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...

PERSEUS project aims to identify the most relevant pressures exerted on the ecosystems of the Southern European Seas (SES), highlighting knowledge and data gaps that endanger the achievement of SES Good Environmental Status (GES) as mandated by the Marine Strategy Framework Directive (MSFD). A complementary approach has been adopted, by a meta-analysis of existing literature on pressure/impact/knowledge gaps summarized in tables related to the MSFD descriptors, discriminating open waters from coastal areas. A comparative assessment of the Initial Assessments (IAs) for five SES countries has been also independently performed. The comparison between meta-analysis results and IAs shows similarities for coastal areas only. Major knowledge gaps have been...

Atlas des Habitats des Ressources Marines de la Manche Orientale - CHARM II ArchiMer
Carpentier, Andre; Coppin, Franck; Curet, Lucie; Dauvin, Jean-claude; Delavenne, Juliette; Dewarumez, Jean-marie; Dupuis, Ludovic; Foveau, Aurélie; Garcia, Clément; Gardel, Laure; Harrop, Stuart; Just, Roger; Koubbi, Philippe; Lauria, Valentina; Martin, Corinne; Meaden, Geoff; Morin, Jocelyne; Ota, Yoshi; Rostiaux, Emilie; Smith, Bob; Spilmont, Nicolas; Vaz, Sandrine; Villanueva, Ching-maria; Verin, Yves; Walton, Joanne; Warembourg, Caroline.
Readers of our first CHARM I atlas will know that almost everything contained within the atlas was original work resulting from two years of intensive study of the Dover Strait by a dedicated and inter- disciplinary team working from bases on either side of the Channel. The present atlas has carried on this eminent precedent, though this time covering the whole of the eastern English Channel (figure 1) and widening considerably the thematic scope. We believe that readers of this current atlas will be impressed by both the breadth and depth of the information provided, and that therefore this content should be available for use in both a wide variety of fields and at various levels of interest (researchers, industries, statutory organisations, the wider...

INTRODUCTION: The Dover Strait (Figure 1) connects the North Sea to the English Channel. Here, northern France and South-East England are at their closest. This narrow corridor, one of the world's busiest straits for maritime shipping, is a key economic area for numerous activities, such as leisure and tourism, international ports and shipping, plus the exploitation of living or abiotic marine resources. This area is a significant resource for fisheries because many commercial fish species are abundant there, but also because of the presence of nursery and spawning areas and migratory routes linked to specific environmental characteristics. The vulnerability of these resources, which are subjected to strong anthropogenic pressures, has brought together...

Growth of an Inshore Antarctic fish, Trematomus newnesi (Nototheniidae), off Adelie Land ArchiMer
Mahe, Kelig; Elleboode, Romain; Loots, Christophe; Koubbi, Philippe.
Dusky rockcod, Trematomus newnesi, is a widely distributed neritic circumpolar Antarctic fish species. We conducted a study on age and growth of Trematomus newnesi in coastal waters of Adélie Land in East Antarctica. A total of 289 specimens were collected in 2003, 2005, 2006 and 2009. They consisted of 122 females, 132 males and 35 immature specimens. Total length (TL) and total weight (W) of these fish ranged from 13.5 to 25 cm and 19.7 to 174 g respectively for females and from 12 to 20.9 cm and from 24.1 to 144.1 g for males. The TL/W relationship was described by the following parameters: a=7.2.10-3 and b=3.127, showing no significant difference between sex (ANCOVA, P<0.05). Fish age was estimated by counting annual growth increments on polished...

Integrated assessment of the spatial distribution and structural dynamics of deep benthic marine communities ArchiMer
Jansen, Jan; Dunstan, Piers K.; Hill, Nicole A.; Koubbi, Philippe; Melbourne‐thomas, Jessica; Causse, Romain; Johnson, Craig R..
Characterising the spatial distribution and variation of species communities and validating these characteristics with data from the field are key elements for an ecosystem‐based approach to management. However, models of species distributions that yield community structure are usually not linked to models of community dynamics, constraining understanding and management of the ecosystem, particularly in data‐poor regions. Here we use a qualitative network model to predict changes in Antarctic benthic community structure between major marine habitats characterised largely by seafloor depth and slope, and use multivariate mixture models of species distributions to validate the community dynamics. Further, we then assess how future increases in primary...

