Relationships between benthic macrofauna and habitat suitability for juvenile common sole (Solea solea, L.) in the Vilaine estuary (Bay of Biscay, France) nursery ground
Provedor de dados: 5
Autores: Nicolas, Delphine; Le Loch, Francois; Desaunay, Yves; Hamon, Dominique; Blanchet, Aline; Le Pape, Olivier.
Coastal and estuarine systems are among the most threatened by human activities which damage their ecological function and, in particular, their nursery role for many marine species. In this context, the protection of these vital ecosystems is a critical issue for the management of fisheries resources. To that aim, functional approaches have to be developed that make it possible to assess habitat suitability and quality. The common sole, Solea solea (L.) was selected as an indicator species to identify the features of coastal and estuarine nursery habitats in the Bay of Biscay (France).   Previous studies have shown that young-of-the-year (YOY) sole are strongly dependent upon various abiotic factors, and especially bathymetry, sediment cover and the...

Investigating spatial heterogeneity of von Bertalanffy growth parameters to inform the stock structuration of common sole, Solea solea, in the Eastern English Channel
Provedor de dados: 5
Autores: Du Pontavice, Hubert; Randon, Marine; Lehuta, Sigrid; Vermard, Youen; Savina-rolland, Marie.
In fisheries science, a mismatch between the delineation of a fish stock and the underlying biological population can lead to inaccurate assessment and management. Previous results suggested a potential spatial structuration of the Eastern English Channel (EEC) stock of common sole, Solea solea, in three sub-populations. In this article, we propose to investigate the spatial population structure of common sole in the EEC using the von Bertalanffy Growth Function parameters as indicators of population segregation. In order to test the sub-population hypothesis and evaluate its robustness to data sources, we developed three models, all including an area effect on growth parameters. The first model was aimed at testing a potential data source effect (in...

Effects of exposure to petroleum hydrocarbons upon the metabolism of the common sole Solea solea
Provedor de dados: 5
Autores: Davoodi, Fariba; Claireaux, Guy.
On December 12th, 1999, the oil tanker Erika sank off the southern coast of Brittany (France), releasing 20 000–30 000 tons of heavy oil in the open sea. Among the affected coastal habitats were important nurseries for numerous flatfish species and particularly for the common sole, Solea solea. To investigate the potential impact of the spill on this economically significant resource, we employed Fry's concept of metabolic scope for activity to assess the deleterious effect of fuel exposure on the functional integrity of juvenile sole. Fish were captured from uncontaminated areas and experimentally exposed to contamination conditions mimicking those encountered during the weeks that followed the Erika spill. Using respirometry techniques we measured basal...

Metamorphosis and estuarine colonisation in the common sole, Solea solea (L.): implications for recruitment regulation
Provedor de dados: 5
Autores: Amara, Rachid; Lagardere, Francoise; Desaunay, Yves; Marchand, Jocelyne.
Processes involved in both metamorphosis and settlement of young sole were studied at the population, cohort and individual level in order to evaluate their role in survival and recruitment regulation. Metamorphosis can be defined as a phase of variable duration (10 days on average) at the end of which the larval period of pelagic dissemination is completed. Size at the onset of metamorphosis is considerably less variable than age and is less plastic to environmental change. Metamorphosis is triggered by the acquisition of a competent size and a sufficient store of energy supplies, and occurs without a nutritional crisis or growth arrest. In addition, changes in organogenesis and behaviour that occur during metamorphosis seem to contribute to horizontal...

Impact of climatic and anthropogenic changes on living resources in the Bay of Biscaye
Provedor de dados: 5
Autores: Goulletquer, Philippe.
Fisheries and aquaculture are of major importance to the coastal communities throughout the Bay of Biscaye. Almost half of French fishermen rely on catches from the Bay which achieve and estimated first sale value of more than €525m annually. Moreover, emblematic species such as eels have an additional economic as weil as social value for coastal communities. Similarly, the main French shellfish rearing areas are located within the Bay of Biscaye. They contribute predominantly to the yearly spat (mussel &amp; oyster) recruitment, used to sustain the entire French shellfish industry. These activities have a direct impact on ecosystem functioning and biodiversity. Meanwhile, drastic environmental changes have been reported over the last 30 years, including a...

