1. Misgurnus anguillicaudatus has strong adaptability to water environment. Fishing with Misgurnus anguillicaudatus, especially nesting with live Misgurnus anguillicaudatus, will lead to the crazy growth of Misgurnus anguillicaudatus without natural enemies in this water area. In the long run, it will inevitably destroy the ecological balance of water body and affect the survival of other fish.
2. Reason 2: Misgurnus anguillicaudatus is the prey of predatory fish, and the use of Misgurnus anguillicaudatus for fishing will lead to the sharp decrease of predatory fish. Without predatory fish to check and balance other fish, it will multiply in large numbers, which will eventually lead to the destruction of the whole water ecological environment.
3. Reason 3: Misgurnus anguillicaudatus breeds very fast and is gluttonous by nature, and it is often in an advantageous position when competing with other fish for food and other resources. In addition, too many Misgurnus anguillicaudatus in the waters will also lead to very turbid water quality, which is very unfavorable to other fish.
