Abstract
Research morphometric characters of H. nemurus conducted in 2012 in the waters of Koto Panjang Reservoir Kampar Regency, the waters of Kampar River Langgam Village Kampar Regency and Kampar River Kampung Baru Village Pelalawan Regency Riau Province. The purpose of research is to analyze the morphometric characters, the main differentiating factor, determination of inter grouping of H. nemurus populations. Results showed that the average length of H. nemurus population standard Koto Panjang Reservoir Kampar Regency 281.33 ± 27.08 mm significantly different with populations Kampar river waters Langgam Village Kampar Regency 318.03 ± 32.07 mm and the water Kampar River Kampung Baru Village Pelalawan Regency 320.80 ± 32.03 mm. The main differentiator of 30 morphometric charac-ters are long dorsal truss2 (G2) and long dorsal truss3 (G3) with a value of 0.940 respectively. H. nemurus populations are geographically sepa-rated from each habitat and genetic distance H. nemurus populations in waters Langgam village closer with a population of Kampung Baru village.
