achievement of an initial state of habitat of Community interest and populations of fish and benthic megafauna on the Natura 2000 site - Orient Seine Bay (Fr2502021). With 2 sections: - section A: benthic habitats, - section B: Fish populations, benthic megafauna and fisheries functionalities. An initial state must be carried out on benthic habitats; it must meet a threefold objective: (i) to assess the conservation status of the habitats on the site, (ii) to carry out the initial state of monitoring the effectiveness of Natura 2000 fisheries management measures according to the BACI approach, and (iii) to specify and update the mapping of habitats on the site. The incumbent will conduct a critical analysis and make recommendations on the monitoring strategy for benthic habitats at the site. An initial state must also be carried out on fish and benthic megafauna using 2 gears (Cp3m and Gov); it will feed the updating of the mapping of habitats on the site (benthic megafauna), to inform the criterion functionalities of the state of conservation of the habitats, to contribute to the initial state of monitoring the effectiveness of fisheries management measures (Baci), to inform the spatio-temporal distribution of migratory amphihaline fish and to feed a critical reflection on the sampling gear to be favored thereafter.
