Evaluation of Pollution Status and Detection of the Reason for the Death of Fish in Chamo Lake, Ethiopia

Abstract: Chamo Lake is the third largest rift valley lake and one of the major economic sources for the communities in the Southern region, Ethiopia. The lake’s quality is deteriorating due to the untreated wastewater, and sediment inflow resulting in the death of fish was observed during the dry season. The research aims to determine the water quality status using water quality indices, in addition to identifying the reason for the death of fish in the dry season in Chamo Lake. The water samples were drawn from 5 samp… Show more

“…In this study, it has been proved by all of the respondents (100%) that the major problems of the lake were environmental contamination, water pollution, siltation, deforestation (shore damage), and over fishing, indicating a future threat for the lakes and its ecosystem. These findings are similar with different reports of Ethiopian lakes [50,[84][85][86][87]. The safety of food is affected by the health of animals, plants, and the environment within which it is produced [13].…”

“…The difference was significantly affected among age group and inspection of fish meat for the presence of parasites, as well as among educational status with respect to method of processing of fish meat before consumption (P ¼ 0:004 and P ¼ 0:002), respectively. The spread of food-borne parasitic diseases is enhanced by changes in human behavior, demographics, environment, climate, land use, and trade [13,55,84,85].…”

“…Wabe River is one of the rivers in the Gurage zone of southern Ethiopia flows across the urban areas and ends up into the Omo-Gibe basin. A number of anthropogenic and natural activities, including agricultural runoff water ( Ustaoğlu et al., 2021 ; Terfasa et al., 2019 ; Parris, 2011 ), domestic wastewater ( Preisner, 2020 ; Ustaoğlu and Tepe, 2019 ), dumping of solid waste in canals and inappropriate locations ( Menberu et al., 2021 ; Egbueri et al., 2021 ; Weldeyohanis et al., 2020 ), urban sediment inflow ( Egbueri, 2022 ; Sahle et al., 2019 ; Ustaoğlu and Tepe, 2019 ), river flows through lithogenic structures ( Asnake et al., 2021 ), and soil erosion ( Reddythota and Timotewos, 2022 ; Terfasa et al., 2019 ), have a negative impact on the water quality over time. These surface water resources are no longer suitable for drinking, industrial, agricultural, and other applications due to water quality degradation ( Egbueri et al., 2021 ; Ustaoğlu et al., 2020 ; Hamid et al., 2020 ; Şener et al., 2017 ).…”
