The climate is mild, and there are a lot of river and lake beaches and marshes, which are very suitable for the growth of bullfrogs. A 'bullfrog habits 1. Habitat Bullfrogs inhabit lakes and marshes, creeks, ponds and other water environments, caves, cool and damp places are the most suitable habitat for bullfrogs, such as the surface of the water long floating plants, then prostrate in the water plants, only to the head exposed to the surface of the water, in the event of disturbances will be quickly submerged in the water. Bullfrogs have the habit of living in groups, often a few or dozens of *** habitat, when adapted to an environment, it will not be easy to move to a different place.2. Activities Bullfrogs spawn in shallow water. Foraging activities are carried out in shallow water or wet land not far from the water.3 Eating The tadpoles of bullfrogs are very different from those of metamorphosed frogs. The tadpole period is very different from the feeding of animal feeds (e.g., daphnia) and artificial feeds such as fish, egg yolks, animal offal, animal carcasses and other animal feeds, as well as potatoes, soya bean dregs, rice bran, maize flour, watermelon rinds, and fruits.　　Second, the feeding of bullfrogs, a young frog feeding management in general, the gonads have not matured, the individual bullfrogs in the 100 grams or less is called young frogs. Just after the metamorphosis of young frogs, the adaptive ability is very poor, feeding and management work should be meticulous, the good or bad management of this period has a great influence on the whole frog production. If the tadpoles continue to be kept in the tadpole pool after metamorphosis into young frogs, their growth will be affected due to uncomfortable conditions or excessive density, so they have to be transferred to the young frog pool for rearing. 1. Young Frog Pool The tadpoles become young frogs when they have grown up with all their limbs and have their tails removed, so the young frogs and tadpoles have to be reared separately. The area of young frog ponds depends on the scale of production, 1~2mu for small-sized frogs, 5~10mu for large-sized frogs, and the depth of water should be 0.5~0.8m. Both earth and cement ponds can be used for rearing young frogs. Earthen and cement pools can raise young frogs, but the effect of earthen pools is better (Figure 4, 5). General tadpole ponds can also be used to raise young frogs, but some floating plants should be placed on the land around the pond or in the pond as a habitat for the young frogs. If it is a small concrete pool, a cooling canopy must be built in summer to prevent the water temperature from getting too high; the bottom of the earth pool should be solid, leaving 3-5 centimeters of thin mud. Other conditions are basically the same as those of spawning pools. Figure 4: Section of young frog pond Figure 1: Section of young frog pond Figure 5: Section of young frog pond Figure 2: Stocking The stocking density of young frogs should be determined according to the size of the individual, generally stocking 100-150 newly metamorphosed frogs per square meter, after 30 days, the weight of the frogs reaches 25-50 grams, stocking 80-100 frogs, weighing 60-100 grams, stocking 60-80 frogs, if the conditions permit, it can also be appropriate to increase the density. At the same time, we should also consider the climate factor, summer weather is hot, the density should be a little thin, winter and spring density can be increased appropriately. The same pool of young frogs, in the same environmental conditions, its growth rate is not consistent, according to the size of the frog body should be divided into pools to feed, otherwise it will produce the phenomenon of big frogs eating small frogs, seriously affecting the survival rate of young frogs. 3. feed and feeding The feed of newly metamorphosed young frogs is based on the fly maggots and small earthworms and other small animals. The feeding method is to put the feed on the feed tray or spread it on the fixed feeding point near the pool. On average, every 100 young frogs should be fed 100~150 grams per day. When the frogs grow to 15~20 grams, they can be fed with small fish, shrimps and larger earthworms, etc. The average daily feeding is equivalent to 10~15% of the weight of the young frogs. Bullfrogs in 25 ~ 30 ℃, feeding ability is the strongest, the temperature is too high or too low, the amount of food will be reduced, or even stop eating, this is a normal phenomenon, do not have to worry, but the amount of feeding can not be rigid, according to the specific circumstances. The daily feed can be fed once or twice, and it is proved by practice that it is better to feed twice to avoid the uneven phenomenon of "sharing food". Bullfrogs from tadpole metamorphosis into young frogs, can only ingest active bait, static feed blind, some people believe that this is because the bullfrogs two eyes are widely spaced, can not form a binocular vision. If we can develop an artificial simulation of biological behavior feeding machine or other methods to make static feed "activation", bullfrogs can also