Special breeds: Rana sylvatica
The Chinese name is Rana chensinensis, also known as the ferret, and the Hashi (Hashikase).
Changbai Mountain's original ecological Chinese Rana sylvatica is a specialty of the northeastern part of the Changbai Mountain range in northeastern China. Pure wild animals are also known as Hashi (Ha Shichao). It is completely different from the original pheasant. Only our country is listed as a vulnerable (v) species. It is a rare amphibious animal that combines medicinal, food supplement and beauty functions. Changbai Mountain's original ecological Rana chensinensis has been valued by people for its unique medicinal value and nutritional value, and has become the highest economic value among frogs. Among the forest frogs produced in various places, the forest frogs grown in Changbai Mountain have become the best in the forest frog for their large size, high oil production rate, strong system, and high reproduction rate. China's Rana sylvatica is rich in 4 hormones, 9 vitamins, 13 trace elements and 18 amino acids. It has a high value in medicinal use, nourishing and cosmetology.
The original ecology of Changbai Mountain China Rana sylvatica is delicate, easily digested and absorbed by the human body. It is suitable for people of all ages, particularly for the sick and sick and the elderly, and has a high tonic value. When cooking, it releases a large amount of nitrogen-containing extracts such as lysins and amino acids, which makes them rich in flavor. Because of its delicious taste and rich nutrition, Rana chensinensis has become a tribute in the Ming and Qing dynasties. It has been classified as the “Bazhen†(specialty, wing, bone, belly, wormwood, palm, pupa and gluten) and the “four treasures†of the court. "(The bear's paw, Hashung, Dragon, Hericium) and the "New Northeast Sambo" (Hashi, Rhodiola, not old grass). The Chinese Rana sylvatica is a living ginseng of Changbai Mountain wild ginseng.
Rana sylvatica is fully farmed and the investment in the year is effective. It is suitable for our forest frog production areas, rural areas, and townships to promote. It is also a good project for the development of courtyard economy. It also has less investment, quick effect, no risk, and high efficiency. It is suitable for families and factories. Aquaculture.
A family farmer needs to catch or buy 200 pairs of frogs (two or three years old frogs) when they are harvested at the end of the first year of harvest, and use water tanks or cellars. The pool naturally overwinters. When the eggs are laid in the spring of the second year, the frog eggs are pure and of good quality, and the breeding frog is still a commercial frog. (Frog eggs can also be collected in early spring). At the same time buy Rana sylvatica feed Tenebrio species 25 kilograms, the system for the use of insects with 200 wooden trays, in the 8-10 square meters of indoor breeding, wheat bran for insect repellent can be used with the purchase. According to different seasons, the cost of keeping insects is also not one, about 4-6 yuan per kg of breeding costs. In addition to wheat bran, cabbage, radish, potatoes, and other vegetable feeding insects are also prepared. When the climate is warm in the coming spring, the area of ​​insects will be increased and the scale of insects will be increased.
The farms can be built in the first year of fall or in the early spring next year. 200 frogs are required to build a 1,000-square-meter site surrounded by double-layered plastic sheeting. If you have the ability to invest, you can also build semi-enclosed or fully enclosed shark farms, with large investments and good results. At the same time, hatching ponds and metamorphosis ponds were constructed with plastic cloth in the venue. Materials used for construction include plastics, stakes and iron wire. There are irrigation and micro-spray facilities on the site. A water pump and a hose. Dozens of micro-spray nozzles. A corresponding number of black light lamps are set up on the site. In June, July and August of insect activity, a large number of flying insects can be recruited every night to supplement the forest frogs and save part of the mealworms.
With the above conditions, a small frog farm is completed, and it is carefully reared according to the farming techniques. In the autumn, 150,000 frogs can be harvested. If sold, on average, each can sell 0.20 yuan, 30,000 yuan. Of course, it is the most cost-effective way to sell your own frogs over the winter. You can sell frogs in the second year, and there are about 40,000 females. Combined RMB 120,000.
According to the above a small farm we can calculate. 200 pairs of species of frogs will be combined for 800 yuan, 25 kilograms of species of insects will be combined for 1,000 yuan, 200 pieces of wooden plates will be worth 800 yuan, and insects will have about 2,000 yuan for wheat bran, and construction sites will use 1,500 yuan (including irrigation equipment and black light). Individuals can operate reptiles feeding frogs. Working hours are calculated at 3,000 yuan. A total of about 10,000 yuan is spent. The sale of small frogs will earn 30,000 yuan and the investment will be 10,000 yuan. We can get 20,000 yuan in income. According to local management experience, if the management is carefully and carefully managed, the above indicators are fully achievable.
