| The different methods of estimating the trophic capacity of ecosystems cultivated by oyster farming and mussel farming are introduced by ascending order of complexity. Thus, production yields make it possible to monitor whether the size of the farmed stock is being successfully matched with the availability of food. Moreover, the study of annual production farmed stocks has made it possible to create comprehensive dynamic models that show the maximum annual production that a given ecosystem can support. These last two approaches assume the environment to be constant. The study of trophic links that can simulate growth performance of molluscs can be classified according to two criteria, (i) their level of complexity in combining biology and physics, (ii)... |

| The objectives for 2004: - Continuation of the study of the "on-bottom/off-bottom" mortality south of the Marennes Oléron Bay with a study of acute stress (sequel to Dynamo & DynamoR studies) (WP 2.2.8). - Continuation of the laboratory analysis of the dynamoR 2003 samples (biological material) and data (WP 2.2.3). - Analysis of the data on the characterisation of summer mortality (WP 2.2.1) in relation to the environment. Through these tasks, the objectives are: (1) understanding the "on-bottom/off-bottom" mortality model of C. gigas in the Marennes Oléron Bay and underlining the environmental causes of summer mortality, (2) bringing a regional answer to this issue, (3) widening the study of the mortality / environment relationship to all the French... |
