摘　　要：被动声学监测(Passive acoustic monitoring, PAM)技术可在对水生生物不造成干扰或损害的情况下获取水生生物的声音信息,并利用这些信息进行各种生态研究和养殖活动管理。随着对虾养殖技术的不断提高和进步,对虾的养殖密度持续增加,但是饲料利用率低、水质恶化等问题严重制约对虾养殖的快速发展。利用被动声学监测技术可实现智能化的自动投饲,提高饲料利用率和缓解水质恶化。文章主要阐述了对虾的摄食过程及其影响因素,总结了近年来被动声学监测技术在对虾摄食声信号的研究进展和应用情况,分析了被动声学监测技术的优缺点,并针对存在的问题提出未来的发展趋势,以期为自动投饲系统走向智能化提供参考。Passive acoustic monitoring(PAM)technology enables the acquisition of acoustic information from aquatic organisms without causing disturbance or harm,facilitating various ecological studies and aiding in the management of aquaculture activities.As shrimp aquaculture technology advances,the industry’s scale and density are increasing.However,challenges such as low feed utilization and water quality deterioration have severely constrained the rapid development of the industry.PAM technology can be used to study sound in the environment by using it to understand shrimp feeding behaviour,guide feeding decisions,and implement intelligent automated feeding systems,thereby improving feed utilization and mitigating water quality deterioration problems.This article primarily discusses how shrimp feed,the factors affecting their feeding,and the acoustic characteristics of the feeding process,and reviews the latest research progress and application of PAM technology in detecting acoustic signals of shrimp feeding,as well as the challenges faced by the technology in its development.The advantages and limitations of PAM technology in shrimp aquaculture are analyzed,and the future development direction is proposed to address the problems of this technology.To provide a reference for the automatic feeding system to move towards intelligence,to promote the sustainable development of shrimp aquaculture.
