Techniques of artificially imitating natural breeding spines and frogs

The spine-breasted frog is also called a stone frog, a stone stick, a rock frog, and a pheasant. Adult frogs generally have a body weight of 200-400 grams, which is a unique large-scale wild frog in China. It is not only nutritious and sweet, but also has medicinal properties such as healthy liver and lungs, clear heart tomorrow, UFA hair, and dysentery. Due to the increasing demand for spiny-breasted frogs and the declining demand for wild resources, the market price of spines and frogs has also risen sharply. Artificially imitating natural breeding of spiny-breasted frogs is to use the existing natural environment for breeding, which not only saves a lot of investment in building pools, but also grows rapidly and causes fewer diseases. Therefore, artificial imitation of natural breeding spiny-breasted frog has good economic benefits and a very broad prospect.
1. Selection and Construction of Sites Because of its physiological characteristics of high temperature, dryness, noise interference, and strong light irradiation, the selection and construction of spiny-breasted frog farms requires shading, tidal temperature, and quietness. If there is no ready-made site with good natural conditions, appropriate settings and transformations can be made using a semi-appropriate natural environment, making it a favorite habitat for spiny-breasted frogs. For example: the use of dense woodland ditch ditch water culture; the use of long-term flow of mountains, streams, create shaded objects breeding; the use of bamboo and evergreen orchards do not have ditch farming; can also use deciduous orchards or crop garden planting evergreen Plants and constructing gully farming, etc. As long as the shade is dense, the site is moist, and the water quality is cool, it is an ideal spiny frog farm. The condition of shaded conditions directly affects the wetness of the breeding grounds and the coolness of the water quality. If the natural shade is not sufficient, a shading shed can be set up. It is better to cultivate fast-growing evergreen vine plants and make them climb into a green shade net. To achieve the ideal shade effect. Now people often cultivate black tiger heads (characteristics and effects of which are described in the "Compendium of Materia Medica"). It is ideal for shading. This well-developed and tough vine grows very quickly. Many vines can be produced in a year. Some vines can be wound more than 10 meters in the year. Large and thick leaves do not fall all year round. The fruit can be hung for two years. Each fruit weighs 1 to 1.5 kilograms. It is sweet and honey, and it is extremely resistant to shade and drought. For example, it can be planted in an orchard to grow spiny-breasted frogs. As much as the shady effects of deep forests and old forests, it is also possible to collect more fruits in one season.
The spiny-breasted frog is a burrowing amphibious animal that cannot be separated from water and caves. It is necessary to set caves that simulate natural conditions on both sides of the culture ditch, half of which is in water and half is on the shore. Bricks, stones, cement tiles, etc. can be piled up into movable caves so that they can be taken apart for collection. It is also necessary to plant shade-resistant flowers and aquatic plants around the cave to attract insects for frog prey, and on the other hand to purify the water and make the ditch more cool. Where conditions permit, the culture ditch can be opened into a “w” shape to increase the length of the culture ditch, thereby increasing the culture area. The culture ditch should be narrow and wide on top to form an inclined surface so as to facilitate the landing and predation of the frog. Every 5 to 6 meters to be digging a long, wide, high 1.5 meters deep water scorpion, in order to facilitate the spine chest frog lurking underwater safe winter, you can also breed small fish shrimp for spiny-breasted frogs prey. If it is a new cement ditch, it can be used to raise the frog for more than 10 days to prevent the precipitation of salt on the frog. It is also necessary to apply a layer of mud to the surface of the cement to facilitate the planting of plants and spines. . The spine-breasted frog is also a small animal that is very much in love with the nest. Once settled, it is generally not free to migrate, unless the depletion of water sources, environmental degradation and other factors forced it to escape. Therefore, artificial imitation of natural spines and frogs do not need to be set up to prevent escape, and they will not be lost.