be ingested. It has been reported that it can be made to ingest dead animal feeds and artificial feeds through tame feeding. The method is to reduce the live bait and mix it with a small amount of "dead feed" in the late stage of metamorphosis. However, in the short term of tadpole metamorphosis into young frogs, due to the change of body condition, short-term feeding suspension may occur, so there is no need to be alarmed. After the tadpoles metamorphose into young frogs, we will supply them with artificial feeds (dead feeds) in order to cultivate their habit of feeding on dead feeds, but we still have to mix live bait with "dead feeds". The "dead feed", such as big fish, animal offal, etc., should be cut into granules or strips according to the size of individual frogs, or made into artificial pellet feed. At the beginning of tame feeding, you can put the artificial feed into the feed pan, and then put several live loaches into the feed pan, half of the feed pan will be sunk into the water, half exposed to the water surface, the live loaches in the feed pan to drive the artificial feed in the pan, the young frogs see all the feed in the pan are vibration, that all are live bait, they will rush to eat. If there is no live loach, a bucket of water can be installed on top of the feed tray, and a small hole can be opened at the bottom of the bucket, so that the water in the bucket will keep dropping in the feed tray, and the feed in the tray will fluctuate with the vibration of the water in the feed tray, which will make the bullfrogs mistakenly think it is a live bait and rush to eat it. If the body weight is more than 50 grams, light can be used to attract insects to make up for the lack of feed. Some people think that they can make bullfrogs fully ingest dead feed by taming feed, the method is to make mixed feed with animal meat, offal, all kinds of melon and fruit peel, bean dregs, rice bran, etc. In the young frogs within one month after metamorphosis, two thirds of live bait and one third of the mixed feed are fed for a month and a half, and then change it to one third of the live bait and two thirds of the mixed feed, and then all of them will be supplied with the mixed feed in three months' time, and then they will be tamed and trained for a long time, and then the bullfrogs will be fed for a long time. After three months, all the mixed feed will be supplied, so that it can be tamed gradually, and the habit of eating dead feed can be formed after a long time. Another way to tame the bait is to make expanded feeds of animal and plant feeds according to a certain proportion, and build a larger feed table at a fixed point in the frog pond. When feeding, soak the feed table in about 4 centimeters of water. At the beginning of feed taming, the puffed feed and live feed such as fly maggots, loach, etc., twice a day, regular, fixed-point, quantitative feeding, through a few days of taming, can form a conditioned reflex, and then all changed to feed puffed feed, frogs still come to take food, due to the frogs keep moving to make the water fluctuation, as a result, floating in the water surface of the puffed feed also keep swinging, the frogs think that it is a live bait, can be ingested, the taming method is better. This taming method is more effective. No matter which method is used, the mixed feed should be made into pellets, and the size of the pellets should be according to the size of the frog body, and it is suitable for it to be swallowed by one mouth. Regardless of live or dead feed, there should be a fixed feeding point, general feed feeding to the feed pan is appropriate, some feed (such as earthworms, etc.) should not be placed in the water, but also in the feed table near the shore of the pool to set up a fixed feeding point, not only is conducive to the domestication of the operation and management is also convenient. Different feed on the growth rate of young frogs and survival rate also has an impact, to fly maggots, fish fry, castor worms, loach, earthworms, etc. as feed, the feed coefficient of fish fry and loach 4, 40; fly maggots 22.7; castor worms 3.79; but fly maggots can be used as a metamorphosis of the early stage of the feed of the young frogs, young frogs are small, can not swallow the fish fry, and fly maggots are tiny individuals, wriggle slowly, easy to be taken by the young frogs, the young frogs grow up a little, and then the young frogs, the young frogs, the young frogs can not swallow fish fry, and fly maggots are small individuals, slow, easy to be ingested. After the young frogs grow up a little bit, then mix and feed other feeds. The growth rate of bullfrogs is "S" curve, i.e. slow-fast-slow law, 3-8 months old, the weight between 75-450 grams shows the growth advantage. The feed tray is generally made of wooden boards nailed to a frame of about 120 cm long, 80 cm wide and 8 cm high, and the bottom is nailed with 40 mesh/cm2 nylon window screen. The bottom of the feed tray immersed in water about 5 cm; water is too deep, bullfrogs are not easy to feed, too shallow, small fish and shrimp are easy to die, it is best to