Última Cartographie synthétique et analyse des peuplements benthiques sur deux secteurs du littoral français "Manche-Est" et "Loire-Gironde" ArchiMer Blanchard, Michel; Heim, Marie; Rozec, Xavier; Caisey, Xavier. This document presents a synthetic study of benthos in two large areas of the French coast: East-Channel and the area between Loire and Gironde. This original synthesis stocktakes biotopes maps published for the vast majority in the 70’s. The report uses the previous descriptions and analysis done by the different authors, and translates them with present specific names or biotopes codes, as proposed in the European EUNIS referring system. The presented maps are standardized and referred geographically with WGS84 to be collated together. For each biotope, specific richness and ecological richness are analysed, thanks to the information given by the various authors. Some informative cards of the main representative species are also presented in the...

A beam trawl survey of the Bay of Vilaine was conducted from 1981 to 1997. Changes in the commercial fish community were analyzed by comparing the characteristics at the year and decadal scales. The community structure and nursery function of the Bay were steady during the period. However, specific richness, assiduity and distribution indices demonstrated a reduction in the second decade. The global abundance fell from 105.8 ind.ha-1 to 31.3 ind.ha-1. This trend was less marked for the external more marine stratum, which exhibited the lowest densities. The results are discussed in terms of ecological meaning of such a community, compared with the overall demersal fish community. The reasons of the decrease are questioned regarding nursery habitat, local...
