A total of 198 specimens belonging to four fish species (Thunnus tonggol, Sphyraena barracuda, Pomadasys argenteus and Lutjanus gibbus) were purchased from Al-Mehwat fish market, Hodeidah, Yemen and inspected for acanthocephalan infections. Two acanthocephalans were detected. Juveniles of Serrasentis sagittifer were recovered from the intestine, pyloric caeca, body cavity, mesenteries and some internal organs of the above- named fishes with prevalence of 11.7%, 11.9%, 24% and 4.4%, respectively and a mean intensity of 3.3, 2.2, 5 and 2, respectively. Generally, male fishes showed higher values of infection in comparison with female fishes. Encysted juveniles of Gorgorhynchus sp. were recovered from the intestinal mesenteries of T. tonggol only with a prevalence of 3.3% and intensity of 2.5. The occurrence of the above-named acanthocephalans represents their first record from the Yemeni fishes of the Red Sea

-Skin and gill parasites found in juvenile Atlantic bluefin tuna (Thunnus thynnus) caught in the Bay of Biscay, northeast Atlantic, were examined with the aim of finding biological tags. The degree of infection of different microhabitats was analyzed and the annual prevalence by species of parasite obtained. Of the specimens examined, 98% had parasites, and the gills were by far the most infected microhabitat, followed by the skin and the pectoral fin. Within the gill cavity, parasites were most commonly found in the afferent margins of the primary lamellae. Three species of Copepoda were identified, two species of Monogenea, and eleven Digenea. Thus, ten species (Digenea: Didymozoidae) and a new host record for Copiatestes thyrsitae (Digenea: Syncoeliidae) were recorded in Thunnus thynnus. The suitability of the different external parasites found is discussed and gill didymozoids are put forward as useful biological tags. Confusing taxonomy within this digenean family makes species identification of the different morphotypes difficult. However, their habitat specificity in hosts can be a good tool to differentiate morphotypes and characterise host individuals.
