Prevalence and Intensity of Helminth Parasites of African Catfish <i>Clarias gariepinus</i>in Lake Manzala, Egypt

Advances in Bioscience and Biotechnology 2015年第7期6卷 464-469页

作者： rewaida abdel-gaber Manal El Garhy Kareem Morsy Zoology Department Faculty of Science Cairo University Cairo Egypt

The African catfish, Clarias gariepinus, is generally considered to be one of the most important tropical catfish species for aquaculture purposes. Parasitological investigation was performed in two hundred naturally collected fish samples during the period of February to December 2014. The prevalence of gastrointestinal helminth parasites infecting C. gariepinus was investigated. A total of 249 helminth parasites belonging to four genera were recovered from 130 (65%) examined fish samples. They were digenea Orientocreadium batrachoides, cestode Polyonchobothrium clariae, and nematode Procamallanus laevionchus and Camallanus polypteri. Majority of the recorded parasites were found in the intestine. Female fish samples had higher prevalence rate 72 (90%) than males 58 (48.33%), and there was no significant difference (P > 0.05) in infestation rate between the two sexes. The relationship of host size (weight/length) 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. In addition, this study determines the effect of fish age on the prevalence and intensity of gastrointestinal parasites.

The present study was to investigate the copepodid species infecting rosy goatfish Parupeneus rubescens,one of the most economically important fishes in the Arabian Gulf.A copepodid species identified from the examined fish specimens belongs to the Taeniacanthidae family and is labeled as Taeniacanthus yamagutii Shiino,1957,mainly depending on its morphological,morphometric,and ultrastructural characteristics,in particular the presence of maxilliped claw with a conspicuous digitiform process at the base,the terminal process of the second maxilla stout,and a setiform element at the tip of each exopod spine of legs *** order to ensure the accurate identification and exact taxonomic characterization of this species,the 28S rRNA gene sequence was *** result revealed that the present copepodid species belong to the Taenicanthidae family and has a close relationship with Taeniacanthus yamagutii(gb|KR048852.1)in the same *** present study demonstrated that the rosy goatfish is a host for Taeniacanthus species,which will be helpful to prevent this parasitic infection.

Dammam City is one of the gorgeous coastal areas in the Arabian Gulf of Saudi *** present study aimed to ex-amine one of the copepod species infecting the rosy goatfish that represents a highly consumed fish species by the local population in the Arabian *** copepod species isolated from the infected fish specimens belong to the family Taeniacanthidae and was iden-tified as Irodes parupenei Ho and Lin(2007),primarily based on its morphological,morphometric,and ultrastructural characteris-tics,especially the structures of the dorsal cephalic area,segmentation of the first antenna,the absence of the maxilliped claw in the fe-male specimens,and the setation and spinulation of the legs 2-4 for the adult females are of great significance in the taxonomic *** 18S rRNA gene sequence was analyzed to ensure the precise identity and exact taxonomic status of the copepod *** result showed that this copepod species belong to Taenicanthidae and closely related to Irodes sauridi(gb|JF781550.1)in the same *** details on the specificity of the goatfish for Irodes species and identifying these parasitic taxa using molecular analysis are given in the present study.
