Why don't southerners eat carp?

Carp, as an ingredient, can be said to be a basic entry-level ingredient. Many restaurants in the north often see carp, but they have always heard friends say that "Southerners don't eat carp". Why?

Summarize several reasons on the Internet, please give me a suggestion to see which is the real reason:

1, the reason why Bian Xiao thinks it is not very reliable:

Superstition, there is a legend that carp is a psychic and cannot be eaten. Eating it will bring disaster and retribution, which is similar to the reason why northerners don't hit weasels, because weasels are big immortals.

2. From a medical point of view, the legend is what Chinese medicine says: carp is a hair, and the climate in the south is mostly hot and humid. Some people with wounds or sores are difficult to heal after eating carp, especially those who are pregnant, post-operative and traumatized.

3. The meat quality of carp is different between the north and the south: because of the huge climate difference between the north and the south, it also has a great influence on the meat quality of carp. The carp meat in cold water in the north is tight and elastic, while the carp meat in the south is a little loose and inelastic, and the taste of the cooked food will be much worse. In addition, the earthy smell of northern carp will be lighter than that of southern carp. The most famous Yellow River carp is the representative of northern carp.

4. The eating habits of the north and the south are different: in the north, the main practices of carp are braising in soy sauce, sweet and sour, sauce burning and so on. And the taste is partial; In the south, the taste is relatively light, and the way to eat fish is mainly steaming and stewing, and it is less seasoned with star anise and bean paste, which can't cover up the fishy smell and affect the taste.

The south is rich in aquatic products, and the fish species are much richer than the north. There are many fish to eat, and the meat tastes and nutrition are much better. Carp can only be the last choice.

There is also an interesting saying that southerners don't eat carp, which is misled by northerners. Why? It is said that fishermen in the north think the carp in the south is very good and want to sell it to the north at a low price, but how to reduce the price? I thought of such a method: saying that carp is wool, and sick people can't eat it, which is easy to induce diseases. After a long time, southerners seldom eat carp. This statement is relatively rare, which is a bit inconsistent with the actual feeling.

In a word, I summarized some reasons online. Which statement do you think is the most credible? Or is there a more accurate statement? Please leave a message below to share.
