| The study of variations in the concentration of heavy metals inside a tank filled with the water of a neighbouring lagoon has been carried out since August 1977•The analysis concerned a lagoon station and the bath built for ECOTRON program, closed to this lagoon. They deal with water, molluscs and the sediment. Inside the lagoon station, the tested molluscs are Prosobranch Gastropods : Trochocochlea carinata and inside the basin, cockles : Cerastoderma glaucum. The results point out that the concentration of these heavy metals vary with the tissue in relation with physical and chemical medium parameters, and it can be particularly observed a significative correlation between both the whole concentration of these elements inside the sediment and the... |

| A checklist of macroalgae in Thau Lagoon (Herault, France), based on literature records and new collections, is given. Using present-day taxonomy, 196 taxa and stadia of macroalgae have been identified to date. Sixty of these were no longer found in the samples, 36 were new to the lagoon, and the taxonomic identity of 15 species was amended. Twenty-five new introduced taxa were identified, giving a total of 45 introduced macroalgae for the flora (23% of total). Among these, 17 taxa and several genera (Acrorhrix, Chondrus, Dasysiphonia (?), Prionitis) are new to the Mediterranean Sea and 12 are new to Europe. The majority (43 taxa) may originate from the Pacific region, having arrived either directly or via other aquaculture sites. A highly probable vector... |

| Bringing together France, Italy and the Principality of Monaco since 1976, the RAMOGE agreement is born of an awareness of the pollution of the sea. Its aim is to raise public awareness, develop actions and make recommendations for the preservation of the marine environment. In 2015, an exploration campaign of the deep zones of the RAMOGE area made it possible to acquire new data in the Natura 2000 sites of "Corniche Varoise" and "l'Estérel", as well as on other Italian and Monegasque sectors. . The RAMOGE project "exploration of deep zones of ecological interest" is based on 3 phases. Each country is invited to become involved in the implementation of one of these phases. After Italy in 2015, which facilitated the provision of nautical resources for... |

| Mud blisters related to the Parasite worm Polydora or to the presence of TBT in the Thau Basin waters depreciate the market value of the oysters produced in this lagoon. A solution to this problem was searched by immersing during 1 to 3 months the oysters in the open sea before being marketed, this shell improvment operation being called "affinage en mer". The objective or this study carried out over 2,5 months in automn '1991 was to quantify possible differences, biometrical or biochemical, between oyster immersed for "affinage" on bottom open-sea structures, or remained for a normal cultivation .in the Thau lagoon. No significant differences were measured, although the external aspect of shells was modified for open sea oysters. Complementary studies at... |

| "Small trades" refers to the body of fishing boats, excepting the trawlers, which have a trawling license and the tuna/sardine boats, which have a pelagic fishing license. The ships that fish for small pelagic fish by using a lamp are only included for the other trades they ply, if applicable. Whereas certain "small trades" work offshore, the majority of them exploit the lagoons and coastal area. The importance of the coastal areas in general, where a large number of biological and ecological processes are being developed, need no longer be demonstrated: A large part of primary and secondary production takes place in these areas, which host moreover many reproduction and nursery sites for a great many species. "Small trade" fishing is one of the main... |

| In the context of WFD implementation on Mediterranean lagoons, work has been carried out since 2010 by Ifremer, Tour du Valat and IRSTEA (Onema and AERM & C fundings), to assess the relevance of macrophytes and macrofauna indicators for oligohaline and mesohaline lagoons (mean salinity <18 PSU). The question of the relevance of indicator metrics and thresholds for the "phytoplankton" biological quality element also arises, especially due to the confined nature of olgo-mesohaline lagoons. The objective of this study is to characterize the abundance and composition of phytoplankton on 5 oligo and mesohaline lagoons of the French Mediterranean coast (Scamandre, Crey, Charnier, Bolmon and Grand Palun). Analyses of accessory pigments (chlorophyll and... |
