1, destroying the ecological balance.
One of the fundamental reasons for prohibiting fishing with loach is to protect the ecological balance. Misgurnus anguillicaudatus is the food of many carnivorous fish. If you fish with loach and happen to meet a group of fish, the carnivorous fish in the water will be fished out in a few days. Once carnivorous fish are greatly reduced or disappeared, other fish will multiply and the ecosystem will be destroyed.
2. Misgurnus anguillicaudatus has strong reproductive ability.
Misgurnus anguillicaudatus has strong vitality and reproductive ability. Fishing with loach requires nesting with loach. Some "local tyrants" fishing friends may put dozens to hundreds of kilograms of loach to build nests. Once the carnivorous fish population is not enough to eat up the loach, then the loach will multiply in large numbers.
