2. What are the management measures for catfish breeding?
1. Change water regularly
During the breeding process, water should be changed in time according to water quality conditions. Usually the frequency of water changes is once every half month. If the water is not very dirty, only 30% of the pond water needs to be changed. Ensuring water quality is beneficial to the growth of catfish. Observe water quality conditions regularly. Yellow-green indicates relatively normal conditions. If catfish are often found jumping out of the water,
that means the water is too nutrient-rich, and the dissolved oxygen content in the water is insufficient. At this time, water should be changed in time to increase the dissolved oxygen content. In stuffy or rainy weather, attention should also be paid to increasing oxygen in the pond to prevent fish deaths caused by insufficient dissolved oxygen. Some water hyacinths can be planted on the water surface, which can both regulate water quality and provide shade.
2. Reasonable feeding
Catfish have omnivorous feeding habits and are very greedy. They do not control their own food intake, so when feeding feed, we must control the feeding amount well. Determine the feeding amount according to the number of fish being farmed. Do not feed randomly. When feeding, spread the feed evenly in the pond and follow the principle of small amounts and frequent feeding.
The catfish should be allowed to eat their fill, to prevent some fish from not eating enough and the emergence of polarization. During the juvenile stage, carnivorous feed should be the main feed, and then as they grow, the feed should gradually be changed to plant-based feed. Adjust the feed appropriately according to the growth process and various other factors.
3. Disease control
Various diseases will appear when farming catfish, among which ulcer disease is the most serious. It usually appears around 25-30 days after the fish fry are stocked. Sick fish will show many blisters of different sizes on the surface, the fins will be red and swollen, and gradually rot, followed by large-scale death in the later stage or even total loss. Therefore, we must do a good job in prevention and control, and regularly disinfect the pond. This disease is difficult to treat, so only preventive work can be done well. An appropriate amount of medicine can be added to daily bait, and quicklime powder or bleaching powder can be used to disinfect the pond.
4. Timely harvest
Control the size and density of stocking well, and then have a good management method. Generally, after about 3 months, it is almost time to harvest. When harvesting, first drain all the water from the pond, then place cages with feed in the pond or use fishing nets to catch them. When harvesting, catch the large ones and leave the small ones so that the juvenile fish can continue to grow. After harvesting, refill the pond with water and disinfect it. According to the number of juvenile fish, appropriately stock another batch of fry to ensure the later harvest volume.
