| Les missions réalisées fin 2004 et début 2005 ont permis de faire le point sur les coopérations potentielles entre l'INSTM et l'IFREMER. Un certain nombre de domaines de coopération et de sujets de collaboration ont été identifiés et se sont traduits (ou se traduiront) par des actions de coopération (missions, stages, formations) soutenues financièrement par le SCAC de l'Ambassade de France à Tunis. La coopération entre l'IFREMER et l'INSTM dans le domaine de l'aquaculture a été très active dans le cadre du programme« Aquaculture 2001 » (1997-2001). Depuis cette période les relations se sont limitées à la préparation du programme DORAD qui était la suite d' «Aquaculture 2001 » . En l'absence du financement FSP sollicité pour DORAD, les deux organismes ont... |

| The study of 41 samples, which were perfomed in the Loire and Vilaine estuaries, during elver fishing seasons 1979-80 and 1980-81, allowed us to define a rapid method of sample analysis in laboratory. The fish catches of one-year old and over were not abundant (eel, mullet, sprat, flounder, sole); on the other hand, larval stages of herring, flounder and also of mullet, sole and sprat were caught in large quantities. In addition, there were numerous catches of brown shrimp and species of trophic interest such as goby and macroplanktonic crustaceans. It is noteworthy that the by-catches are numerous during the fishing season. |

| In view of the European Union (EU) requirements to diagnose and monitor the ecological status of estuarine ecosystems using fish-based indicators, we assessed the effect of the sampling protocol in meeting these objectives. Using three different sampling surveys, we evaluated the impact of four components, i.e. sampling gear, spatial extent, length of time series and temporal window analysed, on the detection of ecological trends in the Gironde estuary, estimated by different types of fish-based indicator. For each component, temporal trends of several fish-based indicators were analysed and for the final diagnosis these temporal trends were combined. The results showed that sampling gear had significant effects on the assessment of ecological trends, as... |

| Estuarine areas are sites of human pressures and degradation. In order to maintain and/or restore the quality of estuarine ecosystems, it is necessary to describe their structure and functioning. For that reason, many recent scientific works focus on food webs, which are depicted as being good indicators of the functioning of aquatic ecosystems. Hence it is necessary to question how estuarine food webs can be described. This paper proposes a pragmatic and practical review of the most widely used techniques (stomach/gut content analysis, stable isotope ratios and biochemical markers) with emphasis on their main advantages, drawbacks and bias according to possible ecological goals (ecological quality objectives). These approaches, although quite different,... |
