Abstract

The present work aimed to investigate the prevalence of encysted metacercariae (EMC) in wild and cultured fresh water fish in El-Menia Governorate, Egypt. In addition, the effects of some processing methods on their viability were investigated. A total of 200 fish samples (100 wild and 100 cultured) included50 for each; Tilapianilotica (Oreochromisniloticus), catfish (Clariasgariepinus), bajad (Bagrusbajad) and carp fish (Cyprinuscarpio) were randomly collected from markets and some fish farms from El-menia city. Examination of encysted metacercariae (EMC) in the fish is commonly done by macroscopic examination and muscle compression technique.
