Catfish is a kind of common fish. They can be cultured artificially. In addition, they can also live in fresh water such as rivers and lakes in the wild. Their distribution range is very wide all over the world. Relatively speaking, the growth rate of catfish is relatively fast, and their size is relatively large. Of course, not all cases of catfish growth rate is very fast, their growth rate will be affected by environmental factors, such as water temperature, water quality and so on. In addition, their growth rate will also be affected by food, different food contains different effects, so the promotion of their growth and development is also different.
As mentioned above, the growth rate of catfish is relatively fast, especially in the case of suitable environment and sufficient food. Generally speaking, catfish can grow 1-4 kilograms a year. Specifically, the growth rate of catfish is different under different conditions. For example, in the case of artificial breeding, we can artificially regulate the surrounding water temperature, water quality and other conditions, but also provide a lot of nutritious food, so the growth rate of catfish will be faster, can grow three or four kilograms a year. The growth rate of wild catfish may be slower due to various environmental factors.
In addition, the growth rate of catfish is different in different growth stages. In farmed catfish, the growth rate is relatively fast in the second and third years, and then slows down. Of course, catfish may be sold directly after several years of cultivation, at which time they can not continue to grow.
