We investigated the quantitative genetics of plasticity in resource allocation between survival, growth and reproductive effort Crassostrea gigas when food abundance varies spatially. Resource shifted from survival to as increased. An optimality model suggests that this plastic shift may be adaptive. Reproductive mean were highly heritable, whereas for growth, both had low heritability. The genetic correlations negative poor treatments, suggesting trade-offs, but positive rich ones. These...
The proliferation of the voluntarily-introduced cupped oyster, Crassostrea gigas, has attained proportions species invasion in many intertidal habitats Europe, presumably resulting from successful reproduction farmed individuals. It is thus imperative to better understand reproductive characteristics oysters, since they are directly under human control. We quantified dry tissue mass (DTM), gametosomatic index (GSI), and cycle oysters at two sites Bourgneuf Bay, France, relation environmental...

This study investigated the effects on physiology of Pacific oyster, Crassostrea gigas, a mixture pesticides containing 0.8 μg L(-1) alachlor, 0.6 metolachlor, 0.7 atrazine, terbuthylazine, 0.5 diuron, fosetyl aluminum, 0.05 carbaryl, and glyphosate for total concentration 4.55 . The nominal corresponds to pesticide concentrations in shellfish culture area Marennes-Oleron basin. Two varieties C. gigas were selected foreshore, based their characteristics terms resistance summer mortality,...

Variations in gill, palp, and adductor muscle areas the length spacing of eulatero-frontal cirri (EFC) were investigated specimens Japanese oyster (Crassostrea gigas) within same bay two nearby sites (15 km) differing turbidity. Significant variations occurred on a small geographical scale. In particular, individuals from higher turbidity zone had smaller gills larger labial palps. For standard (1 g dry body weight), gill area was 25% oysters low-turbidity zone, while palp 66% high-turbidity...
Summary Due to the important economic activity of oyster production in France, microalgal toxic events represent a significant constraint for shellfish farmers who face closures bivalve production‐sites. The frequency 3 weeks or less represents half total along French coasts. Cold storage could be simple and affordable solution temporary short‐term before commercialisation. A stock marketable Pacific Crassostrea gigas was therefore stored during 22 days non‐immersed conditions at °C with...
The objective of this study was to identify a possible effect food on the acceleration decontamination in blue mussels, Mytilus edulis, containing diarrhetic toxins belonging okadaic acid (OA) structural group. An experimental protocol designed describe and compare kinetics detoxification rates naturally OA-contaminated mussels that had either received or not for three weeks. applied two trials (in June 2006 2007, called Ker06 Ker07), conducted one year apart samples collected same area, at...
Spatial and temporal variations in gill palp size were studied during 1 year naturally-settled populations of the Pacific oyster Crassostrea gigas, reciprocally transplanted between two contrasting sites located along a marked gradient turbidity conditions. The variability suspended particulate matter (SPM) food particles, estimated by concentration chlorophyll-a, was measured with situ water-quality probes. Over full seasonal cycle, oysters exposed to high-turbidity (HT) conditions...
Oyster farming in France is a traditional activity. Each year, 149 000 tons of oysters are fattened before being sold. More and more oyster farmers supplement the diet by microalgae to optimize fattening process improve both growth flesh quality oysters. In present study, were supplemented two microalgae: Skeletonema costatum Tahitian isochrysis clone. The ash, protein, carbohydrate (including glycogen), lipid contents analyzed. was improved when they with microalgae, leading an increase...
Oyster farming is of real economic interest in France. farmers attach more and importance to improving the growth quality their oysters. Some fatty acids known be aroma precursors originate from microalgae such as Skeletonema costatum Tahitian isochrysis clone. These were used fatten oysters order observe role development oysters' aroma. This study shows that profile influenced by contribution two (as reported first paper this series: Pennarun, A.-L.; Prost, C.; Haure, J.; Demaimay, M....
