In order to solve the problem of feed waste and water pollution in the process of aquaculture, the study of fish feeding behavior has been paid much attention by the majority of researchers. Quantifying fish feeding behavior, extracting available parameters, and constructing a precise model are the effective ways to optimize feeding strategy. This paper summarized the main foraging sensory organs, quantitative indexes of predation and the characteristics of acoustic signals during feeding, and summarized the environmental factors that affect feeding behavior in the period of cultivation. The research progress, advantages and disadvantages of the two monitoring technologies were compared and analyzed, including computer vision based on visible and near-infrared light, and acoustic technology based on acoustic monitoring and sonar imaging. In view of the existing problems, this paper proposed methods to improve the feeding model accuracy and universality, and research potential and direction of passive acoustics, so as to provide reference for the intelligent feeding system.
