3. National Research Plans Under the New NPAFC
Science Plan for 2011-2015
The individual national research plans of Canada, Korea, and Russia under
the new NPAFC Science Plan
) were presented at the 2010 CSRS
meeting. Canada’s research plan is described i
Korea’s research
plan is described in
, and Russia’s research plan is described in
. At the 2011 RPCM the national research plans of Japan
) and
the US under the new NPAFC Science Plan were presented.
(a) Japanese Salmon Science Plan 2011-2015
The national salmon research plan of Japan under the NPAFC Science
Plan is described in
. The 2011-2015 NPAFC Science Plan
defined as its research theme “Forecast of Pacific Salmon Production
in the Ocean Ecosystems under Changing Climate” with five research
components
). It is a high priority for Japanese salmon
research to explain and forecast the annual variation of salmon
production, which relates closely to the new Science Plan theme. The
primary goal of Japan’s research plan is to achieve sustainable salmon
fisheries with conservation of wild and hatchery stocks in the North
Pacific ecosystems. Japan’s research plan consists of four components:
(1) juvenile salmon studies, (2) high-seas salmon studies, (3) monitoring
of major salmon populations, and (4) development and application of
stock identification techniques and forecast model.
J-1: Juvenile Salmon Studies in Coastal Waters
.
Early life history studies are important to understand survival
mechanisms of salmon. To clarify mechanisms controlling population
dynamics of juvenile salmon, Japan will focus on the following research
items.
Feeding, growth, and survival of juvenile salmon
Stock-specific distribution and migration of juvenile salmon
Monitoring of coastal environments such as SST, salinity, primary
production, and prey organisms
J-2: High-seas Salmon Studies in the Bering Sea and Adjacent Waters
.
The Bering Sea is an important feeding habitat for various salmon
populations including Japanese chum salmon. The BASIS Phase II plan
is designed to understand how climate change will affect Pacific salmon
production and ecosystems in the Bering Sea
