Ahi Tagging Demo
Taken at the Oahu Ahi Tagging Workshop. Clay Tam demonstrates the proper technique of inserting a conventional tag into an 8lb big eye tuna.
Insert the tag at the base of the second dorsal fin. The tagging stick should be aimed at a 45° angle, aiming to get the dart beneath the dorsal fin rays (small bones that hold up the dorsal fin).
Pull on the tag to ensure that the tag's barb is caught on the opposite side's fin ray bones. If the tag is loose, pull it out and start again if the fish looks like it is doing ok.
The tag's barb should be anchored by the fin ray bones as shown. (Please don't dissect the live fish to check!)
