Resumo: | Ninety specimens of red porgy, Pagrus pagrus (Linnaeus, 1758) (Osteichthyes: Sparidae) collected from the coastal zone of the State of Rio de Janeiro, Brazil (21-23º S, 41-45ºW), from October 1998 to March 2000, were necropsied for parasite studying. All fish were parasitized by metazoan. Twenty-two species of parasites were collected. The nematodes were 59% of the total parasitic specimens number. Contracaecum sp. larvae were the dominant species with highest prevalence and abundance. Abundance and prevalence of cymothoid isopod were positively correlated with host total length, while the prevalence of Parahemiurus merus (Linton) and Polymorphus sp. were negatively correlated with host total length. The host gender did not influence any parasite species prevalence or abundance. The mean diversity in the P. pagrus infracommunities was H=0.306±0.119, with no correlation with the host’s total length and no significant difference between male and female fish. Three pairs of species shared a significant positive covariation, and two pairs shared significant positive association between their abundances and prevalences, respectively. Negative parasite species association or covariation were not found. Qualitative similarity was observed between the ectoparasite infracommunities of P. pagrus, at the genus level, with other sparid fishes of the world. |

Todos os peixes examinados estavam parasitados. Vinte e duas espécies de parasitos foram coletadas. Os nematóides corresponderam a 59% do total de espécimes de parasitos coletados. Contracaecum sp. foi a espécie dominante, com os maiores índices de prevalência e abundância parasitária. A abundância e a prevalência do isópode cimothoídeo apresentou correlação positiva com o comprimento total do hospedeiro, enquanto a prevalência de Parahemiurus merus (Linton) e Polymorphus sp. apresentaram correlação negativa. O sexo do hospedeiro não influenciou na prevalência e abundância das espécies de parasitos. A diversidade média das infracomunidades de P. pagrus foi H=0,306±0,119 e não apresentou correlação com o sexo e o comprimento total do hospedeiro. Três pares de espécies apresentaram covariação positiva significativa e dois pares de espécies apresentaram associação positiva significativa entre suas abundâncias e prevalências, respectivamente. Associações e covariações negativas não foram observadas. No presente trabalho foi observada similaridade qualitativa das infracomunidades de ectoparasitos de P. pagrus, a nível de gênero, com outros peixes esparídeos.Universidade Estadual De Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/232210.4025/actascibiolsci.v24i0.2322Acta Scientiarum.
