Abstract

Bio-monitoring is considered to be a key process that enables biological indicators to survey the ecological healthiness of the habitat. The present study was conducted to assess the water quality by using biotic communities like algae which play an important role in aquatic ecosystems. This study was carried out for two years February 2018 to January 2020 in three different season’s viz. summer, monsoon and winter season to manuscript the diversity of algae and bio-monitoring purposes at Mamchari dam situated in district Karauli (Rajasthan). This lentic ecosystem is located in the local sub-basin of the Gambhir river basin near Village Mamchari, Keladevi road and approachable 15 km far from the city of Karauli in Karauli district toward the east of Rajasthan state of India. A total number of 42 algal species belonging to four different classes i.e. Chlorophyceae, Bacillariophyceae, Cyanophyceae and Euglenophyceae were reported from the two sampling sites studied. The class Chlorophyceae was dominated with 23 species (55%) followed by nine species of Bacillariophyceae (21%), eight species of Cyanophyceae (19%) and two species of Euglenophyceae (5%). The seasonal variation with respect to algal diversity was documented among summer (27 and 18 species), monsoon (9 and 8species) and winter season (19 and 19species) from the Site-I and Site-II, respectively. A total number of twelve pollution-tolerant genera such as Chlorella, Chlamidomonas, Closterium, Scenedesmus, Cyclotella, Synedra, Navicula, Nitzschia, Euglena, Phacus, Microcystis and Oscillatoria were reported. The Palmer Pollution Index 22, 4, 17 at Site-I and 8, 4, 8 at Site-II was calculated during summer, monsoon and winter season, respectively. This view discusses about the challenges in aquatic-bio monitoring of water system and provide an elementary vision into fresh water bio indicators and their role in assessment of water quality. This will be appropriate method for evaluation of ecosystem and important to quality control plan for aquatic systems.

Conclusion

In the present investigation, the study on the algal diversity of Mamchari dam, a freshwater dam, situated in Karauli district (Rajasthan) was explored for the first time. The investigation resulted in a total of forty-two species belonging to twenty-seven genera and four classes of freshwater algal flora was recognized during the study period. The study was conducted to explore the diversity of algae along with seasonal variation and bio-monitoring status of the study area. The seasonality studies shows that 25, 9, 19 species and 18, 8, 19 species were reported during summer, monsoon and winter season at Site-I and Site-II, respectively. A total number of twelve pollution-tolerant genera were reported from the study area. The Palmer Pollution Index 22, 4, 17 at Site-I and 8, 1, 8 at Site-II was calculated during summer, monsoon and winter season, respectively. Further, it indicates the study area was found high organic pollution during summer season, organic pollution during winter season and lack organic pollution in monsoon season at the Site-I. Besides, at the Site-II all three season found lack organic pollution. This increase of organic pollution is due to anthropogenic activities at Site-I. Thus, if water bodies are to be preserved for their intended use, one should protect their biota and maintain a sustainable and holistic approach to conserve such water systems. Scientists, environmentalists, local inhabitants and youth need joint efforts to protect water quality and biodiversity of this precious dam system. Regular monitoring of freshwater ecosystems, documentation of algal flora and study of their utility is encouraging area for future research. Effective methods to be adopt for Karauli founded on algal flora usefulness. Future scope of this study takes in the direction of: •Phytoremediation •Fish culture •Algal farming for food resource
