Are pond fish, horned fish and catfish the same? How to tell the difference between them? Which is more nutritious?

In life, many people like to eat catfish, think it is tender meat, no thorns, the price is also cheap. However, many people can't tell the difference between pond fish, horned fish and catfish. So, are these three kinds of fish the same? Which is more nutritious?

1. Tangxiang

There are mainly two kinds of ponds in our country. one is the Egyptian pond, which is an economic species introduced by China from Africa, usually called the moustache catfish, also known as the leatherbeard catfish, which has a strong ability to reproduce and adapt, and grows fast; one is a native catfish, commonly known as pond fish and pond horn fish. The meat is fresh and tender, with good taste and high nutritional value, so it is a delicacy that people like very much. However, wild fish grow slowly and generally weigh no more than one jin.

1. The pond of Egypt

The Egyptian pond, the scientific name of the Egyptian moustache catfish, is very different from the native catfish commonly seen by everyone. The main reason is that the Egyptian pond louse has a large dorsal fin on the back and eight beards (four pairs). It is generally black in color.

2. Local pond

The body pond fish is generally called small mouth catfish, catfish, soil catfish, pond fish. What is different from the Egyptian pond is that the back is only a handful of dorsal fins, and the beard has only two pairs of four maxillary whiskers that can reach the end of the pectoral fin, and the lower jaw is shorter. The local ponds are generally small, and the body color is mostly light yellow or khaki.

Second, catfish

Catfish is the name of a species, there are many kinds of catfish, including catfish, big mouth catfish, sea catfish, moustache catfish is commonly known as pond catfish, big mouth catfish is what we call six-bearded catfish, river catfish, fork mouth catfish and so on. Sea catfish is a catfish that lives in the ocean, not necessarily a catfish, but because of its similar appearance, it is generally called sea catfish.

1. Big-mouth catfish

Looks like the local catfish is no different, but the mouth is very big, meat quality is also relatively common, generally speaking, black-hearted hotels like to use this kind of catfish pit do not understand diners. The only difference is that the big-mouth catfish grows rapidly, the individual is much larger than the catfish, and can be distinguished by the shape of the mouth.

2. Sea catfish

The catfish living in the sea are classified as sea catfish in species, which are more common in the East China Sea and South China Sea, with fishy taste and poor meat quality, and are generally processed as salted dried products or braised in soy sauce.

After some understanding, many people still can not distinguish between catfish and pond fish, in fact, it is quite simple to say how to understand whether it is a pond fish or a catfish.

First of all, it can be easily distinguished from the color and shape. The body of the pond fish is basically black and there are eight whiskers that like to eat rotten food, while the catfish has yellow body color and only two moustaches, and the catfish only has fins below and there are fish fins on and off the pond fish.

Secondly, their living conditions are also very different. Tang Fang likes to live in sewage with strong survivability and a wide range of food types, and catfish in captivity can be said to eat whatever they can eat. Catfish, on the other hand, prefer to live in clean and flowing waters, afraid of light, like to hunt at night, like to live in caves when winter comes, and have three characteristics: big mouth, big head and big belly.

After reading it, do you think it is very simple? as for which one is more nutritious, of course it is catfish. It can be seen from their prices that wild catfish have been sold for 40 yuan a jin, while no one cares about two yuan a jin for Tang Fang.
