Characteristics A separate window opensReferences

These are the deep waters of the Hoyo Strait. These waters are an important spawning grounds of the Japanese jack mackerel and Pacific cutlassfish, important fisheries resources in the region, and other species. Since the Hoyo Strait is narrow at 14 km wide and both sides of the strait are steeply inclined, it forms a diverse maritime environment (in terms of water temperature, ocean currents, salinity, and nutrient salt) through the fierce churning of waters from the Seto Inland Sea with those from the open sea coming through the Bungo Channel (Sanada, 2008).
