Abstract:
Passive acoustic monitoring (PAM) technology can obtain acoustic information of aquatic organisms without disturbing or damaging them, and use it for various ecological research and management activities. With the continuous improvement and advancement of shrimp aquaculture technology, shrimp farming density continues to increase, and problems such as low feed utilization and deterioration of water quality seriously constrain the rapid development of shrimp. The use of passive acoustic monitoring technology to achieve an intelligent automatic feeding system to improve feed utilization and alleviate water quality deterioration is the main way to solve the above problems. The article mainly describes the process of shrimp feeding and the factors affecting shrimp feeding behavior, summarizes in detail the research progress and application of passive acoustic monitoring technology in monitoring shrimp feeding acoustic signals, analyzes the advantages of the technology and the challenges faced in the future development, and at the same time, puts forward the trend of the future development of the existing problems, to provide a passive acoustic monitoring technology for shrimp aquaculture in the application and promotion. The results of this study are summarised in the following table.

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管理活动。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,饲料利用率低、水质恶化等问题严重制约对虾的快速发展。利用被动声学监测技术来实现智能化的自动投饲系统,提高饲料利用率和缓解水质恶化是解决上述问题的主要途径。文章主要阐述了对虾的摄食和其影响因素,总结了近些年来被动声学监测技术在对虾摄食发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发展的趋势,以期为自动投饲系统走向智能化提供参考。
