| Ce rapport fait la synthèse des travaux réalisés en 2008 et en 2009 au cours du programme Selecmer. Celui-ci, réalisé à l'initiative des professionnels de la pêche en partenariat avec l'Ifremer, avait pour objectif de travailler à améliorer la sélectivité du chalut de fond qu'ils utilisent afin de diminuer les rejets des individus hors-tailles1, en particulier pour le merlan, tout en limitant les pertes commerciales immédiates. Une première phase a consisté à tester l'efficacité de fenêtres à mailles carrées. La deuxième phase a eu pour objectif de développer une grille sélective. Des essais en bassin et des campagnes vidéo en mer ont permis d'apporter des ajustements aux dispositifs sélectifs. L'ensemble des essais de sélectivité à bord des navires de... |

| Three cruises on the Wight-Cherbourg transect were undertaken during the FluxManche II Programme in order to study the origin, nature and behaviour of organic matter inputs to the waters of the English Channel. Suspended particulate material (SPM) collected from surface and deep waters at each station was analysed at elemental level for Particulate Organic Carbon and Particulate Organic Nitrogen (POC, PON), at molecular level for main classes of organic compounds using Pyrolysis-Gas Chromatography coupled with Mass Spectrometry (Py-GC-MS) and for phenolic compounds, particularly lignin-derived phenols, using High Performance Liquid Chromatography (HPLC). The SPM content increases from the French (south) to the English coast (north) with the lowest values... |

| The aim of this work, which was done as a Doctorate of Philosophy (Phd), was to collect the information necessary to help improve the management of the western Channel spider crab stock. The fîrst section présents the main aspects of spider crab population biology. As well as contributing our own results on spider crab habitat, stock density, démographie structure, growth and mortality estimâtes, migrations, reproduction and recruitment, a synthesis is included of the existing scientific literature. The second section on exploitation covers various features of the fishery : its history, fishing methods, fleet structure, spatial and seasonal distribution of fishing efforts in 1986, trends in the landings, fishing effort and catch per unit effort,... |

| This work is the result of collaboration between the English, French, Channel Isles and Belgian laboratories which are involved in a study of the English Channel. Its subject is the activities of fleets and their interactions, and it complements other work on the biogeographical identification of Channel fish and shellfish stocks (published), and on modelling the fleets' interactions as they exploit theresources (in preparation). The concept of a metier is defined as being the use of one fishing gear to catch one or several species targeted during a particular season in a given area. On this basis, 74 metiers were identified during 1989-90. For each metier we give a brief description of the catching gear, the target species and most usual by-catch, the... |
