The dangers of loach fishing are as follows:

The loach fishing method will not only cause disaster to the fish, but other fish in the water will also be implicated. We all know that whether in water or on land, the survival of animals is closely related to other animals. The so-called law of nature, when an animal faces extinction, the animals involved or relying on it for food will also be fatally affected. threaten.

For example, the crocodile fish in the water, their main food is some fish and shrimps. If there is no crocodile fish to check and balance, then the entire ecological chain will be destroyed. These fish and shrimp will have no natural enemies, and then they will Massive reproduction has caused uncontrollable consequences, so loach fishing not only harms fish such as cockroaches, but also affects the ecological balance of the fishery, which is quite destructive.

Loach is a benthic fish that inhabits the bottom of rivers, lakes, ditches, paddy fields, ponds and other shallow water and silt environment waters. It is diurnal and nocturnal. It has strong adaptability and can live in an environment rich in humus.

When there is lack of oxygen in the water, it can jump to the surface of the water and swallow air for intestinal respiration. When the pool dries up, it dives into the mud. As long as the soil remains moist with a small amount of water, it will not die. Loach is widely distributed in China, Japan, North Korea, Russia and India along the Asian coast.
