چکیده

This study investigated the parasitism of three species of fish species, Pagellus bogaraveo, (family Sparidae), Sardina pilchardus (family Clupeidae) and Umbrina canariensis (family Sciaenidae), collected from the Atlantic coast of Morocco. A total of 5419 fish specimens were examined. Among them, 3600 fish  individuals of Sardina pilchardus, 920 of Umbrina canariensis and 899 of Pagellus bogaraveo, were found to carry 328 isopod parasites of the species Anilocra physodes (family Cymothoidae). Most of these ectoparasitic isopods were primarily located on the body surface or within the gill chambers of their hosts. Parasitism was quantified using various parasitological indices (prevalence, intensity which is the mean number of parasites per infected host and abundance) calculated for each fish species. The results showed that infestation rates by A. physodes were relatively low and did not exceed prevalence of 11.11%. The mean infestation intensity is ranged between 1 and 2 parasites per infected fish, while, abundance values remain below 0.14 parasites per examined fish across all host species. These findings indicate that infestation levels are strongly associated with the host species. Overall, this study provides valuable insights into the effects of this ectoparasite crustacea on fish health, emphasizing the need for fisheries management strategies and marine conservation in the region.