be fixed in the water like a fixed net box, in order not to get into the tray to eat too much frogs and make the feed tray sink. Also according to the above requirements, with cement in the pool as a fixed feed tray, but the pool water must be maintained at a fixed water level, to ensure that the cement feed tray in the water.4. Feeding management General feeding once a day (some people think that as long as the feed is sufficient, can be a few days to throw a time), before feeding, you must remove the residual feed in the feed tray to check whether the feed tray is in good condition. After feeding for a certain period of time, young frogs of different sizes should be fed in a graded manner to prevent big frogs from eating small frogs. In order to accelerate the growth, it is also an important measure to give different stocking densities to frogs of different sizes. We should always check whether there are holes and gaps around the enclosure wall and door, and plug them immediately to prevent the bullfrogs from escaping. Eliminate weeds around the pool, drive away snakes, rats and other enemies in time, and keep the pool ventilated and cool, and the water quality fresh. Most of the frogs are overwintering in the stage of young frogs, and the survival rate of young frogs during the overwintering period is closely related to the ecological conditions. The water depth of the overwintering pond should be kept above 70 centimeters, and the bottom of the pond should be silted to a certain extent, and the pond should be covered with reeds, winter thatch and other coverings, which can not only keep the temperature warm, but also prevent the entry of some enemies. Overwintering survival rate can reach more than 90%. If the water level is too shallow and there is no silt at the bottom of the pool, the survival rate is very low. The feeding management of adult frogs and parent frogs is the last link in the whole bullfrog breeding process, which is also the most important production program. At present, bullfrog breeding can be divided into two ways: intensive breeding and rough breeding. Rough rearing is to release the frogs in a wider place and let them grow naturally by utilizing natural bait, while intensive rearing is to use smaller pools and artificial baiting for high-density breeding. The following mainly introduces the way of intensive breeding.1. Frog breeding ponds Adult frog breeding can generally use pond weirs, lotus root ponds and small natural ponds with a little finishing and transformation. The location should be chosen in a place with flat terrain, sufficient water source, convenient drainage and irrigation management, no flooding, no drying up in drought, and it is more ideal if there is flowing water. The adult frog pond is 300 to 1000 square meters. In addition to the water surface, the soil frog pond should have a certain area of land around and in the middle of the pond, and the ratio between land and water surface is 1:1. The slope of the pond should be large, so as to facilitate the landing of bullfrogs to rest and catch food. The depth of water should be determined according to the thickness of local winter ice, and it should be ensured that there is still a certain depth of water under the ice layer in winter so that the bullfrogs can spend the winter safely at the bottom of the pool, and the depth of water in the Yangtze River Basin should be kept at 1~1.5 meters. When raising frogs in cement pools, there should be wire mesh at the mouth of the pools to prevent the frogs from escaping and the invasion of enemies. For earthen pools, barricades should be built. Bamboo curtains, bamboo fences, barbed wire, nylon nets and brick walls are used as barriers. Because bullfrogs have the habit of digging holes in the soil, so the barrier wall in the soil to be buried under 30 centimeters, but also because the bullfrogs can jump high and climb to escape, so the height of the barrier wall on the soil part of 1.5 ~ 2 meters. Bamboo curtains and fences are used as barriers, and the size of the gap and the mesh of the wire and nylon nets should be determined according to the specifications of the frogs to be kept. In order to create a good living environment for bullfrogs, a natural environment suitable for bullfrogs should be arranged in the frog pond. The main thing is to plant some aquatic plants such as lotus root, cecropia, calamus, wild rice, watercress and so on in the frog pond for the bullfrogs' habitat. In the pool that is also used as a spawning pool, some aquatic plants such as goldfish algae, horse chestnut, water lilies and polymer grass are also planted to facilitate the spawning of bullfrogs. The land ridge slope should be planted with flowers and grasses to attract insects and increase the feed for frogs. Bullfrogs are afraid of heat, and the optimal water temperature for adult frogs is 23～30℃. You should also plant shrubs and trees along the shore of the pool or build small shade shelters to reduce the temperature for the bullfrogs to live in. In hot summer, it is better to change the water once a day, the amount of water changed is 1/2, and the temperature difference between the old and new water is 1～2℃. Bullfrogs also have the habit of living in caves, so it is better to dig some artificial caves at the edge of the ridge for the bullfrogs to rest in the summer. Through this arrangement, the frog pond can make the whole environment more suitable for bullfrogs' habitat and life, so as to promote the growth of bullfrogs and improve the survival rate of rearing. 