| 在循环水养殖实验系统中,设置红色(λ625-630nm)、绿色(λ525-530nm)、白色(λ400-780nm)、黄色(λ590-595nm)、蓝色(λ450-455nm)共五个光色处理组,进行欧洲舌齿鲈(Dicentrarchus labrax)幼鱼(29.91±0.39 g,13.78±0.35 cm)50 d的动物实验,研究不同LED光色对欧洲舌齿鲈幼鱼抗氧化能力和消化能力的影响。结果表明,红光组的欧洲舌齿鲈幼鱼超氧化物歧化酶(SOD)活力显著高于其他光色组的欧洲舌齿鲈幼鱼(P<0.05),绿光、白光、黄光和蓝光组的SOD活力没有显著性差异。红光组的还原性谷胱甘肽(GSH)含量显著高于其他光色组(P<0.05)。绿、白光组与黄、蓝光组的GSH含量之间有显著性差异(P<0.05)。红光组过氧化氢酶(CAT)活力显著高于其他光色组(P<0.05),白光组的CAT活力显著低于其他光色(P<0.05)。黄光组的胃蛋白酶活力显著高于红、绿、白光组的胃蛋白酶活力(P<0.05),绿光组的胃蛋白酶活力显著低于其他光色组的胃蛋白酶活力。红、绿、蓝光组的淀粉酶活力要显著高于白、黄光组的淀粉酶活力(P<0.05)。红、绿、蓝光组的淀粉酶活力没有显著性差异,黄、白光组的淀粉酶活力没有显著性差异。白光组纤维素酶活力显著高于其他光色组(P<0.05),绿光组的纤维素酶活力显著高于红、蓝光组的纤维素酶活力(P<0.05),黄光组的纤维素酶活力和绿、红、蓝光组纤维素酶活力都没有显著性差异。综上,红光的欧洲舌齿鲈抗氧化能力强,能有效应对氧化应激。黄光和红光下欧洲舌齿鲈消化能力强。 |

| Abstract: |
| In the recirculating aquaculture experiment system, five light color treatment groups of red(λ625-630nm), green(λ525-530nm), white(λ400-780nm), yellow(λ590-595nm) and blue(λ450-455nm) are setted, animal experiments of sea bass (Dicentrarchus labrax) juveniles (29.91±0.39 g, 13.78±0.35 cm) to study the effects of different LED light colors on the antioxidant capacity and digestibility in 50 days. The results show that the activity of superoxide dismutase (SOD) in the red light group was significantly higher than that in other light color groups (P<0.05), and there is no significant difference of SOD activity in the green, white, yellow and blue light groups. The content of reduced glutathione (GSH) in red light group is significantly higher than that in other light color groups (P<0.05). There is a significant difference between the green and white light groups, and there is a significant difference between yellow and blue light groups (P<0.05). The activity of catalase (CAT) in the red light group is significantly higher than that in other light color groups (P<0.05), and the CAT activity in the white light group is significantly lower than that in other light colors (P<0.05). The pepsin activity of yellow light group was significantly higher than that of red, green and white light groups (P<0.05). The pepsin activity of green group is significantly lower than that of other light color groups. The amylase activity of the red, green and blue light groups is significantly higher than that of the white and yellow light groups (P<0.05). There is no significant difference in the amylase activity between the red, green and blue light groups. There is no significant difference in the amylase activity between the yellow and white light groups. The cellulase activity of the white light group is significantly higher than that of other light color groups (P<0.05). The cellulase activity of the green light group is significantly higher than that of the red and blue light groups (P<0.05). There is no significant difference of cellulase activity in the green, red and blue light groups. In summary, Sea bass juveniles in red light has strong antioxidant capacity and can effectively cope with oxidative stress. Under the yellow light and red light, the sea bass juveniles has strong digestion ability. |
