In April 2003, seedlings ofEcklonia cava (plant length: 10 cm) were attached to two artificial reefs which had been placed on a breakwater at 4 m depth, off Usa in Tosa Bay, Japan. These transplanted fronds matured in October, and juvenile plants appeared around the reefs in February to March of the following year. Density and size ofE. cavawere measured at the bottom (1, 5, 10 m from the artificial reef) and lateral surface (2.5 and 3.5 m from the reef) of the breakwater by using a quadrat from April 2004 to February 2005. Density of 1, 5, 10 m was 36, 12, 4 ind./m2, respectively and 2.5 and 3.5 m was 104 and 56 ind./m2. Then density gradually decreased to February 2005 but half of the fronds which grew within 5 m from the reef survived. Many fronds ofE. cavamatured in October. In February, plant length and stipe length was 26.3-36.4 cm and 2.8-4.1 cm, and the density of juvenile plants was 32-172 ind./m2on average of quadrats. Thus a small but similar to naturalEckloniabed was formed around the artificial reefs.
