摘　　要：鱼类通过觅食获取机体所必需的营养物质。个性可能对鱼类的觅食速率产生重要影响,但目前二者之间的关联仍存在较大的不确定性。以德玛森小岩鲷(Chindongo demasonis)为实验对象,分别测定活跃性、攻击性、探索性和社会性,以及在空间探索觅食实验和控制抑制觅食实验中的觅食速率,并分析了不同个性特征之间的关联以及个性对觅食速率的影响。结果显示:德玛森小岩鲷的活跃性与探索性、攻击性均呈统计学意义上的正相关关系(p<0.05),探索性与社会性呈统计学意义上的负相关关系(p<0.05);空间探索觅食实验中实验鱼首次出适应装置的历时、首次进入食物区历时和首次摄食历时均与活跃性呈统计学意义上的负相关关系(p<0.05),控制抑制觅食中首次摄食历时与攻击性呈统计学意义上的正相关关系(p<0.05),表明较活跃的个体在空间探索觅食实验中完成觅食活动所需时间更短、觅食速率更高,而个性会对鱼类的觅食速率产生重要影响。研究提示活跃性较强的个体觅食动机更强烈,且探索空间能力也更强;攻击性较强的个体控制抑制的能力较弱,需要花费更长的时间完成觅食活动。Fish obtain essential nutrients through foraging.Personality may have a significant impact on the foraging efficiency of fish,but the correlation between them still remains uncertain.The Chindongo demasonis was selected as research object,and its activity,aggressiveness,exploration,and sociability were measured.Furthermore,the foraging efficiency of C.demasonis individuals were also investigated through spatial exploration foraging experiment and inhibitory control foraging experiment.The relationships between different personality traits and the influence of personality on foraging efficiency were analyzed.The results revealed a significant positive correlation between activity and both exploration and aggressiveness in C.demasonis(p<0.05).Additionally,exploration showed a significant negative correlation with sociability(p<0.05).In spatial exploration foraging experiment,C.demasonis’s latency to emerge,latency to enter food area,latency to eat food were all negatively correlated with activity(p<0.05);in inhibitory control foraging experiment,C.demasonis’s latency to eat food showed a positive correlation with aggressiveness(p<0.05),indicating that more active individuals had higher foraging efficiency in this experiment.This suggests that individuals with stronger activity are more motivated for foraging,and their spatial exploration ability is also stronger;stronger aggressiveness exhibit weaker inhibitory control performance and need longer time to finish foraging.Personality plays a crucial role in the foraging efficiency of fish.