Phenotypic and genetic differentiation in young-of-the-year common sole (Solea solea) at differentially contaminated nursery grounds
Provedor de dados: 5
Autores: Guinand, Bruno; Durieux, Eric D. H.; Dupuy, Celie; Cerqueira, Frederique; Begout, Marie-laure.
Growth-related characters, condition factor, and genetic differentiation were investigated for a single cohort of young-of-the-year (YOY) sole within and among nurseries with differing levels of heavy metals (Cd, Cu and Zn) contamination in the two Charentais Straits, Bay of Biscay, France. Analyses were performed when individuals recruited (May), then after a full summer spent in each nursery (October). Levels of phenotypic and genetic diversity were compared, together with genetic differentiation at a candidate metallothionein (MT) locus and three putatively neutral microsatellite loci. No phenotypic or genetic differentiation was detected among nurseries in May, but significant variation at each phenotypic trait and at the multilocus level in October (P...

Evaluating the histological-based condition of wild collected larval fish: A synthetic approach applied to common sole (Solea solea)
Provedor de dados: 5
Autores: Di Pane, Julien; Gendrot, F.; Giraldo, Carolina; Marchal, Paul; Koubbi, Philippe; Loots, Christophe.
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...

Effect of an invasive mollusc, American slipper limpet Crepidula fornicata, on habitat suitability for juvenile common sole Solea solea in the Bay of Biscay
Provedor de dados: 5
Autores: Le Pape, Olivier; Guerault, Daniel; Desaunay, Yves.
This study describes the effect of an invasive mollusc, the slipper limpet Crepidula fornicata, on the distribution and abundance of young-of-the-year sole Solea solea in coastal nursery areas, based on beam-trawl surveys in the Bay of Biscay (France) over a 3 yr period (2000 to 2002). As habitat suitability for juvenile sole varies according to bathymetry and sediment structure, these factors and the density of the slipper limpet were used as descriptors in generalised linear models of habitat suitability to characterise the distribution of juvenile sole. The models were based on a delta distribution, coupling a binomial model testing for the presence of juvenile sole with a log-normal distribution for density when juveniles were known to be present....

Age estimation in common sole Solea solea larvae: validation of daily increments and evaluation of a pattern recognition technique
Provedor de dados: 5
Autores: Lagardere, Françoise; Troadec, Herve.
Close similarities have been found between the otoliths of sea-caught and laboratory-reared larvae of the common sole Solea solea (L.), given appropriate temperatures and nourishment of the latter. But from hatching to mouth formation. and during metamorphosis, sole otoliths have proven difficult to read because the increments may be less regular and low contrast. In this study, the growth increments in otoliths of larvae reared at 12 degrees C were counted by light microscopy to test the hypothesis of daily deposition, with some results verified using scanning electron microscopy (SEM), and by image analysis in order to compare the reliability of the 2 methods in age estimation. Age was first estimated (in days posthatch) from light micrographs of whole...

Coupling hydrodynamic and individual-based models to simulate long-term larval supply to coastal nursery areas
Provedor de dados: 5
Autores: 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...

Extensive larval dispersal and restricted movement of juveniles on the nursery grounds of sole in the Southern North Sea
Provedor de dados: 5
Autores: Delerue-ricard, Sophie; Darnaude, Audrey M.; Raeymaekers, Joost A.m.; Dundas, Siv Hjorth; Skadal, Julie; Volckaert, Filip A.m.; Geffen, Audrey J.
Connectivity between spawning and nursery grounds influences the colonization, replenishment and resilience of populations of marine organisms. Connectivity rate, measured as the exchange of individuals between spawning and nursery grounds, is therefore a crucial determinant of stock size. However, connectivity of early-life stages is hard to explore due to sampling limitations and insufficient knowledge on potential larval sources. Here we present new insights into pre- and post-settlement dispersal of the common sole (Solea solea L.) at a spatial scale of 5–500 km in the Southern North Sea. Patterns at a scale of &lt;100 km were considered local, whereas patterns further than 100 km were considered regional. Multi-elemental signatures of the otolith edge...

