“…However, 0-group sole are smaller in this area and this growth deficit is not compensated for in the following year, indicating durable effects of habitat constraints on fish size (Le Pape et al 2003a). The field data presented here confirmed growth deficit and showed that wild 0-group sole did not meet their temperature-dependent physiological potential for growth.…”

“…In addition to abiotic-dependent effects in an embayed area, the Pertuis Charentais are characterised by reduced river inputs, young sole densities among the highest for the Bay of Biscay nurseries (Le Pape et al 2003a) and intensively farmed areas. Reduced influence of river discharge has been shown to reduce young-of-the-year abundance (e.g.…”

“…In the Bay of Biscay, the main nursery grounds have been localised in estuaries and bays from yearly autumn surveys (Le Pape et al 2003a). Comparison of various biological indicators indicated quality differences between nurseries, depending on the particular estuary or bay location (Le Pape et al 2003b;Gilliers et al 2006).…”

-Tidal embayments in the Bay of Biscay (France) host nursery grounds where common sole, Solea solea, is the most abundant flatfish species. This study aimed to appraise the way those habitats function as nurseries through juvenile sole's responses in somatic growth and condition (Fulton's K) during their first year of occupancy. Field data, two yearly trawling series, taken monthly, were compared with a 6-month-long mesocosm experiment involving reared fish of the same wild origin. Growth rates were compared with predicted maximum growth according to an experimentally established model in relation to temperature. In the field, 0-group sole total length (TL) averaged 130 mm from September onwards in 1999 and 2000. Mean growth rates were 0.7-0.9 mm day −1 in summer and 0.1 mm day −1 in autumn, when the model predicted 1.4 and 0.9 mm day −1 , respectively. In the mesocosm, the growth rates were 0.9 and 0.4 mm day −1 for the same seasons and for stocking densities (300 fish 1000 m −2 ) about 10 times higher than usually recorded in the field. Wild sole remained in medium condition (K ca. 1 g cm −3 ) during the entire growing season, whereas they attained a higher K after being released into the mesocosm (1.2-1.3 g cm −3 ). During the mesocosm experiment, growth was shown to be primarily temperature-controlled: fish reached 150-160 mm (TL) in November. From this investigation, it can be concluded that sole's responses in condition and growth are altered over the whole growing season on nursery grounds. The situation is exacerbated in autumn when the sum of abiotic constraints increases as the competitive biomass does. This indicates impairment of the nursery functioning which, in the context of fish habitat conservation, emphasises the particular vulnerability of embayments to the addition of any further constraint.

Les baies du golfe de Gascogne (France) hébergent des habitats où la sole, Solea solea, est le plus abondant des poissons plats. Cette étude vise à évaluer le fonctionnement des habitats pour leur rôle de nourriceries, en analysant la croissance et la condition des juvéniles de sole pendant leur première année. Les données de deux séries, 1999 et 2000, de chalutages mensuels sont comparées à celles acquises lors d'une expérience de 6 mois en mésocosme impliquant l'élevage de poissons originaires de la même nourricerie. La croissance observée est comparée à la croissance potentielle, en utilisant un modèle expérimental décrivant la croissance en fonction de la température. Les soles du groupe d'âge 0 capturées dans la nourricerie atteignent une taille moyenne de 130 mm en septembre. Le taux de croissance est de 0,7-0,9 mm jour −1 en été et 0,1 mm jour −1 en automne, alors que le modèle prédit respectivement 1,4 et 0,9 mm jour −1 . En mésocosme, la cro...

“…In this region, the 3 nursery sectors where the slipper limpet is present are also sectors where estuarine influence is absent or very limited (Le Pape et al 2003c). Thus, we did not include estuarine influence and our description of YOY sole density was based on coastal sector, bathymetry and sediment texture.…”

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. These linear models were used to quantify the effect of the presence and density of the slipper limpet on the density of young-of-the-year sole in nursery habitats. Despite large variability in the data set, this quantitative approach emphasised the negative role of the mollusc on juvenile sole density in the Bay of Biscay. There was no apparent effect of the slipper limpet on the extent of the sole nursery grounds, but the density of young-of-the-year sole was significantly lower where this invasive species was established. The negative effect of this invasive species on nursery habitat capacity and sole stock recruitment is discussed.

The Lesina lagoon is located on the southern Adriatic coast of Italy; many marine species, such as the shrimp M. kerathurus, use the Lesina lagoon as a nursery, spending their initial growth phase there. In order to assess the usefulness of migratory species as biomonitors of the environmental quality of this nursery area, we evaluated the metal content of the M. kerathurus juveniles at the end of their growth phase in the lagoon (October), when they are assumed to have bioaccumulated the maximum level of metals from the lagoon environment. The concentrations of Cr, Cd, Pb, Zn, Mn and Cu were measured in the muscle and exoskeleton of the shrimp, and in the sediments and waters of three areas of the Lesina Lagoon. Both the water and sediment levels of the investigated metals tended to fall within the ranges recorded for other lagoon environments characterized by similar anthropic impact and texturally similar sediment; the juveniles of the shrimp M. kerathurus proved to be strong bioaccumulators of heavy metals such as Zn and Cu (biota-sediment accumulation factors -BSAFs -6.01 and 25.0 respectively), which derive from agricultural activities; therefore, at the end of their growing phase in the lagoon they can be considered useful biomonitors of metal contamination of agricultural origin in their nursery area.
