Informationization has become one of the essential emerging technologies,which supports the innovation and sustainable development of modern fishery. In order to promote the application level in aquaculture, the knowledge mining technology, parameter identification and organization forms of perception network, research status of acqusition and monitoring for information of regional water environment, and change of breeding area and its spatial and temporal characteristics were summarised according to the attributes and scale of the information,the flow of farming activities and the hierarchy of modeling and applications. And models of prediciton and early warning of water quality, methodologies of knowledge representation and inference in aquatic desease diagnosis, quantitative and analytic methods of aquatic products’ behaviors, establishments of nutrition formula and feeding decisionmaking system, perception contents and constructions of platform in traceability, and control strategies and methods in aquaculture system were analyzed and compared by systematically summarising and clarifing the literature. The results indicated that the aquaculture industry has been penetrated profoundly by information technologies for comprehensive perception and decision support; the information acquisiton has been transformed from artificial to digital intelligence, such as perception networks and remote sensing; information processing was developing towards the process of modeling: the expert systems, management systems, decision support systems, traceability systems and precision control systems, which were based on artificial intelligence, information fusion and intelligent information system; and the applications of information has also paid more attention to mutual adaptation, promotion and optimization between the thoughts of information and management and aquacultures’ operational efficiency and benefits.