2. stocking, bait and management (1) stocking: the breeding density of adult frogs is generally 20-50 per square meter, and the density is adjusted according to the size of the adult frogs and the level of breeding management, water temperature, water quality and other factors as appropriate. (2) Bait: Bullfrogs eat bait in the natural environment, mainly houseflies, wasps, ants, tortoiseshells, knockworms, aphids, dragon lice, step bugs, scorpion bugs, hunting stinkbugs, dragonflies, praying mantis, crickets, mole crickets, locusts, spiders, snails, snails, loaches, carps, salamanders, tortoises, turtles, snakes and other frogs. Therefore, it is necessary to install insect attracting lamps in the artificial frog pond to attract insects as frog bait. But in the artificial high-density frog farming, rely solely on the collection of insects can not meet the needs of the growth of bullfrogs. According to the test, mysis shrimp, small fish, fecal maggots and small earthworms are the favorite bait for young frogs that have just metamorphosed. However, in large-scale production, it is obviously impossible to rely on eating these baits alone. Should be in the young frogs to grow to about 50 grams in the live bait mixed with silkworm pupae, mussels, snail meat, animal offal and other animal bait, which will be put together in the special bait table and bait plate, through the live bait and bullfrogs themselves in the bait table and bait plate jumping, so that the static bait jumping, bullfrogs mistakenly think it is a live bait and scramble to catch food. When the bullfrogs get used to feeding in this way, then gradually increase the proportion of static bait until all static bait is used to replace live bait. The eating capacity of bullfrogs is very large, a bullfrog can catch 8 locusts within 1 hour from 12 o'clock in the night to 1 o'clock in the next morning; it is also observed that a bullfrog eats 13 mole crickets within 15 minutes. In captivity, the amount of food consumed by bullfrogs varied from 5 to 20% of the total body weight of bullfrogs, depending on the temperature. The bait coefficients of bullfrogs on several baits after ingestion were roughly as follows: net fish 3.6, animal offal 5, insects 10, and dried defatted silkworm pupae 3.5. Although there are a lot of live feeds for bullfrogs, the more successful and easy to form a scale of production in live bait culture and application is the cultivation of earthworms and yellow mealworms at present. In recent years, the aquaculture department of Sichuan College of Animal Husbandry and Veterinary Medicine has been raising young frogs and adult frogs of 50 kg each with chopped fresh pig's lungs, and the young frogs have an average body weight of 25 g. The average daily input of pig's lungs is 2.5 kg, and the frogs are collected in 130 days, with an average body weight of 150 g and a maximum weight of 240 g, and baiting coefficient of 1.6. The adult frogs have an average body weight of more than 150 g, and the daily input of pig's lungs is 2.8 kg on the average, and the frogs are collected in 350 kg, with an average body weight of 3.5 kg, and the average bait coefficient of 1.6. The average weight of adult frogs is more than 150g, the average daily feeding is 2.8kg of pig's lungs, and the feeding is 180 days, 350kg of frogs are collected, the average weight of frogs is 502g, the maximum weight of frogs is 709g, and the bait coefficient is 1.68. Adult frogs are large and have a large amount of food intake, so they can ensure enough high quality palatable bait and control the appropriate environmental temperature, so their weight growth is relatively fast, and their individual weight gain is about 30-50 grams per month. Parent frogs eat a large amount of food, generally each daily bait for 10% of the body weight, the bait should be more types of comprehensive nutrition, of which animal bait should not be less than 60%. Frogs in estrus, the amount of food intake is reduced, holding pairs, spawning, spermatozoa basically stop eating, and then the amount of food intake increased greatly. The amount of bait should be increased or decreased according to the above situation. (3) Feeding management: bullfrogs in intensive feeding conditions, eating a large amount of food, feces, easy to pollute and deteriorate the water quality, thus causing a variety of diseases. This situation is more prominent when raising adult frogs in cement pools, so the cement pools should be washed and scrubbed diligently, replaced with new water, and also disinfected with quicklime and bleaching powder regularly. Although there is soil adsorption effect in soil ponds for rearing bullfrogs, it is necessary