Parasite Communities of Oreochromis niloticus baringoensis (Trewavas, 1983) in Relation to Selected Water Quality Parameters in the Springs of Lorwai Swamp and Lake Baringo, Kenya. Acta Parasit. 65, 441–451 (2020). https://doi.org/10.2478/s11686-020-00178-2https://doi.org/10.2478/s11686-020-00178-2https://repository.nrf.go.ke/handle/123456789/676PurposeParasite infections may lead to mortalities in fish; therefore, destabilizing the biodiversity and ecosystem functions. Swamps such as the Lorwai Swamp are important water sources, and information on the parasite species infecting Oreochromis nilotocus baringoensis in the hot springs of Lorwai Swamp which have a distinct genetic makeup from their counterparts in Lake Baringo is lacking. The purpose of this study was to provide a knowledge base on the parasite species infecting O. niloticus baringoensis in these springs, facilitate their comparison with those in Lake Baringo and determine their relationship with selected water quality parameters.Methods347 fish were collected and standard parasitological procedures were used to examine the presence of parasites. Physico-chemical parameters were measured in situ and water samples were collected for chlorophyll-a determination and nutrient analyses in the laboratory using standard methods. Relationship between parasitic infections and selected water quality parameters was determined by PCA using SPSS version 22.ResultsTwo parasite species were common in all sites: Cichlidogyrus sclerosus and Clinostomum sp. Some parasites correlated positively with some parameters; Amirthalingamia macracantha and Contracaecum sp. with nitrogen compounds. Others like Clinostomum sp. and Tylodelphys sp. correlated negatively with dissolved oxygen.ConclusionResults from this study showed that there were both positive and negative relationships between some water quality parameters and the prevalence of recovered parasites. O. niloticus baringoensis from Lake Baringo also recorded high parasite prevalence and this calls for sensitization of the public on the risks that may arise from the consumption of undercooked infected fish.enEgerton UniversityArticle
