What are the precautions for yellow catfish farming?
The yellow catfish is a very popular fish in China. It is mainly distributed in regions such as Hubei, Hunan, Guangdong and Guangxi, and the yellow catfish has very high nutritional value. Nowadays, the farming area of yellow catfish is also growing larger and larger, and it has great room for development. However, when farming yellow catfish, there are many things we need to pay attention to. Today, the editor brings you the precautions for yellow catfish farming. Let's take a look below!
1. Feed selection
The quality of the feed has a very great impact on the growth of yellow catfish. It directly determines the growth capacity and yield of yellow catfish. Good-quality feed can effectively increase the appetite of yellow catfish, advance the time yellow catfish are harvested from the pond, shorten the growth cycle, and prevent some unnecessary losses caused by too long a farming period. Therefore, when farming, we must pay attention to choosing good feed, and must not feed feed that has pests or diseases or has been dead for too long. And when feeding, the feed should be disinfected to strengthen the physique of yellow catfish and improve farming efficiency.
2. Adjust the feeding amount
The feeding amount is also very important for the growth of yellow catfish. The feed demand of yellow catfish changes as it grows, so when feeding we should carry out quantitative management of the feed. When feeding, we must not only ensure the feed has good palatability, but also ensure the quality of the feed. With the goal of reducing the pressure on the liver, when feeding, attention should be paid to concentrating most of the feed in the middle and late stages of yellow catfish. Attention should also be paid to reasonably adjusting the feeding amount according to various factors such as climate, water quality and feeding conditions, to prevent waste caused by overfeeding.
3. Dissolved oxygen in the water
The dissolved oxygen content in the water is also an aspect we need to pay attention to when farming yellow catfish. Especially in high-temperature seasons such as summer, the dissolved oxygen content in the pond is often reduced due to reasons such as overstocking and large food intake, affecting the growth of yellow catfish. So when farming, we should prepare aeration equipment. When yellow catfish surface for air and other such situations occur, it means the dissolved oxygen is insufficient, and at this time aeration should be carried out promptly. Finally, we should often observe the growth of yellow catfish to create a good growing environment for them.
4. Water quality management
When farming yellow catfish, water quality management is also an indispensable management task. This is because during farming, adverse phenomena such as excessive nitrite content often occur in the water body. The main reason is caused by feeding too much feed and not changing the water for a long time. So when farming, we should change the water regularly and use biological agents to improve the water body, reducing the content of harmful substances in the water body. And we can appropriately plant plants such as water hyacinth and aquatic plants in the pond. This can not only absorb harmful substances in the water body, but also provide a habitat for yellow catfish.
The above is a brief introduction to the precautions for yellow catfish farming. These precautions for yellow catfish farming are also the management tasks we need to do well when farming. Only by doing these management tasks well can we effectively increase yield and expand farming efficiency. That is all for today's introduction.
