This investigation deals with the effect of paper mill effluent, on the histochemical components of the liver of Rasbora daniconius. The Paper mill effluent was collected directly from the 45 Km away from Aurangabad (MS) India. Histochemical studies on protein, lipid and glycogen contents of liver Rasbora daniconius showed a progressive decrease in staining intensity to Mercury bromophenol blue (Hg-BPB), Sudan black B and Bets's Carmine at 30 days exposure when treated at sublethal concentrations (1.9% and 0.95%) of paper mill effluent. The magnitudes of these changes were dose dependent. This study, therefore, concludes that paper mill effluent creates metabolic crisis and impairment in fish liver. The depletion in level of protein, lipid and glycogen points towards exhaustion of cell-energy to meet high demand of fish in stressful condition.

The present study deals with the survey of helminth parasites from Aurangabad city (M. S.) India, during 2015 to June 2016. This report summarizes the data of incidence, intensity and density of infection of helminth parasites in freshwater fishes in relation to environmental factors. Fish samples were collected from Godavari River, Paithan, Aurangabad, examined for helminth parasites. During the present study 100 fishes were examined

An avifaunal survey was conducted at Majalgaon Reservoir for two years, starting from July 2016 to June 2018. The study reveals a rich avian diversity a total of 84 species of birds belonging to 15 orders and 30 families were identified. As the water of the wetland is clear, rich in dissolved oxygen and supports variety of aquatic weeds and fishes, it has been found to be suitable for birds and attracts many migratory birds like large egert, purple heron, white bellied heron, asian open bill stork, greater flamingo, white naked stork etc. Continuous monitoring on the avifaunal diversity was suggested to evaluate the ecological status of the habitats and birds. It can be considered as an efficient tool to the environmentalists, policy makers in order to conserve such species, because, the role of birds in an ecosystem cannot be ignored.
