Abstract: Feed feeding is the main factor affecting the efficiency and cost of aquaculture. Judging and analyzing fish feeding behavior is the premise of intelligent feeding. In this paper the research on fish feeding behavior based on machine vision and the current situation of intelligent feeding technology using the changes of acoustic and water quality parameters is introduced. Then, the research progress on the analysis of fish feeding behavior and intelligent feeding with image processing, feed residue feedback and sound monitoring is introduced in detail. The advantages and existing problems of various research methods are also discussed. It is proposed that machine vision, acoustic and water quality parameters can be combined for comprehensive and multi-angle evaluation of feeding intensity to achieve intelligent feeding.

Key words: intelligent feeding, machine vision, feeding behavior, bait residue, ingestion sounds, water quality parameters
