The present study investigates the parasitic biodiversity of the Axillary seabream Pagellus acarne (Risso, 1827), which were caught in western Algeria (western Mediterranean). The examination of 104 fishes landed in the port of Béni Saf, resulted in the identification of 440 individuals of parasites. Our study identified 5 species of Nematodes parasitizing the digestive system: Anisakis physeteris, Hystetothylacium fabri, Hysterothylacium aduncum, Hysterothylacium sp., Cucullanus sp., which belong to two large families: Anisakidaes and Cucullanidaes. The Hysterothylacium fabri species were well represented in our samples (63,46%). We have also identified Tetraphyllidea larvae of the Scolex pleuronectis with a prevalence of 23.07%. In addition to the presence of the Anisakis physeteris for the first time on the Algerian coast.
