We often hear this saying: pond catfish can not eat, catfish can eat. So is that really the case? First of all, let's find out what kind of fish the pond mackerel is.
Pond flounder
On the mainland, there are two main types of pond catfish, one is the native pond catfish, also known as the bearded catfish, and the other is the Egyptian pond catfish, also known as the leather beard catfish. Remember its main features about the native pond carp: it has eight beards, four above the lips and four below, and is also small. Just like on the pictures. The beard characteristics of the Egyptian pond flounder are the same as those of the native pond mackerel, except that the Egyptian pond flounder is blackened, large, fast-growing, has extremely low water quality requirements, and can survive in a low-oxygen environment, so it can also be found in some heavily polluted waters.
Leather-bearded catfish
They eat basically everything under the water, and they are omnivorous fish, so many people see the environment in which it lives, and they think that this fish is very dirty and cannot be eaten. In fact, there is a certain truth to this, in the wild environment, you can not guarantee its water quality and what it eats, so it may have accumulated some toxins in its body, and its own flesh quality is not good. However, artificial breeding can be eaten, we don't have to worry, if you want to eat, go to the market that has been formally tested to buy it can be eaten with confidence. In short, do not care what kind of catfish, wild or do not eat, wild animals will more or less carry some parasites.
It is worth noting that catfish is a hair object, there are rheumatic osteomaterial arthritis, chronic diseases, sore skin suppuration infection and so on, after eating it may make the disease more and more serious, which should also be one of the reasons why the pond mackerel can not eat it.
Earth catfish
So, what is the difference between the pond catfish and the catfish we usually see? What we often refer to is a large-mouth catfish, also called earth catfish, which is very different from the pond catfish, it has only four whiskers, two upper and lower lips, and grows slowly. It tastes good compared to pond mackerel, and it does not have a fishy taste like pond mackerel. But it is much more expensive than the price of pond carp, so there are many people who take pond fish to pretend to be earth catfish to sell, everyone must polish their eyes, see what kind it is, and then decide whether to buy it.
