CATDOLL : CATDOLL: Is frog farming profitable?

The most direct and important reason for breeding forest frogs is to obtain economic benefits. Forest frog oil is not only an important medicinal material for nourishing the kidney and essence, nourishing yin and moistening the lungs, but also a natural high-grade tonic with high nutritional value and health care functions. With the improvement of people's living standards and the change of nutritional concepts, humans attach great importance to seeking healthy and longevity drugs and health foods. The market demand for forest frog oil in my country and Southeast Asia is relatively large.

The Rana oil produced by the Changbai Mountain subspecies of Chinese forest frog has the best quality. "Jilin Changbai Mountain Chinese forest frog oil" has been approved by the state as a geographical indication product (GB/T19507-2008, implemented on November 1, 2008). The Changbai Mountain subspecies of Chinese forest frog is suitable for living in broad-leaved forests and mixed coniferous and broad-leaved forests with mountain streams and rivers in forest areas. It is mainly distributed in Jilin, Liaoning, Heilongjiang and other places, especially in the Changbai Mountain area, with reserves accounting for more than 90% of the country.

Affected by human activities, the environment suitable for the survival of Chinese frogs is deteriorating. The frogs grown under natural conditions cannot meet people's needs. Coupled with the indiscriminate hunting and killing by humans, the resources of wild Chinese frogs are becoming less and less, and they are even facing the risk of extinction. At present, commercial Chinese frog oil is still mainly wild resources, but the resources of wild Chinese frogs are limited. Chinese frogs and Chinese frog oil are becoming increasingly scarce, resulting in rising prices of Chinese frog products, which are difficult to meet market demand. Chinese frog products have always been in short supply in the domestic and foreign markets. There are many areas in Northeast China with large forest areas, many rivers, abundant water resources, good vegetation, and forest, temperature, humidity and other conditions suitable for the growth of Chinese frogs. The conditions for raising Chinese frogs are excellent, with great production potential and broad development prospects.

Although the demand for forest frog products in domestic and foreign markets is increasing, the supply and demand situation in the market will not change fundamentally due to the limited geographical location of the production area, and the market space for Chinese forest frogs and their products will only grow. Protecting forest frog animal resources and carrying out artificial and semi-artificial breeding of forest frogs is also one of the important measures to develop ecological agriculture and produce green food.

The closed ditch breeding technology of forest frogs is relatively mature, but the recapture rate of forest frogs in the production process is very low. The artificial captive breeding method requires large investment and high cost, and the breeding technology needs to be further improved. Semi-closed and semi-open breeding methods are currently the main methods of forest frog breeding.

Of course, like other industries, forest frog farming has its ups and downs. Before farming forest frogs, you must first learn farming techniques, do a good job of market research, find farming varieties and farming models suitable for the local environment based on your own conditions, and carry out forest frog farming in accordance with local conditions to reduce or avoid economic losses caused by farming failures.

