog Culture

(1) Overview of aquaculture

The local names of Chinese forest frogs are Hashi frog, frog, oil toad, etc., which belong to amphibia, Anura, frog family and frog in zoology. Chinese forest frog is a subspecies, which is classified as Changbai Mountain subspecies of Chinese forest frog in the northeast of China. Chinese forest frog is one of the animals with high economic value, and it is a precious frog species with both edible and medicinal use. with the increasing demand for food, medicine, nourishment and health care, forest frog and its products are in short supply year by year, and their prices are increasing year by year. With the development of market economy, the natural resources of forest frogs are increasingly exhausted, and the quality of frogs decreases obviously. In order to protect and cultivate wild resources, ensure the sustainable development of forest frog industry and meet people's material needs to the maximum extent, the artificial breeding industry of Chinese forest frog developed rapidly. In the early 1980s, people began to explore the technology of closing ditches and raising frogs, and continuously achieved scientific research results and successfully popularized them, fundamentally solving the problem of excessive capture and destruction of natural resources. At present, it has become a rich industry for people in some mountainous areas of our country, and some important breakthroughs have been made in the research on artificial breeding technology of forest frog.

General situation, benefit and Prospect of Chinese Forest Frog Culture

The techniques of closing ditches to raise frogs and semi-artificial frogs have now spread all over the distribution areas of Chinese forest frogs. According to recent statistics, there are more than 9000 frog breeding sites in Liaoning Province, more than 8000 in Jilin Province, and more than 2000 in Heilongjiang, with a total area of more than 20 million hectares. The benefits of other areas are also increasing rapidly. With the continuous improvement of semi-artificial breeding technology, Liaoning Province has formulated local standards, rules and methods, and the deep processing and marketing of forest frog products have greatly promoted the development of forest frog breeding industry.

The research on artificial breeding technology of Rana chensinensis accords with the theory of ecological economics and the modern forestry management idea of three-dimensional development and utilization of forest resources. the techniques of simulating the ecological environment under the forest, artificial bait insects, defending natural enemies, safe overwintering and rapid breeding of frogs, female mutagenesis and the construction of fencing mode are successful, and the related technical problems of artificial frog breeding have been preliminarily solved. At present, this technology has been extended to Liaoning, Jilin, Heilongjiang, Qinghai, Gansu, Sichuan, Hubei and other places.

(2) benefits of culture

1. Ecological benefits: Chinese forest frogs live in the forest for six months a year, mainly feeding on insects, and most of them are pests, such as beetles, night moth larvae, ulna, etc., and can also feed on disease-transmitting animals and intermediate hosts of parasites, such as mosquitoes, flies, slugs and so on. Forest frog plays an important role in maintaining forest ecological balance and biodiversity.

2. Social benefits: due to the development of forest frog breeding industry, many farmers have reliable projects to get rich, and the scientific and cultural level of many farmers has been greatly improved. Forest frogs and their products have come to the table and enriched people's structure of life. to provide people with nutrition and health care and skin care beauty products.

3. Economic benefit: the medicinal use of toad has a long history. Oviductus Ranae has the effect of "tonifying kidney essence, nourishing yin and moistening lung". It is often used for diseases such as physical weakness, post-illness disorder, lethargy, palpitation and insomnia, night sweats and hemoptysis. It can improve people's memory and sexual function and promote people's growth and development, so forest frog oil is used as the main material to make advanced nourishing and skin care products. The chemical composition of Oviductus Ranae is complex, of which protein accounts for 56.3% of the total, as well as brevisol, saccharides, phospholipids, vitamins, fatty acids, amino acids and trace elements and a variety of hormones. Therefore, in addition to people's fresh food, forest frog is also one of the main species of export to earn foreign exchange. The price of each female frog is 8 yuan, and the price of each kilogram of Oviductus Ranae is 2000 RMB2,600. Some frog farmers have an annual income of more than 50-600000 yuan.

(3) the prospect of culture

At present, the Chinese forest frog and its products sell well in domestic and foreign markets, and the supply has been in short supply. From the development trend, due to the improvement of people's living standards and changes in food structure, game food with high protein and low fat is more and more favored by people. The natural resources of forest frogs have been greatly damaged. According to people's awareness of environmental protection, it is impossible to restore resources and meet market demand. Only by taking the way of artificial breeding to realize industrialization, can we broaden the breeding field and improve the economic benefits of the breeding industry, help farmers shake off poverty and become rich, increase economic income, and meet people's needs for forest frogs and products at the same time. Due to the late development of the forest frog breeding industry, the low level of technology and the imbalance of breeding benefits, most of the available resources are still barren and the production is small, so it is difficult to supply the market in large quantities. Therefore, there is great potential for the development of forest frog breeding industry, and it has been supported and supported by governments at all levels. Therefore, artificial raising of frogs has a bright prospect.
