The aim of the present study was to determine whether large sporophytes originating from Nabeta Bay would turn into small sporophytes with short stipes when transplanted to Nakagi Bay.
Cause Of Decline:
Ecklonia cava is a large perennial kelp and forms a dense forest along the coast from central to southern Japan. The kelp forest plays an important role as nursery and breeding space for commercial fish, shellfish and other animals, and has high productivity. Recently, it has been reported that marine plant communities, including kelp forests, have disappeared or diminished along the Japanese coast. As an extreme example, 180 ha of E. cava forest disappeared in Tosa Bay, resulting in a collapse of the abalone fishery.
