Sampling was carried out at 3 observation stations, namely the upstream, middle, and downstream parts of the river. The aim is to show the value of sommunity structures such as index of fish diversities, the similarities, dominances, native and aliens species. The number of fish species that have been identified as many as 8 species, there are 7 native fish, namely: Bilis (Anchoviclla commersoni), Lais (Cyptopterus micronema), Seluang (Rasbora Sp.), Tengadak (Barbonymus schwanenfeldi), Hampala (Hampala macroleptitoda), Tilan (Barbonymus schwanenfeldi), Baung (Mystus) and 1 type of invasive fish, namely Toman fish (Chana Pleurophthalma) Diversity Index Value (H') 1.85861622. The value of the Diversity Index in the waters of the Mengkiang River is included in the medium group, namely moderate distribution and moderate community stability. Stable community that is high similarities Index Value. The Dominance Index value of the Mengkiang River is included in the low criteria. The condition of the waters of the Mengkiang River is still in good and well-maintained condition.
