Abstract: The River Indus is one of the most extended water bodies in Pakistan. It is a source of drinking water, hydroelectric power generation, irrigation, agriculture and aquaculture. The present examination wanted to survey the river's physicochemical parameters and biodiversity from June 2016 to May 2017. Total eight stations have been selected along the Indus River, and 08 water quality parameters, i.e., temperature, salinity, dissolved oxygen, power of hydrogen, transparency, alkalinity, hardness, and total dissolved solids, have been checked from all stations on the spot and bring water samples in a plastic bottle. Fish samples were also collected from all stations, preserved all the samples in 10% formalin, and further investigated in the Fresh Water Biology Laboratory at the University of Sindh Jamshoro. A total of 45 fish species have been identified throughout the study period.

Keywords: biodiversity; water quality parameters; Indus River.
