The benthic macro invertebrates can be used as a barometer of overall biodiversity in the aquatic ecosystem. In the productivity of lotic ecosystem, the importance of bottom fauna as a link in the energy flow from primary productivity to fish yield has been stressed by many workers. This paper describes the results of investigation of two lotic ecosystems on benthic macro invertebrates to determine the effects of increased nutrient concentrations from urban runoff inputs. The presence of indicator species like Chironomous larvae, Limnodrillus and Lymnia in abundance in river Zarpat indicate polluted status of the ecosystem. However, the absence or less abundance of indicator species in river Wardha indicates its less polluted nature. | | Keywords : | | |
