Parasites of the Mutton Snapper Lutjanus analis (Perciformes: Lutjanidae) in Alagoas, Brazil

A parasitological survey was carried out on a sample of sixty mutton snappers (Lutjanus analis) that were caught on the coast of Alagoas, northeastern Brazil. The parasite diversity and infection levels were low. The ectoparasite Rocinela signata Schioedte & Meinert, 1879 (Isopoda: Aegidae), and larvae of two endoparasites, Trypanorhyncha gen. sp. andHysterothylacium sp. (Nematoda: Anisakidae), were detected. The significance of these parasites is discussed in the context of their transmission pathways and potential impact.
