The eastern English Channel, which connects the Atlantic Ocean to the North Sea through the Dover Strait, is an area where numerous and often conflicting human activities take place. A cross-border multidisciplinary project called CHARM was initiated to provide knowledge and tools for planners and decision-makers to durably manage the shared marine living resources. One such tool was an atlas of fish spatial distributions and modelled habitats, which was used here to investigate ontogenic and seasonal shifts in fish spatial distribution and habitat through a case-study, the dab Limanda limanda. Survey data for several life-history stages (eggs, larvae, coastal nurseries, < and > 1 year old) and seasons were used to map spatial patterns (using...

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.

Coupling hydrodynamic and individual-based models to simulate long-term larval supply to coastal nursery areas ArchiMer
Rochette, Sebastien; Huret, Martin; Rivot, Etienne; Le Pape, Olivier.
For many marine fish species, recruitment is strongly related to larval survival and dispersal to nursery areas. Simulating larval drift should help assessing the sensitivity of recruitment variability to early life history. An individual-based model (IBM) coupled to a hydrodynamic model was used to simulate common sole larval supply from spawning areas to coastal and estuarine nursery grounds at the population scale in the eastern Channel on a 14-yr time series, from 1991 to 2004. The IBM allowed each particle released to be transported by currents from the hydrodynamic model, to grow with temperature, to migrate vertically giving stage development, and possibly to die according to drift duration, representing the life history from spawning to...

Evaluation du stock de coquilles Saint‐Jacques Pecten maximus de la baie de Seine. Résultats de la campagne scientifique COMOR 2019 (2 au 20 juillet 2019). ArchiMer
Foucher, Eric.
The assessment of the King scallop stock of the Bay of Seine (Pecten maximus) was carried out in July 2019, in the Bay of Seine sensu stricto, located in French territorial waters (from the Normandy coast to the south to the limit of 12 nautical miles to the North), as well as the bordering zone lying north of this 12-mile limit and up to a latitude of 49°48N to the North, called "Extérieur Baie de Seine". For this, a scientific survey, based on a stratified random sampling plan, was conducted aboard the F/R Thalia, a coastal research vessel of the French Oceanographic Fleet. Nearly 170 sampling points were completed in the whole area. Analysis of these data leads to an overall increase in exploitable biomass over the entire area. Outside the Bay of Seine,...

Les campagnes d'évaluation du stock de coquilles Saint-Jacques en Manche orientale : méthodologie et estimation des indices d'abondance ArchiMer
Vigneau, Joel; Fifas, Spyros; Foucher, Eric.
The methodology used for obtaining absolute abundance indices for Eastern Channel scallop is described in this paper. For the survey (COMOR), stratified multi-stage random sampling is used. The number of sampled units is computed based on variance estimates from the last survey. Knowledge of gear (Brittany dredge with a diving plate) selectivity and efficiency parameters is required for estimating total exploitable biomass and absolute abundance indices by age and strata. Details of the mathematical development of all estimators are given. A non parametric bootstrap provides confidence intervals for all estimates.

Relative contributions of different sole and plaice nurseries to the adult population in the Eastern Channel: application of a combined method using generalized linear models and a geographic information system ArchiMer
Riou, Philippe; Le Pape, Olivier; Rogers, Stuart I..
The Eastern Channel (ICES division 7d) is considered a unit for stock management of the common sole Solea solea and the plaice Pleuronectes platessa. At this scale, the aim of this work is to model the juvenile distribution of these flatfish. The database used, based on different surveys undertaken during the two last decades, includes 4500 coastal beam trawl hauls throughout the Eastern Channel coasts. Multivariate analyses are used to study the interannual fluctuations in flatfish recruitment of the region. This approach allows us to separate the Eastern Channel into homogeneous sectors with regard to these fluctuations. The physical parameters that contribute to the observed juvenile sole and plaice distributions are identified and their distributions...
