Several problems concerning the relationship between the demand and supply of fishery products in Japan are outlined in this study. Interactions between ecological functions of the coastal areas known as fishing grounds, and four fishery production processes (the cultivation fishery, the resource management type fishery, the coastal fishing ground development practice, mariculture) are summarized. In addition, this study describes the framework of the technical combination surrounding fishery researches. From views of fisheries that are responsible for the stable supply of safe fishery products, the ecologically compatibility production method is structured into three types (the symbiosis type, the compatible type, the conservation type). Ecological explanations are also provided to describe each type of the method. Further, management objectives and standards are proposed for the sustainable fishery production by effectively utilizing structural characteristics of an ecosystem, and notable issues raised at production settings are outlined. Lastly, a functional evaluation model necessary as a guideline for the protection of fishing environments and for the sustainable production is classified and roles of the model are summarized.
