The study was conducted in Gesedaddo's farm, Yola, Adamawa state, Nigeria to determine the prevalence of parasites infecting Clarias gariepinus between June to November, 2016. A total of one hundred and thirty-two (132) fish were sampled for parasitic investigation. Out of these, cultured adults (66) and cultured juveniles (66) respectively were procured from the farm and examined for parasites using the keys of fresh water fish parasite pictorial guide and were examined for parasitic infections using direct wet mount microscopy and stained smears. A total number of 43 adult Clarias gariepinus were infected out of which 132 parasites were identified, while in juvenile Clarias gariepinus, a total number of 10 fish were infected in which 30 parasites were identified in Gesedaddo's farm. Seven (7) classes of parasites and eleven (11) parasite species, which are namely, Piscinoodinium, (Dinoflagellata), Coccidia, Spironucleus vortens, (Flagellata), Chilodonella, Tetrehymena, (Motile ciliate), Capillaria, Contracaecum, (Nematoda), Microsporidians, (Protozoa), Saprolegnia sp, (Oomycota), Digeneans, and Planarian (Trematoda) were recorded from the gills, stomach, intestine, and skin mucus of the cultured Clarias gariepinus on the farm. Parasitic infestation was higher in the intestine with 63 (47.73) and the least was identified 6 (4.55) on the skin for adult Clarias gariepinus while the highest number of parasites identified in juvenile Clarias gariepinus was found on the skin with total number of 11 (36.67). Among the class of parasites identified, it was recorded that the highest parasitic load occurred most in the class protozoan with 45 (34.09%) and 17 (56.67) in adult and Juvenile C. gariepinus respectively. The Chi square value shows that there was no significant difference (p>0.05) between the prevalence and intensity of parasitic infection in adults and juvenile C. gariepinus based on sex. Parasitic infestations in the adult and juvenile female were significantly higher than in the adult and juvenile male in cultured Clarias gariepinus. There was a significant difference between incidence of infestation, standard length and body weight of Clarias gariepinus while there was no significant difference (p> 0.05) between parasitic load.

This study was conducted to determine the prevalence of gastrointestinal helminth parasites in Clarias gariepinus with the view of quantifying its helminthic burden in Abuja. The study was carried out in three area Councils of Abuja, Nigeria, between the months of April and August 2015. A total of 83 live fishes (Clarias gariepinus) which includes 28 males and 55 females were randomly purchased from local fishermen and were subjected to examination for gastrointestinal helminth parasites. The lengths and weights of the fishes were measured prior to dissection and the parasites recovered were identified. Results indicated that 56 of the examined fishes were infected with various species of helminth parasites, giving a prevalence of 67.5%. Parasites were identified as Procamallanus laevionchus (32.5%), Rhabdochona congolensis (18.1%), Polyonchobothrium clariae (10.8%), Allocraedium species. (3.6%) and Heterophyid flukes (2.4%). The highest prevalence was recorded for nematodes (50.6%) followed by cestodes (10.8%) and trematodes (6.0%). Worthy of note, was the recovery of Heterophid flukes in this study which have not been previously reported in Nigeria and pose a great zoonotic threat. It was observed that fishes of standard length range of 20-30cm (82.4%) were more infected than those of 30-40cm (65.0%) and 40-50cm (61.5%). The highest prevalence of infection (78.6%) was recorded in fishes with body weight of 500-600g while the lowest (58.8%) was recorded in fishes with body weight of 600-700g. The males had higher percentage prevalence (67.9%) than the females (67.3%). The result of the study indicated that the association (P˂0.05) between the prevalence of infection, sex, length and weight of the host was not statistically significant (χ 2 = 0.00289, 2.24 and 1.55; degree of freedom= 1, 2 and 5 respectively). The helminths recovered were found to parasitize the stomach and intestinal lumen, the latter being more affected.

“…Fish, like other protein-rich animals, are susceptible to a range of microorganism attacks (Ashadeet al, 2013). Parasitic infestations in fish are widespread in tropical regions (Soliman and Nasr, 2015), with different parasites associated with various fish species. Tropical freshwater fish species like T. zillii, C. gariepinus, B. domac, and B. bayad serve as definitive, transport, or intermediate hosts in the life cycle of numerous protozoan, metazoan, and crustacean parasites (Ashadeet al, 2013).…”

Fish parasitic infections inflict a most importanteconomic concern on fish farming industries. Helminthic infestations can cause a variety of fitness difficulties as well as economic sufferings for fishing populations. Prevalence of ecto-parasites fauna in silver catfish Bagrusbayad from Zobe reservoir, Katsina Nigeriawas inspected to comprehend the healthiness conditionof the fish, possibledanger to their existence as well asprotection of consumption of fish from the water body.The current study was undertaken between August and October, 2023 to determine the prevalence of fish ecto-parasites of Bagrusbajad and the associated risk factors in Zobereservoir Dutsin-Ma, Katsina State, Nigeria. A total number of108 fish samples were collected and examined from Zobe reservoir. The fish was identified as well as separated based on their sex before being transferred live to the Fish Biology laboratory, Federal University Dutsin-Ma, Katsina State for additional evaluation. Out of 108 fish samples from Zobe, 88 were male and 20 were female. Fish parasites recovered and their prevalence among Bagrusbajad obtained from Zobe reservoir includes; Tricodinaspp 17 (68%), and Gyrodactylusspp 8 (32%). The prevalence of parasites recovered from the fish species in this study was low. In conclusion, Bagrusbajad from Zobe reservoir were infected by parasites that are of economic importance. The findings suggest that the observed parasitic infections may adversely affect Bagrusbajad and if not well managed, could also infect human beings who consume the fish. It is therefore recommended that communities along the reservoir should desist from activities likely to increase parasite load, also, the part organs of harvested fishes from the study area should be discarded rather than consume to prevent zoonotic diseases.
