The institute is located on the south coast
of Shikoku island and faces central Tosa Bay. The warm Kuroshio Current affects
the distribution of fauna and flora along the coast. The institute is built near
the fishery port of Usa at the mouth of Uranouchi inlet, which is about 12km
long and leads to the open sea through a shallow mouth at Tosa Bay. In the
inlet, fish and seaweed are cultured. The open sea and the inlet have sandy,
gravelly and rocky shores within their intertidal zone.
Bulletin of Marine Sciences and Fisheries, Kochi University have been issued once a year in Japanese and English.
Applications for use of the institute must
be submitted to the director in advance before your visit.
From Kochi city, the way to reach the institute is to take Kochiken Kotsu Bus from Sakaimachi to Sukairain Iriguchi, about one hours bus ride. From there, visitors are requested to cross the Usa Bridge, about 10 minutes walk.
