Abstract: 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.

Key words: personality, measurement method, boldness, exploration, activity, aggressiveness, sociability.
