Koliyak is located on the coast of Bhavnagar. It is included in the Gulf of Khambhat. The quality of water is important for living marine organisms. In the present study, we carried out a study of the Physico-chemical parameters such as Dissolved oxygen, Total Dissolved Solids, pH, Conductivity, Temperature, Resistance, and Salinity. In physicochemical among selected parameters level of turbidity was high found. The main purpose of this study to determine the present water quality at koliyak coast.
