Macrozoobentos Distribution as a Bioindicator of Water Quality in the Upstream of the Citarum River

Abstract

This study aims to prove the type and abundance of macrozoobenthos are affected by the physico-chemical condition of the habitat so that it can be used as a bioindicator in assessing river water quality with a case study in the Upstream of Citarum River. The method used in this study consists of two stages, namely determining the status of river quality with pollution index and determining the components to see the relationship of the water quality parameters to the abundance of macrozoobenthos with principal component analysis. On the basis of these studies, the results were that at the location of the study status of the river quality is slightly polluted and mildly polluted. For the slightly polluted status Corbicula sp. was used as the dominant macrozoobenthos parameter with the parameters of dissolved oxygen, organic carbon and N-O in the clay-dominated sediments. In turn, for the river areas with mild pollution, Enallagma sp., Tubifex sp., and Chironomous sp. were used as bioindicators and they have a relationship with the parameters of nitrate, TSS, and P-total.

Macrophyte- and Macrozoobenthic-Based Assessment in Rivers: Specificity of the Response to Combined Physico-Chemical Stressors

“…The biotic index (BI) includes two metrics: the total number of taxa and taxa richness of indicator groups A (very sensitive), B, C, D, and E (very tolerant). The individuals were counted, and the abundance was divided into five abundance classes: few (1-5), present (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20), common (21-50), plentiful (51-100), and dominant (100+). The values of the BI depend on the relative proportions of the tolerance groups.…”

“…Consideration of two groups of organisms enables more comprehensive and reliable monitoring than an assessment based on a single group, especially where the standard bio-indicative practices can be distorted by extreme local conditions [2]. Macrophytes and macrozoobenthos have a close relationship with key physical and chemical parameters, revealing that environmental conditions have a major influence on the type and continuity of macrozoobenthos [11] and macrophytes [6].…”

A global synthesis of ecosystem services provided and disrupted by freshwater bivalve molluscs

“…those produced by phytoplankton (Wood et al ., 2006; Lepoutre et al ., 2020 b )], and human pathogens and diseases, such as microsporidia (Lucy et al ., 2008), Escherichia coli (Selegean et al ., 2001), and other bacteria (Graczyk et al ., 2001) and protozoa (Géba et al ., 2020 a ). Other, more scarcely applied indicators used in FB biomonitoring of water quality include simple presence/absence of (indicator) species (Chazanah et al ., 2020), morphological condition indices, including growth rates (Cataldo et al ., 2001 a ; Thitiphuree et al ., 2013), and Na:Cl ratios in shells as indicator of road salt pollution (O'Neil & Gillikin, 2014). In some cases, long‐term monitoring programs utilising one or more of the indicators described above (e.g.…”

Community structure and diversity of benthic macroinvertebrates as bioindicators of water quality in some waterfall ecosystems, Bawean Island, Indonesia

“…Water quality monitoring using physicochemical and biological methods was developed as a complementary mitigation step (Setyono and Himawan 2018). Physicochemical parameters can be used to measure water quality while biological methods describe the effects of several environmental changes in the short and long term (Retnaningdyah et al 2017;Retnaningdyah and Arisoesilaningsih 2019b;Chazanah et al 2020). The use of benthic macroinvertebrates as one of the bioindicators and biological methods is based on its response to vary of environmental variables.…”
