“…On the other hand, the incidence of Acanthostomum spiniceps infection in the present work was 2.2%, lower than that reported by Morsy et al [15] who recorded incidence rate of Acanthostomum spiniceps infection in Lates niloticus = 40%, this may be attributed to the differences of fish host. With regard to Orientocreadium batrachoides, it was in agreement with that was reported by Tepe et al [17] who recorded this species from Clarias gariepinus from the Asi River (Southern Turkey). The incidence of Orientocreadium batrachoides in the present work was 5.4%, greatly lower than that reported by Tepe et al [17] (76.2%), this may be attributed to the differences of area of infection (the Asi River, southern Turkey, where it was considered as contaminated area since pollution released by agroindustrial plants affects its water quality).…”

The parasitic diseases are one of the potential factors that restrict the development of fish aquaculture because fish parasites not only can cause injuries, but can even lead to death of the fish. The present study aimed to record/update the prevalence and intensity of parasitic helminths in the freshwater catfish "Clarias gariepinus " in Fyoum Governorate, Egypt. A total of 368 Clarias gariepinus samples were collected from Bahr Youssef (line of the River Nile) from Fayoum Governorate during the period from January 2019 to February 2020, and were examined for the presence of helminth parasites. Out of 368 examined fish, 227 (61.7%) were found to be infected with six species of helminthes (three trematodes, two cestodes, and one nematode): Dactylogyrus claridii, Acanthostomum spiniceps, Orientocreadium batrachoides, Polyonchobothrium clarias, Monobothrium sp., and Paracamallanus cythopharynx with infection rates = 13.0%, 2.2%, 5.4%, 9.2%, 13.3%, and 18.5%, respectively. Regarding to the seasonal variations, the obtained results showed that the highest rate of infection was recorded during the spring (76.9%), followed by the summer (70.0%) and the winter (53.5%), while the autumn represented the lowest rate of infection (52.3%). In addition, this study provides additional morphological characters for the parasite Paracamallanus cyathopharynx based on the scanning electron microscopy.

“…The nematodes were collected in warm 70% ethyl alcohol solution and cleaned in lactophenol for 12–24 h. They were then preserved in 70% alcohol plus 5% glycerin solution [ 22 ]. All of the prepared slides were examined to identify the parasite species, as described elsewhere [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ].…”

Fish are a source of high-quality protein with low cholesterol, but they are susceptible to parasitic infections, which have a significant impact on aquaculture, in addition to their zoonotic potential. The present study estimated parasitic infections and evaluated the diversity of zoonotic parasites in freshwater Nile tilapia (Oreochromis niloticus) in Assiut Governorate, Upper Egypt. A total of 300 samples were randomly collected from the Assiut Governorate. These fish were examined for both ectoparasites and endoparasites, followed by the experimental infection of mice with encysted metacercariae (EMC) for the retrieval of the adult worms. The overall prevalence of the variable parasites was 82% (246 of 300). Both ecto- and endoparasites were detected in 41% (123 of 300) of the examined fish. The identified ectoparasites were Gyrodactylus, Dactylogrus, Cichlidogyrus, Trichodina and Icthyophthirius multifiliis, in 5%, 4%, 22%, 6% and 4% of the fish, respectively. The endoparasites were trematodes (Orientocreadium batrachoides 3%), nematodes (Contracaecum. 2%), acanthocephala (Acanthosentis tilapiae 25%) and protozoa that included Isospora and Eimeria spp., in 1% and 8% of fish, respectively. Myxobolus was detected in 2% of the examined fish. The overall prevalence of encysted metacercariae (EMC) was 95% (285 of 300), while infection with macroscopic EMC had a prevalence of 37% and microscopic EMC had a prevalence of 58%. The adult worms recovered from the experimental infections were Prohemistomum vivax and Mesostephanus spp., which belong to the family Cyathocotylidae. Collectively, these findings reflect the relatively high occurrence of parasites among the studied fish, confirming the necessity of strict measures to control infection.

“…The peculiar environmental conditions of geothermal waters in the Sakarya River Basin give excellent potential for the acclimatization of the species and C. gariepinus has been stated as the most severe threat for endemic/ native fish species in the upper Sakarya Basin (Emiroğlu, 2011). C. gariepinus was also reported to exacerbate habitat degradation and the spread of diseases and new parasites (Booth et al, 2010;Tepe et al, 2013).…”

Clarias gariepinus and Oreochromis niloticus are two hot-water fish species of African origin that have been recently reported to occur unnaturally in hot-water resources and springs in the Sakarya River Basin (northwestern Turkey). Within effective planning strategies to maintain native biodiversity, monitoring fishes' well-being can be useful to evaluate the status of nonnative fish populations and their degree of adaptation to new environments. Relative weight (W r) is a condition index widely used to estimate the well-being of fish by comparing the actual weight of a specimen with a standard weight (W s) that is the ideal weight of that fish at that length. In this study, length and weight data of C. gariepinus and O. niloticus, collected throughout the Sakarya River Basin, were used to estimate W s equations. The resulting W s equations were log 10 W s =-3.668 + 1.885 log 10 TL + 0.2087 (log 10 TL) 2 (TL range: 18-45 cm) for C. gariepinus and log 10 W s =-8.796 + 6.751 log 10 TL-0.8479 (log 10 TL) 2 (TL range: 8-28 cm) for O. niloticus. The use of these W s equations to estimate the fishes' condition is suggested as a monitoring tool to assess the status and the best management actions of these two nonnative species populations throughout the Sakarya River Basin.
