生产活动造成的广泛水污染是水产养殖业需要解决的关键问题。水质动态监测是了解水质和鱼苗生长状况的重要手段。本文提出了一种低成本、低噪声、实时监测和自动反馈的仿生机器鱼，用于水产养殖中多种水质参数的动态监测。仿真分析表明，该仿生机器鱼在16 rad/s的摆动角速度下，具有更快的游动速度和更稳定的姿态控制。通过控制双关节的胸鳍和尾鳍，实现了快速的游泳速度（0.4 m/s），表现出各种类型的运动，如直线游泳，避障，转弯，潜水和浮出水面。作为应用演示，将仿生机器鱼放置在湖泊中进行现场取水和参数检测。水温、酸碱度、浊度等水质参数的相对平均偏差分别为1.25%、0.07%、0.94%，满足水质参数检测精度要求。在未来，仿生机器鱼将有利于监测水质、鱼类种群和行为，提高水产养殖的效率和生产力，并为科学教育和海洋探索提供有趣的工具和技术。
The extensive water pollution caused by production activities is a key issue that needs to be addressed in the aquaculture industry. The dynamic monitoring of water quality is essential for understanding water quality and the growth of fish fry. Here, a low-cost, low-noise, real-time monitoring and automatic feedback biomimetic robotic fish was proposed for the dynamic monitoring of multiple water quality parameters in aquaculture. The biomimetic robotic fish achieved a faster swimming speed and more stable posture control at a swing angular velocity of 16 rad/s by using simulation analysis. A fast swimming speed (0.4 m/s) was achieved through the control of double-jointed pectoral and caudal fins, exhibiting various types of movements, such as straight swimming, obstacle avoidance, turning, diving, and surfacing. As a demonstration of application, bionic robotic fish were placed in a lake for on-site water sampling and parameter detection. The relative average deviations in water quality parameters, such as water temperature, acidity and alkalinity, and turbidity, were 1.25%, 0.07%, and 0.94%, respectively, meeting the accuracy requirements for water quality parameter detection. In the future, bionic robotic fish are beneficial for monitoring water quality, fish populations, and behaviors, improving the efficiency and productivity of aquaculture, and also providing interesting tools and technologies for science education and ocean exploration.
