The surimi line is a sensory organ in which fish sense the flow of water. On the back of the fish, there is a scale called a sideline scale. On the sideline scale, there are many well-arranged small holes, which are directly connected with the fish line in the fish body. Some smells of the external environment, such as the smell of water in the water, pass through. The small holes are directly attached to the surimi line.
Cut a knife at the next two centimeters of the fish head. You don't have to cut it deeply. Half of the fish is thick.
Find the white spots inside, hold them by hand, and slowly hold them.
Then tap the fish belly with the other hand and pull out the hand of the squid line.
The fishing line will not break.
