“…Parasites have been known to cause changes in growth, behavioral changes which are negative in reaction and mechanical injury (Iwanowicz 2011). In this study, prevalence rate was low (9.8%) when compared to other reports on fish parasites in the tropics reservoir (Okoye et al 2014;Bedasso 2015;Oso et al 2017). In order to survive, reproduce and have access to food, parasite depends on their host ).…”

This study investigated fish parasites in relation to limnological variables of the Esa-Odo reservoir since the quality of the aquatic environment might influence parasitic infestation in fish. The purpose of this study was to provide information on the parasite species of the reservoir due to their public health concern and their relationship with selected water quality parameters. The water quality and parasite examinations were analyzed based on standard protocols in the laboratory. The results showed that water quality parameters were not significantly different (p > 0.05) across the zones. Seasonally, mean water temperature, pH, TDS, DO, organic matter, COD and turbidity were significantly different (p < 0.05) across the different zones of the reservoir while electrical conductivity, alkalinity, NO3-, and PO43- were not significantly different (p > 0.05). Clinostomum tilapiae, Clinostomum sp., Euclinostomum heterostomum, Procamallanus leavionchus, and Lytocestus sp. were recovered in all the fish sampled. The overall prevalence of the fish parasites was 9.8% with an intensity of 2.13. The result indicated fish parasites had a strong positive correlation with certain water quality properties and parasite abundance which suggested that water quality could determine parasitic loads in fishes of the Esa-Odo reservoir.

“…Studies have shown that water pollution affects parasitism either positively or negatively. According to Oso et al (2017) [46] , when hosts (fish) of parasites are stressed as a result of natural and anthropogenic stressors, it reduces their ability to resist parasitic infections, therefore parasitism will increase. Akinsanya et al (2020) [5] also reported the destruction of plankton community through conventional fishing and other anthropogenic activities as a promoter of food competition which could contribute to either high or low prevalence of parasitic infection.…”

This study survey the parasitic fauna of some fishes collected from Osun river, Osun State Southwestern Nigeria with aims of evaluating the prevalence, intensity, pattern and distribution of parasites among the collected fishes. A total of 258 fish specimens consisting of 9 species belonging to 7 families were procured by fishermen between March and August, 2021 with the use of cast net. Fish samples were examined, dissected and parasites were removed, identified and counted by employing standard techniques in parasitology. A total of 49 out of 258 collected fishes were infected with ten different parasites with an overall prevalence of 22.9%. The recovered parasites include four cestodes (30%), two digenetic trematode (23.23%), one monogenean, (1.01%), one acanthocephalan (8.08%), one secernetean (32.32%) and one nematode (5.05%). Generally, parasitic prevalence was not size dependent and the female fishes were observed to be more parasitized than male (p˃0.05). The mean intensity and abundance of parasites were higher in the stomach and intestine than the gills. Fish parasitism is one of the major problems facing fish production and could be sustained with high degree of pollution as indicated in this study. Hence pollution control and regular examination of the water bodies should be advocated to prevent low fish performance and production.

“…The public health issues caused by zoonotic parasites and the prevention of their transmission to humans and other animals are of great importance. Information on the occurrence, prevalence, and pathogenicity of fish parasites and diseases is essential in aquaculture production, as such information enables aquaculturists to apply correct prevention and control measures in their fish production and also provide useful information on their public health-related concerns (Oso et al, 2017). Since fish is an affordable and accessible source of animal protein for Nigerian families (Eric et al, 2018), the marketing of freshly captured live fish is common in the markets (Bimal et al, 2019).…”

Fish is a cheap and important source of protein and minerals for humans. Clarias gariepinus accounts for over two-thirds of the fish consumed by an average Nigerian family. Various parasites infect C. gariepinus in the wild and in cultured environments, where they are captured and taken to various selling points to be sold to consumers. The present study is aimed at determining the occurrence of parasitic infection in live C. gariepinus from Jimeta Modern Market, Yola, Adamawa State, Nigeria. A total of 30 C. gariepinus were randomly bought from five different fish vendors, six from each. The fish were transported to the Department of Microbiology, Modibbo Adam University, Yola for further studies. The fish sexes were determined before they were examined for parasitic infections. Skin scrapings were obtained, and the gills were examined for ectoparasites while the gastrointestinal tracts were dissected and examined for endoparasites. Parasites were isolated and identified using standard parasitological procedures. Five classes of parasites were identified, namely, Nematode, Trematoda, Protozoa, Cestoda, and Hirudinea. The prevalence of parasites in C. gariepinus sampled from Jimeta Modern Market indicated 57.14% in the male C. gariepinus, while female C. gariepinus were infected with a prevalence rate of 42.85%. This study revealed some major groups of fish parasites that are of zoonotic importance.
