摘要
【目的】考察颜色标记对鲫(Carassiu sauratus)幼鱼个性的影响及颜色保留时间。【方法】在(25.0±0.2)℃实验室条件下,将30尾实验鱼随机分为对照组和标记组,测定不同时间实验鱼的勇敢性、活跃性和好斗性,并在实验末期观察颜色掉落情况。【结果】1)对照组和标记组勇敢性的潜伏时间随测定次数的增加呈下降趋势(p<0.05),但标记组和对照组在测定Ⅰ(颜色标记前)的潜伏时间与测定Ⅱ(颜色标记后)均无统计学意义上的差异。2)标记组活跃性(如游泳速度、运动时间比及运动总距离)在3次测定间均无统计学意义上的差异,但有趣的是对照组活跃性的游泳速度随测定次数的增加呈下降趋势,该组的运动时间比及运动总路程却呈增加趋势(p<0.05)。3)标记组和对照组好斗性如警告次数、追随次数、冲咬次数在3次测定间均无统计学意义上的差异。4)鲫幼鱼的活跃性和好斗性在本实验中保持较高的重复性(p<0.001),但勇敢性在整个实验中重复性较差;鲫幼鱼在整个实验过程中标记的颜色掉落较少。【结论】颜色标记对鲫幼鱼的勇敢性、活跃性和好斗性均无明显影响。
[Purposes]To investigate the effects of in vitro color tagging on personality of juvenile Carassius auratus and the maintenance duration of in vitro color tagging,the experimental fish were randomly divided into the control group and the tagging group.[Methods]The experiment fish of the tagging group were treated before and after color tagging,and the boldness,activity and aggressiveness of both the control group and tagging group were measured before and after the color tagging.[Findings]Latency of both the tagging and control groups showed a decreased trend as measurement times increased(p<0.05),but no difference in the percentage latency of both the tagging and control groups was found between trailⅠand trailⅡ.There was no significant difference in activity(i.e.,swimming speed,percentage time on moving,and total movement distance)among three measurements in the tagging group.However,for the control group,swimming speed,and both percentage time on moving and total movement distance decreased and increased as measurement times increased respectively(p<0.05).The aggressiveness(i.e.,charge,chase,and bite)did not differ among three measurements in both the tagging and control groups.With the exception of boldness,both the activity and aggressiveness had high repeatability during the experiment,and percentage of disappearance color tagging was low in the C.auratus.[Conclusions]The present study showed that color tagging had no significant effect on the boldness,activity,and aggression of juvenile C.auratus.
