1 Pre-reserve preparatory work The frog cultivation is carried out in abandoned breeding farms and the facilities are sufficient for the cultivation of beautiful frogs. However, it is necessary to inspect the entire farm's intake and drainage systems, shading facilities, pool bottoms and pool walls to ensure that they are intact and repaired in a timely manner. To remove debris from the pool and sterilize h Liquefy or bleaching powder clearing pond is available 10 days before stocking. The dosage is 400 grams of quick lime and 50 grams of bleaching powder per cubic meter of water body. Quicklime and bleaching powder disappeared after 8 days and 3 days, respectively, and then he was washed in water 2 or 3 times, and new water was added to be released.
2 American frog breeding
2.1 The artificial feeding of bait began after 6 days of hatching. It is better to use cooked egg yolk as bait. The egg yolk was smashed with a dense iron sieve and thrown directly into the pool. At the beginning stage, feeding is conducted within a relatively large range. Afterwards, the feeding point is gradually reduced to feeding at a fixed point, 1/2 egg yolk is fed for each kilogram, each time is fed in the morning and at night; after feeding for 5 to 6 days, it can be changed. Feed cooked fish or puffed granule bait. After 25 days of hatching, some aquatic animals can be cultivated as supplementary diets to speed up their growth.
2.2 The young frog stage This stage can be used as a feed for fresh animals, such as sterile fly maggots, clams, small fish, shrimp, etc., once every morning and evening. Can also be fed on an extruded granule feed bait and allowed to feed. The feed could not be eaten on the same day and should be promptly removed to avoid damaging the water quality. When the frog grows to 2Dog, it can be turned into a frog breeding pond.
2.3 Adult frogs at the stage of frogs are mainly extruded prills. When feeding, feed can be fed on a feed table and fed once a day in the morning, in the evening, and then in the evening. In order to increase the source of new live bait, a black light can be hung in the frog pond to attract light-catching insects and be preyed by the baby: Artificial quail and yellow mealworms can also be cultured and put into the frog pond after it grows.
3 daily management
3.1 The patrol ponds will be patrol once every morning, evening and evening. Observe the changes in water quality, check the frog's growth, activities, and feeding conditions, whether it is normal, whether there are diseases and residual baits, especially during the hot season, heavy rain, and find out the situation in a timely manner.
3.2 Water Change American frogs do not require high quality water during growth and development. They do not need to change water every day, as long as they keep the water fresh and not spoil. In general, in the pupa stage, change the water every 8-10 days, and change the water every 6-7 days in summer; in the young frog stage, the more excrement it excretes due to the increasing food intake. The pool water is changed every 3-4 days; in the frog stage, it is necessary to change the water every 2-3 days.
3.3 Anti-escape and anti-enemies Although the frog is not good at jumping, it must not underestimate its ability to escape. Especially in the frog stage, pool water should not be added too deep. It can be about 30cm from the pool. American frogs have a lot of predators and many animals can hunt on them, especially crickets. Their bodies are hypertrophic and their activity is poor. They are more vulnerable to attacks by animals such as snakes, rats, and birds (such as kingfishers and cranes). Therefore, during the process of patrolling the pond. It is found that the enemy should be promptly removed, and an anti-adversary device should be installed at the entrance and exit where the enemy is easily invaded.
3.4 To prevent the killing, and to divide the pool in time, according to their growth, divide the pool every 20 days or so. In the frog and adult frog stage, there is a difference in growth between individuals, and they are of different sizes after being raised for a period of time. In the same pool, because of the existence of a small frog that eats small frogs, frogs of different sizes should be stocked in separate pools. Reduce unnecessary losses.
3.5 Simulating Wild Eco-environment Increase water lilies in the pond to create a good ecological environment and allow it to have a good habitat. Water Lilies can also absorb organic matter in water and have the effect of purifying water.
4 disease prevention and control of frog disease more, production should be based on prevention. In the usual feeding, pay attention to environmental hygiene, fresh food, nutritional balance, appropriate feeding of preventive drugs, found that water quality is poor or there is disease, make a diagnosis as soon as possible, and take effective treatment measures in time. Beauty frog common diseases are as follows.
4.1 common stage disease prevention and control a. Bubble disease: Symptoms are sick, floating on the surface of the water, the body loses balance, some uneasy rests, the abdomen expands, the intestine is filled with air bubbles and edema.
Treatment: Change the water in the affected pool promptly. After changing the water, use a 20% solution of magnesium sulfate for 48 hours and change the water. 2 He used 800mg/L saline water Quanxi Han sprinkle. 3 After mashing, the feed was soaked in water and 1.5 g/1000 yeast tablets were added for 3 days. Bacterial bacterial gill disease: Symptoms are pale, rotten, and attached sludge and mucus that floats on the surface of the water and are slow to move. Treatment: Sprinkle 1mg/L bleach or 2mg/L calcined water.
b. Bacterial enteritis: Symptoms include illness, loss of appetite, slow swimming, gastrointestinal congestion, inflammation, congestion around the anus, and swelling. Treatment: Clean and sterilize the food table, use 2mg/L bleach to disinfect the pool water, once a day, and oxytetracycline 1.25g/1000 tails, divided into 2 parts and used for 3 days.
c. Fulminant septicemia: Symptoms include severe hemorrhage around the pharynx, abdomen, anus, etc., and some turning around on the surface of the water. The eyeballs are congested and prominent. Treatment: The disease is caused by dehydration of the pool water, and the web is used to concentrate the alfalfa at a high density. Each 10,000 algae is soaked with 500,000 international units of penicillin for half an hour.
4.2 Adult stage prevention and treatment of common diseases a. Gastroenteritis: Symptoms of the diseased frog are initially restless and muddy, followed by inability to beat, unresponsive, lying on the edge of the pool, stretching the legs and closing the eyes, and swelling of the anus. A necropsy patient frog, no food in the intestine, congestion in the bowel wall, inflammation.
Treatment: 1 Use 2mg/L bleaching powder to disinfect feedstuffs, feedstuffs, and pool water, and feed yeast tablets 20 to 30g/Kg feed twice daily for 3 days. 2 with soil toxin feed, 0.28/kg body weight per day, fed 3 times, 3 days for a course of treatment.
b Red-legged disease: Symptoms include loss of luster on the head, back, and extremities of the diseased frog, and the appearance of leukoplakia, severe epidermis shedding and rot: frog leg medial, femoral and abdominal hypodermic spotting, red, erythema-like, Muscular punctate congestion, and some intestinal congestion.
Treatment: 1 Disinfect the pool bowl with 1.5mg/L copper sulfate Quanchiposa, 2mg/L bleach solution or 30mg/L lime. 2 isolation disease frog, soaked with 0.1 ~ 0 15 salt water. 3 days is a course of treatment. 2 Every day, every kilos of frogs add oxytetracycline 0.2g in the feed and feed it in two batches. 3 days for a course of treatment.
c. Abdominal distension disease: The symptoms are abdominal distension. The gas in the abdomen becomes blue-purple and the gastrointestine wall is red and congested. The inner food is internal and the internal organs are squeezed to the back to varying degrees.
Treatment: chloramphenicol, erythromycin, gentamicin, or fluoropain may be used for treatment.
d fulminant bacterial disease;
Symptoms of diseased frogs often colonize around the pond and pool corners, low-pitched ground, no feeding, dry and dull skin, abdominal swelling, ascites in the abdominal cavity. Treatment: 1 per kilogram of water plus 160,000 IO penicillin and 40,000 IO streptomycin soak 10min. 2 Oral administration with gentamicin or fluoropain.
