Resumo: | Defining the economic and social importance of shellfish culture and evaluating its expansion potential through the identification and classification of the major constraints and the research and development orientations that could lead to this expansion. Reports show that the economic importance of shellfish culture varies from one country to the other. These differences come from the variations in the amounts produced but also from the evaluation methods used. One of the controversial points deals with the production charts which often include, without distinction, fished and farmed shellfishes. Shellfish culture is fundamentally an extensive exploitation mode, similar to extensive terrestrial farms. However, interventionism varies from one country to the other to control and improve the production. The more developed system can be found in Japan where the natural ecosystem is modified, not only in favouring the seeding, but also in fighting against competitors and predators and in building shelters. The typical example is that of the king scallop for which the production of natural stocks went up from 30,000 tonnes to 100,000 tonnes thanks to the intensification of juvenile seeding and the elimination of starfishes.