2, the introduction of seedlings introduction of spiny-breasted frogs generally have to capture wild frogs, collecting wild maggots and transplantation of fertilized eggs in three ways. However, due to the deteriorating environment and excessive overfishing in recent years, wild resources in many places are in danger of extinction, and seedlings needed to be bought from other places. Therefore, when introducing frogs, care should be taken not to purchase the frogs on the trader's stands. Because most of these frogs were obtained through several hands, they were bruised and easily infected, and some of them died of frogs that had been stored for too long. They were dying, and their survival rate after buying was low. It is best to go to the place where there are wild spiny-breasted frogs to catch or go to the spiny-breasted frog farm. Male frogs are larger in size, have thicker forelimbs, have cysts and keratinocytes in their chests, and are not evident in the abdomen during the breeding season. The female frogs were smaller in size, with smaller forelimbs, no abdomen and horny thorns in the abdomen, and enlarged abdomen in the breeding period. The introduction of spiny-breasted frogs can not be a male and female, male and female should be 1:1 pairing, introduced into the frog is best carried out in the fall, after the lead back to stocking in the ditch of the ditch of natural water overwintering, until after the Ching Ming Festival in the next year naturally hold the breeding, as long as The water level in Sham Shui Po remains around 1.5 meters. Even in the north, wintering is safe. Fertilized eggs or cockroaches can also be introduced during the breeding season, but they are vulnerable to natural enemies in the early stages of hatching and young frog breeding. For example, grasshoppers, rodents, snakes, otters, otters, carnivorous fish, etc. are all frog eggs. The natural enemies of Hexie have seriously affected the survival rate of young frogs. Therefore, it is better to introduce frogs. It is better to collect the fertilized eggs produced by these species of frogs and pool them together. After the frogs are intensively cultivated and then placed into the farm at a certain density, the natural enemies can be greatly avoided and the survival rate can be improved.
3. Cultivation of young frogs The frog eggs that are produced by spiny-breasted frogs will be picked up gently with a scoop of water for 3 days, put into a container with clean water, and transferred to the hatching tank or hatching box for hatching. Care should be taken not to accumulate squeezing. If it is difficult to separate frog eggs that adhere to stones or other objects, place them in the hatchery as they are and do not crush or injure frog eggs. The hatchery should be built in a place where the water quality is fresh and well-shaded. If there is no shade in the natural forest, cover it with a awning to prevent the direct sunlight from affecting the survival rate. If the hatchery is built with cement, it should be built 20 days in advance and filled with water. The pool depth is 70 cm, 1.5 meters wide, and 3 meters long. It also requires the injection of flowing water. Where there is no long-term flow of water, it can be pumped by a goldfish tank pump to make the hatching pool flow slightly, where conditions permit. , hatching cages can be set up in Qingshuitang or Qingshui River with moderate flow rate and suitable water temperature for incubation. Net cages can be made with sieve baskets. Each cage should be 1.5 meters long, 0.8 meters wide and 0.5 meters deep. Net cages are also suitable. Take shelter and avoid sun exposure and heavy rain. The water temperature is appropriate to 16 ~ 30 °C, water temperature is too high or too low will affect the development of frog eggs embryo. Keep the water depth between 30 and 40 cm. Keep the frog eggs below 5 cm above the water surface. After about 15 days of incubation, one tail cricket will break out of the membrane. The newly hatched earthworms have poor adaptability to the ambient temperature and should be kept in the hatchery pond for 10 to 20 days. It is also possible to continue breeding young frogs in hatching cages or hatching ponds. When hatching the cage, it is necessary to raise it from the water surface during the metamorphosis period to make it a “ramp” shape, making it easier for paralyzed landings. Also add appropriate amount of field mud or garden soil in the cage to facilitate the intake of required minerals. If it is a hatchery, it is also necessary to put one side or head slightly higher to make it "sloped" for landing and catching young frogs. During the flood season, the feed is mainly plant-based, and it can be fed with bean curd residue, wheat bran, melons, and tender vegetable pulp. With the growth of cockroaches, more animal feeds can be gradually fed to promote rapid growth and early metamorphosis. Such as cockroaches, mealworms, fly maggots, animal blood, etc., to cut fine to feed. When the beak becomes a young frog, wet gauze can be used to lay it on the "slope surface" and use its landing habits to collect and transfer it to the farm. The density should be about 80 per square meter.
