The eastern English Channel, the narrow channel of water separating northern France and southeast England is an area of intense human use of the array of resources concentrated into its relative small area. The vulnerability of living resources and their habitats brought together French and British maritime experts within a common project (called CHARM): to create an atlas of marine resource habitats in the eastern English Channel so as to provide planners and decision-makers with the necessary information to help managing the use of its living and non-living resources. This multidisciplinary and richly illustrated atlas provides abundant information on the legal framework and physical environment; benthic invertebrates, fish and their habitats; fishing... |

The community structures and succession of phytoplankton, protozooplankton and copepods were studied from February 2007 to July 2009 in a coastal area of the eastern English Channel subject to Phaeocystis globosa blooms. While diatom blooms preceded P. globosa blooms each year, the community structure and stock of heterotrophic protists appeared to be related to the dominant P. globosa life cycle stages. In 2007, the dominance of large colonies (> 100 mu m, up to 316 mu g C L(-1)), which resulted in a high biomass of healthy free cells (up to 132 mu g C L(-1)), accompanied high spirotrich ciliate stocks (up to 58 mu g C L(-1)) and high abundances of the copepods Acartia clausi and Temora longicornis (up to 11 ind. L(-1)). In 2008, the bloom which lasted... |

In the present study, the histological-based condition of common sole (Solea solea) larvae in the English Channel was evaluated to assess the relevance of experimentally-calibrated indices for wild collected specimens. Based on topographical observation of foregut, midgut, hindgut, liver and pancreas, each of the 202 larvae analysed was attributed one of the six grades of a condition index that was developed for sole in the nineties. In parallel, a synthetic table of 20 criteria historically used as condition indicators was created from an extensive review of the literature. These criteria were related to tissular integrity, cells height, nuclei, presence of prey and vacuolisation of the same five target organs. For each larva, each criterion was scored on... |

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.... |

In the past decade, systematic conservation planning tools have been increasingly and successfully used to set spatial conservation plans that meet quantitative protection targets while minimizing enforcement and socioeconomic costs. However, when applied to fisheries, systematic conservation planning fails to account for (1) changes in fleet dynamics induced by new conservation constraints and their associated feedbacks on conservation costs or (2) their influence on fish population dynamics and distributions, which may in turn alter the achievement of conservation targets. Such a static approach may therefore lead to short- or medium-term misestimates in forecasted costs and target achievements. In order to circumvent such limitations of systematic... |

From Normandy to Belgium bordary, the coastal fishery became during the ten last years a significant social and economic actor, which mostly lives by predominant exploitation of Eastern Channel. Recently discovering a situation of resource overexploitation and a difficult cohabitation between "metiers", these coastal fleets are in the heart of various preoccupations of managment at regional, national and european levels. Since 1985, a coordinated programme (including Boulogne and Ouistreham) allowed to progress in the knowledge of complex fisheries through : improvement of statistics, characterisation of coastal fleets and their activity, asses-ment of the knowledge on the resources.This synthesis describes, for 1987-1988, the quality of the regional... |

The link between harmful algal blooms, phytoplankton community dynamics and global environmental change is not well understood. To tackle this challenging question, a new method was used to reveal how phytoplankton communities responded to environmental change with the occurrence of an harmful algae, using the coastal waters of the eastern English Channel as a case study. The great interannual variability in the magnitude and intensity of Phaeocystis spp. blooms, along with diatoms, compared to the ongoing gradual decrease in anthropogenic nutrient concentration and rebalancing of nutrient ratios; suggests that other factors, such as competition for resources, may also play an important role. A realized niche approach was used with the Outlying Mean Index... |

Considerable research has been conducted in the past 15 years around the Eastern English Channel ecosystem. Data collected since the 1970s on the biotic and abiotic compartments have been collated and mapped out in the mid-2000. This spatially explicit information formed a sound basis to improve knowledge on, and model, the functioning and dynamics of key ecosystem compartments, with a focus on flatfish species and fisheries and their interactions with other sectors of activity (aggregate extractions, maritime traffic). The more recent ongoing works are dedicated to the integration of those processes into several complementary end-to-end ecosystem models. |

Asthenognathus atlanticus Monod, 1932, has been reported for the first time from the eastern part of the Bay of Seine (eastern English Channel). A total of 30 specimens were collected between the years 2008 and 2011, along the Normandy coast from Ouistreham to Antifer, mainly on mud and muddy sand habitats, between 10 and 25 m depth. The distribution range of A. atlanticus has been previously known to cover eastern Atlantic coasts from Angola to the western English Channel, where it reached its northern limits. It is also present in the western part of the Mediterranean Sea. The changes in the sediment composition of the eastern Bay of Seine have probably led to the development of a potentially favorable habitat for this species. However, the data... |