Low-diversity bacterial microbiota in Southern Ocean representatives of lanternfish genera Electrona, Protomyctophum and Gymnoscopelus (family Myctophidae) ArchiMer
Gallet, Alison; Koubbi, Philippe; Léger, Nelly; Scheifler, Mathilde; Ruiz-rodriguez, Magdalena; Suzuki, Marcelino T.; Desdevises, Yves; Duperron, Sebastien.
Myctophids are among the most abundant mesopelagic teleost fishes worldwide. They are dominant in the Southern Ocean, an extreme environment where they are important both as consumers of zooplankton as well as food items for larger predators. Various studies have investigated myctophids diet, but no data is yet available regarding their associated microbiota, despite that the significance of bacterial communities to fish health and adaptation is increasingly acknowledged. In order to document microbiota in key fish groups from the Southern Ocean, the bacterial communities associated with the gut, fin, gills and light organs of members of six species within the three myctophid genera Electrona, Protomyctophum and Gymnoscopelus were characterized using a 16S...

Modelling Fish Habitat Suitability in the Eastern English Channel. Application to community habitat level ArchiMer
Vaz, Sandrine; Carpentier, Andre; Loots, Christophe; Koubbi, Philippe.
Valuable marine habitats and living resources can be found in the Eastern English Channel and in 2003, a Franco-British Interreg IIIA project, ‘Eastern Channel Habitat Atlas for Marine Resource Management’ (CHARM), was initiated to support decision-making for management of essential fish habitats. Fish habitat corresponds to geographic areas within which ranges of environmental factors define the presence of a particular species. Habitat Suitability index (HSI) modelling was used to relate fish geographic distribution and their relation towards environmental factors and to delineate their optimum habitat. This study was based on data obtained from 1988-2003 IFREMER’s Channel Ground Fish Surveys, including both species abundance and environmental data....

Morphological variability of the shape of striped red mullet Mullus surmuletus in relation to stock discrimination between the Bay of Biscay and the eastern English Channel ArchiMer
Mahe, Kelig; Villanueva, Ching-maria; Vaz, Sandrine; Coppin, Franck; Koubbi, Philippe; Carpentier, Andre.
Striped red mullet Mullus surmuletus L. 1758 is an economically important species in the Mediterranean Sea and in the northern Atlantic Ocean, where it is exploited from the Bay of Biscay to the southern North Sea (ICES, 2010). In Atlantic waters, there are two main areas where this species is caught, the Bay of Biscay and the eastern English Channel. This species was initially exploited by the Spanish fleets along the Spanish coast inside the Bay of Biscay. Originally considered as valuable by-catch (Marchal, 2008), the growing exploitation ofM. surmuletus and a conspicuous increase in landings in the English Channel and the southern North Sea by French, English and Dutch fleets have been observed from the 1990s onwards. This was attributed to an increase...

Ontogenetic shift in the energy allocation strategy and physiological condition of larval plaice (Pleuronectes platessa) ArchiMer
Di Pane, Julien; Joly, Lea; Koubbi, Philippe; Giraldo, Carolina; Monchy, Sébastien; Tavernier, Eric; Marchal, Paul; Loots, Christophe.
Condition indices aim to evaluate the physiological status of fish larvae by estimating both the level of starvation and potential of survival. Histological indices reveal direct effects of starvation whereas biochemical indices such as lipid classes or RNA:DNA ratios are used as proxies of condition, giving information on the amount of energy reserves and growth rate, respectively. We combined these three indices to evaluate ontogenetic variations of growth performance, lipid dynamics and nutritional condition of plaice larvae caught in the field during winter 2017 in the eastern English Channel and the Southern Bight of the North Sea. RNA:DNA ratios showed that larvae at the beginning of metamorphosis (stage 4) had a lower growth rate than younger...

