Abstract: China’s current aquaculture export volume and production of aquaculture products are in the forefront of the world. In order to ensure the quality of aquaculture products and human dietary health, it is particularly important to refine the feeding of aquaculture products and develop and improve precise feeding equipment. At present, the industry emphasizes the refinement, digitization and intelligence of aquaculture equipment. This article reviews the research progress of intelligent feeding systems based on four different perspectives such as vision, sound, passive self-demand and growth environment modeling and decision-making, and studies the development trend of intelligent feeding systems in aquaculture. Through digital and intelligent technology, precise management of feeding equipment is achieved to improve breeding efficiency. Emphasizing innovation is crucial for promoting the development of the aquaculture industry, in order to open up new ideas for the digital and precise development of aquaculture feeding equipment.
