As a first step in obtaining the minimum level of data needed to develop smart cultivation technology for Korean seaweed gim (Pyropia yezoensis), farming tests have been carried out using onshore aquaculture facilities. The aquaculture facility was built on paddy farmland on the west coast of Chungnam and received seawater from nearby sea. In this paper, we report the overall process and results of the aquaculture trials attempted in Korea's first onshore gim aquaculture facilities. In addition, the industrial possibility of gim production using the onshore aquaculture system will be discussed through the analysis of all expenses incurred in the test form.
