Abstract:
Cijalu River is located in Western Cilacap Regency Central Java . The river of Province runs through forestry,
housing and farming areas. This condition leads to a prediction that the river has been altered on its physico-chemical
characteristics causing the river to be inhabited by a variety of fish species. This study aimed to collect data about fish
species inhabiting Cijalu River and its distribution. A survey method has been done with clustered random sampling
technique. The river was divided into three different areas, i.e. upper-,middle- and downstreams. Species diversitywas
measured as the number of species, while distribution was measured as the presentation of fish species in each site.
Nineteen fish species of 10 families were identified from Cijalu River. The 10 families were Anabantidae, Bagridae,
Balitoridae, Channidae, Cichlidae, Cyprinidae, Loricariidae,Osphronemidae, Poecilidae and Sisoridae. Cyprinidae was
the family having the highest number of species (6 species), followed by Bagridae (3 species), Channidae (2 species)
and Osphronemidae (2 species). The remaining respective families were represented by one species. A complex
pattern of fish distribution was observed during the study. Glyptothorax platypogon and Channa gacua were only found at
the upper-streams, while Anabas testudineus was obtained in downstreams. The other remaining species could be
observed either fromthemiddle- to downstreams, or even fromupper- to downstreams.Different pattern of species
distribution could be caused by physico-chemical characteristics variation from upper to lower parts of the river,
especiallywater velocity and substrate types.
