First Recapture of Tagged Blue

Japan Game Fish Association (JGFA) has long advocated tagging & releasing billfish, and its effort incudes cooperation with National Research Institute of Far Seas Fisheries (FSF) to use satellite-tracking pop-up tags.

A blue marlin recently caught by a long-line fisherman off Chiba area had a regular TBF tag (BF-121940) , and it proved to have been previously caught more than a year ago in Mie area, approximately 600km west. The recapture will give us a clue on the mysterious migration pattern of marlin in Japanese water. It was a fish caught by Mr. Yasushi Yamada, in a monthly tournament of JGFA's Boat Owner's League.
Congratulations, Mr. Yamada!
