Abstract The applications status of underwater robots from 2007 to 2021 are summarized from the aspects of fishery environmental monitoring and aquatic animal behaviour monitoring, aquatic animal visual identification and capturing, and aquatic animal living environment maintenance. Key technologies of underwater robots applied in the fishery scenarios are reviewed, the research status and existing problems in structural design and shape optimization of underwater robot, underwater machine vision and image enhancement technology, underwater motion planning, and underwater environment information acquisition and transmission technology are analyzed. Finally, the future research directions of underwater robots dedicated to the fishery scenarios are prospected.
