A local witness confirmed that the fish jumped out of the water, mainly silver carp, in the waters between Daguanyi and the gate bridge of Xi 'er River. This phenomenon lasted for about two hours, and it was not until after 20 o'clock that the water basically returned to calm.
According to local fishermen, it is not surprising that there will be this landscape at this time of year. And according to my years of fishing experience, I expressed my thoughts. It is estimated that the wind blew the phytoplankton to the Xi 'er River, and a large group of silver carp followed the phytoplankton to the Xi 'er River for food. After the fish were frightened, they jumped out of the water, followed by a chain reaction, causing more silver carp to jump out of the water.
Silver carp is wild, likes to jump, and will live in groups with phytoplankton. When we raise fish, we usually try not to go to the downwind. If we accidentally scare the silver carp, they will jump out of the water in groups. Jump up and collide with each other, and you will be injured and killed.
According to the testing by professional technicians, there is no problem with all the data of water quality in the fish jumping area. Most of the jumping fish in the field are silver carp. They have social habits. Sampling and anatomy show that this fish is huge and has reached sexual maturity. Affected by the ecological outflow of Erhai Lake, fish schools gather near the waters near Erhai Lake. In addition, influenced by the recent weather, high temperature, low air pressure and dissolved oxygen, a large number of fish that have reached the breeding conditions fly out of the water. Putting silver carp is an effective way to implement biological limitation in Erhai Lake area.
From this, we know that the truth of police officer Yu Teng's appearance of Xi 'er River in Dali is actually inseparable from environmental factors. Silver carp reached the season of sexual maturity. Due to the influence of the weather and the high temperature, the fish that reached the breeding conditions jumped out of the water, causing such a spectacle.
