%X Demersal trawl sampling, representing 2 hydrographic seasons,were carried out in spring and autumn at stations distributed in the inshore waters of Guangdong Province.Ordinations of fish samples were derived,separately for the 2 hydrographic seasons, from multidimensional scsling of percentage dissimilarity matrices. The community patterns and their seasonal differences revealed by the ordinations are well correlated with the distributions and variations of the coastal and off shore water systems.In both seasons,fish assemblage.s are similar at most stations distributed in zones of mixed waters.The assemblages at other station groups differ distinctly from those of the most stations, respectively characterizing the Pearl River diluted water and the offshore saline water mass.The ordination of spring samples revealed a northeast-southwest difference of fish assemblages at most stations.This difference is caused by the invasion of the low temperature East China Sea coastal current in the northeastern part of the investigation area. Fish assemblages of autumn samples change along a salinity gradient from estuary, coastal,to offshore areas.The autumn community pattern is induced by the widespread of diluted water in the Pearl River estuary,and the invasion of off shore saline Water mass into the bottom layer of the outer edge of the investigation area. The community patterns in the Pearl River mouth are subjected to distributions and seasonal variations of river discharge, and changes of fish assemblages along salinity gradients are evident in both seasons.
