摘要: 为探讨小球藻对大鳞副泥鳅生长、营养和风味物质的影响,以大鳞副泥鳅幼鱼为试验对象,设置对照组(仅投喂基础饲料)、藻粉组(投喂含有3%小球藻粉的饲料)和藻液组(投喂基础饲料并于养殖水体中添加浓缩小球藻液),进行45 d的养殖试验,并测定相关指标。结果表明:藻粉组和藻液组的增重率、特定生长率显著高于对照组(P<0.05)。各处理组粗脂肪含量显著下降(P<0.05),藻粉组中粗蛋白、总氨基酸、鲜味氨基酸、呈味氨基酸、不饱和脂肪酸含量均显著高于对照组(P<0.05),藻液组必需氨基酸含量有所升高但不显著(P>0.05),两组饱和脂肪酸含量显著低于对照组(P<0.05)。综上,添加小球藻能显著促进大鳞副泥鳅生长,优化营养,改善肌肉滋味和品质,且以藻粉添加效果更佳。

Abstract: In order to investigate the effects of Chlorella vulgaris(Beijerinck)on the growth, nutrition and flavor of Paramisgurnus dabryanus, three experimental groups were established: a control group(fed only basic feed), an algal powder group(fed feed containing 3% Chlorella vulgaris powder), and an algal liquid group(fed basic feed with concentrated Chlorella vulgaris liquid added to the aquaculture water). The aquaculture experiment was conducted for 45 d.The results showed that the weight gain rate and specific growth rate of the algae powder and algae liquid groups were significantly higher than those of the control group(P<0.05). The crude fat content of each treatment group decreased significantly(P<0.05), the crude protein, total amino acids, fresh amino acids, flavor amino acids and unsaturated fatty acids content of the algae powder group was significantly higher than that of the control group(P<0.05), the essential amino acids content of the algal liquid group was elevated but not significant(P>0.05), and the saturated fatty acids content of the two groups was significantly lower than that of the control group(P<0.05). In conclusion, the addition of Chlorella can significantly promote the growth, optimize the nutrition, and improve the muscle taste and quality of Paramisgurnus dabryanus, and the effect was better with the addition of algal powder.

Key words: Paramisgurnus dabryanus, Chlorella vulgaris, growth performance, nutritional components, flavor substances
