Look at the scales: the scales of wild carp are close to golden yellow, and the scales of non-wild carp are dim. Look at the fins: the fins of wild carp are bright red, while those of non-wild carp are very black. Look at the internal organs: the internal organs of wild carp are relatively clean and have no grease. Look at the head: the head of wild carp is small and triangular, while the head of cultured carp is larger. Look at the color of the mouthparts: the mouthparts of wild carp are white or light green, and the mouthparts of non-wild carp are gray. First, how to see whether carp is wild 1. Look at the fish scales: the fish scales of wild carp and farmed carp are very different in color. You can judge whether carp is wild by observing fish scales. If it is a wild carp, the scales are close to golden yellow and very shiny. However, if carp are farmed, their scales will be darker.

2. Look at the fins: You can also observe the fins of carp. If they are wild carp, their fins are generally bright red, while those of non-wild carp are generally darker.

3, look at the internal organs: if you cut open before eating, you can observe their internal organs. If it is wild carp, then the internal organs are relatively clean, and generally there is not much oil. This is not the case with cultured carp, because they eat more feed and grow faster, so there is more oil accumulated in their internal organs.

4. Look at the head: In addition, it can be compared by the size of the head. The head of wild carp is generally small, and the proportion in their bodies is relatively small; Generally triangular in shape; However, the head of non-wild carp is generally fat and nearly round in shape.

5, look at the color of the mouth: You can also let the carp open its mouth and then observe the color of its mouth. The food of wild crucian carp is generally aquatic animals or plants, and its mouth color is generally white or light green. The food that cultured carp eat is mostly feed, and their oral color may be close to gray or even black.

Second, can wild carp be domesticated? If wild carp are caught in the wild, some anglers may want to keep them at home. However, it is still difficult to feed wild carp if they are domesticated, because they have adapted to the wild environment and may not adapt to the tap water environment at home. However, if they can adapt successfully, they can also be domesticated.
