| The ecosystems exploited by fishing are complex. The species which are sought after and their distribution rely on numerous processes, in time and space. The understanding of marine ecosystems requires important means and diverse information including those of professional fishing and scientific cruises. At first, scientific fishing cruises aimed to explore marine fauna and discover new halieutic resources. They were in line with the exploration cruises carried out by Prince Albert 1st of Monaco at the end of the XIXth century. However, since the beginning of the 1970s, they have been focusing on the quantification of the resources exploited by fishing. [...] After a series of "Understanding keys" aimed at helping the reader understand the methodology and... |

| Whatever their geographical or political point of view, Sea and coastal strategies highlight an “abyssal need” for knowledge and frequently call for a reinforcement and a better valorization of research in Marine Sciences and Technologies (MST). But, when a French public research resources inventory is needed, in the perspective of constructing a consistent action plan, we lack a framework to define thematic and disciplinary perimeter to be taken into account, to identify available data, to choose practical evaluation or estimation methods. The following study is a proposal to answer these questions. The methodology is mainly based on data collected by French High Council for Evaluation of Research and Higher Education (Hcéres) and completed by an inquiry.... |

| Since about twenty years, Ifremer have carried out fishery surveys along the French coasts. A dynamic indicator-based approach to the assessment of multi-stock fisheries has been applied to these data series. Reference points for non-commercial populations and community indicators are seldom available, but reference directions are well established: it is known whether fishing will increase or decrease the indicator, hence the direction that should be avoided. A set of simple indicators of fishing impacts on fish populations and communities were estimated from time-series data provided by scientific surveys (population abundance and average length, community total biomass and number, average length and weight, and size spectrum). Trends in these indicators... |

| Forest fire is an important issue in New Caledonia. During the dry season, forest fire can remove vegetation from large areas (from 10 000 to 30 000 ha per year on average), leaving metal-rich soils uncover and more exposed to runoff. The impact of forest fires on the chemical and microbiological quality of water has been poorly studied in New Caledonia, either for river water bodies or coastal lagoon water bodies. The purpose of this document is to review the current knowledge on forest fires impacts on water quality that has been documented in the worldwide literature, a topic of increasing importance in the context of global warming. |

| La surexploitation des ressources halieutiques a conduit à une crise majeure du secteur de la pêche professionnelle. Dans ce contexte, les pêcheries artisanales, et notamment les pêcheries aux petits métiers côtiers, apparaissent comme des modes d’exploitation potentiellement durables des ressources côtières. La diversité des engins utilisés et des espèces ciblées rend néanmoins complexe le suivi de cette composante importante de la pêche professionnelle. L’activité de pêche artisanale reste ainsi très peu évaluée en Méditerranée, et notamment à l’échelle d’une Aire Marine Protégée (AMP). Les AMP sont pourtant de plus en plus utilisées comme des outils de gestion de ces pêcheries, les effets des différentes mesures de gestion mises en place étant à même de... |

| Parmi les recommandations du programme de surveillance de la DCSMM, le suivi des poissons et céphalopodes démersaux des milieux meubles côtiers a été jugé prioritaire. Un suivi pérenne et opérationnel doit ainsi être mis en place au cours du premier cycle (2014-2020), il est basé sur une série de campagnes récurrentes à déployer dans les fonds inférieurs à 40 mètres, en complément de celles déjà existantes sur les façades Manche et Atlantique (Nurse, Nourseine, Noursom). Les suivis sont opérés dans les zones de nourriceries côtières des poissons bentho-démersaux, constituant des habitats essentiels pour de nombreuses espèces marines. La caractérisation de l’état écologique des peuplements et l’étude de la fonctionnalité des habitats de nourriceries... |