to refill or replace new water regularly, and if there are conditions of running water, it is better to use running water for rearing. Escape prevention is a very important part of bullfrog rearing management. The escape prevention equipment must be overhauled frequently, and the holes on the embankment should be blocked in time to prevent the frogs from absconding from the holes. In rainy days, bullfrogs are especially active in jumping and climbing, so it is more important to pay attention to escape prevention. Bullfrogs have a lot of enemies, field mice, moles, cats, snakes, birds are its natural enemies, and active measures must be taken to catch and expel them.3. Growth of bullfrogs In Jiangsu area, the artificially bred bullfrogs can grow up to 50 grams one month after metamorphosis, 130~150 grams in two and a half months, 350~400 grams in the second year and 700~800 grams in the third year, which reaches the requirement of commercial specification.4. 4. Before the transportation of bullfrogs, wash the mud and other pollutants adhering to the frogs, and then put them into the frog cage made of bamboo. The frogs should not be overcrowded, not to mention overlapping. The bottom of the cage should be covered with water grass to keep the frog's skin moist, and also to reduce the temperature, especially in summer, the temperature is high, and there should be a certain gap between the frogs. In case of long distance transportation, the frogs should be placed in a ventilated and cool place and sprinkled with water every 6 hours. No feeding is needed during transportation. The frog cage is made of gabion, with a volume of 50×50×20 cm, a round mouth, a caliber of 10-12 cm, and a cover, which is light, ventilated, and inexpensive (shape as in Fig. 6). Other containers such as barrels, iron barrels, wooden boxes, cartons, etc., as long as there are ventilation holes, can be ventilated, there are small holes at the bottom, can be filtered out of the sewage, can be used as a tool for transporting frogs, but should not be too high, so as to avoid frogs jumping too much inside the container and bruises. The transport density of immature frogs is 200 to 2000 per square meter according to the size of individuals. If the frogs are transported in plastic boxes, the boxes can be stacked on top of each other to improve the transportation efficiency. Adult frog transportation due to large individuals, strong jumping force, so it is appropriate to separate into small rooms in the container, filled with wet water plants or wet cloth, each small room to put 3 to 4 adult frogs. It is better to put each frog into a small soaked gauze bag and then put it into the small chamber, cover it with a small amount of water plants, and then cover it with a lid. This can prevent frogs from jumping and injuring themselves, and also prevent them from crowding and crushing each other to death. Figure 6 Frog Cage V. Enemies and Disease Control of Bullfrogs Bullfrogs are generally not easy to be infected with diseases, but under the condition of artificial intensive breeding, especially in the tadpole stage, they can be infected with parasitic and bacterial diseases. Bullfrogs and their tadpoles will be attacked by other biological enemies, if not prevented and controlled as soon as possible, it will bring significant losses to the production of bullfrogs. There are many enemies of bullfrogs and their tadpoles, such as water centipedes (dragonfly larvae), dragonfly larvae, wild fish (snakeheads, Mandarin fish and other carnivorous fish), turtles, soft-shelled turtles, frogs (especially tiger frogs and their tadpoles), birds, etc. All of them are the enemies of bullfrogs and their tadpoles. Rats, snakes, etc. can harm young frogs and adult frogs (including parent frogs), big frogs can also devour small frogs, and too many water mollusks in the pond can net tadpoles and young frogs to death. A water centipede can kill 20-30 tadpoles in a day and night, and the tadpoles with body length of 2-3cm are most victimized. In addition, it is also harmful to young frogs. Sprinkle 1~4ppm2.5% trichlorfon on the water surface to kill water centipede, which is harmless to tadpoles. Dragonfly larvae are quite harmful to tadpoles, and it mainly bites tadpoles to death from the abdomen. Spraying dichlorvos on the bank of the pool can prevent dragonflies from laying eggs in the pool. Water moccasin floats in the water, and it is hard for tadpoles or young frogs to get out of it. Copper sulfate (0.7~1.4g per cubic meter of water) can be used to kill it. Diseases and prevention of tadpole 1.Rotifera disease The whole body of the tadpole is covered with rotifers, and the naked eye can see the whitening of the mucous membrane of the caudal fin and the destruction of caudal fin tissues, and when it is serious, all the caudal fins will be corroded. The tadpoles will swim slowly, float on the surface of water and do not feed until they die. Preventive methods: reduce the breeding density, expand the space for tadpole activities; sprinkle copper sulfate in the whole pool before tadpole stocking, use 0.7g per cubic meter of water, or sprinkle 5:2 copper sulfate and ferrous sulfate in the diseased tadpole pool, so that the concentration of the drug in the pool water is 0.7-1ppm, which is an effective treatment for the disease of rotifers. Soak the tadpoles in 2% salt water for 5-15 minutes, which is also effective. 