AB - Since, approximately 2 decades, there has been a regression
of fish captures in Benin and particularly in the Basin of Ouémé
river. A high parasitic infestation which would affect negatively the dynamics
of the halieutic population, would be one of the probable causes of this regression.
The present study aims to inventory helminth parasites in Synodontis schall
and Synodontis nigrita from the lower Ouémé valley
in South Benin and to estimate their prevalence. A sample of 75 specimens of
the 2 fish species was examined at the laboratory between September and October,
2011. The results revealed high parasitic prevalence in the two species: 82.14
and 78.72%, respectively. Six helminth genus were identified of
which one digenean trematode (Clinostomum sp.), three nematodes (Cithariniella
petterae, Procamallanus laeviconchus, Synodontisia thelastomoides)
and two cestodes Stoeksia pujehuni and Lytocestus sp. Of the three
parasites groups, nematodes are most abundant in both Mochokidae examined; they
are 66.53 and 90.58% of parasites counted, respectively in S. schall and
S. nigrita. Synodontisia thelastomoides has the highest prevalence:
46.43% in Synodontis schall and 42.55% in Synodontis nigrita.
