Summary of Tagqinq Results
In past years, agencies of the
United States and Canada have been handling tagging results within
their own fishing boundaries.
At the suggeston of Canadian biologsts,
the committee members agreed that an interchange of data would be
advantageous to all agencies.
This has been stated as a recommendation
and appears under that section of this report.
