Highest abundance values were recorded for Pleurosigma spp. in March (43,200/100 liter). Various diversity indices including Shannon's diversity index, Simpson's diversity index, Margalefs richness index and Pielou's index were calculated. Hierarchical clustering and N - MDS ordination from Bray-Curtis similarity matrix of plankton group abundance data show maximum similarity between Cosctnodiscus spp. and Pleurosigma spp. indicating co-occurrence in the coastal water. Shepard's diagram indicated highly stressed condition of this ecosystem. 收起
