CATDOLL : CATDOLL: What conditions are needed to breed forest frogs?

1. What conditions are needed to breed forest frogs?

Choose a river basin with lush forests, sufficient water, and an area of ​​more than 100-200 hectares to establish a frog breeding farm. In the breeding farm, build 1 or 2 moon hole ponds for every 10 hectares. There should be drainage outlets and drainage ditches on the surface of the pond. The area of ​​the moon hole pond is 100 square meters and the water depth is 1. It must be more than 5 meters. The water quality is fresh. The hatchery should choose two sides, and the area varies from place to place. It is best to choose a location close to the forest. It is best to let the little frogs go up the mountain in time after metamorphosis. Use plastic film, bricks, galvanized sheets, and asbestos tiles to build frogs to prevent frogs from escaping. Fences are used to breed frogs. When frogs return to the pond for the winter, the water temperature of the pond is kept below 4. Straw, branches and other shelters are placed in the moon hole pond to make the Li Lin frog hibernate. Expansion information: Living habits Frogs have different living habits from other frogs. The annual life cycle can be divided into two stages: water vitality and land vitality.

Frogs stop eating, their activities stop, and their metabolic activity drops to the lowest level. After the underwater life period ends, frogs leave the Moon Cave waters and end their reproductive activities in the swamps. After a short period of reproductive dormancy in the soil around the spawning grounds or under the fallen leaves at high altitudes, they enter the forest and begin their life on land. This is the most active period of the year. Frogs consume a lot of food to meet their growth and development needs. The breeding ground should be as consistent with the living habits of forest frogs as possible. Choose a quiet environment, lush vegetation, and close to water. Frogs cannot be raised in factories, car traffic, environments with frequent human activities, noisy sounds, and places with severe vibrations. If an open space is selected as a breeding ground, the ecological environment must be artificially modified.

Generally, plants can be increased by planting cash crops such as grass or fruit planting. The breeding farm should be a place that is warm in winter and cool in summer. If the ground can be tilted a little to the southeast, the sun exposure area of ​​this terrain is relatively large, and the mild water temperature rises rapidly. In summer, it will be affected by the southeast monsoon. The changing water surface helps to increase the amount of dissolved oxygen in the water, which is beneficial to the reproduction and growth of frogs and water bait. Why is it not profitable to raise Rana? What conditions are required for raising Rana? What procedures need to be handled? The farm must be convenient for water source guarantee and irrigation and drainage. Generally, convenient water sources can effectively control water temperature, dissolved oxygen content in water, and pests and diseases, which is conducive to the growth and wintering of frogs. The breeding farm is conducive to free drainage and the regulation of pond water. There will be no floods in heavy rainy weather, and water can be supplied in time in case of drought.

The water used by a few farms may be related to the water source for farmland irrigation. It should be considered whether there is a contradiction between the two, and proper preparations should be made in the event of drought or drainage to avoid unnecessary losses. Choose a place with abundant bait, which can provide a variety of natural food sources such as plankton, insects, snails, loaches, miscellaneous fish and shrimp, thereby reducing feed costs to a limited extent. Or the area has raw materials and land for producing abundant and cheap feed. For example, there are many livestock and poultry farms, animal manure supplies, food processing stations, and scraps are sold around. There is synthetic bait production for frogs nearby, which is more convenient to use. The wild aquaculture industry should consider facilitating the construction of facilities to prevent escape.

The first point is that the venue must be spacious and bright to achieve the desired effect. The second point is that during the breeding process, you should pay attention to the feeding techniques, which are very important. The third point is that you should master the techniques for feeding according to climate changes.

First, every spring, enough frog eggs should be released or enough frog species should be kept. The density of frog eggs in the hatching pond should not be too high, no more than 2,000 per square meter. During the hatching period, attention should be paid to the freshness of the water, timely water changes, scientific feeding, timely prevention of frog diseases, disinfection of the hatching pond, and timely introduction of fresh loaches into the forest after metamorphosis. Although young frogs do not live in water, they must live on moist land.

