Abstract This study evaluated the parasite fauna on the gills of spotted goatfish Pseudupeneus maculatus captured in the dry and rainy seasons in the coast of the State of Pernambuco, Brazil. Eight parasite species were identified belonging to the following taxa: Monogenea (Haliotrema caraïbensis, Haliotrema caballeroi and Haliotrema golvani); Crustacea (Rocinela signata, Hamaticolax scutigerulus and Caligidae gen. sp.) and Cestoda (Nybelinia indica and Pseudolacistorhynchus noodti). The most prevalent parasites were: Monogenea (100%), H. scutigerulus (35%), N. indica (11.7%), R. signata (8.3%), Caligidae gen. sp. (3.33%) and P. noodti (0.83%). Values of infestation are compared to other studies, and the uncommon occurrence of Trypanorhyncha on the gills suggests that the spotted goatfish could be an intermediate host for the parasite.

Between October 2001 and March 2002, 103 specimens of A. tricolor from Angra dos Reis (23°01'S, 44°19'W), in the coastal zone of the State of Rio de Janeiro, Brazil, were analyzed in order to study their metazoan parasite infracommunities. Ten species of metazoan parasites were collected: 4 digeneans, 1 cestode, 1 acantocephalan, 2 nematodes, 1 copepod, and 1 hirudinean; 77.7% of the fishes were parasitized by one or more metazoan, with a mean of 3.5 ± 6.2 parasite/fish. Digenean was the most dominant with 4 species that accounted for 53.2% of the total parasites collected; Ergasilus sp. was the most abundant species. Abundance and prevalence of Parahemiurus merus (Linton, 1910) were positively correlated with the total length of host. Relationships between total body length of fish and both total parasite abundance and mean parasite species richness were observed. Mean parasite diversity of species was correlated to host's total length, with significant differences found between male and female fishes. Two pairs of larval species showed significant positive association and covariation. The metazoan parasite infracommunities of A. tricolor presented dominance of larval endoparasites; correlation of parasite abundance, diversity, and species richness with host total length; and low number of parasite interspecific relationships. The parasite community of A. tricolor showed some similarities with the parasite community of another South American Atlantic engraulid.Entre outubro de 2001 e março de 2002, foram examinados 103 espécimes de A. tricolor provenientes de Angra dos Reis (23°01'S, 44°19'W), litoral do Estado do Rio de Janeiro, Brasil, para o estudo de suas infracomunidades de metazoários parasitos. Foram coletadas 10 espécies de metazoários parasitos: 4 digenéticos, 1 cestóide, 1 acantocéfalo, 2 nematóides, 1 copépode e 1 hirudíneo; e 77% dos peixes estavam parasitados por 1 ou mais metazoários, com média de 3,5 ± 6,2 parasitos/peixe. Os digenéticos foram dominantes, representando 53,2% do total de parasitos coletados, e Ergasilus sp., a espécie mais abundante. A abundância e a prevalência de Parahemiurus merus (Linton, 1910) foram positivamente correlacionadas ao comprimento total dos hospedeiros. Relações entre a abundância parasitária total e a riqueza parasitária média ao comprimento total dos hospedeiros foram observadas. A diversidade parasitária média foi corrrelacionada com o comprimento total dos hospedeiros, apresentando diferenças significativas entre os peixes machos e fêmeas. Dois pares de espécies de larvas apresentaram associação e covariação positiva significativas. As infracomunidades de metazoários parasitos de A. tricolor demonstraram dominância nas larvas de endoparasitos, correlação entre abundância parasitária, diversidade e riqueza de espécies e o comprimento total dos hospedeiros e o baixo número de associações interespecíficas parasitárias. A comunidade parasitária de A. tricolor apresentou algumas semelhanças com a comunidade parasitária de outros engraulídeos do Atlântico Sul-Americano.