Spatial analysis of the trophic interactions between two juvenile fish species and their preys along a coastal-estuarine gradient
Provedor de dados: 5
Autores: Kopp, Dorothee; Le Bris, Herve; Grimaud, Lucille; Nerot, Caroline; Brind'Amour, Anik.
Coastal and estuarine systems provide nursery grounds for many marine fish species. Their productivity has been correlated with terrigeneous inputs entering the coastal-estuarine benthic food web, thereby favouring the establishment of fish juveniles. Studies in these ecosystems often describe the nursery as a single large habitat without verifying nor considering the presence of contiguous habitats. Our study aimed at identifying different habitats based on macrozoobenthic communities and morpho-sedimentary characteristics and assessing the trophic interactions between fish juveniles and their benthic preys within these habitats. It included 43 sampling sites covering 5 habitats in which we described taxonomically and quantitatively the invertebrates and...

Etude preliminaire des equilibres de distribution de l'eau et des ions au cours de l'ovogenese de Solea solea
Provedor de dados: 5
Autores: Gallis, J; Lemenn, F; Lebrun, A; Nunez, R.
During oogenesis of Solea solea L., gonadal changes in water, Na super(+) and K super(+) ions seem to be related to yolk protein incorporation by the oocyte. The decrease in oocyte water accumulation, associated with an increase in pericellular water accumluation and a decrease in K super(+) concentration occurs when vitellogenin enters the oocyte. Na super(+) concentration decreases in the oocyte at the end of the exogenous vitellogenesis when the first stages of the oocyte maturation take place. Water accumulation in the pericellular space during vitellogenesis allows the rapid transfer of water from this compartment into the oocyte during the terminal phase of maturation. However the total amount of gonadal water remains stable.

Conséquences à long terme d'une exposition précose à l'hypoxie sur la physiologie du bar européen (Dicentrarchus labrax) et de la sole commune (Solea solea)
Provedor de dados: 5
Autores: Vanderplancke, Gwenaelle.
The dissolved oxygen in seawater has steadily declined in many coastal marine ecosystems in the last 50 years because of global warming and increasing coastal human activities. This decrease in oxygen in seawater causes episodes of hypoxia increasingly frequent and severe in coastal and estuarine areas. Some organisms may escape these environmental constraints by migration or dispersion. Others, with limited swimming capabilities must implement physiological regulation (phenotypic plasticity) to enable them to adapt and survive. This is particularly the case of marine fish larvae that are likely to be present in coastal nursery at the end of their development. It is now well established that the regulations implemented by organisms to cope with their...

Etude de la composition corporelle de la sole (Solea solea ) au cours du jeune: Influence de la temperature
Provedor de dados: 5
Autores: Richard, P; Djabali, M; Lagardere, Francoise; Lagardere, J.
The effects of starvation on Solea solea at 10 and 20 degree C in sea water, were studied. At 20 degree C fishes start to die on week 4; at 10 degree C they support a longer starvation period (9 weeks). Proximate analysis shows that protein are more steadily used at 20 degree C than at 10 degree C, contrarily to the corporal lipids which are used at the same rate. Starvation results in a reduction of liver lipids and glycogen. This reduction is more pronounced at 20 degree C : 70% of hepatic glycogen is used at this temperature within the first week of starvation against 30% at 10 degree C.

A hierarchical Bayesian model for embedding larval drift and habitat models in integrated life cycles for exploited fish
Provedor de dados: 5
Autores: Rochette, Sebastien; Le Pape, Olivier; Vigneau, Joel; Rivot, Etienne.
This paper proposes a hierarchical Bayesian framework for modeling the life cycle of marine exploited fish with a spatial perspective. The application was developed for a nursery-dependent fish species, the common sole (Solea solea), on the Eastern Channel population (Western Europe). The approach combined processes of different natures and various sources of observations within an integrated framework for life-cycle modeling: (1) outputs of an individual-based model for larval drift and survival that provided yearly estimates of the dispersion and mortality of eggs and larvae, from spawning grounds to settlement in several coastal nurseries; (2) a habitat suitability model, based on juvenile trawl surveys coupled with a geographic information system, to...

Autores: Archarnbault, Benoit; Le Pape, Olivier; Baulier, Loic; Vermard, Youen; Veron, Matthieu; Rivot, Etienne.
We explore how alternative hypotheses on the degree of mixing among local subpopulations affect statistical inferences on the dynamics and stock assessment of a harvested flatfish population, namely, the common sole population in the Eastern Channel (ICES area VIId). The current paradigm considers a single, well-mixed, spatially homogeneous population with juveniles from all coastal nursery grounds along the French and UK coasts that contribute to a single adult population and one pool of eggs. Based on the available data and ecological knowledge, we developed a spatial Bayesian integrated life-cycle model that consists of three subpopulations (one near the UK coast and two near the French coast, denoted UK, West FR and East FR, respectively) supported by...

