过鱼效果监测技术研究和实践综述

Research and Practice of Monitoring Technology of Fish Passing Effect

摘要: 过鱼设施是保证河流生态系统健康的重要措施，过鱼设施的效果需要根据监测结果进行评估。本文梳理了国内外的过鱼效果监测技术，包括物理挂牌标记法、声呐法、无线电标记跟踪法、超声波标记跟踪法、应答器标记法、PIT射频标记跟踪法及电阻法，上述方法难以同时准确识别过鱼的数量和种类，需要研究基于鱼类动态图像的智能识别技术。

Abstract: Fish passing facilities are important measures to ensure the health of river ecosystem. The effect of fish passing facilities needs to be evaluated according to the monitoring results. This paper reviews the monitoring technology of fish passing effect internal and abroad, including physical tag method, sonar method, radio tag tracking method, ultrasonic tag tracking method, transponder tag method, pit radio frequency tag tracking method and resistance method. The above methods are difficult to accurately identify the number and species of fish passing at the same time. It is necessary to research the intelligent recognition technology based on fish dynamic image.
