Comparative study of the degree of incidence of macroparasites in six species of Sebastes (Pisces, Scorpaenidae) from the northwestern coast of Baja California, Mexico

Abstract

Examined Sebastes constellatus, S. elongatus, S. rosaceus, S. umbrosus, S. helvomaculatus and S. chlorostictus. The nematode Anisakis sp. and monogenean trematode Microcotyle sp. were registered in all species of rockfish but others, such as the anchor parasite copepod Lernaea sp. and digenean trematode Opecoelus sp., were of exclusive occurrence in S. umbrosus and S. rosaceus, respectively. Nematodes were the most dominant parasites in all the rockfish species, with an incidence percent of 82.4, followed by digenean trematodes (9.5%) and cestode worms (3.1%). -from Authors
