Abstract

The aim of this study was to evaluate the parasitic community of Cabinza grunt Isacia conceptionis (Cuvier y Valenciennes, 1830) (Haemulidae) (n=123) from the Fish Market of Chorrillos, Lima, Peru during December 2010 to March 2011. Parasites were fixed, preserved and quantitated by standard procedures. A total of 95 parasites of seven species were collected with an average abundance of 0.77. The average species richness was 0.46. The four most prevalent parasites and mean abundance were Choricotyle isaciencis Oliva, Gonzalez, Rus y Luque, 2009, Corynosoma obtuscens (Lincicome, 1943), Proleptus carvajali Fernández y Villalba, 1985, and Clavella simplex Castro y Baeza, 1985. Parasites of I. conceptionis indicate that the three indices of aggregation [Dispersion (ID), Discrepancy of Poulin (D) and Negative Binomial (k)] mostly showed an aggregated distribution. The prevalence of C. isaciencis correlated with the total length of the host fish. In relation to kn (relative condition factor), none of the fish parasitized by C. obtuscens, C. isaciencis, ectoparasites and endoparasites presented higher values compared with non-parasitized fish. The gonadosomatic index (GSI) was not associated with any of the indices of parasite ecology. Equity indices of parasitefauna showed relatively high values. Instead, dominance rates were low. Rates of interactivity (CC50) of ectoparasites and endoparasites indicated that communities were isolated.
