Resumen

OLIVA, Marcelo E.; LUQUE, Jose L.  y  IANNACONE, Jose A.. The metazoan parasites of Stellifer minor (Tschudi, 1844): an ecological approach. Mem. Inst. Oswaldo Cruz [online]. 1990, vol.85, n.3, pp. 271-274. ISSN 0074-0276.  http://dx.doi.org/10.1590/S0074-02761990000300003.

A quantitative and qualitative analysis of the parasite fauna of the sciaenid Stellifer minor (Tschudi) from Chorrillos, Peru, was made. Some characteristics of the infectious processes, in terms of intensity and prevalence of infection, as a function of host sex and size, are given. Moreover, comments on the characteristics of the parasite fauna, related with host role in the marine food webs are included. The parasite fauna of Stellifer minor taken of Chorrillos, Peru, include the monogeneans Pedocotyle annakohni, Pedocotyle bravoi, Rhamnocercus sp. and Cynoscionicola sp., the digenean Helicometra fasciata, the adult acantocephalan Rhadinorhynchus sp. and the larval Corynosoma sp., the nematode Procamallanus sp., the copepods Caligus quadratus, Clavellotis dilatata and Bomolochus peruensis and one unidentified isopod of the family Cymothoidae. A distinctive characteristic of the parasite fauna (Metazoa) of S. minor is the almost absence of larval forms.
