7. Update on Planning for the NPAFC International Workshop
on Explanations for the High Abundance of Pink and Chum
Salmon and Future Trends
were two high-seas tagging experiments planned for the 2011 field season.
Japanese scientists planned to use 100 tags during the
R/V Hokko maru
cruise in the central Bering Sea in July-August, and US scientists planned
to use 100 tags during the
F/V Bristol Explorer
cruise in the northeastern
Bering Sea in September. Newly reported disk-tag recoveries include
53 by Japan, 3 by Russia, and 2 by the US. After completing age
determinations for fish tagged and released in 2010, the tagging database
will be updated and copies will be distributed to the Parties and the
Secretariat.
A US working group member has proposed a discussion of the continued
usefulness of high-seas tagging experiments using disk tags and data
storage tags:
“Should continued high-seas tagging of salmon be a
research priority for NPAFC science? High-seas salmon
tagging under INPFC was important for management of
high-seas salmon fisheries and instrumental in helping
define what is known about ocean distribution of different
groups of salmon around the Pacific Rim. Can high-seas
tagging provide new information on possible changes
in distribution and migratory patterns of salmon due to
changing ocean conditions (global warming)? NPAFC
scientists are encouraged to have discussions regarding
the continued usefulness of additional high seas tagging
research both with traditional disk tags and with archival
data storage tags.”
The Working Group will continue discussion of this topic.
The Secretariat provided an update on the planning for the upcoming
Workshop. The Workshop planned to held at the Vancouver Island
Conference Centre, Nanaimo, BC, Canada.
