摘  要：
鱼穿梭格栅的行为和之后在格栅一侧的群聚行为是直接影响活鱼分级效果的关键因素。设计一套由玻璃水槽、变色LED灯、摄像头和电脑等组成的试验平台,并使用Matlab软件进行黑鲷(Acanthopagrus schlegeli)行为视频的分析,以此探究分级格栅的存在对黑鲷行为的影响,以及黑鲷对格栅颜色、材质和光色的偏好,并测试格栅和光照组合措施对黑鲷穿梭和群聚行为的影响效果。结果显示:格栅的存在对黑鲷在水槽内的游动产生了显著的抑制,黑鲷并未表现出喜好在格栅中穿梭的行为;格栅颜色的存在进一步抑制了黑鲷穿梭格栅的活跃程度,黑鲷对红色和蓝色格栅较为排斥,对绿色和无色透明格栅的排斥性较低;黑鲷对银色钢质格栅最为排斥,而对透明亚克力材质格栅排斥性最低;黑鲷对蓝色光有极高的趋光性,对红色光有强避光性。在黑鲷的格栅分级系统设计时,可引入光触发自分级技术,在格栅两侧分别设置蓝、红色光,有助于实现迅速且稳定的分级。该研究结果可对鱼类分级装备及其辅助设施的研发提供一定的参考。

摘  要：
The key factors that directly affect the grading efficiency of live fish are the behaviors of fish shuttling through the grille and congregating on one side of grille after shuttle.An experimental platform consisting of glass tank,LED lamps,camera and computer was designed,and videos of Acanthopagrus schlegeli behavior were analyzed by Matlab,the purpose of which was to study the effects of graded grille on the behavior of Acanthopagrus schlegeli and the preference of Acanthopagrus schlegeli for grille colors,materials and light colors,and test the effects of grille and light combination on the shuttle and congregation behavior of Acanthopagrus schlegeli.The results showed that the presence of grilles significantly inhibited the swimming of Acanthopagrus schlegeli in the tank,and Acanthopagrus schlegeli did not show a preference for shuttling through the grilles; the grille colors further inhibited the activity of Acanthopagrus schlegeli to shuttle through the grilles,and Acanthopagrus schlegeli is more repulsive to red and blue grilles and less repulsive to green and colorless transparent grilles; Acanthopagrus schlegeli is most repulsive to silver steel grilles and least repulsive to transparent PMMA grilles; Acanthopagrus schlegeli has high phototaxis to blue light and strong photophobism to red light.In the design of grille grading system of Acanthopagrus schlegeli,the light-triggered self-grading technology can be introduced,and blue and red light can be set on both sides of the grille,which is conducive to achieving rapid and stable grading.The results can provide some references for the research and development of fish classification equipment and auxiliary facilities.
