How to judge the wild crucian carp? What are the ways to judge whether it is wild?

1, the living conditions of wild crucian carp are definitely worse than those of cultured crucian carp, so cultured crucian carp are generally small and flat, and the back of wild crucian carp is black and blue with light scales.

2. If the wild river is Qingshui River, there are many aquatic plants and silt in it, then the crucian carp caught is generally golden yellow or dark black. If the river you catch is mixed, then what you catch is more white, which is different from the fresh white in the fish pond.

3. The difference between wild crucian carp and cultured crucian carp is that one eats with his mouth open and the other forages everywhere. In this way, the scales under the mouth of wild crucian carp will become hard when dealing with the soil for a long time, while cultured crucian carp will eat floating objects with their heads wide open every day, so experienced people will know which one is wild and which one is cultured when they look at the mouth of the fish.
