The fish Sicyases sanguineus (Müller & Troschel, 1843) lives in rocky intertidal coastal zone attached to rocks and under the influence of waves. It is found between Salaverry (Peru) to Punta Arenas (Chile). Between August and September 2009, 99 specimens of S. sanguineus were obtained from the Fisheries Terminal Chorrillos, Lima, Peru to assess its parasite fauna. Of the fish tested, 47 were females and 52 were males. The fish had a total length of 24.5 ± 4.5 cm (11 cm to 35 cm). The parasite assemblage registered a higher percentage of endoparasites (83.3%) than ectoparasites. The mean parasite species richness was 1.05 ± 1.4 (0 to 4). Twenty hosts showed no parasite (20.2%) and 79 hosts showed infection with at least one parasite (79.8%). The site of infection, prevalence, and mean abundance of the six parasite species found was: a copepod Acanthochondria sicyases (Kroyer, 1863) (gills and gill chamber, 63.63% and 2.33) and five trematods Proctoeces lintoni Siddiqui et Cable, 1960 (intestine, 9.1% and 0.18), Proctoeces sp. (intestine, 15.15% and 0.49), Helicometrina nimia (intestine, 4.04% and 0.05), Lecithastheridae sp. (intestine, 7.07% and 0.27) and Prosorhynchoides sp. (intestine, 6.06% and 10.67). The index of significant parasites showed that Prosorhynchoides sp. presented the highest prevalence. All parasites showed a contagious distribution. No relationship was found between host sex or length and prevalence and abundance of parasites, with the exception of A. sicyases.
