Boat Liftnet gear is a fishing gear that requires special attention in the biological, economic, technological and social aspects. Therefore proper management is needed in the development of a liftnet fishery business. This study aims to identify the composition of the boat liftnet catches, identify the level of catch and discard, determine the arrival patterns of fish primarily by catch and discard fish, and provide information on underwater fish lamp design that is expected to reduce the catches by catch and discard. The study was conducted in Mekar Village, Konawe Regency, Southeast Sulawesi Province. In May - July 2019. The research method used was through experimental fishing. The results showed that the boat liftnet is less environmentally friendly, the pattern of arrival of fish in the area around the light source consists of solitary and clustered, there is a pattern of fish behavior as a form of adaptation to light where the fish will stay away after about 40 minutes around the lamp, the device design is needed underwater dip lights are enhanced with the addition of several other supporting devices such as CCTV cameras and monitor screens, hereinafter referred to as UFL + ( Underwater Fish Lamp Plus ) with the aim of streamlining the capture time and reducing the number of by catch and discard.