Breeding forest frogs requires relatively mature technology. It is necessary to choose a quiet environment, dense plants, and close to water. If there are factories, cars, frequent human activities, noisy and severe vibrations, it is not suitable to breed frogs. Choose open areas as breeding farms, and artificially transform the ecological environment. Generally, convenient water sources can effectively control water temperature, dissolved oxygen content and pests, which is conducive to the growth and wintering of forest frogs. Breeding farms need to be able to drain and irrigate freely, which is conducive to the regulation of pond water. There will be no floods in heavy rain weather, and water can be supplied in time in drought.

2. Do I need a license to raise forest frogs? Is it easy to get one? What are the specific procedures? Thank you.

This should be easy.

3. How to prevent and control common diseases of forest frogs?

The breeding of forest frogs requires flexible use of breeding techniques, and the breeding technology is relatively high. Therefore, when raising forest frogs, you must work hard on the usual breeding management methods and techniques. In addition, there is another key, which is to do a good job in disease prevention and control. The following is a detailed introduction to several common diseases and pests in forest frog breeding and their prevention and control.

1. Red Leg Disease

This disease is a common disease of tadpoles, young frogs and adult frogs, and is also known as septicemia. Its pathogen is Aeromonas hydrophila.

Gram-positive and negative bacteria such as Acinetobacter calcoaceticus and non-acid-producing bacteria. This disease can occur all year round, with a faster infection rate and a high mortality rate. The main reasons for this disease are unclean water surface, excessive breeding density, and trauma to the frog body.

1. Symptoms: The affected individuals are generally listless, have weakened ability to move, often hide in water, and are unwilling to live.

The patient did not move, did not eat, had a swollen abdominal cavity, and bloody mucus at the mouth and anus. In the early stage of the disease, the toes of the hind legs were swollen and had blood spots, which quickly spread to all the hind legs. The autopsy showed that there was a lot of ascites in the abdomen, the liver, spleen, and kidneys were swollen and had blood spots, and the stomach and intestines were hematoma and had mucus.

2. Prevention and control methods: Change the water in the fish tank regularly, maintain the water quality, effectively control the stocking density, feed regularly and quantitatively, and isolate and treat the sick individuals in time to prevent the spread; soak the sick frogs in 3% salt for 20 minutes, and disinfect the whole pond with chloramphenicol, with the water concentration reaching 10X10-6, once a day, and continue disinfection for three days. Add sulfadiazine to the bait, add 1-2 grams per kilogram of bait, and continue feeding for three days.

2. Skin fungus disease

1. Cause and symptoms: The pathogen is Saprolegnia, which mainly parasitizes on the damaged parts of the tadpole's epidermal skin. The pathogen invades through the skin wounds and gradually penetrates into the muscles. At the same time, the hyphae of the pathogen grow into cotton-like fungi visible to the adult eye, and slowly spread from the wound to the surrounding areas, causing the tadpoles to move slowly, have difficulty in feeding, and eventually die.

2. Prevention and control methods: Wipe with 10% gentian violet.

3. Bubble Disease

This disease is a common disease of tadpoles. If treated promptly, it is easy to recover. If not treated promptly, it will lead to mass deaths. The main cause of the disease is that the phytoplankton in the water produces a large amount of O2 through photosynthesis under strong sunlight conditions, causing the dissolved O2 in the water to be oversaturated. The tadpoles swallow a large number of bubbles during the mobile feeding process.

1. Symptoms: The intestines of tadpoles with this disease are filled with gas, their bodies swell, and they swim on their backs on the surface of the water. In severe cases, the bubbles in their bodies block their normal blood circulation and the tadpoles die quickly. Autopsy shows intestinal hematoma.

2. Prevention and treatment methods: observe the water in the tadpole pool frequently, and add tap water frequently to prevent too many plants from growing in the water; isolate the individual immediately after the disease, place it in cold water for 1-2 days, and do not feed it with granular feed, so that the body gas pressure gradually balances, so that the bubbles disappear. Then feed a little boiled fermented corn flour, and it will be cured in a few days. You can also add salt to the pool for treatment, usually 15 grams of salt per cubic meter of water.