Spatial distribution and interannual variations in the size frequency distribution and abundances of Pleuragramma antarcticum larvae in the Dumont d’Urville Sea from 2004 to 2010 ArchiMer
Koubbi, Philippe; O'Brien, Colleen; Loots, Christophe; Giraldo, Carolina; Smith, Martina; Tavernier, Eric; Vacchi, Marino; Vallet, Carole; Chevallier, Jean; Moteki, Masato.
This paper investigates the abundance and distribution of Pleuragramma antarcticum larvae by size class in the Dumont d’Urville Sea from 2004 to 2010. Samples were collected between Dumont d’Urville station and the Mertz Glacier Tongue onboard the RV l’Astrolabe for studying the inter-annual and spatial distribution of fish larvae and the TRV Umitaka Maru for looking at life stages vertical distributions. The seabed depression adjacent to the Mertz Glacier Tongue and in Commonwealth Bay hosted high abundances of small P. antarcticum larvae, while larger larvae were found in lower abundance and further offshore. We found that canyons, sea ice, stability of the water column and temperatures are important features for determining suitable areas for young...

Spatial patterns and GIS habitat modelling of Solea solea, Pleuronectes flesus and Limanda limanda fish larvae in the eastern English Channel during the spring ArchiMer
Koubbi, Philippe; Loots, Christophe; Cotonnec, Gwenaelle; Harlay, Xavier; Grioche, Alain; Vaz, Sandrine; Martin, Canterbury Christ Church University; Walkey, Mike; Carpentier, Andre.
The spring distribution of larval fish stages of flatfishes in the Dover Strait (eastern English Channel) was studied in 1995 and 1999. Fish larvae were identified and sorted according to developmental stages in order to study their ontogenic distribution. The French coastal waters are characterised by an unstable tide-dependent front, which influences larval dispersion. In spring, the French coastal waters have a high phytoplanktonic production. They have higher temperatures, lower salinities and differences in current intensity compared with the central English Channel waters. Generalised Additive Models (GAM) combined with Geographic Information Systems (GIS) were used to model the potential habitats of life stages considering data from three major...

Spawning distribution of North Sea plaice and whiting from 1980 to 2007 ArchiMer
Loots, Christophe; Vaz, Sandrine; Planque, Benjamin; Koubbi, Philippe.
The spatial distributions of spawning population of North Sea plaice and whiting were studied using geostatistical analyses. Variograms were computed each year since 1980 on abundance data of spawning adults using the first quarter data from the International Bottom Trawl Survey. Maps of spatial distribution of spawning adults were produced using kriging interpolation. For both species, distributions of spawning adults were in agreement with historical spawning grounds previously described from location of their eggs. This showed that spawning adults distribution may be used to infer the distribution of both plaice during its spawning peak and whiting at the beginning of its spawning period. Both species were strongly spatially structured with abundances...

Understanding what controls the spawning distribution of North Sea whiting (Merlangius merlangus) using a multi-model approach ArchiMer
Loots, Christophe; Vaz, Sandrine; Planque, Benjamin; Koubbi, Philippe.
The processes that control the spatial distribution of North Sea whiting (Merlangius merlangus) spawning adults are investigated using a statistical multi-model approach. Models of external and internal controls on the population, such as environmental conditions, spatial constraints, present or past spatial distribution, and demographic state of the population, are evaluated, compared and ranked to select those that are the best able to predict the observed distribution of spawning adults. Model selection is greatly influenced by the selection method, either based on data fitting or prediction, as well as by the threshold value used to stop the selection. Model selection based on prediction tends to select simpler models than selection based on data...

What controls the spatial distribution of the North Sea plaice spawning population? Confronting ecological hypotheses through a model selection framework ArchiMer
Loots, Christophe; Vaz, Sandrine; Planque, Benjamin; Koubbi, Philippe.
The spatial dynamics of spawning fish are crucial because they influence the survival rates of eggs and larvae and ultimately impact the reproductive success of populations. The factors that control these dynamics are complex and potentially many, and they interact. A model-selection-based approach was developed to confront various hypotheses of control of the spatial distribution of spawning population of North Sea plaice (Pleuronectes platessa). For each hypothesis or combination thereof, statistical models were constructed. These were then ranked and selected based on their ability to adjust and predict observed spatial distributions. The North Sea plaice population seems to have developed strong attachment to specific spawning sites, where geographic...
