Abstract

A study of helminth parasites of Clarias lazera in Assiut city, Egypt was carried out. A total of 50 Clarias lazera were collected live from Nile River at Assiut city, Egypt in the period between April 2014 to April 2015. Adult flukes were obtained from Albino rats experimentally infected with the metacercariae at day 7 post-infection. Overall prevalence of infection was 92%.The highest incidence percentage of encysted metacercariae in examined Clarias lazera fishes was detected in the posterior region (93.47%), moderate distribution was detected in the middle part with a percentage of 71.73% while the lowest distribution was recorded in the anterior part (43.7%); these data were found statistically significant (p level<0.01). The prevalence of encysted metacercariae (EMC) was higher during Summer (81.8%), followed by Spring (78.1%), Autumn (60%) and Winter (53.4%). In Conclusion, 92% of examined C. lazera fishes were infested with EMC.
