| Rajidae stocks (Raja clavata, Raja brachyura, Raja montagui, Raja microocellata, Leucoraja naevus and Raja undulata) in the English Channel and North Sea (ICES divisions 3a, 4 and 7d) are actually managed as a complex (“skates and rays”) and subject to a single TAC. TAC advices from the ICES are based on scientific survey indices trends from each species. Rajidae catches are mainly bycatch from flatfish fisheries such are sole (Solea solea) and plaice (Pleuronectes platessa) fisheries. Furthermore, because of their top predator position as well as their life history, Rajidae are species sensitive to overfishing. These different factors have led to a revision in stock assessment methods. ICES classified Rajidae as category 3 data limited stocks. The lack of... |

| The SELEDRAG project was conducted in French territorial waters in May 2019. It was a short project, lead by the CNPMEM (French National Committee for Marine Fisheries), with Ifremer as scientific partner, and funded by “France Filière Pêche”. The context of the project is the French King Scallop fishery in the Eastern Channel, where 720 fishing boats are directly concerned by this species. Despite its importance, there is very little management for this species at the European level, but several binding rules for French fishermen in order to protect the stock, are not applicable to other countries. One of the French specificity is the ring size used, 92mm for all Scallop fisheries in France vs 85mm (or less) for UK fisheries. Another sharp divergence is... |

| The main aim of King scallops Pecten maximus stock assessment French surveys in the Bay of Seine (COMOR) is to set an annual primary diagnosis of the state of the resource (abundance by age classes, growth, distribution on the seabed) before the opening of the fishing season. For twenty years, the survey takes place in July, best compromise between enough growing of the group 1 shells, faster in the Bay of Seine than in the Saint-Brieuc Bay, allowing their capture by sampling dredges, and early expertise which allows to stakeholders (administrative, market organization, professional committee, ...) to take the best measures suited to the reality perceived through the survey’s results. The results are presented in distinguishing the off-shore part of the... |

| In this paper we used a modelling approach integrating both physical and biological constraints to understand the biogeographical distribution of the great scallop Pecten maximus in the English Channel during its whole life cycle. A 3D bio-hydrodynamical model (ECO-MARS3D) providing environmental conditions was coupled to (i) a population dynamics model and (ii) an individual ecophysiological model (Dynamic Energy Budget model). We performed the coupling sequentially, which underlined the respective role of biological and physical factors in defining P. maximus distribution in the English Channel. Results show that larval dispersion by hydrodynamics explains most of the scallop distribution and enlighten the main known hotspots for the population,... |

| The results of a survey on fishers' perceptions of recent changes in the eastern English Channel ecosystem carried out in 2006 were compared with fishery and bottom-trawl survey data. A hypothesis-testing framework was used, testing the null hypothesis that fishers' statements were true, which permitted evaluation of both agreement and disagreement. Overall good agreement between fishers' statements and scientific data was found, and both sources suggested that the fish community in the Channel is undergoing large changes, among which are decreases in some commercially important species; in addition, a number of human pressures impact the ecosystem. Fishers had an accurate perception of changes and their time-frames, but not necessarily of their causes.... |

| The impact of King scallop dredges on benthic communities in the Bay of Seine has been studied through the analysis of benthic species associated to King scallops collected during the stock assessment surveys between 1998 and 2011 on the one hand, and on the other hand on the trends of fishing effort during the same period. The aims of this study is in a first step to draw a partial picture of the state of benthic communities in the Bay of Seine and in a second step to assess if changes in these communities could have been caused by changes in the activity of dredging. The analysis of the benthos species allows us to highlight the evolution of the abundance and spatial distribution of 17 species of benthic macrofauna. The abundance of most of these species... |

| The COMOR scientific cruises are aimed mostly at assessing directly the king scallop stock in the Seine Bay (listed deposit) and in the area located north of the listed deposit, and baptised "Proche Extérieur" (Close Outside). The assessment is based on a stratified random sampling scheme, each dragging accounting for one sample unit. The collected data enables the valuation of the abundance indexes par age class and area, the biomass available on each area, the demographic structure of the population, and the distribution of the population on the seabed.

| This scientific report describes the sea cucumber (Cucumaria frondosa) fishery in Saint-Pierre and Miquelon (France). A synthesis of knowledge on the biology and life cycle of this species is presented, as well as a history of the fishery. Using the data collected during the SPM2017-Hal scientific survey conducted in August 2017, as well as data from the professional fishery, both in Saint-Pierre and in Canada, an assessment of the sea cucumber stock and a diagnosis of the state of this stock are carried out. Management objectives for this stock, with a view to its sustainability, are proposed. |

| The King scallop Pecten maximus constitutes the first landed species in terms of tonnage and the second or third one in terms of value for the French fisheries. More than 90% of these landings come from the English Channel indicating that its exploitation is essential to local fleets. The COMANCHE project (Ecosystem Interactions and anthropogenic impacts on King scallops populations in the English Channel) proposed to improve the knowledge of the scallop within the Channel, through an ecosystem-based approach for fisheries, appealing to a wide range of scientific disciplines (physics, chemistry, genetics, ecology, geostatistics, modeling, economics ....). Researches on the spatial location of scallop beds, connectivity by larval dispersal between beds,... |

| Among the English Channel fishery, the importance of cuttlefish stock has increased, following the cephalopods global landings and market trend. The stock is currently managed at regional scale but not by European regulations, although it is a shared species targeted by French and British fishing fleets at several stages of its life-cycle and across much of its distributional range. An assessment of this stock was conducted in June 2014 by fitting a two-stage biomass model on a 22 years’ time-series (1992-2013). As the assumptions of the model are based on a simplified life-cycle, it would be appropriate to compare the results with outputs from other models in order to obtain reliable biomass estimations. The final aim is to produce reliable management... |

| Au cours de la campagne d’évaluation du stock de coquilles Saint-Jacques Pecten maximus de la baie de Seine (COMOR39) réalisée en juillet 2009, l’Ifremer a procédé sur la zone d’étude identifiée pour une future implantation d’éoliennes off-shore au large du Calvados à un sur-échantillonnage visant à obtenir une image précise de la population présente sur cette zone. Une comparaison avec la population présente à l’échelle de l’ensemble du gisement classé de la baie de Seine est effectuée. Ce rapport de diffusion libre a vocation à être transmis à l’ensemble des opérateurs concernés par le projet. |
