The increased marine
mortality of some salmon stocks in recent years is a pressing concern in
both the North Pacific and North Atlantic Oceans as well as in the Baltic
Sea. In response to this
situation a joint meeting, co-sponsored by IBSFC, ICES, NASCO, NPAFC and
PICES, was held in Vancouver, Canada during 14–15 March, 2002 to review
and exchange information on the causes of recent changes in marine
mortality of salmon. The
objectives of the meeting were: (1) to improve understanding of the
mechanisms resulting in the increased mortality,
(2) to identify research
and (3) to stimulate enhanced cooperation and information
exchange in the future. The
meeting, which was the first of its kind to bring together five
inter-governmental organizations to review information on salmon in the
three areas, was attended by 142 delegates.
Sessions were held on the status of salmon stocks and fisheries,
and the possible factors associated with increased marine mortality of
salmon, which were considered under three groupings - climate and
oceanography, human-induced effects, and ecological factors.
In addition there was a synthesis and general discussion session.
A total of 21 oral and 16 poster papers were presented.
In the following synthesis Peter Hutchinson (NASCO), David Welch
(PBS, Canada), George Boehlert (NOAA/NMFS, USA), and Ken Whelan (Marine
Institute, Ireland) have summarised the main points that emerged from
these presentations and the subsequent discussions, and have drawn some
