Hairtail has three rows of fishbones. The hairtail that comes back should be treated quickly while it is fresh. The hairtail has only three rows of fishbones: the dorsal fin is connected with a row of backstab, the middle spine and a row of nail-like abdominal spines. Starting from the tail of the fish, pull up the dorsal fin, and then pull it obliquely toward the head to pull out all the dorsal fins, so that eating hairtail is much easier. Remove internal organs, fish heads and peritoneum. These parts are particularly fishy and must be removed.
