Set at multiple points from the surface to seafloor, a system equipped with current velocity and dissolved oxygen sensors developed for remote monitoring on the seas was installed in a fish pen at Uchiura Bay, in Shizuoka Prefecture’s Numazu City, with the aim of monitoring the occurrence of hypoxia and elucidating the mechanism of fish mortality in fisheries. After analyzing the results, as well as analyzing the seafloor topography and sludge, it was found that the area directly under the fishery may be anoxic due to abnormal growth of microorganisms, resulting in the occurrence of death during stagnant tidal currents. Based on this, a system for preventing fish mortality was created, equipped with an alert function.
