The purpose of this study is the improvement of a hook for the collection of marine wastes on the seabed, which is connected to the spring device. The performance of the modified hook was tested on the seabed around Wando island. The collection efficiency of the hook was improved especially in the rocky area on the seabed. A experiment in the study area is verified with seafloor images displayed by Side Scan Sonar. The modified hook can be used for the collection of marine wastes with the its less frequent loss in the sea.
