Figure 9. — Herring Tagging operations. 
The tagging live box is filled with herring which the man with the net dips a few at a time into the half barrel of sea water under 
the shelter. From this half barrel the herring are removed one at a time by hand and placed on damp cheesecloth stretched 
over a frame. A sharp arrow-pointed knife is used to puncture a small hole through the wall of the belly and the flat metal 
tag is inserted within the body cavity of the herring, the small wound healing completely within a few days.
