摘 要 ：利用细胞计数法对不同光照强度、光谱成分、光周期对蒙古裸腹摄食强度的影响进行了研究。结果表明 :光强在 70 0 0 lx时蒙古裸腹对小球藻的摄食强度最高 ,成的滤水率和摄食率分别为 0 .5 2 8± 0 .0 0 9ml/ (ind· h)和 1.113± 0 .0 15μg C/ (ind· h) ,幼的滤水率分别为 0 .4 95± 0 .0 14 ml/ (ind· h)和 1.0 5 1± 0 .0 0 8μg C/ (ind· h)。在蓝光下蒙古裸腹对小球藻的摄食强度明显高于绿光组。光周期 L∶ D为 12∶ 12时蒙古裸腹对小球藻的摄食强度最高 ,成和幼的滤水率分别为0 .4 6 1和 0 .35 5 ml/ (ind· h) ,摄食率分别为 1.2 4 2和 1.0 0 5μg C/ (ind· h) ,而在 L∶ D为 0 :2 4时摄食强度最差 ,成和幼的滤水率分别为 0 .0 70和 0 .0 5 0 ml/ (ind· h)。在自然光照下 ,蒙古裸腹对小球藻的摄食强度在 7∶ 0 0～ 11:0 0和 15 :0 0～ 19:0 0最高。

Abstract:Moina mongolica Daday, which appears to be the only halophilic species of Moina in the old world, distributes from north Africa, across the Middle East and the Central Russia, Aral Sea, Spain. It is a new record of Cladocera in China. Dalian Fisheries University has initiated a saline water research program including its autecology, reproductive biology, feeding ecology and perspective as live food for marine fish larviculture. However, the effect of light on the ingestion capacity is not reported. A di...