4. Feeding snakes into frogs is a natural enemies of young frogs. It is best to remove the snakes from the breeding farms before stocking the frogs, but the snakes are protected by the state and their economic value is also high. Use a "plum basket" trap, catch it, and release it to other places away from the farm. After larvae are stocked, due to the high density, natural food alone is not enough, and feed sources must be widely opened. Fishes, shrimps, screws, etc. can be stocked in cultivars for frogs to feed on frogs to provide enough aquatic food for frogs. Where conditions permit, 8-15W fluorescent lamps or incandescent lamps can be used to trap frogs at the deepwater rafts of the culture ditch. The installation height should be 20-30 cm, but care should be taken to prevent leakage during rains. It is advisable to breed some fly maggots and mealworms accordingly to ensure the feed supply of the spiny-breasted frogs. Musca domestica and Tenebrio molitor are the best bait for breeding spiny-breasted frogs, because they are not only easily digestible high-protein but also slow-moving white animals. They are easily found by frogs, are not easily lost, and are easy to culture and cost. When feeding, the maggot should be rinsed clean, and then filled with a leaking container that will enable the fly to crawl on its own, and the leaking container tied into a basket with a rope. When it is dark, it should be hung above the deepwater ridge of the culture ditch. The height is 1.5 meters. Because the predation activities of spiny-breasted frogs are carried out at night, and they are particularly agile for catching flashing live bait, these fly larvae and yellow mealworms, which have been drilled out of their own hands, and flying insects lured by lights, often He was caught by the frog before he fell to the surface. As long as the position of the hanging bait is fixed, the frog will soon form a kind of conditioned reflex. When night falls, it will “consistently” “concentrate” with “dinner” in the “old place”. At this time, it is necessary to observe which frog has more larvae and less food by means of light trapping insects; which frogs have less frogs, and there are surpluses so that the feed can be increased or decreased as appropriate. If you feel that it is inconvenient to feed the bait at night, you can gradually domesticate it for feeding during the day. The method is to postpone the feeding for half an hour every night. You can push it at 8 o'clock in the morning to 8 o'clock every month, but it is not good for the feeding during the day. Light trapping. At temperatures above 30°C or below 8°C, spiny-breasted frogs are in a state of hibernation and hibernation. They rarely feed or stop feeding and may not feed on food.
5. Artificial imitating natural breeding of spiny-breasted frogs of spiny-breasted frogs. Due to the wide area for breeding and the inhabiting sites are numerous and complicated, there are inconveniences for their recovery. Three types of returning methods are now introduced. reference. 1 According to the law, using the habit of spiny-breasted frogs buzzing out and fearing strong light, they are illuminated with a flashlight or miner's lamp on a sweltering night. The spiny-breasted frogs can see sudden bright light and will sit still on rocks or ravines. On the other hand, you can use a dip net to cover the frogs first, and then capture the frogs from the dip net. It is best to use the hand net when you feed the food to “finish the nets,” and sometimes one net frog is caught. 2 掏洞法 Thorough-breasted frogs are buried in caves during the day and like to live in groups. They can use a large dip net or hand net to cover the entire cave and then open the stones in the cave. The frogs in the cave will flee into the net. Therefore, if caves are to be built, they can be easily recovered. 3 drainage method This method is suitable for winter catch. In the winter, most of the spiny frogs hibernate into the soil of Sham Shui Po and hibernate. As long as the leeches are drained and the pinch soil is gently pinched by hand, the overwintering spine frogs in the larvae can be caught. Sometimes a otter can retrieve dozens of frogs. jin. The spiny-breasted frogs used as seedlings should not be caught in the winter so as not to suffer the impact of freezing on the breeding of the following year. Therefore, when the water is drained during the winter, a certain amount of blisters should not be disturbed.
6. The safe transportation of spiny-breasted frogs The introduction and sale of spiny-breasted frogs require safe transportation. Containers for transportation should also be emphasized. They should not be packed in rough bamboo containers to prevent them from touching the frog body. They must not be overloaded in one container to avoid injury caused by overlapping extrusion. It is best to use a plastic foam box, because the foam is not only light, but also insulation and cold, and then use a plastic foam board and polyethylene mesh sheet nailed into a 10 cm high flat box stacked in the box, can increase the dressing area. In a foam box 80 centimeters long, 70 centimeters tall and 50 centimeters wide, 6 flat boxes of 10 centimeters high can be stacked, and 80 can be filled in each flat box. The whole box can be packed into more than 480 frogs at a time. If it is a baby frog, it can hold 4,500. Before transport, press the size of the foam box to make ice cubes at the bottom of the box. The thickness of ice cubes can be determined according to the distance of transportation. Each flat box is also covered with a layer of soaked sponge, aquatic grass, moss, etc. to ensure that the frogs are cool and moist. A small hole is worn on both ends of the foam box to prevent oxygen deficiency in the box. The entire operation should avoid high temperature environment and sunlight, and the action should be gentle and quick. According to the author's experience, 5 cm thick ice cubes can be maintained for 3 days. When transported, the ice cube thickness can be increased or decreased according to the transport time. After reaching the destination, if it is sold, it can continue to put ice cubes without feeding food, because the spiny-breasted frog is a very hungry animal. Under proper temperature conditions, you will not starve to death without feeding for six months. If it is introduced, quickly transfer it to the farm at a ratio of 1:1 male and female and a certain density. Don't frequently catch and transfer afterwards to avoid affecting tranquility. Do not insert frogs randomly to avoid new frog species being bullied. Or cause mutual killing.
