Seasonal spatial distribution of gray seals (Halichoerus grypus) on their haul out sites identified by the ONCFS on the rocks of Portsall in 2010.

Cold-water coral habitat mapping in submarine canyons of the bay of Biscay was realized by the deep sea laboratory of Ifremer. Data came from the BOBECO cruise in the framework of the CoralFish project and as part of an agreement between Ifremer and the Agence des Aires Marines Protégées. The method was based on video and image analyses. Videos and Images were acquired using the ROV Victor 6000 during the BOBECO cruise (from 9/09/2011 to 11/10/2011, chief scientists: Sophie Arnaud-Haond et Anthony Grehan). Observed habitats were defined according to the CoralFish typology (J.S. Davies, B. Guillaumont, F. Tempera, A. Vertino, L. Beuck, S.H. Ólafsdóttir, C.J. Smith, J.H. Fosså, I.M.J. van den Beld, A.

The collection of socio-economic data from professional fishermen makes it possible to calculate economic indicators by fleet segment and contributes in particular to evaluating the economic performance of each fleet and the impacts of the implementation of management measures. It also makes it possible to evaluate the weight of French fishing in Europe, the share of fishing in the national and regional economy as well as the attractiveness of the profession and the impact of cost variations such as the cost of fuel.

The geographical distribution of the main sources of wild Pacific oysters (Crassostrea gigas) (Thunberg, 1793) on the coasts of the Pertuis Charentais was compiled from 2010 to 2012. The inventory focuses on natural foreshore deposits (+ 6-0 m sea coast) and compiles two cartographic sources: 1) quantitative inventories made in 2010 by Ifremer from the Tranche sur Mer (Vendée) to Vaux-sur-Mer in 21 representative sites to estimate wild stocks of Pacific oysters and 2) inventory mapping of intertidal marine habitats mainly made by LIENSs (in cooperation with CREOCEAN, IODDE, Ré Nature Environnement and GEO-Transfert) under the project CARTHAM Natura 2000at sea of the Agency of Marine Protected Areas. Methodologies used by Ifremer to estimate the areas colonized combine thematic analysis in Geographic Information System (GIS) and field validations (Soletchnik et al., 2012). The methodologies used to estimate LIENSs extension of the intertidal habitat of the oysters combined aerial image analysis, remote sensing, field validations and thematic analysis using GIS (Cajeri et al., 2012).
