Grass carp has many spines, one of which runs through the whole body. It is the most important fishbone and plays a major supporting role. In addition to this big thorn, there are some small thorns, and sometimes these small thorns are relatively small, which will be more troublesome to handle.
Specifically, the number of these small thorns is still relatively large, which can reach several hundred. But specifically, different grass carp individuals contain different fishbones. Some grass carp have many small bones, while others have few. But compared with other species, grass carp has more thorns.
