Qingjiang fish and catfish are both freshwater fish with very high nutritional value. They are not only rich in protein, but also low in fat, which can bring many benefits to human body. If you want to distinguish Qingjiang fish from catfish, you can judge it by body shape, body color, head and tail, etc. If you want to raise catfish at home, you must master the method. It is very important to release them on two levels. Usually, it can be fed reasonably, and at the same time, it should be caught in turn and raised separately to prevent small fish from being robbed by big fish.

First, the difference between Qingjiang fish and catfish

Qingjiang fish's body looks a little flat, and its length is similar to that of yellow croaker, but catfish is round and weighs a lot, and some of them can even be as high as several thousand kilograms. The color distribution of Qingjiang fish is relatively uniform, with scales on its body, while catfish is dark brown, but there is some white in its abdomen and no scales on its body. Qingjiang fish's head is much smaller than catfish's and its mouth is a little flat. Catfish have many long beards. Besides, the tail of Qingjiang fish is not only forked but also very short, which is somewhat similar to the shape of scissors.

Second, the catfish culture method

Catfish fry have weak resistance. If they are raised directly, it will not only pollute the water quality, but also be difficult to eat the fed food. Therefore, they need to be intensively raised in small ponds first, and then put into large ponds for free-range, which can help them grow rapidly. In the process of feeding, it is very necessary to master the food intake, and the food should be evenly distributed, eat less and eat more meals to prevent the weight polarization of catfish. Finally, because the big fish will grab food, if they are fed in a unified way, it is easy to cause the phenomenon that the small fish can't eat food, so it is necessary to raise the big and small fish in separate ponds to make them grow in a balanced way.

Catfish has poor cold tolerance, so we must pay attention to keep him warm during the breeding process in winter. In fact, Qingjiang fish and catfish look very different. As long as we master some of their characteristics, it is very easy to distinguish them. Moreover, when raising catfish, as long as the method is correct, their survival rate is high and their reproductive ability is strong.
