Energy intake and genetic background are major determinants of muscle fat content in most animals, including man. We combined genetic selection and dietary energy supply to study the metabolic pathways involved in genetic and nutritional control of fat deposition in the muscle of rainbow trout (Oncorhynchus mykiss). Two experimental lines of rainbow trout, selected for lean (L) or fat (F) muscl...

Vitellogenin (vtg) was isolated from greenback flounder (Rhombosolea tapirina), rainbow trout, (Oncorhynchus mykiss) and Atlantic salmon (Salmo salar) plasma. The molecular weight of each native molecule, as determined by gel filtration, was 540, 383 and 557 kD respectively. With SDS-PAGE under reducing conditions, rainbow trout vtg dissociated into 1 major subunit (~154 kD), and Atlantic salmo...

We searched for quantitative trait loci (QTL) affecting upper temperature tolerance (UTT) in crosses between the Nauyuk Lake and Fraser River strains of Arctic charr (Salvelinus alpinus) using survival analysis. Two QTL were detected by using two microsatellite markers after correcting for experiment-wide error. A comparative mapping approach localized these two QTL to homologous linkage groups...

Rainbow trout, Oncorhynchus mykiss, is an important aquaculture species worldwide and, in addition to being of commercial interest, it is also a research model organism of considerable scientific importance. Because of the lack of a whole genome sequence in that species, transcriptomic analyses of this species have often been hindered. Using next-generation sequencing (NGS) technologies, we sou...
