FLOW VELOCITY ON FISH AND ITS APPLICATION IN RECIRCULATING AQUACULTURE SYSTEM

  • 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.
