1, catching a large number of predatory fish.
Predatory fish live by preying on small fish, shrimps and other fish, and this way of burrowing with loach can attract a large number of predatory fish into the nest in a short time, thus being caught in large quantities, and it is not empty talk to empty a reservoir in a few days.
2. It pollutes the environment.
Misgurnus anguillicaudatus fishing has a certain pollution to the aquatic environment, mainly because there is something wrong with the nesting loaches. As mentioned above, the nesting loaches should be soaked in medicinal liquid or other substances. These loaches roll and swim in the waters, which is nothing more than "coming back to light" to attract the pout into the nest and cannot survive.
The dead loach slowly decays in the water, which pollutes the water quality, and the liquid medicine used in the process of soaking the loach nest also pollutes the water quality. In particular, the use of loach for fishing in some areas where fishing is prohibited is more polluting to the water quality, and it is also a problem whether other fish that swallow loach can survive.
3. Destroy the ecological environment.
Aquatic ecological chain is composed of microorganisms, protozoa, aquatic animals, algae, aquatic plants, etc. in natural ecological water, forming an orderly ecological cycle, and all kinds of organisms restrict each other's growth through benign competition, thus realizing the natural purification process, and naturally growing and purifying without human interference.
Predatory fish, such as pouting, are also a part of the ecology. In the aquatic ecological environment, they can restrict the growth of fish to a certain extent, so that fish often avoid natural enemies and grow healthily. Moreover, the main food of the pouting mouth is small fish, white striped fish, pomfret fish, etc. With the decrease of these small fish, other fish can get more food, which is a virtuous circle. A large number of pouts were caught, which destroyed the ecological circle of fish.
4, against the spirit of recreational fishing.
The pleasure of fishing lies in feeling nature, feeling the beautiful scenery around you, meeting like-minded friends and relaxing in the process of fishing. What you enjoy is the pleasure of getting on the fish at the moment of lifting the pole after eating the hook, and the sense of accomplishment of catching a big fish, not fishing for harvest. Loach fishing violates the spirit of recreational fishing.
