Introduction aux problèmes socio-économiques de la mariculture extensive: expériences japonaises

The term “extensive mariculture’’ covers two main types of production: the exclusive territorial-right-based aquaculture of fixed species and stock-enhancement-based fisheries. The releasing of juveniles, with or without the supply of adequate habitat, is at present the main form of stock enhancement. Japanese experience shows the difficulty of clearly assessing the benefits of marine ranching, and then ensuring its management. Some of the main aspects of this management are presented here: public and private cost-benefit analysis, the relation fishing/aquaculture/sea ranching, and the role of collective organization for management.
