  1. Transplant or seed organisms onto subtidal artificial structures

    A study in 2003–2005 on a subtidal breakwater on open coastline in Tosa Bay, Japan (Serisawa et al. 2007) reported that kelp Ecklonia cava transplanted onto concrete blocks placed on the breakwater grew and appeared to reproduce. Over 22 months, transplanted kelp grew to reproductive size (data not reported) and new recruits appeared on the surrounding breakwater surfaces. After 22 months, there were 0–53 kelp recruits/m2 within 10 m of the transplants, depending on the distance from transplants and the orientation of the surface (data reported from Figure 4 in original paper). Recruits grew to 260–360 mm length. Kelp seedlings (100 mm length) were attached to ropes fixed on two concrete blocks and transplanted onto a concrete breakwater at 4 m depth in April 2003. Other details were reported in Japanese. Transplanted kelp were monitored and new recruits were counted on breakwater surfaces over 22 months.
