Title : Helminth parasites relationship with the cut fish Clarias anguillaris (Linnaeus, 1758) from Burkina Faso, West Africa
Abstract:
Clarias anguillaris is a specie liked by population in Burkina Faso and it is consumed fresh, fumed and dry. But more information on its pathologies and parasites are not enough known. Whereas fish parasites are ecologically important in managing the biodiversity of ecosystems. In this work, the helminths parasites of the cut fish (Clarias anguillaris), widely consumed in Burkina Faso and used in fish farming, were studied. The host fish were sampled in three reservoirs in Burkina Faso; localized in the urban area (urban park Bangreweogo) and rural area (reservoirs of Loumbila and Ziga). At each sampling, the host fish were examined for parasites. The gills were collected and observed to harvest ectoparasites. The digestive tract, for its part, was separated from the secondary organs after dissection, and each part was examined for the collection of mesoparasites and endoparasites. Others organs such us muscle, gall bladder, liver and mesenteries were examined for parasites. Harvested parasites were keep in alcohol 70°. A total of 336 specimens of C. anguillaris on the studies sites were examined and 319 (94.94%) were infested. Twenty (20) parasites species were identified and these parasites are belonging to three families such us Nematoda, Cestode and Trematoda. The Different parasites harvested had specific localization according to their stage and their specificity. The larvae are intratissular and the adults are in the lumen of the organs. So Trematode larvae were very abundant in the muscle. Larvae of Nematoda were observed in the mesenteries and liver, cestodes were observed in intestine, gall bladder and bile duct.
