摘　　要：被剪去触角的日本沼虾经过暗适应12h后,在不同波长的红光(750nm),黄光(580nm),蓝光(400nm),绿光(560nm)下,其平均摄食量差异极显著。在红光和绿光光照区域内的平均摄食量为65.71％和61.15％,远大于蓝光和黄光光照区域内的41.86％和33.08％。同样经过12h的暗适应后,在无饵料的情况下,日本沼虾的趋光行为为红光的频次最高。The Macrobrachium nipponenses which had been get rid of their antennas were trained in a darkroom 12 hours and they were given light of different wavelength (red 750nm,yellow 580nm,blue 400nm,green 560nm). There were significant differences among the feeding quantities . The feeding quantity under the red and green light(65. 71% and 61. 15% ) is higher than that under the yellow and blue light(41. 86% and 33.08% ). Under the same condition, we observed the action of them for 30 minutes. At this time there were no baits under each light. It is observed that phototaxis of the Macrobrachium nipponenses under the red light is the highest.
