The objective of this study was to evaluate the effect of sodium alginate obtained from brown seaweed as a prebiotic supplement to the feed of reared sea bream (Sparus aurata). Addition of the alginate to a control diet was investigated at both concentrations 2% and 5%. Proximate composition in the flesh were not modified significantly by sodium alginate inclusion in the diet of the sea bream; however the fat and ash content in the specimens supplemented with 5% alginate were found to be significantly higher than those found in individuals who were fed the control diet. No significant differences in mineral content, fatty acid profiles, cholesterol content, texture parameters and sensory acceptability among the three studied groups. Results obtained in this study offer support for the use of alginate as a feed additive in sea bream diets since no significant effects were found in the flesh quality and characteristics of commercial size sea bream.
本研究旨在评估从褐藻中提取的海藻酸钠作为养殖真鲷（Sparus aurata）饲料的益生元补充剂的效果。在本研究中，分别以 2%和 5%的浓度向对照饲料中添加海藻酸钠。结果发现，在真鲷的饮食中添加海藻酸钠不会显著改变其肉质的基本成分，但在添加 5%海藻酸钠的样本中，脂肪和灰分含量明显高于对照组。三组之间的矿物质含量、脂肪酸分布、胆固醇含量、质地参数和感官接受度均无显著差异。本研究结果为海藻酸钠作为真鲷饲料添加剂的使用提供了支持，因为在商业规格真鲷的肉质和特性方面没有发现明显的影响。
