Abstract

Ictioparasitology is a science that has, among its objectives, assisted in the understanding of the interactions between fish and their parasites. Crustaceans are one of the most popular invertebrate groups exhibit a striking diversity of forms, habits and sizes, are found at all depths in the various marine and freshwater of the earth, and Copepod class are the largest group crustacean parasites in fish, with economic importance, which may result in high mortality. In the present work the biodiversity of the parasitic copepods of skipjack tuna (Katsuwonus pelamis) from the Southwest Atlantic Ocean - Rio Grande do Norte, Brazil, is reported. Parasitic ecological indexes (prevalence, mean intensity and mean abundance) were also calculated. Fish were collected in the coastal area of Areia Branca (state of Rio Grande do Norte) from 2015 to 2016. Standard biometrics of the hosts was also taken. Four species were identified infecting branchial chamber and body skin of K. pelamis.: Caligus pelamydis (17.65%), C. bonito (36.27%), C. productus (37.25%) and Pseudocycnus appendiculatus (8.82%).
