H. Imai of Japan presented scientific information relevant to help enforcement activities regarding 2009 salmon migration patterns and the areas possible for illegal activities.

The presentation centered on scientific information collected by the Japanese research vessel Wakatake Maru using archival tag technologies that modelled salmon homing migration patterns from the Bering Sea to the coast of Hokkaido, Japan.  This study indicated that salmon migration patterns were influenced by the swimming depth and the changing temperatures observed in the vertical water column.

H. Imai reported that this experiment was not easy due to the high cost and the difficulties of recovering the archival tags.  Japan is determined to continue their research on salmon homing migration behaviour.
