Fish scales play an important role in fish, and the scales of mackerel play a similar role in them.The scales of Spanish mackerel stick to the surface of their bodies and play a role in protecting their health.This is because, with the barrier effect of fish scales, some harmful bacteria and microorganisms in the sea water will not enter the body of mackerel.In addition, the scales of the mackerel can also reduce some of the resistance they encounter in the water, so that they can swim more easily in the water.However, when we use it as an ingredient, we need to remove this part of the scales.
As mentioned above, the mackerel has scales, but their scales are relatively small and thin, and sometimes it is not easy to observe.Scaleless fish are classified according to the presence or absence of scales, but they can not be understood literally, because scaleless fish include not only species without scales, but also species with smaller scales.In this respect, mackerel belongs to a kind of scaleless fish, which belongs to a group of small scales.
