Analyse bio-économique des activités conchylicoles en France : perspectives et limites

Bio-economic models have not been extensively developed for the shellfish farming sector. However, this type of model could constitute a valuable analysis and assessment tool. Only the potential contribution of this kind of model in our knowledge of the evolution of production systems and marketing are discussed here. These models help comprehend the interactions between the strategies of the different players in the sector and also-on the level of individual businesses-between the shellfish farming sector, as well as the other economic activities that utilise shellfish farming areas, and the type of activity. In particular, it is possible to show the externalities that affect shellfish farming (for example, by revealing the relationships between nutrient loading and production in quantity and in value) and to assess the economic repercussions of alternative scenarios in space allocation or utilisation.
