Hunan Daily, New Hunan Client, August 8 (Xu Yaping, Zhang Tudong) "Does anyone know what kind of fish this is?" At 11:30 today, Li Sihong, a co-inspector of Dongting Lake, posted a video of a "strange fish" and a picture in the WeChat group. Inspector Wang Jianhui immediately replied and instructed: "Piranhas, alien species, do not release them!"
It can be clearly seen through the picture that the fish is the size of the palm of the hand, the head is small, the jaw is not prominent, there is a large black edge on the posterior edge of the tail fin, and the teeth resemble the appearance of human molars.

Li Sihong told reporters that this fish was caught by Li Ming, a fisherman in Baling Community in Yueyang County, in the waters of the Eight Immortals Bridge in Dongting Lake, and such a fish was also the first time he saw it in Dongting Lake. The reporter immediately contacted Xie Yongjun, senior veterinarian of the Yueyang Porpoise Protection Association, and Ju Tao, an aquatic animal protection volunteer, who confirmed that the fish's scientific name is "short-covered fat carp", which belongs to an exotic species and may have escaped to Dongting Lake.
Short-lipped fat carp, also known as freshwater white pomfret, pseudo-piranha, belongs to the order Lipidoptera, Lipid carp family, belongs to a freshwater fish, distributed in the Amazon Basin of South America, the yield is very large, for the local common edible fish, and has been introduced into aquaculture in many countries, and can be used as an ornamental fish.
The reporter contacted Huang Haochen, a young fish scholar at Huazhong Agricultural University, who told reporters that fish invasion is now a global problem. He reminded fish farmers to be careful not to let exotic fish flow into local waters. Alien species reproduce quickly and lack natural predators, and once they enter the local natural waters, they may encroach on the living space of native fish in large quantities, thereby threatening the survival of native fish, damaging biodiversity, and causing significant losses to local fishery resources and production.
