Effect of ration size on fillet fatty acid composition, phospholipid allostasis and mRNA expression patterns of lipid regulatory genes in gilthead sea bream (Sparus aurata).
The effect of ration size on muscle fatty acid (FA) composition and mRNA expression levels of key regulatory enzymes of lipid and lipoprotein metabolism have been addressed in juveniles of gilthead sea bream fed a practical diet over the course of an 11-week trial. The experimental setup included three feeding levels: (i) full ration until visual satiety, (ii) 70 % of satiation and (iii) 70 % o...
متن کاملConjugated linoleic acid affects lipid composition, metabolism, and gene expression in gilthead sea bream (Sparus aurata L).
To maximize growth, farmed fish are fed high-fat diets, which can lead to high tissue lipid concentrations that have an impact on quality. The intake of conjugated linoleic acid (CLA) reduces body fat in mammals and this study was undertaken to determine the effects of dietary CLA on growth, composition, and postprandial metabolic variables in sea bream. Fish were fed 3 diets containing 48 g/10...
متن کامل‘Molecular characterization of a gilthead sea bream (Sparus aurata) muscle
Understanding the control of piscine fatty acid metabolism is important for determining the nutritional requirements of fish, and hence for the production of optimal aquaculture diets. The regulation and expression of carnitine palmitoyltransferase 1 (CPT1; EC No 2.3.1.21) are critical processes in the control fatty acid metabolism, and here we report a cDNA from gilthead sea bream (Sparus aura...
متن کاملFatty Acid Composition of Gilthead Sea Bream (Sparus aurata) Fillets as Affected by Current Changes in Aquafeed Formulation
The aquafeed industry is facing the lack of availability of fish meal and oil. The need of an economic and environmental sustainability has increased the use of plant-derived oils. In order to provide an overview of which ingredients are the most frequently used in GSB diet and as they affect the lipid composition of aquafeeds, we analyzed 26 feed samples collected from farmers. At the same tim...
متن کاملEffect of low dose diuron in oxidative state on the gilthead sea bream Sparus aurata
This study investigated effect of repeated exposure to low doses of diuron in gilthead sea bream by measuring the activities of the following antioxidant enzymes: Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione reductase (GR), glutathione transferase (GST), and DT-diaphorase (DTD). Examination of the lipid peroxidation (malondialdehyde contentMDA) and gluco...
