Abstract
Parasites in 61 individuals of eight species of coral reef fish (Caracanthus maculatus, Scorpaenodes sp., Sebastapistes cyanostigma, Gobiodon unicolor, Paragobiodon modestus, P. echinocephalus, Pseudocheilinus hexataenia, and Halichoeres sp.) were studied in April–May 2012–2014 and November 2017. All studied fish were symbionts of corals of the genera Acropora and Pocillopora. The parasites found were the nematodes Spirocamallanusistiblenii, Raphidascaris (?) sp., and Ascarophis sp., a larva of the cestode Nybelinia sp., as well as metacercariae of the trematodes Stephanostomum sp. 1, Stephanostomum sp. 2, and Trematoda gen. sp. The low prevalence, infection rate, and diversity of parasites could be related to low population numbers of fish hosts, their efficient individual anti-parasitic defense, as well as to predation by corals that prey on dispersal stages of parasites.
