摘　　要：为探究光唇鱼对光色的偏好性以及这种偏好性是否存在昼夜差异,利用行为学方法分析比较了光唇鱼鱼群在黑暗以及白、红、黄、绿、蓝光5种LED单色光照明环境下的趋集率。结果表明,日间光唇鱼最受蓝光吸引,白光和绿光次之,而黄光对其具有趋避作用(P<0.05),夜间蓝光对光唇鱼最具吸引力,其次为白光和绿光,红光和黄光下的趋集率最低,且该鱼夜间对蓝光的偏好性较日间更为明显。总之,短波光尤其是蓝光能够吸引光唇鱼群体,说明存在明确的光谱偏好性且这种偏好性存在一定的昼夜差异。In order to explore the light colour preference and whether there is a day-night difference in the preference of Acrossocheilus fasciatus,the aggregation rate of A.fasciatus population in dark and under 5 kinds of LED monochromatic spectra environment(including white,red,yellow,green and blue lights)were compared by using behavior method.The results showed that,in the daytime,A.fasciatus population had an obvious preference to blue light,the next was white or green light,and there was an obvious avoiding effect of yellow light on the fish(P<0.05).The blue light was the most attractive to A.fasciatus in night,the next was white or green light,and the aggregation rate under red or yellow light were the lowest.The preference of A.fasciatus to blue light in night exceeded that in the daytime.In sum,short-wavelength light,especially blue light,is attractive to A.fasciatus,which suggested that A.fasciatus had a definite spectral preference with a diurnal bias.
