Several common culture models of Pelteobagrus fulvidraco

Pelteobagrus fulvidraco, also known as yellowbone fish, is an omnivorous fish, mainly feeding on benthos, small fish, shrimp, aquatic insects and some invertebrates and plankton. Pelteobagrus fulvidraco belongs to warm water fish and has strong adaptability to environment. At present, it is mainly produced in some river basins of Yangtze River, Yellow River, Pearl River, Heilongjiang River and Liaoning Province in China. So what are the common farming models of yellow catfish now? Let's take a look.

1. Yellow catfish pond main culture

Pelteobagrus fulvidraco pond culture is the most traditional culture mode, but also the most commonly used in our lives to a fish culture mode. The pond is mainly used to raise Pelteobagrus fulvidraco. The water depth is generally more than 1.5 meters. The silt at the bottom of the pond should not be too thick. Before stocking, it should be disinfected with quicklime. The specification of Pelteobagrus fulvidraco stocking is about 10 to 15 centimeters. The breeding of yellow catfish per mu is about 3,000 to 4,500 fish, and a proper amount of bighead carp, bass, silver carp, etc. are bred to regulate the water quality, so that the income of breeding will be higher.

2. Mixed culture of Pelteobagrus fulvidraco and Trionyx sinensis

The fish and turtle polyculture technology of Pelteobagrus fulvidraco is actually to use the pond main culture technology, in the process of culture, add turtle that can grow together with Pelteobagrus fulvidraco to culture. We generally use Chinese soft-shelled turtle and yellow catfish for mixed culture. Generally, when the water temperature is about 20 degrees Celsius, Chinese soft-shelled turtle is put in. The number of Chinese soft-shelled turtle is about 200, while the number of river crab is about 600 to 800. It is necessary to feed yellow catfish twice a day. At the same time, it is necessary to feed Chinese soft-shelled turtle with high-protein feed. In this way, the water body is fully utilized, and the economic benefit is greatly improved.

3. Yellow catfish and crab breeding

The economic benefit of fish and crab polyculture model of Pelteobagrus fulvidraco is also very good at present. And we are in the mixed culture of fish and crab, generally with crab and yellow catfish mixed culture. River crabs are generally bred in April of each year, according to 600 to 800 river crabs with specifications of about 30 to 40 grams per mu. In the breeding process, about 50 silver carp need to be stocked, and the feed of river crab is mainly put in the feeding process, and a proper amount of feed of yellow catfish can be fed, which can reduce the risk of breeding and reduce the breeding cost.

4. Intercropping Pelteobagrus fulvidraco in rice field

Rice field interbreeding technology is actually a very practical ecological breeding model at present, such as fish, shrimp, crab, eel, loach and other aquatic products can adopt rice field interbreeding model. The rice field interbreeding of Pelteobagrus fulvidraco is also the same, but the specifications are generally about 8 to 10 cm. Two thousand to three thousand yellow catfish can be raised per mu, and rice can also be harvested, but attention should be paid to the use of pesticides and chemical fertilizers, try not to use pesticides and chemical fertilizers.

5. Mixed culture of yellow catfish and shrimp

The fish and shrimp polyculture technology of Pelteobagrus fulvidraco is very profitable at present, because the market price of shrimp is relatively high now. In general, the mixed culture of fish and shrimp of Pelteobagrus fulvidraco adopts green shrimp or South American white shrimp. Before breeding, the pond should be thoroughly disinfected. Then, the size of Pelteobagrus fulvidraco is about two or three centimeters, and 3,000 fish can be bred per mu. and the number of shrimp and penaeus vannamei stocked is about 60,000 about one centimeter. When feeding, pay attention to feeding shrimp feed first, and then feed yellow catfish feed.

The above are the most common breeding modes of Pelteobagrus fulvidraco at present, among which there is also a more common breeding mode, that is, cage breeding. This breeding mode is introduced separately. If you are interested, you can pay attention to us or leave a message to Xiaobian.
