ABSTRACT
A study of helminth parasites of
Clarias gariepinus, Oreochrom,s niloticus, Chiysichthys nigrodigitatus and
Malapterurus electricus was carried out from fish landings in Imo River basin
Owerrinta from May to August 2013. A total of 100 fishes were examined for
infestation by helminth parasites. The live fish were transported in plastic
1bowls containing river water and ice, covered with nylon netting to the
veterinary laboratory in Michael Okpara University of Agriculture, Umudike. The
fish were dissected along the abdominal region from the anal opening to the
heart region with the aid of a surgical blade. The contents of the stomach and
intestines were scraped into a petri-dish containing brine solution and viewed
under a light microscope. Afterwards, the organs were cut open, put into petri
dishes and thoroughly searched for parasites using a microscope with a
magnification of x400 (objective X lens). 35 specimens of 0. nioticus were
examined. All the examined specimens were infested giving the prevalence of
100%. 33 specimens of C. gariepinus were examined and 32 were infested giving
the prevalence of 96.97%. 17 specimens of C nigrodigitatus were examined and 11
were discovered to be infested giving a prevalence of 64.71%. 15 specimens of
M. electricus were examined, 8 were infested giving a prevalence of 53.33%.
Generally, all parasites encountered in this study belong to six classes which
are nematoda, cestoidea, trematoda, acanthocephala, branchiura and hirudinea.
Females had more worm load than the male fish with a prevalence rate of 82.86%
and 73.33% respectively. There were significant differences in prevalence of
parasites with respect to size (length and weight) of fish species.
