A hierarchical Bayesian model for embedding larval drift and habitat models in integrated life cycles for exploited fish ArchiMer
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...

Adult-mediated connectivity affects inferences on population dynamics and stock assessment of nursery-dependent fish populations ArchiMer
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...

Age estimation in common sole Solea solea larvae: validation of daily increments and evaluation of a pattern recognition technique ArchiMer
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...

Analyse des campagnes SOLPER - 2005 à 2012 ArchiMer
Leaute, Jean-pierre; Aubert, Fabien; Lepareur, Fanny; Coupeau, Yann; Boiron-leroy, Anne.
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 (<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...

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) ArchiMer
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...

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...

Détermination de la condition des juvéniles de sole (Solea solea) dans les pertuis Charentais (suivi saisonnier d'avril à juillet) ArchiMer
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...

Effect of an invasive mollusc, American slipper limpet Crepidula fornicata, on habitat suitability for juvenile common sole Solea solea in the Bay of Biscay ArchiMer
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....

Effect of exposure to petroleum hydrocarbons upon cardio-respiratory function in the common sole (Solea solea) ArchiMer
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...

Effect of nursery habitat degradation on flatfish population: Application to Solea solea in the Eastern Channel (Western Europe) ArchiMer
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...

Effects of exposure to petroleum hydrocarbons upon the metabolism of the common sole Solea solea ArchiMer
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...

Effects of water viscosity upon ventilation and metabolism of a flatfish, the common sole Solea solea (L.) ArchiMer
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...

Etude de la composition corporelle de la sole (Solea solea ) au cours du jeune: Influence de la temperature ArchiMer
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.

Étude des voies de bioactivation du benzo[a]pyrène et du fluoranthène chez la sole commune (Solea solea) : Profil métabolique et génotoxicité ArchiMer
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,...

Etude preliminaire des equilibres de distribution de l'eau et des ions au cours de l'ovogenese de Solea solea ArchiMer
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.

Habitat suitability for juvenile common sole (Solea solea, L.) in the Bay of Biscay (France): A quantitative description using indicators based on epibenthic fauna ArchiMer
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...

Impact of climatic and anthropogenic changes on living resources in the Bay of Biscaye ArchiMer
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 & 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...

Investigating spatial heterogeneity of von Bertalanffy growth parameters to inform the stock structuration of common sole, Solea solea, in the Eastern English Channel ArchiMer
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...

Metamorphosis and estuarine colonisation in the common sole, Solea solea (L.): implications for recruitment regulation ArchiMer
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...