4. Trichodiniasis

1. Symptoms: After being parasitized by a large number of wheelworms, tadpoles have poor appetite, poor breathing, often swing independently, and move slowly. If not treated in time, many will die. It often occurs in high-density ponds.

2. Prevention and control methods: Reduce the relative density of breeding and expand the space for tadpoles to move around to prevent the disease. In the early stage of the disease, you can use sodium thiosulfate and aluminum sulfate mixture to spray the whole pond, with 0.5 grams of sodium thiosulfate and 0.2 grams of aluminum sulfate per cubic meter of water.

5. Skin rot

When the disease first occurs, the skin on the top of the frog's head becomes dull and has white lines, then the epidermis falls off, exposing the dorsal muscles, which later spread to the entire body and back. Granular protrusions appear in the pupils of the eyes, gradually turning gray-black, and then the entire eye turns white. The frog likes to hide in dark places and often scratches the affected area, causing bleeding.

Prevention and control methods: This disease is mainly caused by long-term feeding of a single bait and lack of vitamins. Therefore, the bait should be diversified; a variety of nutrients should be added to the bait in moderation to ensure the supply of vitamins.

6. Colitis

This disease can occur in tadpoles, young frogs, and adult frogs. It is highly infectious and has a high mortality rate. The disease is more likely to occur when feeding unclean bait. The pathogen is bacteria. If the maggots fed are not disinfected and sterilized properly, it is very easy to cause this disease.

1. Symptoms: Sick frogs usually bow their heads and arch their backs, become thin, show abnormal movements, eat less, and have slow thinking. Tadpoles often float on the surface of the river after becoming ill.

2. Prevention and control methods: Change the water in the fish tank on time to keep the water fresh; do not feed moldy or mildewed bait, and keep it moderate.

Add garlic, ginger slices, berberine, etc. to the bait; analyze and feed the bait on time, quantitatively, and in designated quantities to avoid the disease caused by overeating.

7. Fungal diseases

1. Causes of the disease: The external temperature is low, the temperature is not enough, there is a lack of sunlight, the water surface is not clean, and the relative density of frog eggs is too high, which causes the aflatoxin to multiply.

2. Symptoms: Gray fungi appear around the egg masses of the forest frog, which seriously harms the hatching and survival of the frog eggs and seriously reduces the reproduction rate.

3. Prevention and control methods: (1) Maintain daily cleaning of the egg-laying pool and incubation pool to avoid environmental pollution by Aspergillus flavus. Disinfect and sterilize polluted water with quicklime powder or potassium permanganate solution.

(2) The entire process of transporting frog eggs should be shortened as much as possible, and the relative density should be small when collecting and storing them.

(3) During the egg incubation period, especially in the early stage, sufficient sunlight should be provided. If it rains, place the eggs in a sink or use a white light to directly illuminate the eggs in the room.

You should choose some varieties that are easier to keep in advance, and make sure to ensure the quality of the water. You should change the water regularly. You can also add some tap water or some green plants. If any disease occurs, you should isolate it immediately and treat it with edible salt.

First of all, if you encounter red leg disease, you need to change the water in the tank twice, and then soak the sick frogs with salt. And you must continue to disinfect, so that it can be cured.

The second is that if you encounter skin fungus, you need to apply gentian violet.

The third one is bubble disease. In this case, you should remove all the green plants in the water, and then sprinkle some salt into the water. It will be cured in a few days.

The fourth is that if you have colitis, the treatment method is to add some garlic and coptis chinensis to the feed, and then feed it regularly, which can effectively prevent and treat it.

There are still many diseases that are often seen, so you must change the water during treatment, and choose suitable feed according to its body. Moreover, when the disease occurs, it needs to be isolated so that it will not spread to other frogs. If the disease is more serious, it also needs to be sprayed with medicine.

1. Biological control methods, 2. Control through drugs, 3. Control through varieties, 4. Control through the environment, 5. Preventive measures can be taken based on daily living habits.
