Assessment of Physicochemical and Microbial Factors of Water in Lower Anaicut Basin, Tamil Nadu, India

Water quality and quantity have an important impact in a region's health, wealth, and prosperity. Water pollution is a phenomenon that occurs when the quality of water deteriorates as a result of numerous human activities. This chapter provides basic idea of physiochemical and microbial factors which gives sustainable environment for aquatic life. In this chapter, the physico-chemical parameters and microbial population in soil sediment, water and gill region of Labeo rohita from Lower Anaicut Basin were examined. Based on their growth characteristics on specific culture media, some human bacterial and fungal pathogens were isolated. The fishes' medium and the sediments in their habitat were also collected and tested for pathogens. In the gill region, however, five bacterium species and four fungus species were discovered.This study focuses on the quality of Labeo rohita in the Lower Anaicut basin and aims to raise awareness among fish consumers.
