The "Peruvian hake" Merluccius gayi peruanus (Ginsburg, 1954), is the most abundant and economically important fish in the trawl fishery in Peru. The aim of this study was to assess the parasitological indices of Peruvian hake M. gayi peruanus from the Fishing Terminal of Chorrillos during the months of January to February 2014. Parasites were collected, fixed, preserved and quantified using standard procedures. A total of fifteen parasite species, with a mean total abundance and species richness of 1.55 and 0.90 was collected. Ectoparasites were represented by the monogenean Anthocotyle americana and copepod Caligus debueni and Neobrachiella insidious pacifica. Endoparasitic digeneans were Aporocotyle wilhelmi, Derogenes varicus and Lecithochirium genypteri. The tapeworms were Diphyllobothrium pacificum, Diphyllobothrium arctocephalinum, Callitetrarhynchus gracilis and Clestobothrium cr...
