Survival and Growth of Sea Grasses Transplanted under Artificial Conditions

Comparative survival and growth of turtle grass (Thalassia testudinum König) and shoal grass (Diplanthera wrightii Ascherson) transplanted in aquariums and through-flow sea-water tanks were observed. In aquariums, turtle grass survived 7 months and shoal grass 3½ months. In tanks, turtle grass lived through an experimental period of 12 months and produced new leaves, roots, and rhizomes, but only a few shoal grass plants survived.
