Mystus vittatus, Nandus nandus, Anabas testidunieus, T. fasciatus, Botia derio, Notopterus notopterus, Monopterus cuchia etc. for having high overseas demand have potential value as food and ornamental. 26 different spp. of phytoplankton belonging 4 classes were recorded. 10 species under chlorophyceae, 6 species from cyanophyceae. 8 species under bacillariophyceae and euglenophyceae contains 2 species.
