Yesterday afternoon, the relevant person in charge of Chaohu Administration confirmed that the "strange fish" in the fishermen's mouth was a red-toothed tiger fish. It may be that the fish invaded the waters of Chaohu Lake with the river when the project of "diverting the river into the nest" was implemented in recent years.

Is the red wolf-toothed tiger fish a harmful fish species? Yesterday, Zhang Zuguo, a professor in the Department of Fisheries of Anhui Agricultural University, said that gobies are non-toxic and inedible and cannot be simply defined as harmful fish species. "But it is ugly in appearance and small in length, and it is of little use at present." Professor Zu said that water ecology is actually a balance of fish population. If this balance is broken, it will cause disaster to other small fish and shrimp, and "the red wolf tooth tiger fish will bring harm."

What impact will the invasion of the red wolf-toothed tiger fish have on the fish ecology in Chaohu Lake? Professor Zu said that the red-toothed tiger fish likes eat small fish shrimp, which will definitely affect the fish and shrimp in the water. "The decrease in white shrimp reflected by fishermen illustrates the problem." But how big the harm is, it needs specific investigation and study.
