Sixty specimens of African sharptooth catfish Clarias gariepinus (Clariidae) were collected during the period of March 2014–February 2015 from boat landing sites and fishermen of the River Nile at Beni Suef Governorate, Egypt, and examined for the presence of digenean parasites. The morphology of these parasites was studied by using light microscopy to describe morphological and morphometrically measurements for different body parts. Three digenean species belonging to three different genera… 
Morphological and Molecular Characterization of Glossidium pedatum Looss, 1899 and Orientocreadium batrachoides Tubangui, 1931 from Sharptooth Catfish, Clarias gariepinus (Burchell, 1822)
The morphology and phylogenetic position of Glossidium pedatum and Orientocreadium batrachoides were determined for the first time and Phylogenies indicate that G. pedatum does not fit well into any known family within the Plagiorchioidea, as currently indicated in various systematic structures based on morphology.


New Records of Digenean Parasites of Clarias gariepinus (Pisces: Clariidae) from the Okavango Delta, Botswana, with Description of Thaparotrema botswanensis sp. n. (Plathelminthes: Trematoda)
Thirty-two specimens of African sharptooth catfish Clarias gariepinus (Clariidae) were collected from a number of localities in the Okavango Delta in Botswana and examined for digenean parasites, resulting in new geographical records for southern Africa.
Molecular characterization and new geographical record of Lecithochirium priacanthi (Digenea: Hemiuridae) infecting the moontail bullseye fish Priacanthus hamrur (Perciformes: Priacanthidae) from the Red Sea, Egypt
A preliminary genetic comparison between SSU rDNA of this parasite and other species of Hemiuridae places the present specimen as a putative sister taxon to Lecithochirium grandiporum and Lecitychirium caesionis.
Orientocreadium batrachoides Tubangui, 1931 (Orientocreadiidae): the only trematode parasite of Clarias gariepinus (Burchell, 1822) (Clariidae) from the Asi River (Southern Turkey).
It was detected that the specimens of O. batrachoides in Turkey are larger than previously reported samples, which is the first clearly documented report of the parasite in teleost fish of Turkey.
Prevalence and Intensity of Helminth Parasites of African Catfish Clarias gariepinus in Lake Manzala, Egypt
The relationship of host size and parasite infection showed that there was no significant difference in the parasitic infection among three classes, although fish of larger sizes had more infections, and the effect of fish age on the prevalence and intensity of gastrointestinal parasites is determined.
Interactions between the intestinal cestode Polyonchobothrium clarias (Pseudophyllidea: Ptychobothriidae) from the African sharptooth catfish Clarias gariepinus and heavy metal pollutants in an aquatic environment in Egypt
The hypothesis that cestodes of fish can be regarded as useful bioindicators when evaluating the environmental pollution of aquatic ecosystems by heavy metals is supported.
New Digenean Parasite Infecting the Freshwater Fish, Clarias gariepinus with Special Reference to its Tegumental Ultrastructure
It is found that, 12 out of 50 fish samples collected from Giza Province, Egypt, were found to be naturally infected with a new species (Pseudoholorchis clarii) that is named according to the host harboring this parasite which is distinguished from other species of the same genus by some interspecific variations.
A new record of Clinostomum philippinensis (Valasquez, 1959) in Trichogaster microlepis (Gunther, 1861) from Bung Borapet, Nakhon Sawan, Thailand.
An encysted metacercaria of Clinostomum philippinensis was found in the gills of Trichogaster microlepis, the second intermediate host of T. microlepsis, in Thailand and future work should investigate the epidemiology of the meetacercarial stage in the intermediate host and the adult in the experimental definitive host.
Study on Some Ectoparasitic Diseases of Catfish, Clarias gariepinus with their Control by Ginger, Zingiber officiale
The estimation of dissolved oxygen, pH and total ammonia of aquarium water pre and during treatment was indicated that the use of ginger in aquaculture operation will improve its water quality especially the total ammonia.
The Community of Parasites Infecting Clarias gariepinus in the Tanzanian Waters: A Case of Lake Victoria
Most parasites in Clarias gariepinus were highly overdispersed and the negative binomial model described their distribution.
