The
North Pacific region is home to multiple species of salmonid
fishes, including anadromous Pacific salmon that regularly migrate
from freshwater to the sea and back. Salmon provide economic
benefits in the form of subsistence, commercial, and recreational
fisheries, and contribute to the cultural enrichment of the
regions where they occur. Their ecological role is complex as
they facilitate energy transfer directly and indirectly at multiple
trophic levels in many ecosystems. Their ability to occupy habitats
in fresh, salt, and brackish water has led to a remarkable diversity
of life histories, but climate change threatens to alter their
distribution and abundance.
Salmon are found
most frequently in cooler regions of the Pacific Ocean. In recent
years, commercial catches have been among the highest on record,
with no indication of declines. For instance, 2007 catches exceeded
1 million tonnes, with pink and chum salmon constituting 51
and 31% of the catch by weight respectively. Yet coho, Chinook,
and some sockeye salmon populations are declining in many areas.
This one-day workshop
will examine scenarios for the future of Pacific salmon, based
on climate projections from coupled ocean/climate or other models
or from statistical projections of expected climate changes.
The workshop will emphasize regional scales that are believed
to be of particular importance. For example, global warming
may enhance oceanic conditions for some species in some regions,
while diminishing them for others. A good understanding of potential
interactions between regional physical and biological processes
is critical for accurate projections of such regional responses.
The workshop will provide an opportunity to examine whether
the responses of salmon populations to climate change will differ
among regions, and what the mechanisms might be.
It is expected
that papers presented at the workshop, as well as documentation
from the panel discussion, will be submitted for publication
in the Symposium volume.
