| Outline of Final Research Achievements |
Fish assemblage structures in planted seagrass habitats with mosaic structure (mixture of planted seagrass and open sand/mud areas) and with concavo-convex edge and also control planted seagrass habitats were investigated in a coastal area in southern Thailand. While total fish species numbers did not differ among these experimental quadrats, total fish densities tended to be slightly higher in planted seagrass habitats with concavo-convex edge and lower in the habitats with mosaic structure though the differences being not statistically significant. Density patterns of component species of the assemblages in the former were relatively similar to those in the controls, while some differences were recognized between the latter and others. Further studies and a continuous monitoring are evidently needed to clarify the effects of a various aspects of habitat structure including heterogeneity, edge structures and also other factors on seagrass fish assemblages.
