Considering the popularity of the scallop aquaculture industry and aquaculture operations with a net in Korea, Japan, and Southeast Asia, many problems exist as the management of fishing gear and alternation task are dependent on the traditional method which uses pure labor forces. Especially, it takes a lot of time and efforts for intra-coastal aquaculturing fishermen to remove hydras as well as green laver and shellfish that live in the low rise around the shore attached to the fishing gear, and such foreign matters as moss manually. For that reason, the fishermen had to avoid reusing fishing gear and buy new one resulting in environmental contamination and the increase of the fishery cost. Because of the eco-friendly issue, aggravating management cos, and the decreasing catch of this management system, the need for development of cleaning equipment of fishing gear has been required consistently. Therefore, for development of cleaning equipment of scallop fishing gear this study aims at implementing a test which searches for the best condition for improvement of cleaning efficiency and finding optimization of cleaning variables.
