As a vital component of pelagic fisheries， the fishing efficiency of tuna purse seine operations is heavily reliant on a multi-platform， cooperative fish school detection system. This system integrates a variety of technological approaches， including underwater acoustic detection （e.g.， sonar）， sea surface observation （e.g.， radar）， and aerial detection （e.g.， helicopters）， forming a three-dimensional detection network that covers the vertical water column， sea surface， and airspace. While these technologies have significantly enhanced fishing efficiency， several challenges remain. These include the subjective interpretation of radar and acoustic signals， limited adoption of high-efficiency equipment such as helicopters， and the need for upgrades in key technologies. Therefore， this paper reviews the evolution of three key fish detection technologies：seabird radar， sonar， and echo-sounding buoys，across different target species. It details their current technical specifications and scientific applications， and examines the use of Unmanned Aerial Vehicles（UAVs）in tuna purseseine fisheries. Looking forward， we project a trend of deep integration between advanced hardware and artificial intelligence in next-generation detection systems. Guided by the principles of data-driven operation， intelligent synergy， and precision efficiency， we explore a future development path toward an integrated "sense-discriminate-decide" paradigm.
