Campagnes expérimentales de chalutage en Manche orientale. Les campagnes C.G.F.S. 1997 & 1998 ArchiMer
Carpentier, Andre; Coppin, Franck.
lfremer carries out a yearly bottom trawl survey named Channel Ground Fish Survey (CGFS) in order to collect essential biological data on major exploited fish species in the Eastern Channel. These data are also provided to feed the indispensable historie series to the yearly assessment of resources. This report presents results of the CGFS surveys for 1997 and 1998, under two aspects: a multispecific approach of the biological assemblages and integrating an interannual analysis, then a monospecific analysis of 7 species of commercial interest, as whiting, pout, cod, red gurnard, plaice, black bream, red mullet.

Contribution à l'étude de la biologie des populations de Tacauds Trisopterus luscus (L.1758) en Manche orientale et dans le sud de la Mer du Nord ArchiMer
Desmarchelier, Manuela.
L'étude est axée principalement sur la reproduction, la croissance du Tacaud (Trisopterus luscus L.), ainsi que sur la répartition des individus à l'intérieur de la zone étudiée. Le Tacaud, poisson, gadidé, est une espèce côtière péchée artisanalement comme espèce accessoire. Les jeunes vivent à la côte; les adultes sont sur des fonds chalutables, à l'exception des plus âgés qui migrent sur des fonds rocheux. Notre étude a été réalisée à partir de chalutages expérimentaux et de l'analyse statistique des captures débarquées au port de Boulogne/mer. Le rythme de la reproduction a été déterminé, ainsi que l'âge et la taille à la première maturité sexuelle. On observe un décalage géoqraphique de la reproduction : Les populations vivant au nord mûrissent plus...

Spatial analysis of the trophic interactions between two juvenile fish species and their preys along a coastal-estuarine gradient ArchiMer
Kopp, Dorothee; Le Bris, Herve; Grimaud, Lucille; Nerot, Caroline; Brind'Amour, Anik.
Coastal and estuarine systems provide nursery grounds for many marine fish species. Their productivity has been correlated with terrigeneous inputs entering the coastal-estuarine benthic food web, thereby favouring the establishment of fish juveniles. Studies in these ecosystems often describe the nursery as a single large habitat without verifying nor considering the presence of contiguous habitats. Our study aimed at identifying different habitats based on macrozoobenthic communities and morpho-sedimentary characteristics and assessing the trophic interactions between fish juveniles and their benthic preys within these habitats. It included 43 sampling sites covering 5 habitats in which we described taxonomically and quantitatively the invertebrates and...
