AbstractThe use of new diets based on alternative sources to marine raw materials has been successful in several finfish species of interest to European aquaculture, including gilthead sea bream (Benedito-Palos et al., 2009). However, concerted efforts are still needed to undertake in depth the long-term consequences of feeding very low fish meal and fish oil diets (less than 10% of inclusion), and new knowledge is welcome to fill the gaps in a wide range of protein- and lipid metabolic disorders, closely related with reduced growth and survival. Therefore, there is a strong need for integrative tools that are capable of describing and predicting any metabolic disturbance of lipid metabolism in fish. In this scenario, the aim of the present study was to phenotype at the transcriptional level the tissue-specific regulation of lipid metabolism in nutritionally challenged fish, focusing on a panel of 40 genes which were selected as markers of fatty acid, phospholipid, acylglycerol and lipoprotein metabolism. The final aim is to define a data set of highly informative molecular markers of nutritional condition for a given tissue.
