| The lagoon of Brusc located on the Mediterranean coast (VarFrance) is subjected to climatic and hydrologic particular conditions. The low values observed for nutrient into the sea water affect the evolution of phytoplankton. Thus chlorophyll concentration measured in the lagoon give an annual average of 0.42 mg. m-3 . The growth of two bivalves species : Cerastoderma glaucum and Venerupis semidecussata was compared between two stations where one population of each species are implanted. The culture of this molluscs is made in the lagoon and in outdoor pound dug on the old salt-pan near at hand. In the pound, subjected to natural climatic conditions, a great growth is noted for this two species. The growth rate appear better than the populations of the... |

| Coastal Mediterranean lagoons are often defined as homogeneous ecosystems that home many migratory and sedentary species. They also host strong salinity gradients, depth variation and very diverse plant communities, which create small-scale heterogeneity within lagoons. This is why each lagoon must be described as an entity by itself made up of a multitude of homogeneous features, called habitats, which support specific ecological functions for organisms (nursery, feeding, protection against predators...). Although many studies have resulted in collecting high numbers of physical, chemical and biological data in coastal Mediterranean lagoons, there is currently a lack of knowledge of the spatial distribution of these habitats. In our project, we (1)... |

| Much concern has been raised about the decline in the European eel (Anguilla anguilla) population. European management plans for the recovery of the stock are now in preparation, the main objective being to increase the escapement of the potential spawners (silver eels) in each basin to allow 40% of the pristine biomass to escape. However, there are relatively few studies on silver eel escapement and production, and no recent measurement of escapement in lagoons, habitats which support large silver eel sub-populations in the Mediterranean region. A mark-recapture study was carried out in autumn 2007 in order to estimate the number of silver eels migrating from the Bages-Sigean lagoon in the South-West of France. The migrating population, mostly males... |
