| The molecular basis underlying the mechanisms at the origin of growth variation in bivalves is still poorly understood, although several genes have been described as upregulated in fast-growing individuals. In the present study, we reared mussel spat of the species Mytilus galloprovincialis under diets below the pseudofaeces threshold (BP) and above the pseudofaeces threshold (AP). After 3 months, F and S mussels from each condition were selected to obtain 4 experimental groups: FBP, SBP, FAP and SAP. We hypothesized that the nurturing conditions during the growing period would modify the molecular basis of their growth rate differences. To decipher the molecular mechanisms underlying the growth variation, the gill transcriptomes for the four mussel groups... |

| Juvenile oysters (Crassostrea gigas) (produced in November 2009) reared under uniform hatchery conditions for 4 months were selected for extreme growth rate differences by repeatedly taking larger and smaller individuals to achieve weight differences > 30x between fast (F) and slow (S) growers. The physiological basis of differential growth was analyzed in experiments in June 2010, where components of energy gain (clearance and ingestion rates and absorption efficiency), energy loss (metabolic rates) and resulting scope for growth (J h(-1)) were compared for groups of F and S oysters fed three different ration levels (a parts per thousand 0.5, 1.5 and 3.0 mg of total particulate matter L-1). In both F and S oysters, a higher food ration promoted... |
