Abstract
As for the scallop farming in Mutsu Bay, the scallops are cultivated in longline method cultured
facilities. It is necessary to install a buoy to keep cultured facilities at the most suitable depth with the
growth of the scallop. It is necessary for the fisherman to check a subsidence state of facilities every day.
In addition, it is necessary much labor and expenses because the fisherman owns plural cultured facilities
in the large sea area. Therefore, we built the system that remoteness watched depth and the water
temperature of scallop cultured facilities with an ultrasonic telemetry system and a mobile phone
network that we largely improved efficiency of the fishery work and improved productivity. The
fisherman can confirm the situation of facilities at an information terminal by almost displaying a
monitoring result in Web in real time. Furthermore, as for the system installed in the cultured facilities,
9-month continuation operation was confirmed in a proof examination to minimize the burden on
fisherman.
