流速对鱼类的影响及其在循环水养殖中的应用

FLOW VELOCITY ON FISH AND ITS APPLICATION IN RECIRCULATING AQUACULTURE SYSTEM

  • 摘要: 流速是循环水养殖中重要的环境因子。流速影响水体的动力, 有助于冲刷和清洗水体中的废物, 从而减少污染物浓度, 改善养殖水环境。流速刺激鱼类的游泳行为, 激发它们的活动性和游动欲望, 对消化和新陈代谢产生显著影响, 进而影响鱼类的成活率。此外, 流速对鱼类的生长发育、体型特征、心血管功能、免疫力和肉质都有重要作用, 目前已得到广泛研究, 并在实际生产中得到应用。因此, 文章综述了流速对养殖水质、养殖鱼类的游泳行为、生长生理及肌肉品质的影响。同时, 针对当前循环水养殖中流速调控存在的问题, 提出了今后流速智能调控的应对措施, 旨在为循环水养殖中流速的调控提供理论参考和指导意义。

     

    Abstract: Flow velocity is an important environmental factor in recirculating aquaculture systems. It increases the dynamics of the water, aiding in the flushing and removal of waste, which reduces pollutant concentrations and improves water quality. Additionally, flow velocity stimulates the swimming behavior of fish, increasing their activity and desire to swim. This heightened activity significantly impacts digestion and metabolism, ultimately affecting the survival rate of the fish. In addition, flow velocity influences the growth and development of fish, including their body shape, cardiovascular function, immunity, and meat quality. Extensive research has been conducted on the effects of flow velocity in aquaculture, leading to its practical application in the industry. This article provides an overview of the impact of flow velocity on water quality, fish swimming behavior, physiological growth, and muscle quality in recirculating aquaculture systems. Furthermore, it addresses current issues with flow velocity regulation in recirculating aquaculture and proposes future research directions for intelligent flow velocity control. The aim is to provide theoretical references and guidance for the regulation of flow velocity in recirculating aquaculture systems.
