To deal with hairtail, the head, fins, tail and internal organs of hairtail should be cleaned first. After the hairtail is coiled, the fins on the back of hairtail should be pulled out directly, and then all the fins of hairtail should be cut off with scissors. The purpose of this is to remove fish scales.

2. Scrape fish scales

The scales of hairtail stick firmly to the fish body. If you want to clean the scales completely, you can rub them gently against the fish head with a steel ball, and then you can scrape them off gradually. However, it is necessary to pay attention to ensure that the hand strength is even and light when rubbing, so as not to scratch the fish.

3. Black film removal

There will be a thin but tough black film between the viscera and the meat of hairtail. To remove this black film, you can cut a small mouth along the belly of the fish with a knife, take out the viscera of hairtail, then tear off the black film directly, and then rinse it with clear water.
