1, protecting ecological balance
Misgurnus anguillicaudatus is one of the important members of freshwater ecosystem. They play an important role in rivers, lakes and ponds and are an important link in the food chain. If the number of loach decreases, it will have an irreversible impact on the whole ecosystem. Prohibition of fishing loach can protect loach population and maintain the balance of freshwater ecosystem.
2. Rational utilization of fishery resources
Fishery resources are limited. If people catch loach without restriction, it will easily lead to the depletion of loach resources and eventually lead to the shrinking of fishery production. Prohibition of fishing Misgurnus anguillicaudatus is conducive to the protection and rational utilization of fishery resources and the sustainable development of fishery production.
3. Maintain social public order and good customs
Misgurnus anguillicaudatus fishing is still popular in some areas, but this activity may cause some social problems. For example, some people may catch loach by illegal means, which will not only destroy the ecological environment, but also endanger the safety of themselves and others.

As long as the soil is moist, loach can survive in water-deficient environment for a long time. Misgurnus anguillicaudatus has strong adaptability to the environment, so among the fishes of Misgurnus 100, only Misgurnus anguillicaudatus has the largest number and the widest distribution.
