摘要:
摘要:为了探讨光色对水生生物生长和免疫的影响,本研究探讨了五种光照环境(黑暗、全光谱、绿光、蓝光和黄光)对脊尾白虾(Exopalaemon carinicauda)生长、消化和非特异性免疫相关酶活力的影响。结果显示:(1)全光谱组的增质量率(WGR)(63.76±0.34 %)、特定生长率(SGR)(1.63±0.03 %)和存活率(SR)(61.11±1.92 %)均显著高于其它4种光色(P<0.05);(2)绿光组的糜蛋白酶活力(4.02±0.38 U/mgprot)最高,显著高于其它4种光色(P<0.05);全光谱组的α-淀粉酶(α-AMS)活力(213.95±16.30 U/mgprot)最高,与绿光组和黑暗组之间差异不显著(P>0.05);黄光组的脂肪酶(LPS)活力(19.21±2.53 U/gprot)最高,与黑暗组、绿光组和蓝光组之间差异不显著(P>0.05);(3)绿光组的总超氧化物歧化酶(T-SOD)活力(33.26±7.08 U/mgprot)和总抗氧化能力(T-AOC)活力(2.31±0.23 单位/mgprot)均最高,与全光谱组之间差异不显著(P>0.05);全光谱组的过氧化氢酶(CAT)活力(17.27±1.58 U/mgprot)、酸性磷酸酶(ACP)活力(27.1±3.25 金氏单位/gprot)和碱性磷酸酶(AKP)活力(74.26±5.16 金氏单位/gprot)均最高,显著高于其它4种光色(P<0.05);黄光组的溶菌酶(LZM)活力(485.48±36.85 μg/ml)最高,其它4种光色之间差异不显著(P>0.05)。结果表明:本试验规格的脊尾白虾的生长和非特异性免疫能力在全光谱下最好,消化能力在绿光下较好。本研究可为脊尾白虾生长与免疫机制的基础理论研究提供参考依据。

Abstract:
Abstract: In order to investigate the effects of light color on the growth and immunity of aquatic organisms, the effects of five light colors (dark, full spectrum, green, blue and yellow light) on the growth, digestion and non-specific immune related enzyme activities of Exopalaemon carinicauda were studied. The results showed that: (1) WGR (63.76 ± 0.34%), SGR (1.63 ± 0.03%) and SR (61.11 ± 1.92%) of the full spectrum group were significantly higher than those of the other four light colors (P < 0.05); (2) Chymotrypsin activity (4.02 ± 0.38 U / mgprot) of the green light group was significantly higher than the other four light colors (P < 0.05); α - amylase (α - AMS) activity (213.95 ± 16.30 U / mgprot) of the full spectrum group was the highest and had no significant difference with the dark group (P > 0.05); Lipase (LPS) activityin (19.21 ± 2.53 U / gprot) of the yellow light group was the highest and had no significant difference with dark group, green light group and blue light group (P > 0.05); (3) The total superoxide dismutase (T-SOD) activity (33.26 ± 7.08 U / mgprot) and total antioxidant capacity (T-AOC) activity (2.31 ± 0.23 units / mgprot) of the green light group were the highest and had no significant difference with full spectrum group (P > 0.05); The activities of catalase (CAT) (17.27 ± 1.58 U / mgprot), acid phosphatase (ACP) (27.1 ± 3.25 Kim's units / gprot) and alkaline phosphatase (AKP) (74.26 ± 5.16 Kim's units / gprot) of the full spectrum group were significantly higher than the other four light colors (P < 0.05); The lysozyme (LZM) activity (485.48 ± 36.85 μ g / ml) of the yellow light group was the highest and had was no significant difference with the other four light colors (P > 0.05). The results indicated that the full spectrum was the best for growth and non-specific immunity and the green light was the best for digestion ability of the E. carinicauda. This study can provide a reference for the basic theoretical research on the growth and immune mechanism of E. carinicauda.