Autores: 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...

Autores: Rochette, S.; Rivot, Etienne; Morin, Jocelyne; Mackinson, S.; Riou, Philippe; Le Pape, Olivier.
Estuaries and coastal waters are essential nursery habitats for many marine species, and especially for flatfishes. Thus, investigating how anthropogenic disturbances affect the quality of these habitats is of major importance to understand their consequences on the population renewal of marine species. The aim of the present study was to analyse the effects of estuarine habitat degradation on the population of the common sole in the Eastern Channel, a key species in the fish community and fisheries in this area. We especially focused on the drastic drop in the surface area and on the low water quality of the Seine estuary, the main river of the Eastern Channel. A geographic Information System (GIS) was used to develop quantitative maps of sole nursery...

A large number of studies on common sole have already been done for years by many research laboratories. This study sought to make a focus on a major nursery on the Atlantic coast, the Pertuis charentais, through the results of eight annual surveys (2005-2012) in late summer (SOLe PERtuis) targeting sole juveniles with a small beam trawl until subtidal zone (&lt;1.50 m). Some of the results obtained in this report confirm previous studies, such as, among others, that more than 80% YOY (G0) occupy muddy or sandy mud bottom at a depth less than 5 m, or that there is a relative correlation between large rainfall in the spring, river flows and abundance of G0 in nursery.   However in the Pertuis Breton this correlation is little expressed by an extension of...

Habitat suitability for juvenile common sole (Solea solea, L.) in the Bay of Biscay (France): A quantitative description using indicators based on epibenthic fauna
Provedor de dados: 5
Autores: Le Pape, Olivier; Baulier, Loic; Cloarec, Aurélie; Martin, Jocelyne; Le Loch, Francois; Desaunay, Yves.
This study describes the spatial distribution of young-of-the-year common sole based on beam trawl surveys conducted in late summer in the coastal and estuarine parts of the Bay of Biscay (France). Previous studies showed that habitat suitability for juvenile common sole varies according to physical factors and notably bathymetry and sediment structure. Nevertheless, the use of these descriptors alone to model habitat suitability led to considerable unexplained variability in juvenile common sole distribution. Hence, the epibenthic macro- and megafauna collected during beam trawl surveys was taken into account to improve models of habitat suitability for these juvenile flatfish. Ecotrophic guilds based on life traits (behaviour, mobility and feeding) were...

Overlapping external morphometric characters easily confound the flatfishes Solea aegyptiaca and Solea solea (Soleidae) in areas of the Mediterranean Sea where both species live in sympatry. This leads to uncertainties in the fisheries and marketing of the species, in addition to misinterpretations in biogeography and conservation studies. Here we describe a simple restriction fragment length-based diagnostic test, which differentiates S. solea from S. aegyptiaca, as well as from other species of the Soleidae family. Furthermore, we show that the two species living in sympatry in the Gulf of Kavala (North Aegean Sea, Greece) present significant qualitative differences in muscle fatty acid composition, a property which can also be used to distinguish the...

Effect of exposure to petroleum hydrocarbons upon cardio-respiratory function in the common sole (Solea solea)
Provedor de dados: 5
Autores: Claireaux, Guy; Davoodi, Fariba.
The long term consequences of oil exposure upon marine populations are still poorly evaluated. One particular missing piece of information relates to the link between oil exposure, individuals' ability to face environmental contingencies and populations' production and dynamics. In that context, the present paper investigates the impact of oil exposure upon fish cardio-respiratory performance, this performance being viewed as a key determinant of individual fitness. Experimental conditions replicated the contamination conditions observed during the weeks that immediately followed the Erika oil spill (west coast of France; December 1999). Sole (Solea solea), were exposed to number-2 oil for 5 days and were then challenged with an acute rise in temperature...

