摘要(Abstract)：

研究中国明对虾(Fenneropenaeus chinensis)稚虾在2种光照强度和2种光照周期相互搭配下的生长。实验在水族箱内进行,投喂人工配合饲料,实验设14L∶10D-6μmol.m-2.s-1(14∶10W),14L∶10D-60μmol.m-2.s-1(14∶10s),18L∶6D-6μmol.m-2.s-1(18∶6W)和18L∶6D-60μmol.m-2.s-1(18∶6s)4种光照处理,持续35d。主要结果:1.4种光照处理下,中国明对虾的生长(SGRd)不同。其中,14∶10W和18∶10W下,对虾的生长(SGRd)较快,与其他光照处理相比差异达到显著水平(P<0.05),而14∶10W和18∶10W,14∶10s和18∶6s处理间的差异不显著(P>0.05);2.4种光照处理下,中国明对虾的摄食率(FId)差异不显著(P>0.05);3.4种光照处理下,中国明对虾的食物转化效率(FCEd)不同。其中,14∶10W和18∶6W下,对虾的食物转化效率较大,与其他光照处理相比差异达到显著水平(P<0.05),而14∶10W和18∶10W,14∶10s和18∶6s处理间的差异不显著(P>0.05);4.在本实验条件下,光照强度对中国明对虾的生长产生显著的影响(P<0.05),光照周期的影响不显著(P>0.05),光照强度和光照周期间的交互作用不明显(P>0.05)。因此,从节约能源的角度出发,14L∶10D-6μmol.m-2.s-1可能是中国明对虾集约化养殖较好的光照条件。
