The Rasian and Asahan rivers are located in the South Aceh District, Aceh Province, Indonesia, and are affected by the development of the cement industrial area and ports due to their proximity to the area. Therefore, this study aims to analyze and document the fish species diversity in the Rasian and Asahan Rivers as baseline and comparative data for the aquatic resource management plans and environmental impact monitoring programs, respectively. Sampling locations are determined purposively by dividing the river into upstream, midstream, and estuary. Furthermore, the fish was caught using gill nets and casting nets. The results show that a total of 16 species belonging to 12 families are obtained from the Rasian River. Meanwhile, 13 species belonging to 11 families were discovered in the Asahan River. These make a total of 24 species belonging to 18 families. One of the species recorded in the Asahan River is the alien fish (Trichogaster pectoralis). The diversity index in these two rivers falls within the moderate category, while the uniformity and dominant indices are in the high category. © 2025 The authors.
