Research Abstract	Monitoring method for evaluating the impacts of bottom fishing practices to marine sessile organisms was developed by utilizing various data loggers (e.g. position, photo anddepth). These devices were installed in fishing boats that employ bottom trawl, longline and gillnet fishing gears. We demonstrated amounts of sessile organism bycatch by fishing sectors with important fishing parameters for considering the degree of impacts; bycatch per unit effort and bycatch per unit area.
