“…In the Bay of Biscay, expected contribution of juvenile common sole, Solea solea, from estuarine waters ranged between 24% and 87% over 15 years. During this period a mean of 48% of all juveniles were found in estuarine, as opposed to fully marine, waters (Le Pape et al, 2003a). Although our study focused on a flatfish in southern California (a dramatically different coastal system), the common sole and stone flounder results are comparable to ours, in which an average of 63% of 0-group halibut resided in embayments and between-year variability was 10%.…”

Coastal ecosystems have been identified as important nursery habitats for many of the world's fishery species. Beyond this, there remain many questions about what exactly constitutes high-value, even critical, habitat for juvenile fish. A first step in investigating nursery habitat value should be to catalogue the spatial coverage (availability) of all potential nursery habitats as well as the distribution (usage) of juvenile fish within those habitats. We conducted two years of fall surveys in the nearshore areas of San Diego County, CA, examining the spatial distribution of 0-group California halibut, Paralichthys californicus. The database generated by 527 otter trawls and block-net seine collections was used to produce a series of models employing regression trees to study the abiotic factors (water column and bottom features) that affect juvenile distributions. Along the exposed coast, highest 0-group densities (0. ). The spatial coverage of potential nursery habitats was calculated using a Geographic Information System (GIS) database, and the total number of resident 0-group halibut within each site was estimated (habitat area Â juvenile halibut density) as a proxy for expected contribution of halibut advancing to the adult stock from each nursery. Although 85% of the potential nursery habitat area occurred along the exposed coastline, 69% (2003) to 58% (2004) of 0-group halibut resided in protected embayments. Embayment contribution is much greater in the southern half of the study region, largely due to Mission and San Diego bays. We conclude that all nursery habitat types demonstrate the potential to contribute significantly to stock fitness, and that in general, shallow and better-protected habitats are highly utilized nurseries for 0-group halibut and deserve special attention in management or conservation efforts.

“…Although the variation in the recruitment rate of the Bay of Biscay sole stock is slight compared with that of other sole stocks and stocks of other species (Le Pape et al 2003b), the variability caused by the slipper limpet invasion was half that caused by interannual variations of sole recruitment over the 3 yr study period. Hence, this relationship, established under standardised conditions of geography and habitat structure, emphasised the negative impact of slipper limpets on habitat suitability for juvenile sole.…”

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.

“…In fact, previous works have pointed to an increase in fishery production following higher river runoff (e.g. Darnaude et al 2004;Le Pape et al 2003;. Various mechanisms underlying the relationship between river runoff and fisheries have been proposed, but food availability has most often been considered the main factor, both through increased planktonic production following nutrient loads (Cloern 2001;Moutin et al 1998) and enrichment in POM in macrobenthic communities .…”

“…According to these studies, higher landings would be expected in years following higher river drainage, with each species' response depending on a time lag reflecting age at recruitment (Darnaude 2005). In the Bay of Biscay, the availability of estuarine nursery grounds, and consequently the production of juvenile S. solea, has been shown to be influenced by the extent of the riverine plume front (Le Pape et al 2003).…”

“…Darnaude et al 2004;Le Pape et al 2003;, the aim of the present study was to analyse the influence of river drainage on landings of Portuguese fisheries, as well as the relative importance of other environmental variables. This study is of particular important in the context of climate change, given the predicted decrease in rainfall in Portugal (Miranda et al 2002).…”

-The Portuguese coast is particularly adequate for studies on the impact of climate change on fisheries, as it has faced an increase in both air and sea surface temperature and a decrease in intensity and frequency of rainfall. Ecological responses to climate change have already been observed in Portuguese waters, with consequences in fisheries. Regional climate models have predicted a further decrease in rainfall in Portugal by the end of the century, which will have a strong impact on the runoff into coastal areas. River drainage affects the physical, chemical and biological properties of coastal ecosystems, regulating habitat availability and favouring their productivity. The present study analysed the influence of river drainage on landings of coastal ports in the vicinity of four hydrologically distinct estuaries. Unlike previous results obtained for the Mediterranean, no significant relationships between river drainage and landings were found. Relationships between drainage and landings can be inconsistent among regions and dependent on how strongly a food web relies on nutrients and organic matter of river origin. In the Portuguese coast, an upwelling regime is of particular importance for the richness and diversity of the coastal ecosystem and for fisheries. The complexity of the coastal upwelling phenomenon together with a possible interaction of several other smaller scale factors acting on recruitment of commercial species may mask the effects of river drainage on landings. Nevertheless, as accentuated decreases in rainfall have been predicted for Portugal, the resulting reduction in river drainage may still strongly impact fisheries in the future.
