摘要
选用红、白、蓝、绿4种颜色的光,每种颜色光分别取6种不同光照度,研究了鲤Cyprinus carpio对不同颜色、不同照度光的趋向性。结果表明:不同颜色的光对鲤诱集效果的影响大小依次为白光>红光>蓝光>绿光,4种颜色的光在各照度下对鲤的最大平均趋集率分别为白光61.0%、红光45.0%、蓝光42.0%、绿光27.1%;光照度对鲤的趋集率有显著影响(P<0.05),光照时间对鲤的趋集率影响不显著(P>0.05)。
Attraction of different colors （white, red, blue and green） and six illuminance of light to common carp Cyprinus carpio was investigated to elucidate the phototaxis of common carp. The results showed that the attraction of the different colors of light ranged in descendant order as the following： white 〉 red 〉 blue 〉 green. The maximum aggregation rate under white, red, blue, and green light was 61.0%, 45.0%, 42.0% and 27.1%, respectively. There was a significant effect of illuminance on aggregation, but no significant difference between aggregation rate and illumining time.
