作者任纪龙,魏平平,费凡,代明允,马贺,高东奎,宋昌斌,陈涛,刘鹰(2019)在《LED光谱对舌齿鲈幼鱼摄食、生长和能量分配的影响》一文中研究指出:在海水循环水养殖系统中,分别设置白光(λ400~780 nm)、红光(λ630 nm)、黄光(λ595 nm)、绿光(λ530 nm)、蓝光(λ455 nm)5组不同LED光谱处理组,研究5种不同LED光谱对舌齿鲈幼鱼[(29.91±0.39) g、(13.78±0.35) cm)]摄食、生长和能量分配的影响。结果显示,不同LED光谱对舌齿鲈幼鱼摄食、生长和能量分配具有显著性影响。红光谱下舌齿鲈幼鱼生长较好(41.09±5.70) g,蓝光谱下舌齿鲈幼鱼生长较差(36.02±4.18) g;蓝光谱下舌齿鲈幼鱼DGC(daily growth coefficient)显著低于其他各组,其他各组之间差异不显著;5组LED光谱处理组舌齿鲈幼鱼摄食率存在显著性差异,其中红光谱摄食率最高。类胰岛素生长因子IGF-1和IGF-2测定结果表明,白光谱下IGF-1的mRNA表达量最高;黄光谱下IGF-2的mRNA表达量最高。能量分配方面,红光谱下舌齿鲈幼鱼排粪能和代谢能较低,摄食能和生长能较高;蓝光谱下舌齿鲈幼鱼排粪能较高,摄食能和代谢能较低,生长能最低。对舌齿鲈幼鱼肌肉和肝脏RNA/DNA比值测定结果表明,蓝光谱下,舌齿鲈幼鱼肝脏RNA/DNA比值显著高于其他各组;蓝光谱和白光谱下舌齿鲈幼鱼肌肉中RNA/DNA比值存在显著性差异,其他各组之间不具有显著性差异。研究表明,红光谱下舌齿鲈幼鱼摄食、生长均表现较好,且红光谱下舌齿鲈幼鱼具有较高的摄食能和生长能;蓝光谱下舌齿鲈幼鱼摄食、生长表现较差,排粪能较高,生长能较低。因此,红光谱对舌齿鲈幼鱼摄食、生长具有积极影响;蓝光谱对舌齿鲈幼鱼摄食、生长具有不利影响。
