孔雀鱼幼苗在光场中的行为反应分析

采用光梯度法,探讨了孔雀鱼幼苗对红(波长为700 nm)、黄(580 nm)、绿(550 nm)、蓝(450 nm)及白色光的选择性及不同照度梯度下的行为反应.结果表明,孔雀鱼幼苗对5种颜色光表现出不同程度的趋光性和选择性,对蓝光的趋光性最强,其趋光率高达99%,相应的照度范围为1 500~2 000 lx,对红光的趋光性最小.

Analysis of behavioral response of guppy fry in optical field

This paper discussed the behavioral response of the guppy fry in different optical field.To identify the choice and response of guppy fry,this process used the method of optical grade under red light(700 nm),yellow light(580 nm),green light(550 nm),blue light(450 nm) and white light.The result showed a quite different phototaxis among 5 optical fields that the guppy fry displayed a high phototaxis of 99% under blue light with the illuminance of 1 500~2 000 lx while comparing with the low phototaxis under red light.
