Industrial revolution 4.0 is a transition from manual process to automation processes were based on computer technology capabilities. Technological development towards the use of the Internet of Things (IoT) and Big Data must begin with the digitization process in all sector, including fisheries and aquaculture. Digitization in fisheries has brought many changes to the process of cultivation and catching fish. Time, cost, and labor efficiency are the main advantages of digitizing fisheries. The purpose of this paper is to determine the extent to which the digitization in fisheries, especially aquaculture, the method used in this paper is systematic literature review. The process of digitizing aquaculture can be seen from various aspects, including pre-production aspects (determination of cultivation locations using GIS), production aspects (using automatic feeders and automatic water quality testing tools can improve resource efficiency), and post-production aspects (utilization of digital marketing).
