Title: Survey of Helminthes Parasite of Four Fish Species in Al-Dinder and Al- Rahad River
Author: Salih, Reem Rabie Mohammed; Hamid, Samia Hamid Ahmed; Ahmed, Fawzi Ali Mohamed
Abstract: This study tends to survey of helminthes parasites at Maya of Dinder National Park and Abraham dam at RAHAD River. Five fresh water fish species, Heterotis niloticus, Bagrus bagrus, Clarias lazera and Oreochromis niloticus from Al-Dinder River at Sennar State and also in other location, the same species were taken addition to Lates niloticus from Al-Rahad River, Abraham dam at Algadarif state. The prevalence rate and density of parasites were recorded. The result of this study included first macro-microscopic by examination of parasites as identified by Paperna (1996) and these were: One species of cestodes: Polyonchobthum polypten in Clarias lazera from Al-Dinder River (Mayah Altomsah). Two species of nematodes: Procamallarus laeviconchus, Cucullanus barbi in Oreochromis niloticus and Clarias lazera from ElRahd River (Abraham dam). Four species of trematodes: Clinostomum cutaneum, prgidiosis metacercaria in Clarais sp. and Oreochromis niloticus, Bolbophorus levantinus, early metacercariae, Clinostomum tilapia in Oreochromis niloticus, Heterophyes heterophyes in Oreochromis niloticus from Al-Rahad River (Abraham dam). The presence of these parasites in fish did not manifest any apparent legions, necrosis or pressure atrophy in visceral organs. However, the most string finding was the presence of identified metacercarial cysts in the Oreochromis niloticus and Clarias lazera from Al-Rahad River. Even the specimens examined for Clarias lazera from Al-Rahad River (Abraham dam) were found as encysted metacercaria. The further studies were suggested to investigate the health status of fish in both locations throughout various seasons
