The use of passive acoustic monitoring (PAM) has recently been integrated with other noninvasive ethological methodologies to enhance the understanding of shrimp feeding behaviour, as their mandibles emit click sounds during food intake. This review aims to compile recent advances and various applications of PAM in assessing shrimp feeding behaviour under controlled laboratory and farm conditions. It includes a description of key concepts, terms and general methodologies in the field of bioacoustics to facilitate understanding of acoustic characterisation, specific methodologies and the main uses of PAM in shrimp research. Among the primary contributions of PAM in laboratory studies are acoustic characterisation of clicks and mandibular structures associated with their emission for different species; variations in acoustic click parameters related to animal size, feed texture and pellet size; and effects on feeding behaviour caused by shrimp size, stocking density and specific characteristics of artificial diets (texture, formulations, additives and pellet sizes). Finally, future perspectives and recommendations for laboratory studies using PAM are provided. The review highlights the contribution of PAM, which, allied with other ethological methodologies, emerges as a novel tool for researching shrimp behaviour and optimising feed management in aquaculture.

被动声学监测在实验室和养殖条件下对虾摄食行为评价中的最新进展和应用


被动声学监测 （PAM） 的使用最近已与其他无创行为学方法相结合，以增强对虾摄食行为的理解，因为它们的下颌骨在进食过程中会发出咔哒声。本综述旨在汇编 PAM 在受控实验室和养殖条件下评估虾摄食行为的最新进展和各种应用。它包括对生物声学领域关键概念、术语和一般方法的描述，以促进对声学特性的理解、具体方法以及 PAM 在虾研究中的主要用途。PAM 在实验室研究中的主要贡献包括不同物种的咔嗒声和与其发射相关的下颌结构的声学特征;与动物大小、饲料质地和颗粒大小相关的声学点击参数的变化;以及虾的大小、放养密度和人工饲料的特定特性（质地、配方、添加剂和颗粒大小）对摄食行为的影响。最后，提供了使用 PAM 进行实验室研究的未来前景和建议。该综述强调了 PAM 的贡献，它与其他行为学方法相结合，成为研究对虾行为和优化水产养殖饲料管理的新工具。
