Aoriika, or bigfin reef squids, are seen spawning in the sea off Izu Peninsula, Shizuoka Prefecture. In April, a local fisheries cooperative submerged Japanese chinquapin branches for use as spawning beds about 13 meters underwater off Kawana, Ito City. One day in mid-May, about 20 pairs of the squids approached the beds. The female squids were seen laying white sacs of eggs one after another. According to a local diving service operator, spawning season will continue for about another month.
