Four practical diets containing plant ingredients and fish meal (50:50) as protein sources and supplemented with 0, 0.1, 0.25 and 0.5% scFOS were fed to triplicate groups of fish for 8weeks. Growth performance, feed efficiency and nitrogen retention were higher at 25°C. In fish reared at 18°C, there was a positive correlation between dietary scFOS concentration and growth. At 18°C, liver glycogen was higher in fish fed the control diet, while at 25°C it was higher in fish fed the 0.5% scFOS diet. Plasma cholesterol LDL was lower in fish fed 0.25% scFOS diet, and in fish reared at 18°C plasma glucose was higher in fish fed the 0.1% scFOS diet. Glucose 6-phosphate dehydrogenase, fatty acid synthetase and aspartate aminotransferase (ASAT) activities were higher in fish reared at 18°C, whereas alanine aminotransferase activity was higher in fish reared at 25°C. scFOS affected ASAT activity, which was lower in fish fed 0.25% scFOS diet. Although, scFOS seemed to have no major effects on gilthead sea bream metabolism, the positive correlation between dietary prebiotic incorporation and growth at 18°C indicates a beneficial effect of scFOS in fish reared at low temperatures.
