ABSTRACT

This study aims to detect the change of marine aquaculture farm within the boundary ofHallyeo Marine National Park. Comparison has been made on the Landsat images taken in1984 and 2002 respectively by using feature extraction methods and other image analysistechniques. During the 18 year period between 1984 and 2002, total area of the aquaculturefarms has been decreased in 63 percent. The reason for the change seems to be that aquaculturefarms became concentrated only around the Geoje Islands due to the growth of the labor- andcapital-intensive cage aquaculture for the expensive fish species instead of traditional oysterfarming. Authors suggest the monitoring using remotely-sensed data as the best tool for themanagement of marine aquaculture farms on the basis of accuracy of analysis and relativelycheap cost. Management strategies of salmon farms in Tasmania, Australia has been analyzedto find the field techniques necessary for the management of aquaculture.
