鱼类个性测定方法研究进展

动物个性是指在不同时空条件下动物种内个体间行为的稳定差异。鱼类个性的研究历史已超过50年,但不同时期和不同研究的鱼类个性测定方法存在较大差异,缺乏一个规范的用于量化鱼类个性研究的方法论。本文作者认为,关注鱼类个性的常规测定方法,了解现有个性定义及其生态学意义,规范鱼类个性的常规实验方法是有必要的。本文所涉及的个性是指狭义上的个性,即对勇敢性、探索性、活跃性、好斗性和社会性等个性的研究方法进行综述,规范了鱼类个性的常规测定方法及注意事项,并对过往研究中鱼类个性测定方法的不足之处进行了讨论和展望。

A review on methodology for the measurement of personality in fish

Animal personality refers to the consistent individual differences in behavioral traits across temporal and spatial scales.The research history of fish personality has been more than 50 years.There were great differences in the methods of measuring fish personality in different periods and studies,without a normative methodology for quantifying personality in fish.We suggest that it is necessary to pay attention to conventional measurement methods of fish personality,and to understand the definition of personality and its ecological significance,and to standardize the conventional experimental methods of fish personality.In this review,we focused on the narrow sense of personality such as boldness,exploration,activity,aggressiveness as well as sociability.We summarized the measurement methods of personality in order to standardize conventional measurement methods and precautions of fish personality.Finally,we discussed deficiencies of the measurements of fish personality in literature.
