Changes in water quality significantly shape fish behavior, a crucial index reflecting the growth and welfare status of fish. Given the centrality of this relationship to aquaculture practices, a comprehensive understanding of how water quality dynamics influence fish behavior is imperative. While there have been some summaries of the effects of water quality parameters on fish physiology and growth, few reviews on their effects on fish behavior have been reported yet. This article reviews several water quality parameters which are of great concern in aquaculture from multiple facets of actual production, including physical parameters (water temperature and turbidity), chemical parameters (dissolved oxygen, salinity, pH, and inorganic nitrogen), and chemical pollutants (microplastics and crude oil), which have gained increasing attention from the researchers and aquaculture practitioners over the past decades. Variations in these water quality parameters can exert profound effects on fish physiology, metabolism, internal tissues and organs, and sensory perception, which influences fish behaviors such as swimming, schooling, feeding, predation, anti‐predation, aggression, courtship, as well as adaptive and stress‐related behaviors such as exploration, avoidance response, and anxiety‐like behavior. By synthesizing the behavioral changes caused by specific water quality parameters, this review aims to provide strong support for further water quality‐related research, thereby fostering environments conducive to both fish welfare and aquaculture productivity.

水质对鱼类行为的影响：水产养殖视角综述


水质的变化显着影响鱼类的行为，这是反映鱼类生长和福利状况的重要指标。鉴于这种关系与水产养殖实践的核心地位，必须全面了解水质动态如何影响鱼类行为。虽然已经对水质参数对鱼类生理和生长的影响进行了一些总结，但关于它们对鱼类行为影响的评论还很少。本文从实际生产的各个方面回顾了水产养殖中非常关注的几个水质参数，包括物理参数（水温和浊度）、化学参数（溶解氧、盐度、pH 值和无机氮）和化学污染物（微塑料和原油），这些参数在过去几十年中越来越受到研究人员和水产养殖从业者的关注。这些水质参数的变化会对鱼类的生理、新陈代谢、内部组织和器官以及感官知觉产生深远的影响，从而影响鱼类的行为，如游泳、成群结队、喂食、捕食、反捕食、攻击性、求偶，以及适应性和与压力相关的行为，如探索、回避反应和焦虑样行为。通过综合特定水质参数引起的行为变化，本综述旨在为进一步的水质相关研究提供强有力的支持，从而营造有利于鱼类福利和水产养殖生产力的环境。
