First Report of Lernaea cyprinacea (Copepoda: Lernaeidae) on Rainbow trout (Oncorhynchus mykiss) from the Sarı Mehmet Dam Lake in Van-Turkey

DOI: 10.26650/EuroJBiol.2018.398174Objective: This report focuses on the diagnosis of rainbow trout mortality in the Sarı Mehmet Dam Lake.Material and Methods: The ten rainbow trout (Oncorhynchus mykiss) (300 - 350 g) examined were infested with numerous copepod parasites which were attached to body muscles especially in the caudal and abdominal area.Results: According to morphological results, this parasite was identified as L. cyprinacea. Histopathological examination of lesions revealed inflammatory response in the dermis and skeletal muscles and infectious granuloma.Conclusion: This paper is the first to describe cases of lernaeosis on the rainbow trout (O. mykiss) from the Sarı Mehmet Dam Lake in Van-Turkey.
