L’infestation De Cyprinus Carpio (cyprinidés) Peuplant Le Barrage Foum El-khanga (souk Ahras, Algérie) Par Les Monogènes Parasites
Résumé: A seasonal study was carried out on monogenean ectoparasites collected from the fish species Cyprinus carpio (Cyprinidae) caught in the Foum El-Khanga reservoir in Souk Ahras (Algeria) during 2014. A total of 120 fish (30 individuals per season) was examined, producing 193 individual parasites of the subclass Monopisthocotylea. Based on morpho-anatomical criteria, five species of Monogenea were identified, belonging to the genera Dactylogyrus (D. extensus, D. anchoratus, D. arcuatus and D. cyclocirrus) and Pseudacolpenteron (P. pavlovskii). Three of the species are new to the Algerian parasite fauna.The distribution of the calculated epidemiological index shows that infection rates and parasite loads by Monogenea are different over the course of the year. The species D. extensus showed the highest prevalences in spring (P = 53.33%) and summer (P = 60%), whereas D. cyclocirrus (P = 50%) and P. pavlovskii (P = 40%) are mainly present in autumn. D. anchoratus and D. arcuatus showed lower prevalence in winter (P = 3.33%). Statistical analysis confirms the influence of microhabitat (arcs within each gill), season and size of the host on the overall rate of infestation. Keywords: Monogenean parasites, Cyprinus carpio, Foum El-Khanga reservoir, Parasitism, Season.
