This study has been conducted with the intention of evaluating the recovery of the ecological system before and after the composition of the wetland in the regions of Lake Paro by analyzing the changes in fish with the use of site research after the composition of wetland, as well as the study of the ecological system data before composing wetland on the upstream of Lake Paro, as conducted in Yanggu-gun, Gangwon-do. This study also has the intention of being used as basic data for future management of the ecological system. The results of the research displayed 45 species of 12 families in the entire area of Lake Paro before composing the wetland. However, the region composed of wetland in the upstream of Lake Paro displayed a relatively weak number of fish with 22 species of 6 families. After the composition of wetland, 30 species of 7 families appeared and the group of fish in the wetland area is gradually stabilizing. The research within the wetland was found to have 62.4% of its entire biomass filled with an economic fish species, which equates to approximately 120 kg. This is a significantly large amount compared to the biomass generally found in other artificial lakes. Accordingly, this study is planning an improvement project in order to overcome the degeneration of water quality in certain regions in addition to the active assessment of plans which use the abundance of fish in the upstream of Lake Paro as a highly added value for tourism resource.
