Detailed Explanation of Bullfrog Farming Techniques and Key Methods
The bullfrog is an edible frog with a large body, tender and fresh meat, and it is also very rich in nutrients. Eating it is very good for people's health, and it is deeply loved by people. Nowadays, bullfrog farming has already formed a trend, becoming more and more popular year by year. So, are bullfrogs easy to raise? Below, Shuaishuai will tell everyone what conditions are needed for bullfrog farming and how to farm them!
I. How to Raise Young Frogs
The young frogs referred to here are not bullfrogs in the tadpole stage, but small bullfrogs whose bodies have already left the tadpole stage for about two months. At this time, the young bullfrogs weigh only about 20 grams. If we feed the bullfrogs at this time, the feed is mainly live insects. You can prepare some earthworms and small fish, etc. In addition, young frogs have a bad habit, which is that they do not eat dead things. So, in order to let the young frogs adapt to the habit of eating dead things and let them slowly change over, we can first put dead things in the feed tray before feeding, and then put some live things into the feed tray, such as preparing a few live loaches. This can create a certain illusion for the frogs, making them think they are all live things, and then they will slowly change over. The stocking density of young frogs can be 100 per square meter. If the bullfrogs are over forty days old, then 80 per square meter can be stocked.
II. Key Points of Bullfrog Farming
Generally, after young bullfrogs are raised for one year, their gonads become mature. The standard weight of an adult young bullfrog can reach more than 250 g. Generally, once it reaches this standard, it can be sold on the market. Adult young bullfrogs generally feed on small insects and aquatic animals. Earthworms and small shrimp, etc. can all be its food. If the young bullfrogs have been domesticated with feed, they can also change their feeding habits. Silkworm pupae and the internal organs of livestock, etc. can be given to them as feed. Because bullfrogs hide by day and come out at night, they are nocturnal animals, so our feeding time should be as much as possible at night. Generally, feeding is done in the evening. When feeding, feed enough at one time, because if there is not enough feed, they will snatch food from each other and kill each other. Also, the feed should not be too monotonous, otherwise it will cause malnutrition and lead to vitamin deficiency. Once they suffer from this kind of disease, it can easily cause skin diseases in bullfrogs.
III. Three Methods of Bullfrog Farming
1. Intensive farming
This method is the most commonly used. Intensive farming is a high-density farming method. Bullfrogs can be farmed alone, or bullfrogs and fish can be farmed together. When choosing a farming site, the water depth of the frog pond is best at about one meter. Some aquatic plants can be placed in the frog pond so that they can perch on them. Some lotus leaves can be planted in the frog pond. Generally, the stocking density is 2000-3000 per hectare.
2. Semi-open frog farming
Semi-open frog farming means releasing young frogs into a larger body of water, mainly using natural bait as feed and artificial feed as a supplement.
3. Free-range farming
Releasing bullfrogs into thousands or tens of thousands of mu of water surface is free-range farming, but the premise is that this water surface should have a large amount of natural bait and aquatic plants.
IV. Precautions for Bullfrog Farming
1. Bullfrogs are very sensitive to temperature. If the surrounding temperature is below ten degrees, they will automatically enter hibernation. If the temperature is below zero, the bullfrogs will directly freeze to death. In addition, if the temperature is too high, it can also cause the possibility of death from heat. The optimal growth and development temperature for bullfrogs is 25-30 degrees.
2. Humidity also has an effect on bullfrogs, because the skin of bullfrogs is completely exposed outside without any protective tissue, so if the growing environment is too dry, it will affect their growth. If they are directly exposed to the sun for half an hour, the bullfrogs can be directly killed by sun exposure.
The above is the bullfrog farming technique. Have you all learned it? In addition, note that bullfrogs should not be exposed to dry air. If it exceeds twenty hours, they will die. To learn more related information, please continue to follow Qinnong Network!
