What problems should be paid attention to in raising catfish?

Catfish is also called catfish, it is mainly divided into soil catfish, big mouth catfish, beard catfish and leather beard catfish four kinds. Catfish is a very common fish culture project in our life, it has strong adaptability to the environment, easy to culture and management, and can be cultured in most areas of our country. So what problems do we need to pay attention to when raising catfish? Let's learn more about it.

1. Construction of fish ponds

Before raising catfish, we need to consider the location and construction of fish ponds. In general, we have to choose to build ponds in areas where the water source is adequate, the water quality is pollution-free, and the pool is relatively quiet. Secondly, we carry out the construction of fish ponds according to the topography of the selected fish ponds, and reasonably plan the area of fish ponds according to the scale of culture. The depth of the fish pond is about 1.2 meters. It is necessary to make a good drain and intake pipe in the fish pond. Finally, after the fish pond is built, it should be thoroughly cleaned and disinfected. The disinfection is usually carried out with quicklime, and then fresh water is injected after disinfection, waiting for breeding.

2. Select and release seedlings

There are many catfish fry in the market, but we'd better go to a regular place to choose. When selecting fish fry, observe as much as possible to see if there are any injuries to the appearance of the fry, the activity of the fry and the feeding condition of the fry, and then select the fry that are robust, disease-free and relatively uniform in specification. We should disinfect the fry before releasing the fry, and we should try to raise the fry before releasing the fry. If there is no problem with the trial culture, we can formally release the fry. Finally, it should be noted that when releasing fry, the density should be reasonably controlled, generally 70 or 80 fish fry per square meter, no more than 100 fry at most.

3. Water quality management

In aquaculture, water quality management in fish ponds is very important, so we must pay great attention to it in the process of breeding. First of all, we have to make sure that the water quality in the fish pond is clean and clean, then normally we need to change the water every ten days and a half months or so, but in order to maintain the fertility of the pond, we can keep 30% of the old water each time. In addition, when the catfish often jump out of the water, it means that there is a lack of oxygen in the water, it needs to be injected with salary, and the right amount of oxygenator can be put in. Finally, we can also plant some plants such as duckweed and algae in fish ponds, which can also play a role in purifying water quality.

4. Feeding and management

When we breed catfish, we also need to have professional feeding and management skills. First of all, we need to choose high-quality feed, can not be cheap and ignore the quality of feed. The second is that the identification of feed should be timed, positioned and quantified, which is generally fixed for feeding every morning and afternoon. After eating the catfish, we should clean up the feed residue in time so as not to pollute the water quality. In addition, it is necessary to take good measures to prevent diseases and insect pests so as to avoid serious losses caused by diseases.

Well, that's all for today's editor's sharing. I hope I can help more friends who breed catfish. At the same time, thank you very much for your support and reading. Finally, I wish you all a more smooth breeding process, of course, if you have any questions to consult, you can also leave us a message.
