The objective of the study was to identify genes and proteins that are involved in the control of muscle fat deposition in rainbow trout. We analyzed the combined effects exerted by genetic selection and dietary treatment, which are the two main factors that can be used to manage body fat content. Two lines of rainbow trout, obtained after 3 generations of divergent selection for high or low muscle fat content, were fed diets containing either 10% or 23% lipids (% dry matter), for six months. We analyzed the activity and gene expression of key enzymes involved in energy utilization, and performed a more global approach through transcriptome (nylon microarray) and proteome (twodimensional electrophoresis) analysis. We analyzed the liver, which is the centre...

Replacement of dietary fish oil by a blend of vegetable oils for more than a year does not affect growth, hepatic lipogenesis and tissue lipid uptake in rainbow trout and European seabass. However, this replacement decreases plasma cholesterol level in both species and LDL amount in rainbow trout. Such replacement does not affect muscle lipid content of fish but modifies fatty acid composition of fish flesh which reflects in most part that of dietary lipid source.  Increasing dietary lipid level inhibits hepatic lipogenesis but does not modify tissue lipid uptake in seabass and in two trout lines selected for muscle lipid level. In seabass, dietary lipid level had a lower impact on growth and lipid metabolism than rearing temperature. In this species,...
