Intelligent monitoring and control technologies of open sea cage culture: A review

摘要

Since open sea cage culture sites are far from shore, the sea situation is complex and changeable, and the monitoring of cage culture water quality, fish behaviour, cage operation and other states is the basis of intelligent control of cage casting, feeding, capture, and cage washing to achieve high yield, high efficiency, and safety of cage farming. First, a cage farming model is introduced for analysis of the needs of intelligent monitoring and control technology. The applications of underwater robots, unmanned aerial vehicles, online monitoring networks and other technologies involved in aquaculture water environment information monitoring are summarized. Secondly, the intelligent management of cages is summarized. This paper demonstrates that cage farming is the trend of aquaculture. In the future, applications will combine information monitoring technology, intelligent control technology, and intelligent equipment technology to realize intelligent, digital, automatic and unmanned operation of cage aquaculture.