Key points of captive forest frog technology Chinese forest frog is a precious frog species that combines food, medicine and tonic. It is welcomed by consumers because of its unique medicinal and nutritional value. With the continuous increase in market demand and the depletion of natural resources, the recapture rate of semi-artificially cultivated forest frogs is low, and captive forest frogs are imperative. After years of research and discussion, the author has summarized six key technologies to be mastered in captive forest frogs. 1 Hatching management is the first step. The egg mass is selected. Generally, the egg mass produced within 2 days is placed in a disinfected hatching pond, and the unfertilized egg mass is removed to improve the hatching rate. The density of the egg mass during the hatching process should not be too large. For example, when the water source is sufficient, 10 to 15 eggs/m2 are charged according to labor. The egg mass should be evenly distributed in the hatching pond. The second is the temperature of the hatching pond. The temperature includes air temperature and water temperature. It is the most direct external condition affecting the hatching of frog eggs. The higher the temperature, the faster the embryonic development speed and the shorter the incubation period. On the contrary, the embryonic development speed is slow and the incubation period is long. However, during the incubation process of forest frog eggs, the temperature requirements for each stage of embryonic development are different. The water temperature should be kept above 6℃ in the early stage of egg mass incubation, and between 16 and 24℃ in the middle and late stages. Due to the different temperatures in the early and late stages, the water temperature can be adjusted by covering with plastic film and irrigating with water to ensure that the frog eggs develop normally at a suitable temperature. The water quality in the hatching pool should be kept fresh, not turbid, without sediment, and without pollution, because the mixed sand in the water will pollute the egg mass, causing "water eggs" and reducing the hatching rate. Therefore, it is necessary to ensure that the hatching pool has neutral and fresh water. 2. Tadpole cultivation 2.1 Tadpole density The density of tadpoles can be larger in the first two weeks of tadpole cultivation. As the age increases, the density can gradually decrease. The method of artificial evacuation and sub-tank is used to reduce the stocking density. The general stocking density is: 2000-3000/m2 for 1-15 days old, 1500-2000/m2 for 15-25 days old, and 500-1000/m2 from 25 days old to metamorphosis. If the density is too high, the tadpoles will grow and develop slowly, with low survival rate and weak physique, which will affect the survival rate of metamorphosis froglets. 2.2 Feed When the tadpoles have eaten their own egg membranes, they can be fed with starter feed, usually cooked egg yolk or soy milk. Wrap the cooked egg yolk with two layers of gauze and shake it slowly in the pool water. The egg yolk will dissolve in the water and the tadpoles can eat freely. Later, depending on the feeding situation of the tadpoles, they will be fed with artificial compound feed as appropriate, so that they can eat nothing or little left after 2 hours of feeding. When the tadpoles grow to 20 days old, animal feed should be added to meet their growth and development needs. 2.3 Water quality and water temperature Good water quality has a direct impact on the growth and development of tadpoles. Cold, polluted, and mineral-rich water are all very detrimental to the growth and development of tadpoles, and will hinder the development of embryos and the formation of various organs. Tadpole excrement and other impurities will also cause the water quality to change color. If this is found, the pool water should be immediately drained and new water should be injected. In the early stage of tadpoles, new water should be injected once every 5 days, and the water surface should be sprayed with 0.3mg/mL bleach solution. In the later stage, the water temperature should be lowered by single irrigation, and the water temperature should not exceed 24℃. If the air temperature and water temperature are high, water changes and shade should be adopted to lower the pool water temperature. Otherwise, tadpoles are prone to various symptoms, and in severe cases, they will die. 3 Tadpole metamorphosis Tadpoles enter the metamorphosis period after 30 days of growth. At this time, the metamorphosed tadpoles should be moved to the metamorphosis pond in the forest frog circle in time to avoid the phenomenon of young frogs escaping if the pond is moved too late. The forest frog circle should be surrounded by two layers of inner and outer walls with plastic or other materials, that is, one layer for the small circle and one layer for the overall frog farm to prevent the forest frog from escaping. During this period, management should be strengthened and feeding should be done carefully. Because the transformed young frogs are more than half lighter than the metamorphosis precursors, and they do not eat during metamorphosis, and the energy consumption is large. If the management is not good, the young frogs are not strong and the mortality rate is very high. Management during the metamorphosis period: First, ensure that there is enough water in the metamorphosis pond and keep the water temperature below 28℃ to avoid high temperature causing the death of metamorphosed young frogs; second, continue to feed the tadpoles. Tadpoles that have not entered the metamorphosis period need to continue to eat food, and sufficient food must be supplied. 4 Disease prevention and control Captive forest frogs suffer from different diseases at different stages. When feeding, a comprehensive method of prevention and control must be adopted. 4.1 When tadpoles are reared for 18 to 20 days, they are prone to gas bubble disease due to high temperature, high food intake, and excessive gas in the water. The prevention and control methods are: during the tadpole rearing period, new water is frequently injected into the pond, disinfection is performed once every 5 days, and excessive feed is not fed. When gas bubble disease is found, new water is immediately injected or the tadpoles are moved to a clean water pond. Second, 3g of salt mixed with water is sprinkled per cubic meter of frog pond to prevent and control this disease. 4.2 The young and adult frogs are mainly reared in the summer. Due to the overgrown weeds in the enclosure, the cool and humid environment, and the high stocking density, there is surplus feed, which allows various bacteria to breed and multiply. Therefore, the breeding of forest frogs must be disinfected frequently to prevent forest frogs from getting sick. During this period, forest frogs mainly suffer from diseases such as red leg disease, skin rot, and enteritis, with a high mortality rate. Preventive measures: Thoroughly disinfect the frog pen once before stocking the forest frog in summer. Disinfectants such as bleaching powder can be used. Disinfect the frog pen with 0.7×10-6 potassium permanganate or 1-2×10-6 bleaching powder solution every half month during the summer feeding period. At the same time, mix 0.5g of enhanced sulfamethoxazole into 1000g of insects every month and feed them for 3 consecutive days to prevent forest frog enteritis. Spray and disinfect the mealworm breeding site with 0.3×10-6 bleaching powder solution once every half month to prevent forest frogs from eating infected insects. Disinfection facilities are installed at the entrance of the frog pen. Disinfection is required before entering the frog pen. Outsiders are not allowed to visit. 5 Wintering management The wintering period of frogs in the northeast region of Kanto is as long as 6 months. Although forest frogs do not need to be fed during this period, the management of wintering forest frogs cannot be ignored, otherwise various unexpected situations will occur, resulting in the death of a large number of forest frogs.

Don't even think about it if the bait problem can't be solved. You will definitely lose money. Think about it, with such a high density, eating is a big problem. Otherwise, there is a possibility of starving to death. Any animal has an output ratio.
