Struktur Komunitas Ikan Di Perairan Sungai Indragiri Desa Lubuk Terentang Kecamatan Gunung Toar Kabupaten Kuantan Singingi Provinsi Riau
Indragiri River has high fishery potential. Fishing activities conducted however, affect fish population in general. A research aims to determine the community structure of fish in that waters was conducted in 16-21 August 2018. Fish was sampled every day for 15 days. The fish was captured using gill net, nets and fishing rods. Data analyzed were diversity index (H'), uniformity index (E) and dominance index (E). There were 21 types of fish captured, they were belonged to 9 families, namely Cyprinidae, Belontidae, Osphronemidae, Siluridae, Bagridae, Loricarinae, Helostomatidae, Pangasidae and Mastecemlidae. Diversity index (H') 2.797, uniformity index (E) 1.179, and dominance index (C) 0.315. Temperatures was 28-29, brightness 25-28 cm, depth 3.8m, pH 6, dissolved oxygen 5.3-5.4 mg/l and free carbon dioxide 4-4.2 mg/l. Data obtained indicate that community structures of fish in the Indragiri River was relatively good and there was no dominant species.
