摘　　要：为考察代谢范围(aerobic scope, AS)对中华倒刺鲃(Spinibarbus sinensis)空间位置和群体行为的影响,在(25.4±0.2)℃条件下,测定该鱼种的代谢率,并计算AS。结果显示:随着摄食量的增加,中华倒刺鲃耗氧率明显增加,预测剩余AS与摄食量呈统计学意义上的负相关关系(p<0.001);摄食时间段对鱼群中个体的平均空间位置和1号位占比无统计学意义上的影响,但AS对鱼群中个体的这2个参数有统计学意义上的影响(p<0.001);与摄食前相比,摄食一段时间后群体的个体间距离有统计学意义上的增加(p<0.05)而群体极性有统计学意义上的降低(p<0.05)。上述结果提示AS对中华倒刺鲃个体的空间位置有明显影响,低AS个体占据群体领先地位的时间更长,摄食后群体中个体成员的凝聚力和群体协调性均有所降低。To investigate the effect of aerobic scope(AS)on the spatial location and group behavior of Qingbo(Spinibarbus sinensis),the metabolic rate was measured at(25.4±0.2)℃ and the AS was calculated.The results showed that:oxygen consumption rate increased significantly with increasing food intake,and its residual AS was predicted to be significantly negatively correlated with food intake(p<0.001);there was no significant effect of feeding time period on the mean spatial position of individuals in the shoal and the percentage of No.1 position,but AS had a significant effect on these 2 parameters for individuals in the fish population(p<0.001),the inter-individual distance of the shoal had a significant increase(p<0.05)and the group polarity had a significant decrease(p<0.05).The results above indicated that:the spatial position of Chinese barb individuals is significantly influenced by AS;individuals with low AS occupy the group lead for a longer period of time;furthermore,the cohesion of individual members of the group and group coordination both decrease after feeding.
