Studies on the Spring Marine Algal Flora of Hongdo, Southwestern Coast of Korea

As a part of ocean ecological primary investigation for the conservation of the Hongdo coastal ecosystem with respect to culture areas and fish grounds, marine algal communities were investigated marine algal species, relative coverage, relative frequency, dominant ratio and standing crops. southwestern coast of Korea. In this observations, 43 species in total, 6 green algae, 16 brown algae and 21 red algae were indentified. The representative dominant species were as follows; Gloiopeltis furcata, Myelophycus simplex in upper tidal, Enteromorpha linza, Ulva Pertusa, Sargassum thunbergii in middle tidal, and Hizikia fusiforme in lower tidal zone. Sargassum of forming aquatic forest were dominated by Myagropsis myagroides, Sargassum serratifolium and Sargassum trotile. The relationships between the total length, wet weight and dry weight of Myagoropsis myagroides were as follows: WW = 55.4498 TL0.4946, r =0.8735 WW = 169.7890 + 5.1148 DM, r=0.9938
