Culture techniques of bullfrog

Bullfrog is a kind of edible frog, large in size, fresh and tender in meat, and very rich in nutrients. Eating it is very good for people's health and is deeply loved by people. Now the bullfrog breeding industry has formed a trend that it is getting hotter and hotter year by year. So is bullfrog easy to raise? Next Shuai Shuai will tell you what conditions and how to breed bullfrogs.

How to raise young frogs

The young frog here does not refer to the bullfrog in the tadpole period, but refers to the little bullfrog whose body has been separated from the tadpole period for nearly two months. At this time, the little bullfrog weighs only about 20 grams. At this time, when we feed the bullfrog, the feed is mainly live insects, and we can prepare some earthworms and small fish. In addition, young frogs have a bad habit of not eating dead things. So in order to make the young frogs adapt to the habit of eating dead things and slowly change them, we can first put the dead things on the feed plate, and then put some living things on the feed plate, such as preparing some live Loach. This can make the frog have the illusion that it is all alive, and then slowly change it. The stocking capacity of young frogs can be 100 per square meter, and if they are more than 40 days old, they can put 80 per square meter.

2. The main points of bullfrog culture

Generally speaking, the gonads of young frogs mature after being raised for a year, and the standard weight of an adult young frog can reach more than 250g, which can be put on the market after reaching this standard. Adult young frogs generally feed on small insects and aquatic animals, such as earthworms and shrimps. If the young frogs are domesticated, they can also change their feeding habits. The internal organs of domestic animals such as silkworm pupae can be fed to them as feed. Because bullfrogs are nocturnal animals, we try our best to feed them in the evening, usually in the evening. It is necessary to feed enough at one time, because if the feed is not enough, it will scramble for food and kill each other, and the feed should not be too single, otherwise it will lead to malnutrition and vitamin deficiency. Once suffering from this kind of disease, it is easy to cause bullfrog skin disease.

III. Three methods of bullfrog culture

1. Intensive culture

This way is the most used, intensive farming is a high-density breeding method, which can not only breed bullfrogs alone, but also breed bullfrogs and fish together. When choosing a breeding site, the water depth of the frog pond is about one meter. Some aquatic plants can be placed in the frog pond so that it can inhabit it, and some lotus leaves can be planted in the frog pond. The general stocking density is 2000-3000 per hectare.

2. Semi-open frog farming

Semi-open frog farming is to put young frogs on a larger surface of the water, with natural bait as the main feed and artificial feed as a supplement.

3. Exile culture

Bullfrogs are put on thousands of acres of water, which is called exile farming, but only if there is a lot of natural bait and aquatic plants in this sleep.

IV. matters needing attention in bullfrog culture

1. Bullfrog is a kind of animal that is very sensitive to temperature. if the surrounding temperature is lower than 10 degrees, it will automatically go into hibernation, and if the temperature is below zero, the bullfrog will freeze to death directly. in addition, if the temperature is too high, it will also cause the possibility of heat death. the best temperature for growth and development of bullfrogs is 25-30 degrees.

2. Humidity also has an effect on bullfrogs, because the skin of bullfrogs is completely exposed and there is no protective tissue, so if the growth environment of bullfrogs is too dry, it will affect its growth. If it is directly exposed to the sun for half an hour, it can directly kill the bullfrog.

The above is the breeding technology of bullfrog, have you learned it? Another thing to be careful is not to expose the bullfrog in dry air. If it lasts more than 20 hours, it will die. If you want to know more related information, please continue to follow the pro-agriculture network!
