||Despite its youth, aquaculture is an activity which is definitely subjected to the rules of international trade. The dependence on natural conditions is the first cause for the existence of national or regional comparative advantages. But both economic and institutional environment have to be taken into account when listing the assets or constraints of a location for implementing aquaculture. Because of little possibilities of economies of scale and because of fast technological spread in aquaculture, it is very difficult to obtain a price competitiveness based on industrial size of the activity or on technological advance. That is the reason why aquaculture has to look for other sources of competitiveness like the quality or the control of the market chain. As for the quality which includes not only freshness and good taste but also adequation to the increasing diversity of the demand, a lot is still to be done to get free from the natural constraints, especially upstream in genetics and nutrition. The example of the salmonid industry shows the importance of the control of the marketing in order to diversify the products. It has been a major issue in its recent development and a big help to get over several production crisis, but other sectors are far behind from this viewpoint.
