Abstract
The technique of measuring oceanic temperature and current by fishing boats has the potential to allow monitoring of wide coastal sea areas ; fishing boats allow the observation of oceanic conditions by using fine spatial-temporal measurement scales under water in coastal areas. We introduce an operational delivery system for daily mapping of sea surface oceanic conditions in Hyuga-nada measured using information from fishing boats. We discuss the factors that contribute to the stable operation of temperature and current measurements by fishing boats. The technique may be implemented without burdening fishermen and has
low initial operational and maintenance costs. This technique could be expanded to other sea areas if the feedback system is widely taken up by fishermen. However, it will be important to clarify the intended purpose of the data to fisheries in each sea area.
