One of the problems of developing seagrass beds by sowing was the incident that sediment movement washed the seeds away. Therefore, we suggested the method of developing seagrass beds by setting the lumps of mud that could weigh the seeds down and keep them under the sediment. We originated them and tried to prove the availabilities of them by the indoor and the field experiments. As a result, we could decide on the suitable materials, mixing ratio and sowing way for them andshow the validities of them.
