| 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... |

| The sea bass, Dicentrarchus labrax, has been subjected to intensive aquaculture on the Mediterranean cost for ten years. Marine fish hatcheries are key factors in the aquaculture field, and face different pathologies, especially one of viral origin (nodavirus) that could challenge their feasibility. Consequently, we have tried to provide some data on larvae and spawning stocks. Firstly, we have studied the immunoglobulins, components of the specific humoral immunity, and their role as antibodies. On adult basses, these immunoglobulins are tetrameric molecules with high molecular weight (850 kD), made of heavy (H) - 80 kD and light (L) - 26 kD chains. In the eggs, simplest forms such as monomeric or dimeric are brought to the fore; they are located under... |
