| 内容記述 | Early growth and mortality of the autumnal-fruiting type of Sargassum horneri were surveyed at Ohno-seto strait, Hiroshima Bay. Embryos were planted on artificial substrata in Decenber 1994 and were placed at two stations in the area: St. 1 without natural individuals, and St. 2 with dense distribution of S. horneri. The growth of germlings on the substrata was slow during the winter and early spring at both stations. Rapid increase of thallus length occured at St. 2 as water temperature rose after May, but growth at St. 1 was greatly inhibited due to the accumulation of fine sediments on the thalli in summer. The mortality was high during the first month after setting the substrata and also from June to September, and relatively low from February to May. Although the survival curves were similar, the ecological and physiological features of germlings were quitely different at the two stations. Germlings at St. 1 were covered with fine sediments and discolored, and germlings at St. 2 were damaged by abrasive effects of sand sediments during winter and from amphipod nesting activities in spring. Among these, the sedimentation might be the most important factor which affects the settlement, growth and consequently the distribution of S. horneri in this area. | |||||
