Catfish and pond mud raised by farmers are not a kind of fish, and they are different in many ways. First of all, they belong to different families. Secondly, the two kinds of fish are different in appearance. Besides, their meat tastes and values are different. In addition, pond sludge has very strong adaptability and rapid growth rate.

Many people confuse catfish with pond mud, but they are actually two different species, not a kind of fish, and the difference between them is still very big.

First of all, they belong to different families. Although pond fish and catfish are catfish-shaped, their families and genera are different. Pond fish belongs to Silurus of Silurus, and catfish belongs to Silurus of Silurus. In a sense, they have a certain genetic relationship, but because of their different families and genera, they are still very different and cannot be confused.

Secondly, the two kinds of fish are different in appearance. The number of beards is different. Both pond crabs and catfish have beards on their mouths, but even beards are different. Their numbers are different. There are four pairs of beards on the mouth of the pond dolphin, and the total number of beards is eight. Catfish have only two pairs of beards on their mouths, and the total number of beards is four. This can be used as a feature to distinguish them. The fins of these two kinds of fish are also different. There are very obvious fins on the back of pond fish, but no fins on the back of catfish. Moreover, the mouth of catfish is relatively large, and the mouth size of pond fish is normal. Moreover, the pond fish is very big and black all over. Catfish is yellow and relatively small.

Besides, their meat tastes and values are different. Both pond fish and catfish can be used, but the meat quality of pond fish is poor and it has a heavy smell. Catfish is more delicate and tastes better. Relatively speaking, catfish has higher nutritional value. Because of their higher taste and nutritional value, their prices are also higher.

In addition, pond sludge has very strong adaptability and rapid growth rate. This kind of fish does not require high water quality, and can grow even in sewage, and the growth rate is particularly fast, which can grow to more than 10 kg. Catfish have higher requirements for water quality. They like clean places with running water, mainly in the wild, and grow slowly, so it is difficult to exceed one catty.

These are a series of differences between catfish and pond mud.
