What is the difference between catfish and catfish? A quick guide to telling them apart
The catfish is a common fish in ditches, and like the catfish, it has 4 barbels on its mouth, so many people think they are two different fish. So what is the difference between catfish and catfish?
1. What is the difference between catfish and catfish?
There is no difference between catfish and catfish; the two are actually the same species, also known as sheatfish, catfish, sticky fish, pond catfish, and live-bearing fish. It has a total of 4 barbels on its mouth, long on top and short below, and is mostly wild. Because it is fast and does not demand much of water quality, it can also be farmed artificially.
2. Why is the catfish said to be the dirtiest fish in the world?
1. The farming environment of the catfish is extremely harsh; it grows in stinking ditches and eats rotting garbage, making it the dirtiest fish in the world. At first glance, it has no scales all over its body, and its surface is covered with a lot of slime, so it does indeed look rather dirty, but this does not affect its being served as a delicacy on the public dining table.
2. Professor Tan Hongxin of the College of Fisheries and Life Science at Shanghai Ocean University explains that the catfish has especially strong survival ability and can adapt to murky water, fertilized water, and dirty water, but if there is too much dirty material, it will lead to a high ammonia nitrogen content in the water, worsening the water environment and affecting the growth of the catfish.
3. The catfish likes to grow in the middle and lower layers of lakes and fish ponds. It may look as if it is not very hygienic, but it is highly tolerant and can absorb the nutrients it needs from harsh water bodies, and then through metabolic processes such as digestion, filtration, and excretion, by the time it is served on the dining table it has already “been reborn”. It is just like how vegetables are also given farmyard manure during growth, but in the end none of that waste remains on them.
Overall, the catfish is the sheatfish; there is no difference between the two, it is just that they are called by different names.
