The research was conducted from September 2020 to December 2020 using the field observation methods and purposive sampling techniques at three stations, data analysis employed comparative-descriptive. Parameters observed were abundance, diversity, dominance, uniformity, community structure and water quality. The results showed that 566 fish caught consisting of 8 species, 7 genera, 4 families. The fish community structure at stations 1, 2, and 3 was depressed, fish diversity at Cipeles river is low 0.86 < H^ < 0.89, with moderate dominance 0.55 < C < 0.62, low uniformy 0.16 < E < 0.17 suspected high influence of total suspended solids that have exceeded the waters threshold value for fisheries with concentrations between 67 mg/L-1 to 74 mg/L-1.
