Progress in the study of the feeding behaviour of the shrimp based on passive acoustics
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.
