| 摘要: |
| 以鱼粉、南极磷虾粉和豆粕为蛋白源，以南极磷虾粉蛋白分别替代饲料中的0（对照组）、20%、40%、60%的鱼粉蛋白制成4种等氮等能的饲料，并以此饲料饲喂大菱鲆(37.36±2.12g)56 d。试验结果显示，饲料中南极磷虾粉水平对大菱鲆的成活率及特定生长率（SGR）没有显著性影响（P>0.05）；对各组的饲料干物质表观消化率均有显著性影响（P<0.05），替代40%组与替代60%组蛋白质表观消化率较对照组有显著性差异（P<0.05）；对大菱鲆血清中的碱性磷酸酶（AKP）、酸性磷酸酶（ACP）、溶菌酶及总超氧化物歧化酶（T-SOD）活力无显著性影响（P>0.05）。大菱鲆各组间肌肉中氟残留量没有显著性差异（P>0.05），且肌肉中氟含量均在可食用范围内，大菱鲆各组间骨骼中氟残留量均有显著性差异（P<0.05）。 |

| Abstract: |
| The effects of partial replacement of fish meal (FM) with meal made from Antarctic krill Euphausia superba as protein source in the diets for turbot Scophthalmus maximus on growth, non-specific immunity and fluoride retention were studied. Four experimental diets were prepared using an FM diet as the control. The other diets included Antarctic krill where 20%, 40% or 60% of the dietary FM protein was replaced by the protein from Antarctic krill. All diets were iso-nitrogenous and iso-caloric. Four diets were fed to groups of turbot(37.36±2.12 g) for 8 weeks. Experimental results showed that in fish fed diets containing Antarctic krill, survival, specific growth rate (SGR), alkaline phosphatase(AKP), acid phosphatase (ACP), lysozyme (LZM) and total superoxide dismutase(T-SOD)were significantly different compared with fish fed the control diet(P>0.05). The apparent digestibility of each experimental group has significant difference (P<0.05), and the protein digestibility rate of 3(40) group and 4(60) group had significant difference with the control group (P<0.05). The fluoride retention in muscles of each experimental group has no significant difference (P>0.05), but in bones, each experimental group has significant difference (P<0.05). |
