الملخص الإنجليزي
Fish diseases especially those caused by parasites are major problems
confronting fish farmers globally. This study investigated the gastrointestinal helminth
parasites of Heterotis niloticus (African Bony tongue fish) from the Anambra River
basin over 12 months (January to December, 2013). A total of 294 fish were caught
from three locations along the Anambra River, and transported to the laboratory for
morphological and parasitological studies. Four species of helminth parasites were
isolated comprising one cestode (Sandonella sandoni), two nematodes
(Procamallanus laeviconchus and Dujardinascaris species) and one acanthocephalan
(Tenuisentis niloticus). Out of the 294 fish species examined, the overall prevalence of
infection was high (72.8%) with a mean abundance of 0.77 of helminth parasites per
fish. Prevalence of helminth infection increased with increasing host weight, although
there was no significant relationship (p=0.144). Similarly, there was no significant
relationship between the length of fish and helminth infection. The intestine was found
to be the site for most of the recovered parasites. More parasites were recovered during
the rainy season. It can be concluded that H. niloticus is a new host record for P.
laeviconchus. It is therefore necessary to be aware of the parasitofauna for possible
zoonotic disease.
