In the process of culture, the water should be changed in time according to the water quality, usually once every half a month, and only 30% of the pool water should be changed if the water quality is not very dirty. To ensure that the water quality is conducive to the growth of catfish, observe the water quality regularly, yellowish green represents a relatively normal, if found that catfish often jump out of the water. That means that the water quality is too fat and the amount of dissolved oxygen in the water is insufficient. At this time, the water should be changed in time to increase the amount of dissolved oxygen. In case of muggy or rainy weather, we should also pay attention to adding oxygen to the pond to prevent the phenomenon of dead fish with insufficient dissolved oxygen. We can plant some water lotus on the water surface, which can not only regulate the water quality, but also play the role of sunshade.

2. Reasonable feeding

Catfish eating habits are more miscellaneous, and very delicious, will not control their own food intake, so we must grasp the amount of feed when feeding. According to the amount of culture to determine the amount of feed, can not be fed at will, when feeding should be evenly distributed in the pond, follow the principle of a small amount of more feeding. To make catfish full, to prevent some fish do not have enough to eat, the phenomenon of polarization. In the juvenile period, it is necessary to give priority to carnivorous feed, and then gradually change the feed into plant feed as it grows. The feed should be adjusted appropriately according to the growth process and other factors.

Generally, about 25-30 days after stocking, diseased fish will appear a lot of blisters of different sizes on the surface, the fin is red and swollen, and gradually rot, and later a large area of death or even no harvest. Therefore, we must do a good job in prevention and treatment, regular disinfection of ponds, this disease is difficult to treat, can only do a good job of prevention. You can add an appropriate amount of medicine to your daily diet and use quicklime powder or bleach to disinfect the pond.

4. Timely harvest

Control the specification and density of stocking, and then there is a good management method, generally in about 3 months, it is almost time to collect. When collecting, we have to drain all the water in the pond and put a cage with feed in the pond or catch it with a fishing net. When harvesting, it is necessary to catch the big and stay small, let the young fish continue to grow, and re-irrigate the pond and disinfect it after the harvest. Restocking another batch of fry appropriately according to the number of young fish to ensure the catch in the later stage.
