The bass is one of the common fish, many parts of the fish have scales, and the scales are more. Perch also have fish scales, fish scales play an important role. The scales of sea bass are smooth, so that they can reduce friction resistance in the process of swimming, and their swimming speed will be faster. In addition, the scales of bass also play a role in protecting their body, which can be said to be the "external skeleton", which plays a role in isolating the body from harmful bacteria. Also, the scales themselves can reflect light, which can play a role in camouflage, deceive some carnivorous fish, so that bass can better survive.
However, when eating sea bass, these scales need to be removed, otherwise it will affect the overall taste. You can choose to beat them raw, which means you can remove the scales immediately after killing them. You can also choose the way of cooked beating, that is, first put them into boiling water to scald, and then remove the scales on the surface, so that it is easier to clean the scales.
Swim bladder is one of the important organs of fish. Most bony fish have swim bladders, and many cartilaginous fish do not. Perches are a group of bony fish that have swim bladders. The role of the swim bladder is very important. The swim bladder helps the bass breathe as it does so. In addition, the swim bladder allows the bass to move, allowing them to rise or fall slowly without using their own strength. However, the swim bladder of bass is not completely free. After the perch dies, the air in their swim bladders is expelled, as if they had no swim bladders.
