The Inland Sea of Japan is a place of formation «red tides». They are formed due to the active reproduction of dinophytic algae and their bloom. Algae accumulate in the surface layers of the water, causing its unusual shade. The toxins released by the algae enter the bodies of shellfish and fish. Such marine life becomes dangerous for humans and animals.. «Red tides» harm aquaculture and fisheries.
