The purpose of this research is to reveal and describe the quality of river waters and the fish comunity in Serayu river of Banyumas regency. The study was conducted using a survey method, with purposive random sampling technique. The study was conducted in Serayu river of Banyumas regency where three major rivers lead to it, namely Klawing river, Logawa river, and Tajum river. Fish sampled by spreaded net and handweb, with ten times sampling of each peripheral in each sampling point. Sampled fishes identified based on Kottelat et al. (1993) and verified on Biology Research Center, LIPI Cibinong and www.FishBase.org. Fish community structure analyzed by: Diverse, Cluster, and Multi Dimensional Scalling (MDS) of (Clarke and Warwick, 2001). The study found that water quality of physical and chemical parameters are in good condition. It includes temperature, flowrate, clarity, dissolved oxygen level, pH, and plankton species variation in Serayu River Banyumas Residency. Most species and individual number on Serayu River Banyumas Residency are from Cyprinidae Family. Species diversity are in low condition but there are no dominancies found. Fish abundance are higher in downstream area than in upstream area, but fish species diversity are lower in downstream area than in upstream area of Serayu River Banyumas Residency. Long period of mining activity could badly affect river fish’s life.
