Abstract

Assessment of Benthic Macro-invertebrate Communities in Relation to Water Quality in Teltele Stream, Ambo West Showa, Ethiopia

Highlights

Benthic macro-invertebrates can survive in different habitats such as at the bottom of rivers, lakes and reservoirs and they are correlated with different aspects of substrates like sediments, detritus, macrophytes and filamentous algae (Tesfay et al, 2017)
The study area, Teltele stream is found in Ambo town, which is located about 114 km West from Addis Ababa the capital city of Ethiopia
The physico-chemical of (DO) mg/L, S/cm, (Temperature) 0C, (TDS) m/L and NO3 etc water quality parameters of Teltele stream were given at the three sites (Table 1)

Summary

Introduction

Benthic macro-invertebrates can survive in different habitats such as at the bottom of rivers, lakes and reservoirs and they are correlated with different aspects of substrates like sediments, detritus, macrophytes and filamentous algae (Tesfay et al, 2017). Deforestation in the headwaters, erosion, siltation, domestic and industrial wastes, agricultural activities and diversions are the most important threats to degradation of surface water in general and streams and rivers in particular (Zinabu and Elias, 1989; Aschalew, 2015). These threats have numerous impacts including partial or total destruction of natural river biota, alterations to river functioning, over loading of self-cleansing mechanisms and associated drastic lowering of water quality. The main causes for contaminants of these water sources are agricultural activities, human excreta because of open field defecation practices, animal waste, and effluent from urban or industries (Aschalew and Moog, 2015; Mulugeta, 2010)
