Abstract: Three macrophytic species namely Ceratophyllum demersum, Hydrilla verticillata and Potamogeton lucens were investigated for the macroinvertebrate association in Manasbal Lake. A total of 15 macroinvertebrate taxa were reported from these macrophytic species belonging to three phyla including Annelida, Mollusca and Arthropoda. Arthropoda was the dominant phyla comprising of class Insecta, Crustacea and Arachinida. Annelida was the second dominant phyla represented by two classes Hirudinea and Oligochaeta. Mollusca were only represented by families, Lymnaeidae and Planorbidae. All the three phyla showed dominance pattern with respect to macrophytic species in the order of Ceratophyllum demersum followed by Hydrilla verticillata and then Potamogeton lucens. The results of study also showed that, the Ceratophyllum demersum comparatively harboured large density of macroinvertebrates than the other two macrophytic species, despite the fact that the total number of macroinvertebrate taxa remained the same on all the three macrophytic species thereby reflecting homogeneity of habitats. Among the insects, Chironomidae was dominant taxa on Ceratophyllum demersum followed by Hydrilla verticillata and then Potamogeton lucens.
