Abstract:
Water quality analysis is an essential aspect of aquatic environment studies to assess the pollution level and identify the suitable environment for fishery activities like fishing and cultivation. In this investigation, sample waters were obtained from five different sampling sites to evaluate the water quality status of the Naf river from March 2021 to September 2021. Throughout the research, seven physio-chemical parameters were analyzed, which were water temperature, transparency, turbidity, pH, DO, salinity, alkalinity and ranges from 27-34°C; 19-54 cm; 18-138 NTU; 7.2-8.2; 7-13 mg/L; 25-30 ppt and 86-336 ppm respectively. During the analysis among all sampling locations, no considerable variations were observed for any parameters, but significant differences were seen in the monthly data assessment, especially in April and July. The study revealed that the water of the Naf River is in good environmental condition for fisheries activity such as fishing and fisheries cultivation, comparing with the standard value of different water quality parameters.
