What should be paid attention to in raising catfish?

The area of the pond for catfish culture should be larger, the water should be deeper, the escape prevention facilities should be made around the pond, the water in the pond should be changed regularly in the process of culture, and some highly suitable aquatic plants such as water lotus can be planted in the pond, which can not only purify the water quality but also provide sunshade for catfish, feed reasonably, ensure balanced nutrition, prevent diseases, and disinfect the pond regularly. The catfish was harvested by the mode of rotation.

1. Selection of fish fry in pond

The pond area of breeding catfish had better be a little larger, the water level should not be too shallow, in order to provide a suitable growth environment for catfish, the height of aquatic plants in the pond should be appropriate, neither too long nor too short, and the weeds in the pond should be cleaned up regularly in the process of culture. anti-escape facilities should be made around the pond to prevent catfish from escaping.

2. Change water regularly

The good water quality will directly affect the growth of catfish, and the water quality in the pond should be observed at any time during the culture process. If the water quality becomes worse, the water should be changed immediately, generally every 15 days or so. If the water quality is good, you only need to replace 30% of the water.

The water color is yellowish green is a normal water quality, if the catfish often jump out of the water is due to the water quality is too fat, the oxygen content in the water is too low, the pool water needs to be replaced immediately to improve the water quality. On muggy, cloudy and rainy days, oxygen should be added to the pond at the right time to avoid the death of fish due to lack of oxygen. Some aquatic plants such as water lotus can be planted in the pond, which can not only improve the water quality but also provide shade for catfish.

3. Feeding should be reasonable.

In the process of breeding, feeding should be reasonable, and the feed fed each time should not be too much to avoid esophageal obstruction of catfish eating too much. Catfish in the seedling stage, the feed should be chopped so that the young fish can be fed and digested; at the age of 2 months, granular feed can be added, and some protein can be added to the feed to ensure nutritional balance.

4. Disease prevention

The disease resistance of catfish is not very strong, it is easy to get sick, and the most common one is abusive disease. generally, fish fry may be infected in less than a month, showing that there are many blisters of different sizes on the fry, and the fin is red and swollen. Then the catfish slowly rots until it dies.

In the process of breeding, regularly sprinkle a certain proportion of quicklime or bleach into the pond to disinfect the pond, and the feed can be mixed with some disease-resistant drugs.

5. Catch and harvest

Pay attention to the specification and density of fish fry. Generally, you can catch fish in about 100 days. Release the water in the pond before fishing, put some cages filled with feed into the pond or directly use fishing nets to catch fish. When fishing, it should be noted that the catfish with smaller sizes need to continue to be cultured in the pond, and after reaching the listed specifications, they will be fished and sold. After fishing, the water in the pond will be restored to its original position and disinfected once.
