A Detailed Guide to Wood Frog Market Prices and Farming Techniques
The wood frog, also known as the Chinese brown frog or "red-bellied sack," is a common frog found in damp ground. It combines medicinal, culinary and cosmetic uses and has high economic value. It is now farmed artificially in many regions, so how much does a wood frog cost per jin? What are the artificial farming techniques?
I. Introduction to the wood frog:
1. Is the wood frog a protected animal?
The wild wood frog is a national second-class protected animal and a provincial-level protected animal, so its trade is prohibited. Once more than 20 are illegally hunted, the relevant legal responsibility must be borne; in serious cases, the offender may be sentenced to fixed-term imprisonment of up to three years, criminal detention, control, or a fine. Most of those seen on the market are artificially farmed.
2. Where are wood frogs distributed?
Wood frogs are mostly distributed in damp places. Generally, during hibernation they mainly avoid the cold in relatively deep water; after winter passes, they leave the water and move into marshy land to grow. At present, they are relatively common in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Shaanxi, Shanxi, Gansu, Qinghai, Henan, Hebei, Shandong and other places in China.
II. How much does a wood frog cost per jin?
Wood frog market prices vary, generally around 100 to 200 per jin, but because of differences in variety, place of origin, sex and selling time, there will be certain price differences. For example, in the Changbai Mountain area, the market price of live female wood frogs in spring is about 100 to 150 per jin, and the market price of male wood frogs is about 20 to 35 per jin; in autumn, the market price of female wood frogs is about 150 to 240 per jin. In the Harbin area, live wood frogs sell for about 188 per jin; in the Jilin area, fresh Changbai Mountain wood frogs cost about 168 per jin; in the Mudanjiang area, fresh female wood frogs cost about 220 per jin. So the specific price still needs to be checked at the local market.
III. What are the artificial farming techniques for wood frogs?
1. Site selection and construction: what place is suitable for farming?
Wood frogs are suited to growing in a warm and cool environment with sufficient water, convenient drainage and no strong light. So when choosing a site, try to choose open ground with relatively convenient drainage for farming. After choosing the site, build a 1.5 m high protective net around it to prevent escape or attacks by birds. In addition, install a shade net on top, and dig several ponds inside, adding an appropriate amount of river water, well water or tap water for the wood frogs to hatch and lay eggs. Generally, adding water to about 40 cm in the pond is best.
2. Seed selection and stocking: what kind of frog seedlings are good to choose?
Every April, select some frog seedlings that are strong, plump, undamaged in appearance and active in jumping, and stock them into the pond. Generally, stocking 2000 per sq m is sufficient.
3. Management techniques: how to manage?
(1) Feeding requirements: wood frogs do not have high food requirements. Generally, young frogs use small insects, yellow mealworms, mosquitoes and flies, maggots and so on as food. After growing for a certain time, they will eat some rice bran, rice husks, corn and so on. So during farming, feed must be reasonably matched, and each feeding must be at a fixed time, in a fixed amount and at a fixed place to ensure uniform growth.
(2) Water quality requirements: during farming, the water quality must be kept clear, the water changed in time, and the pond disinfected regularly to avoid disease.
(3) Water temperature requirements: under normal circumstances, wood frogs grow well at around 23 degrees. If it is higher than 32 degrees or lower than 14 degrees, it will affect the growth of wood frogs, so the temperature must be checked daily, and ventilation and shading measures must be taken to prevent adverse reactions in the wood frogs. In winter, the water temperature must be kept below 4 degrees, and the water depth must not exceed 1.5 m. Some branches or straw should also be placed in the overwintering pond to help the wood frogs hibernate safely.
(4) Humidity requirements: wood frogs have a strong ability to retain moisture. Generally, during the metamorphosis stage of young frogs, growth is best when humidity is kept at 88%; within two months, young frogs grow best at 81% humidity; after growing for more than two months, humidity is best controlled at around 75%. So humidity must be kept normal. Generally, in high-temperature weather, humidify twice a day, and at other times adjust humidity according to weather changes.
(5) Timely shading and rain protection: wood frogs should not be exposed to direct sun, so in the hot summer season, appropriate shading is needed to prevent dehydration and a reduction in the skin's protective ability. In addition, a rain shelter should be built to prevent the wood frogs from getting rained on in order to cool down, which could lead to death.
The above is a detailed introduction to wood frog market prices and artificial farming techniques. We hope it is helpful to everyone.
