Résumé : This document presents a survey of the sea-related activities in France, i.e. those of the commercial sector (exploitation of mineral and living resources, manufacturing industries, services) and those of the non-commercial public sector (Navy, State services, education, safety, marine research). A chapter is devoted to the protection of the coastal and marine environment. Each activity of the commercial sector is described by key-figures (turnover, value added, employment); the description of the non-commercial public sector includes data on costs, including personnel costs. In addition to these figures, qualitative information is given on the recent development, present situation and future prospect of each activity. This set of data and information makes it possible for the reader to assess the significance of the sea-related economy and the relative weights of its various components.
Ce document présente un panorama des activités liées à la mer en France, c'est-à-dire celles du secteur marchand (exploitation des ressources minérales et vivantes, industrie manufacturière, services) et celles du secteur public non marchand (Marine nationale, services de l'État, enseignement, sécurité, recherche marine). Un chapitre est consacré à la protection de l'environnement littoral et marin. Chaque activité du secteur marchand est décrite par des chiffres-clés (chiffre d'affaires, valeur ajoutée, emploi); pour le secteur public non marchand, sont fournies des données sur les coûts, notamment les coûts de personnel. Ces indicateurs sont accompagnés d'informations qualitatives sur l'évolution récente, la situation actuelle et les perspectives de chaque activité. Cet ensemble de données permet au lecteur d'apprécier l'importance de l'économie maritime et le poids relatif de ses différentes composantes.

Résumé : Implementation of ecosystem-based approaches to marine management points to several shared objectives between conservation and fishery management that require better knowledge of the life history of the exploited resources, elucidation of the information encoded in the calcified tissues (otoliths, scales, bones, shells, and corals) of marine and freshwater organisms, and support for knowledge-based, sustainable ocean management and use. Calcified tissues have been employed since the 19th century to gain knowledge of life traits, population structure, and environmental relationships of fish and molluscs. Breakthrough advances include the discovery by Pannella (1971) of the daily growth increments and the discovery by Radtke (1984) of otolith tracer approaches, resulting in an exponential growth of publications and four dedicated international symposia. IOS2014 will be the fifth in a series of independent symposia convened since 1993, to encourage the exchange of information and expertise, and promote the development of new techniques and applications for otolith-based analysis in ecology, management, and conservation. This international forum is the centre for the exchange of information on developments in the field. New techniques of analysis, statistical treatment, and indeed new areas of application are all presented in this forum. The IOS series started in Hilton Head (USA) in 1993, followed by IOS1998 in Bergen (Norway), IOS2004 Townsville (Australia), and the IOS2009 Symposium held in Monterey (USA). In general, attendance ranged between 250–350 participants. IOS2009 counted 268 registrants from 36 countries, despite the economic crisis.

Résumé : International audience
Estrogens and progestins are widely used in combination in human medicine and both are present in aquatic environment. Despite the joint exposure of aquatic wildlife to estrogens and progestins, very little information is available on their combined effects. In the present study we investigated the effect of ethinylestradiol (EE2) and Levonorgestrel (LNG), alone and in mixtures, on the expression of the brain specific ER-regulated cyp19a1b gene. For that purpose, recently established zebrafish-derived tools were used: (i) an in vitro transient reporter gene assay in a human glial cell line (U251-MG) co-transfected with zebrafish estrogen receptors (zfERs) and the luciferase gene under the control of the zebrafish cyp19a1b gene promoter and (ii) an in vivo bioassay using a transgenic zebrafish expressing GFP under the control of the zebrafish cyp19a1b gene promoter (cyp19a1b-GFP). Concentration-response relationships for single chemicals were modeled and used to design the mixture experiments following a ray design. The results from mixture experiments were analyzed to predict joint effects according to concentration addition and statistical approaches were used to characterize the potential interactions between the components of the mixtures (synergism/antagonism). We confirmed that some progestins could elicit estrogenic effects in fish brain. In mixtures, EE2 and LNG exerted additive estrogenic effects both in vitro and in vivo, suggesting that some environmental progestin could exert effects that will add to those of environmental (xeno-)estrogens. Moreover, our zebrafish specific assays are valuable tools that could be used in risk assessment for both single chemicals and their mixtures. © 2016 Elsevier Inc.

Résumé : Aquaculture is an important part of the Common Fisheries Policy. Indeed, the Community incentives policy for the farming of sea or fresh water fish, shellfish and molluscs must contribute to supplying the Common Market with fisheries products and to reducing the chronic negative trade balance in this area. The collection of statistics on the economic and social aspects of Aquaculture in the European Community is not a straightforward process. [NOT CONTROLLED OCR]
