The method used in this research is a case study method with four stations. Data analysis using a Diversity Index (H '), Dominance Index (C) and Equitability Index (E) and the data of fish abundance were also obtained. Results shown that there were four families, six genera of fish that were consisted of 8 species, namely: : Clarias batrachus, Channa striata, C.micropeltes, Trichogaster pectoralis, T. leeri, Anabas testudinus, Helostoma temminckii, Pristolepis grooti. The fish abundance relative ranged from 27,92% - 0,19% ind/genus; H’ 2,7011 – 2,2191; C 0,2616 – 0,1681 ; E’ 0,7343-0.6033; temperatures 29,7 – 30,3 ⁰C; Depth 184,7 – 235,7 m; transparancy 32,5 – 56 cm ; turbidity 5 – 5,7 NTU; pH 4,7; dissolved oxygen 2,07 – 3,3 mg/l. Parameters water quality like a depth, pH and dissolved oxygen giving direct impact between fish abundance in the wetland area of Rantau Baru Village.otherWater qualityfish communitiesWetlandRantau Baru Villagestudent Paper Post Degree
