翘嘴鳜对光照强度及光色的选择行为
The selective behavior of Siniperca chuatsi to light intensity and color
摘要
Abstract
In order to investigate the effects of light on the domestication and behavior of Siniperca chuatsi,the behavioral activities were studied under different light intensities(dark area:10-20 lx,transition area:300-400 lx,and bright area:800-1 000 lx)and light colors(red,yellow,green,blue,and white).Through individual and group behavior experiments,the selection behavior of different sizes(3 cm,6 cm,12 cm)of S.chuatsi towards light intensity was investigated.The results showed that for the 3 cm group:both single-fish and multiple-fish showed significantly longer average residence time in the bright area than in the dark area and transition area(P<0.05).For the 6 cm group:both single-fish and multiple-fish showed significantly longer average residence time in the transition area than in the dark area and bright area(P<0.05).For the 12 cm group of S.chuatsi:both single-fish and multiple-fish showed significantly longer average residence time in the dark area than in the transition area and bright area(P<0.05).The study also explored the color preference behavior of 3 cm S.chuatsi through color selection experiments,and the results showed that S.chuatsi had a significant preference for yellow light.The study indicates that there are differences in the preference for light intensity among S.chuatsi,as well as individual and group preferences.As the size increases,S.chuatsi shows a more pronounced preference for weak light.关键词
