Benthic Macroinvertebrates of Five Small Lakes in Ciliwung Watershed and Estuary, Indonesia

Abstract Small lakes are biodiversity hotspots of freshwater ecosystems, home for fauna including benthic macroinvertebrates which play vital roles as it supports food sources higher-level organisms such fishes. This research aims to investigate the composition community in some small located Ciliwung watershed that surrounds Bogor, Depok, and Jakarta. Samples were undertaken on April June 2021 from four at watershed. They Telaga Warna, Situ Cikaret, Cincin urban lake, Sunter lake. Also includes an estuary lake ecosystem, Angke A total 22 taxa found, consist Mollusks (55.44%), Insects (6.27%), Annelids (38.29%). Mollusk was composed six families Gastropods one family Bivalves. Meanwhile, Diptera only Insect group. The abundance ranges between 101-4471 Ind/m 2 . pattern shows predominant group downstream area meanwhile most abundant groups upstream, middle, areas.
