Abstract: ndividual difference is a widespread phenomenon throughout the animal kingdom. Consistent individual difference in fish behavior under different time and space conditions is known as “personality”, which is generally synonymous with “temperament” and “behavioral syndromes”. The personality reflects an individual’s life history strategy, and is closely related to the population dynamics, genetic variation and differentiated speciation. This paper expounded the definition and connotation of personality, and summarized the research progress of the classic behavioral traits (e.g. boldness, exploration, activity, aggressiveness and sociability) that are used to describe fish personality. The potentially neurobiological, physiological, genetic and ecological mechanisms in formation and maintenance of fish personality were discussed. Finally, the prospect of future theoretical research and application of fish personality was proposed from an ecological perspective.
