| The Marennes Oléron Bay, the main French oyster culture basin, is an estuarine zone which is subject to anthropic pressure. Meteorological parameters such as temperature, insolation, pluviometry determine, for the most part, the water temperature and salinity conditions for each season and control the nutrient fluxes, as well as the primary and secondary production of the basin. The average air temperature (Météo -France) stays around 12.5°C between 1950 and 1980, then rises more than 1°C in 20 years. In those 50 years, average insolation drops from 198 hours to 176 hours, corresponding to an 11% decrease. Seasonal distribution of water inputs shows that spring pluviometry increased by 30% between the 1950's and the last two decades. Precipitations also... |

| The "Artificial reefs" and "Repopulating" issues have been tackled by the Ifremer for a number of years without reaching a clear cut point of view, mainly for lack of socio-economic elements necessary to a rigorous analysis of these devices and practices. During a mission in Japan in January 2006, some Japanese experts, have presented to the head of the Ifremer a few examples of realisations related to these fields and conducted in their country. The head of the Ifremer realised the scope of such devices in Japan and expressed the wish to see an in-depth study carried out over there. In this purpose, the International Relationship Department organised and co-financed the three-month stay in Japan of a student from the University of Montpellier III, Sylvain... |

| The scientist community, the fishing organisations and all involved parties show a growing interest in an integrated project management of the sea space exploited by fishing communities. A key to reach such a target is to make available reliable and precise scientist data on the different components of the fishing systems. For about twenty years, and in its mission to support the development of an integrated management for a sustainable use of marine resources, Ifremer has been organising monitoring campaigns of fishery resources along the shores of France. These campaigns aim at providing abundance indicator on species of interest. They consequently provide an essential knowledge base to characterize and trace the status of exploited fish and... |

| The integration of fishing management into the ecosystemic approach has been recommended for many years by international consultative bodies; it is also written into international conventions and agreements. The implementation of the ecosystemic approach involves the development of programmes for monitoring exploited ecosystems in order to measure the effects of management steps. Plotting the results of these observations for operational reasons requires formalizing summary performance indicators. IFREMER has carried out halieutic observation campaigns for some twenty years along the coasts of France from oceanographic ships and chartered ships. The objective of these campaigns is to produce abundance indices of species that are of halieutic interest.... |

| Initiated in 2013, the present work carried out in 2014 extends the monitoring network focusing on marine invasive exotic species in Saint-Pierre and Miquelon archipelago. In a global context of coastal ecosystems’ changes, accentuated by direct or indirect effects of human activities, it became essential to implement a monitoring survey and to track the expansion of marine invasive species along Saint-Pierre and Miquelon shoreline. Fukui traps and tunicates collectors deployed on different stations as well as the timely completion of observational dives, have provided the following conclusions: several invasive species were again reported within the local marine ecosystem. Those species, i.e., Carcinus maenas, Caprella mutica, Ciona intestinalis,... |