2.Bubble disease: The diseased tadpoles' intestines are full of bubbles, the abdomen is swollen, the body loses balance and floats on the surface of the water, which will lead to a large number of deaths if not rescued in time. Preventive measures: Do not use unfermented fertilizers to fertilize the water, do not use too much humus in the pool, feed the dry powdered feeds only after they are fully soaked and wetted, and feed the appropriate amount. If the aquatic plants are too proliferating in the pool, flush the new water every 2-3 days during the high temperature period and put up a pergola for shading to prevent the disease from occurring. If you find bubble disease, you should inject new water into the pool in time to prevent the disease from worsening, and put the tadpoles into fresh water for 1~2 days without bait, or put the tadpoles into clear water with 20% magnesium sulfate liquid sprinkled, and then put them back into the tadpole pool after two days, which has a better therapeutic effect. It is also effective to sprinkle the tadpoles with saline water.3. Tongue Cup Disease occurs in tadpole pools with poor water quality and high stocking density, and spreads very quickly. Tongue cup worms are mostly parasitized on the tail of tadpoles, and when it is serious, they are all over the body, and the naked eye can see the body surface is full of trichomes, which is very much like water mold. It can be treated by sprinkling 0.7~1g of copper sulfate per cubic meter of water.4. Anchovy disease parasitizes the slightly concave part of tadpole carcasses at the junction of the carcass and the tail, and the muscle tissue of the parasitized part is inflamed and swollen, and ulcerated when it is serious. The growth of tadpoles will be stagnated if 1 or 2 Lernaea are parasitized, and will die soon if 3 or 4 are parasitized. Prevention and control methods: The sick tadpoles should be dipped in potassium permanganate solution with a concentration of 1/50,000 to 1/100,000 for 10-20 minutes once a day for 2-3 days, and the worms will die one after another in two weeks. Tadpoles will appear floating head phenomenon when dipping and washing, and the small amount of oxidized mucus on the gills and the deposited trace of manganese dioxide should be washed off with water to ensure the normal respiration of the gills. Diseases and prevention and control of juvenile and adult frogs 1. Red leg disease and erythema Red leg disease is caused by viruses, and the hind limbs of frogs are red and swollen so that they are ulcerated; erythema is a localized redness and swelling of frogs' body, and when it is severe, it is ulcerated, and the cause of the disease is not known. The cause of the disease is unknown. Frogs suffering from these two diseases can be soaked in 20% sulfadiazine solution for 24 hours, which has a certain effect. It has been reported that high concentration of potassium permanganate solution soaking the sick frogs has better curative effect. Frog ponds with high morbidity should be filled with new water immediately to improve water quality. Before the onset of the disease, it should be prevented with drugs, splashing the whole pool with one millionth of bleach once a week, and often washing the food table and other frog tools with one hundred thousandth of concentration of bleach liquid. 2. rotting skin disease is caused by the lack of vitamin A. At the beginning, the back of the head of the bullfrog loses its luster. At the beginning, the back of the head of the bullfrog loses its luster and white pattern appears, then the epidermis layer falls off and rots, and finally it expands to the torso, all of which are white, and the color does not feed and die. Preventive methods: diversify the bait and feed other bait every 3-4 days to supplement the nutrition. Sick frogs with shark liver or pig liver, 1 gram per frog per feeding, once every two days, after a week of treatment, the frog skin regeneration, began to feed. 3. gastroenteritis Mostly occurs in April to September, highly contagious, sick frogs crawling, slow swimming, like drilling mud, the latter lying flat on the edge of the pool is not afraid of disturbance. Prevention and control methods: gastric dispersal tablets or yeast tablets twice a day, half a tablet each time, for three days. _. Sick frogs with shark liver or pig liver, 1g per frog per feeding, once every two days, after a week of treatment, the frog skin regeneration, began to feed.3. Gastroenteritis Mostly occurs in April to September, highly contagious, sick frogs crawling, slow swimming, like drilling mud, the later lying down on the edge of the pool is not afraid of disturbing. Prevention and control methods: gastric dispersal tablets or yeast tablets twice a day, half a tablet each time, for three days. I hope it can help you, huh1
