Assessment of physical health characteristics in selected Selangor rivers in Malaysia
This research aims to evaluate the physical habitat quality of the Rawang sub-basin of the Selangor River. Seven river sampling sites were selected, including Guntong (SR1), Guntong’s tributaries (SR2/reference), Kuang (SR3 and SR7), Gong (SR4), Buaya (SR5), and Serendah (SR6) using random sampli...

| Summary: | This research aims to evaluate the physical habitat quality of the Rawang sub-basin of the Selangor
River. Seven river sampling sites were selected, including Guntong (SR1), Guntong’s tributaries
(SR2/reference), Kuang (SR3 and SR7), Gong (SR4), Buaya (SR5), and Serendah (SR6) using random
sampling techniques based on accessibility and proximity to freshwater fish farms. The habitat assessment
was performed during the rainy and dry seasons in August 2019 and December 2019, respectively. Results
indicated that the Guntong River tributary (reference site) recorded the highest Qualitative Habitat Evaluation
Index (QHEI) (14.99) compared to the other locations under the suboptimal condition (11 – 15.9). The
average habitat score of other sampling sites under the suboptimal condition, namely Guntong (SR1), Kuang
(SR3), Buaya (SR5), and Serendah (SR6) Rivers, were recorded as 13.16, 11.30, 12.58, and 14.05,
respectively. Meanwhile, the Kuang River (SR7) score was 10.65 under the marginal condition (6 – 10.9).
This study’s lowest average habitat score was the Gong River (SR4) under marginal conditions (10.61). To
conclude, this study showed that the QHEI is a helpful tool in identifying the potentially unsustainable fish
farming impacted river sites to evaluate the river’s physical health. |
