摘　　要：紫外光A波段(Ultraviolet A,UVA)是自然光的重要组成部分,具有一定的生态功能。本研究选取450尾体重为(9.56±0.10)g的凡纳滨对虾(Penaeus vannamei)以光周期为12L︰12D的全光谱LED灯[光强(1.00±0.02)W/m^(2)]作为背景光源,在不同UVA[光强(1.00±0.02)W/m2]补光时间(0 h,T_(0 h);2 h,T_(2 h);4 h,T_(4 h);8 h,T_(8 h);12 h,T_(12 h))下进行为期28 d的养殖实验。结果显示,在不同UVA补光时长下,对虾肌肉中水分和粗灰分含量无显著差异,T2 h和T4 h组的粗脂肪含量显著增加,T2 h组的粗蛋白显著高于T4 h组外的其他组(P<0.05),T8 h和T12 h组的粗脂肪显著低于其他各组(P<0.05),但两组间差异不显著;T2 h和T4 h组氨基酸总量、必需氨基酸含量和赖氨酸含量均显著高于其他组(P<0.05);凡纳滨对虾饱和脂肪酸(SFA)含量为27.85%~40.70%,单不饱和脂肪酸(MUFA)含量为10.63%~16.31%,多不饱和脂肪酸(PUFA)含量为38.81%~49.61%,其在T2 h和T4 h组显著高于其他各组(P<0.05),且在两组间无显著差异。综上所述,2~4 h的UVA补光时间能够改善凡纳滨对虾肌肉的营养成分。UVA is an important component of natural light and has certain ecological functions.However,it remains unclear whether UVA affects the nutrient composition of Penaeus vannamei.We built a supplementary light culture system for P.vannamei and used classic nutrient composition analysis techniques to analyze the nutrient,fatty acid,and amino acid composition of the shrimp muscle tissue after different supplementary UVA light durations.Our results provide a theoretical reference for the technological improvement of P.vannamei culture.A total of 450 shrimps[weighing(9.56±0.10)g]were included in a 28-day culture experiment with background lighting of 12L:12D photoperiod with full spectrum LED light[light intensity(1.00±0.02)W/m2].The experimental design randomly included different UVA[light intensity(1.00±0.02)W/m2]supplementation(0 h,T0 h;2 h,T2 h;4 h,T4 h;8 h,T8 h;12 h,T12 h).The results revealed no significant variation in the water and crude ash content of the shrimp muscles after different UVA light durations.The crude fat content increased significantly in the T2 h and T4h groups(P<0.05).The crude protein was significantly higher in the T2h group than that in the other groups(P<0.05),except the T4h group.The crude fat was significantly lower in the T8 h and T12 h groups than that in all other groups(P<0.05),but there was no significant difference between the T8 h and T12 h groups.Among saturated fatty acids(SFA)in the shrimp muscle,C16:0 was highest(with 17.19%-27.03%),followed by C18:0(with 7.82%-10.99%),and both were significantly higher in the T2 h and T4h groups(P<0.05).The dominant monounsaturated fatty acids were C18:1n-9(with 8.46%-14.21%),and were significantly higher in the T2h and T4h groups(P<0.05).Linoleic acid and EPA were significantly higher in the T2 h and T4 h groups(P<0.05).The SFA content was 27.85%-40.70%,MUFA was 10.63%-16.31%and PUFA was 16.31%.The total content of n-3 and n-6 polyunsaturated fatty acids was significantly higher in the T2 h and T4 h groups than those in the other groups(P<
