Abstract

The Ecklonia kurome population off Gounoura, Iki Island, northern Kyushu was heavily grazed by herbivorous fish in autumn 2013 and the frond of E. kurome had been removed partially or completely. From December 2013 to March 2014, we monitored frond regeneration of tagged E. kurome. Most of E. kurome with blade primordia formed secondary laminae along both sides of the primary lamina, becoming the same morphology as that before they were grazed. More than half the number of E. kurome stipes, for which the entire frond including blade primordia had been removed, also regenerated a frond.
