| A new method of transplanting seagrass is proposed. This method has the advantage of requiring no sowing seed and no planting roots while conventional planting methods require sowing or planting. The method developed in this study consists of two steps for completing seagrass transplanting: to place mats on the seabed near seagrass field so that seagrass seed fall on the mats and germinate naturally, and to replace the mats on which seagrass grows to the place where seagrass is to be planted. A field study for validating the method has been carried out at Ago Bay, Mie prefecture. More than 1000 shoots/m2 could be germinated on the mats without sowing and planting. The rate of seagrass growing on the mats, however, was slower than those at the natural seagrass field after replacing the mats. The reason might be the roots were damaged during the replacing process. |
