World aquaculture has grown dramatically in the last 50 years mainly in Asia, and is expected
to increase further. On the other hand, aquaculture production of Japan has changed almost stably,
and occupies an important position in the entire fishery, but the affaires of that are in very severe.
It is due to such as increased production costs of fuel oil and fish meal for raw material of feed,
restraint purchasing of high grade fish and sluggish of fish price by economic recession, and
damage of red tide and outbreak of disease. From such a situation, aquaculture industry of Japan
has fallen into the production structure of high cost and low price.
To improve the management of aquaculture, it is necessary to shift to a sustainable and
profitable structure by a review of the entire production process. We organized an overview of
aquaculture (aquaculture production system) as shown below, and have discussed research
problems and directions of solutions in each category. For sustainable aquaculture, industry must
reduce the environmental impact, as well as needs to be profitable. For the low impact on
environment, research and technological innovation are needed on artificial seed production that
is independent on natural resources, improvement of culture methods and feed quality unaffected
to water quality and so on. To increase revenue, it is necessary to practice continual cost savings
by analysis each process of aquaculture production and to develop a way to add high value to
products. Thus, it is important that aquaculture is regarded as an integrated production system for
considering the future research.
