<![CDATA[Water quality analysis plays an important role in understanding the environmental factors that affect aquatic life, especially during critical periods such as fish spawning. The purpose of this study was to investigate several aspects related to water quality and its impact on hilsa fish species during their life cycle period. The study was conducted in Sungai Bilah over a four-month period in 2023, focusing on three specialized stations to assess water quality during the peak season of hilsa fish spawning. This study uses the descriptive method, with strategic sampling locations determined through interviews with fishermen. This method is crucial for understanding the impact of water quality on fish spawning activities. The results of the water quality analysis showed that each station had an average value of Temperature 26.625 °C, Turbidity 86.033, Total Suspended Solid (TSS) 88.75, Dissolved Oxygen (DO) 6.75, Nitrate 2.50, and Phosphate 0.002. Overall, these results indicate that the water quality in the observation area is in a condition that supports the successful spawning of hilsa fish, with stable temperature and adequate dissolved oxygen levels, while other parameters such as turbidity and TSS remain within acceptable limits]]>
