Keanekaragaman Ikan di Perairan Sungai Kampar Kiri Desa Mentulik Kecamatan Kampar Kiri Hilir Kabupaten Kampar Provinsi Riau

Abstract

The Kampar River is flown across the Mentulik Village and this area is inhabited by many fish species. This research aims to determine the diversity of fish species in the Kampar River, especially in the waters of Mentulik Village area. Samplings were carried out 4 times, once in 2 weeks, from October to November 2019. The fishes were captured using a gill net, fish hooks, scoop-nets, and fish traps. The fishes captured were then described and identified. Results showed that there were 211 ishes captured and they belonged to 24 species, 21 genera, 9 families, and 5 ordos. They consisted of Barbodes schwanenfeldii, Cyclocheilichthys apogon, Hampala macrolepidota, Osteochilus hasselti, O. kelabau, Oxygaster anomalura, Amblyrhynchichtys truncatus, Barbichthys laevis, Rasbora argyrotaenia, Botia hymenophysa, Thynnichthys thynnoides, Channa striata, C. lucius, Pristolepis grootii, Helostoma temminckii, Hemibagrus nemurus, Mystus nigriceps, Bagroides melapterus, Pangasius polyuranodon, Cygnolossus microlepis, Himantura signifier, Ompok hypothalamus, Kryptopterus lais, and K.limpok. The most common fish was M. nigriceps (12.32%), while the rarest fish were B. hymenophysa, C. microlepis, and H. signifier (0.47% each). The diversity index value (H’) was 4.1929 (high), the uniformity index value (E) was 0.9144 (medium) and the dominance index value (C) was 0.0643 (low). The number of species in the community is quite large because it is supported by a balanced environment or ecosystem and disturbances environment do not affect organisms. Water quality parameters were as follows: depth 4.53-8.15 m, transparency 22.5-30 cm, temperature 28-33^oC, current speed 0.38-0.46 m/s, pH 6, and dissolved oxygen 4.06-4.47 mg/L.