Effects of water viscosity upon ventilation and metabolism of a flatfish, the common sole Solea solea (L.)
Provedor de dados: 5
Autores: Couturier, Christine; Rouault, Alice; Mckenzie, David; Galois, Robert; Robert, Serge; Joassard, Lucette; Claireaux, Guy.
The French Atlantic coast contains large highly productive intertidal mudflats that are colonised by juveniles of numerous flatfish species, including the common sole (Solea solea, L.). These ecosystems are also heavily exploited by the shellfish farming industry. Intensive bivalve culture is associated with substantial biodeposition (1-6 t-dw ha(-1) day(-1)), which directly or indirectly contributes to increase exopolysaccharide (EPS) concentrations at the interface between water column and seabed. EPS are long-chain molecules organised into colloids, which influence rheological properties of water, particularly viscosity. Increased water viscosity had consequences for ventilatory activity of juvenile flatfish, whereby the minimal pressure required to...

Détermination de la condition des juvéniles de sole (Solea solea) dans les pertuis Charentais (suivi saisonnier d'avril à juillet)
Provedor de dados: 5
Autores: Pinaudeau, Graziella.
Les zones côtières et estuariennes des pertuis Charenta is abritent des nourriceries indispensables à l'accomplissement du cycle biologique de la sole commune (Solea solea). Une récente étude a mis en évidence un parasitisme élevé chez les juvéniles pouvant être lié aux activités conchylicoles soutenues dans cette zone. La cond ition au sens large (croisance en taille et masse, statut lipidique et immunitaire) des juvéniles de sole (GO) est étudiée et un suivi saisonnier de mai à juillet est effectué dans le pertuis Breton. L' indice de condition des juvéniles à leur arrivée sur la nourricerie est de 1,1 g cm-3 ce qui traduit une bonne condition. La croissance plus é levée en mai (0,8 mm j-1) semble ralentir en juillet (0,3 mm j-1). Les réserves lipidiques...

Sole larval supply to coastal nurseries: Interannual variability and connectivity at interregional and interpopulation scales
Provedor de dados: 5

Simulating fish larval drift helps assess 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 meta-population scale (4 assessed stocks), from the southern North Sea to the Bay of Biscay (Western Europe) on a 26-yr time series, from 1982 to 2007. The IBM allowed each particle released to be transported by currents, to grow depending on temperature, to migrate vertically depending on development stage, to die along pelagic stages or to settle successfully on a nursery, representing the life history from spawning to metamorphosis. The model outputs were analysed to...

Autores: Eichinger, Marie; Loizeau, Veronique; Roupsard, Francois; Le Guellec, Anne-marie; Bacher, Cedric.
Experiments were performed on juvenile sole in controlled conditions in the aim of understanding how the biology of common sole may affect the accumulation and dilution of Polychlorinated biphenyls (PCBs). The fish were raised in optimal conditions and divided into two tanks: one control tank and one PCB tank. 4 PCB congeners were added to food for 3 months in the PCB tank; the soles were subsequently fed unspiked food for 3 months. Growth (length and weight) and PCB concentrations were monitored in both tanks and juvenile sole growth was not significantly affected by PCBs in our experimental conditions. We used the Dynamic Energy Budget (DEB) theory to model sole biology and paid special attention to model calibration through the wide use of data from the...

Rapport de la campagne SOLPER 2 (28 août – 2 septembre 2006)
Provedor de dados: 5
Autores: Leaute, Jean-pierre.
To estimate the size, age and abundance distribution of juvenile sole (Solea solea) of nurseries in the Pertuis charentais (France) in 2006, a small beam trawl of 2 m wide and 8 mm stretched mesh was used over a hundred sampling points. The other fish catches have also been recorded and water temperatures measured.

Étude des voies de bioactivation du benzo[a]pyrène et du fluoranthène chez la sole commune (Solea solea) : Profil métabolique et génotoxicité
Provedor de dados: 5
Autores: Wessel, Nathalie.
The aim of this Ph‟D was to study the biotransformation and the genotoxicity of two PAH of interest, namely the benzo[a]pyrene (BaP) and the fluoranthene (Fluo), in the common sole Solea solea, which is a benthic species sensitive to chemical pollution. The use of in vitro exposure models and the application of two different chemical analytical techniques allowed demonstrating that, as in higher vertebrates, the dihydrodiols and the phenols of BaP and Fluo are the major metabolites produced by sole liver enzymes. In vitro, the genotoxic potential of BaP and Fluo was demonstrated in sole, by the production of DNA adducts and oxidative DNA damage. The genotoxicity of Fluo appeared to be 50 fold less important than the genotoxicity of BaP. In the case of BaP,...
