World aquaculture has grown dramatically in the last 50 years, mainly in Asia, and is expected to increase further. In the meantime, aquaculture production of Japan has stabilized and occupies an important position in the entire fishery, but the effects of that situation in Japan are in severe. The situation is due to increased costs of fuel oil, fish meal for feed, the high cost of quality fish for stocking and sluggish fish prices caused by the economic recession, along with losses caused by red tide and outbreaks of disease. Due to those factors, the aquaculture industry in Japan is faced with high production costs and low prices for its products.
 To improve the management of aquaculture, it is necessary to shift to a sustainable and profitable structure through a review of the entire production process. We organized an overview of aquaculture production systems, and have discussed research problems and directions for solving them. To achieve sustainable aquaculture, the industry must reduce the environmental impacts, as well as need to be profitable. For low impact on the environment, research and technological innovation are needed on larvae and fry production that is independent on natural resources, improvement of culture methods and feed quality and so forth. To increase revenue, it is necessary to practice continual cost savings by analyzing each process of associated with aquaculture production and development of a way to add value to products. Thus, it is important that aquaculture becomes regarded as an integrated production system.
