? There are many kinds of fish, their appearance is different, and their body structure is also very different. The difference is also reflected in the structure of fish scales, some fish have scales, some fish do not have scales, some fish have scales, but the scales are very small, so it is not obvious. Fish can also be divided into scaly fish and scaleless fish according to the existence of scales and the size of scales. The herring is a scaly fish. The scales of herring play a very important role for them. First of all, fish scales can keep harmful substances and bacteria out of the body of herring, so that they are not easy to get sick. In addition, the fish scales are relatively smooth, and sticking to the surface of the herring's body can also properly reduce the resistance they receive in the water, so that their activities in the water will not be too laborious.
Herring is a kind of fish that can be used as food, although their scales play an important role for themselves, but for humans, it is necessary to remove the scales as food, and it will be a little troublesome to scrape the scales.
? As mentioned above, herring is a kind of fish that can be used as food, but not all body parts of herring can be eaten. Their gallbladder is poisonous and harmful to human beings. If humans eat herring bile, they may be poisoned. The more common toxic reactions are vomiting and diarrhea. If they eat too much, they may lead to more serious reactions, such as coma, convulsions and so on. Therefore, when using herring as food, it is better to remove their gallbladder first. Herring meat is non-toxic and edible, but try not to eat too much, otherwise the burden on the digestive system will be heavier.
