Jiang talked about it.

These three kinds of fish are Yangtze river swordfish, Yangtze river puffer fish and Yangtze river shad, and they are also called "Yangtze River Sanxian". However, in recent years, driven by huge economic benefits, some greedy people have caught a large number of these three kinds of fish, among which shad can be said to be basically extinct, and the output of swordfish has also dropped seriously, and the price has been rising all the way. Because of its toxicity, puffer fish is similar.

1, Yangtze saury

Yangtze river swordfish, officially known as bonito, belongs to migratory fish, and its meat quality can be said to be very delicious. It is also for this reason that it is widely loved by many diners. Because of its strong market, short supply and higher price, people call it the most expensive fish in China. In recent years, under the temptation of huge interests, some greedy people have overfished it.

Therefore, the agricultural management department has increased the protection of the Yangtze River saury. With the protection of wild swordfish, it also ushered in the spring of artificial swordfish breeding. With the worldwide problem of artificial swordfish being overcome, it is believed that artificial swordfish will appear in the market in the near future, which will be more conducive to the protection of wild swordfish.

2, the Yangtze river shad:

In ancient times, shad was a tribute and was usually eaten only by dignitaries. In China, it is a rare and precious economic fish. The reason why it has been loved by people since ancient times is mainly because of its high nutritional value and delicious meat. Fat is rich in calcium, phosphorus and iron. Besides its nutritional value, it also has certain nourishing, aphrodisiac and heat-clearing effects, so it is called "the king of fish"

3. Yangtze puffer fish:

The puffer fish lives widely in the Yangtze River, and its fishing peak is usually in the flood season. Generally speaking, people choose spring and summer as the best catching periods. At the same time, puffer fish are poisonous, and its toxins are mainly used to protect themselves. When they are in danger, it will spit out toxins to attack the enemy.

It is precisely because of its toxin that some people who like to eat it once loved and feared it. Only in modern times, with the maturity of cooking technology, the processing methods of puffer fish have been greatly improved, and more and more puffer fish have entered people's tables and are widely loved by diners.
