Recently, a young fisherman in Yongzhou, Hunan caught a strange-looking "strange fish" while fishing in the local wild river. As a fishing enthusiast, common local fish are very familiar, such as crucian carp , carp , silver carp, sun fish , small fish, such as tart , nail fish, lying tiger, etc.

However, this strange fish made fishing enthusiasts a little confused. It was a completely strange fish I had never seen before. I thought it was a protective species and released it. It is reported that the strange fish is green all over, with fine and shiny scales, and looks very beautiful, and its body looks a bit like grass carp . This angler believes that it should be a rare and unique fish species.

What species is the rare "strange fish"?

Regarding the rare strange fish of Hunan guys, many netizens said: The fish is called Qinglong and Qingyi Fish (called Qingbo Fish in Sichuan). Since the species population is very small, its market price is about several hundred yuan per catty. So, what kind of fish is Qingbo fish?

Qingbo fish is scientifically called Chinese barbs horn , native to Yangtze River and its tributaries, mainly distributed in the upper reaches of the Yangtze River, especially in Yunnan, Sichuan and Hunan, the rivers are widely distributed and have a large yield. They were once a very common fish species in the Yangtze River.

Qingbo fish body is relatively flat, with a small and pointed head, long neck whiskers, short whiskers, hard thorns, strong dorsal fin, and serrated thorns at the back edge of the last hard thorn. The chest, abdomen and anal fins are hard, and there is a black spot at the base of the caudal fin.

The water temperature suitable for growth of Qingbo fish is between 22 and 28 degrees Celsius, and the dissolved oxygen is between 4 mg/L. Therefore, the living environment of this fish is mainly in the upper reaches of the Yangtze River, mainly in rivers with relatively rapid flowing water and rocky bottoms. In mid-November, it enters the river bay to overwinter and becomes a small group of people living in caves, stone caves, rocks and other places.

Due to the mixed food nature of Qingbo fish, it eats the surrounding bait and vegetable leaves, grains, cerves, copepods, etc. that go deep into the bottom of the water. It grows fast and has a large individual (maximum 25 kilograms). The meat is tender and delicious, rich in nutrition, and has strong disease resistance. Its economic value is very high.

Why is Qingbo fish so rare?

Once, Qingbo fish was a common fish in the upper reaches of the Yangtze River, why has many people not seen traces of Qingbo fish activity in recent years? There are two main reasons:

First, overfishing, because the economic value of Qingbo fish is very high, as a common fish in my country, it is caught in large quantities, resulting in a large-scale reduction in the fish population, affecting population reproduction and destroying the ecological balance.

Second, water pollution is serious. With the development of industry, a large number of factories are established around the river. Due to poor management of some enterprises, a large amount of wastewater and waste residue are discharged into the river, resulting in river water pollution and a large number of biological populations disappear.

Currently, most of them are artificially bred and are currently successful in Sichuan and Chongqing. Therefore, the number of Qingbo fish populations in the Yangtze River Basin has dropped sharply, even rare species.

However, the breeding requirements for Qingbo fish are very high, such as the quiet environment, rich water resources, good water quality, convenient drainage and irrigation, etc. There are also special requirements for the breeding farm, such as sand and stone as the bottom quality.

Therefore, the discovery of Qingbo fish in Hunan this time fully demonstrates that the local ecological environment is very good and is suitable for the survival and reproduction of Qingbo fish.

summary

As a fish population with very high economic value in my country, the emergence of wild species is actually an affirmation of the local ecological environment.

Therefore, we should protect the local ecological environment and clearing fish, and give thumbs up the behavior of the young man in Hunan to release animals. We look forward to the emergence of more fish species in our rivers in the future.
