Our mission
|
Japan Sea
National Fisheries Research Institute (JSNFRI) is in charge of research
concerning fisheries and aquaculture in the
Japan Sea, from
Aomori to Yamaguchi prefectures. Our aims are the sustainable use of fish and
shellfish resources and the successful development of fish farming and
aquaculture, in cooperation with prefectural research institutes of fisheries in
this area.

Brief history
|
Jun. 1949:
JSNFRI was established in Nanao, Ishikawa Prefecture, as an
institute of Fisheries Agency, Ministry of Agriculture and
Forestry.
Dec. 1952:
JSNFRI was moved to Bandaijima, Niigata-shi.
Apr. 1965:
JSNFRI was moved to the present address.
Apr. 2001:
Fisheries Research Agency (FRA) was established by combining the research
institutes of Fisheries Agency including JSNFRI, in accordance with the
administrative reform policy of the Government.
Oct. 2003:
Japan Marine Fisheries Resources Research Center and Japan Sea-Farming Association
were united with FRA.
Apr. 2006:
National Salmon Resources Center was united with FRA. JSNFRI initiated research on salmon
resources.

Project Management Division
|
Project Management
Division has three sections, Planning and Coordination, Salmon Resources
Research, and Management sections, to totally manage the research activities in
our institute.
The Planning and
Coordination Section plans and arranges research projects as a research base in
the Japan
Sea area
coordinating other research institutes in this area. This section is also engaged in collecting
information concerning research subjects, promoting public relations through our
web site and publications, and managing our library.
The Salmon Resources
Research Section performs research on resources and ecology of the salmon,
environment of its habitats, etc., and diffuses the results
obtained.
The Management
Section is engaged in general affairs such as personnelfs salary and welfare
program, accounting, and facility maintenance, etc., to support research
activities.

Research
Objective
In order to
ensure the sustainable use of fisheries resources in the
Japan Sea, our division conducts stock
assessment of the commercially important species. We also conduct research to understand the
mechanisms of fluctuations in stock abundance and to clarify biological and
ecological characteristics of the commercially important species to contribute
to the management of fisheries resources.
Stock
Assessment Section
Stock
assessment is conducted on the commercially important species such as snow crab
and Japanese common squid. Factors
affecting the fluctuations of these stocks are also
investigated.

stock assessment
e
Biology
Section
Biological
and ecological studies are conducted on pelagic and benthic organisms such as
Beni-zuwai crab, flathead flounder, and on the eggs and larvae of some fish and
squids.

Sea Fisheries Oceanography Division

Research
Objective
The Japan
Sea is a semi-enclosed marginal sea area that consists of the Tsushima Warm
Water, Subarctic Cold Water and Japan Sea Proper Water (bottom water deeper than
300-500m).@ Our research objective is to elucidate physical and ecological
structures, which affect fisheries resources, through long-term research on the
physical and biological environments in this distinctive sea area. In addition, we conduct research on jellyfish
blooms, an emerging problem that causes serious damage to the fisheries in the
Japan Sea.
Physical
Oceanography Section
Physical
structures of the Japan Sea and various processes of their
change are studied by monitoring the currents, water temperature, salinity,
etc.

mooring system for long-term monitoring of

Biological Productivity
Section
Ecology of
prey organisms, indispensable as food for fisheries resources, is studied by
examining the species composition, their biomass, correlations with reproduction
of predatory fish, etc.

Coastal Fisheries and Aquaculture Division
|
Research
Objective
The research
scope of our division is focused on the promotion of fisheries including fish
farming and aquaculture in the coastal waters of the
Japan Sea.
Our studies are aimed at clarifying the physiological and ecological
characteristics of the species useful for resource enhancement and aquaculture
and understanding the ecosystem in the coastal waters.
Resources
Enhancement Section
Productivity
of food organisms to support commercial species is investigated in the fishery
ground for more effective resource enhancement.

Coastal
Fisheries Resources Section
Studies on
ecology and genetics of target species for resource enhancement are
conducted. Stock assessment is also
conducted on Japanese flounder and red sea bream.

Coastal
Fisheries Promotion Section
Population
structures and dynamics of useful animals such as gastropods and sea urchins are
investigated in rocky fishery grounds.
Experimental studies are also conducted to elucidate the behavioral
characteristics of these animals.
