Research Abstract

Megabalanus rosa, a common barnacle in shallow waters in Japan, has been tested to be a key species to form subtidal biological communities on the quay wall in Okkirai Bay, northern Japan. As a results, it enhanced settlement of macro-algae during winter season when water temperature in winter being even or higher than average year, but not on a year with lower temperature. It also enhanced higher biodiversity on the test plates due its greater area and surface contour formed by its shells. But the barnacle did not survive until next year in this experiments. Strongylocentrotus nudus, a common seaurchin in this area, had significant effects on biological communities of test plates like a rocky-shore denudation. This species showed up-and-down feeding activity, and fed 0.53g (dry weight) a day at 15℃ in maximum. Elimination or cull for this seaurchin seemed to be indispensable to form or recover biological communities in the subtidal zone in this area.
