title: Parasites of coral reef fish recruits, Epinephelus merra (Serranidae), in French Polynesia.
abstract: Honeycomb grouper recruits Epinephelus merra (Serranidae) from 2 recruitment events on Moorea Island, French Polynesia, were examined for internal parasites. Trypanorhynch blastocysts (Eucestoda: Trypanorhyncha) and encysted phyllobothriid metacestodes (Eucestoda: Phyllobothriidae) were found in recruits from both events. Fish from the second event were examined later as juveniles and were found to harbor apparently melanized parasites. Neither parasite was found in adults. Evidence suggests these patterns are not due to differential mortality among recruits but to the elimination of parasites by host immune responses. The data also suggest that pelagic fish larvae may represent a dispersal mechanism for parasites if transfer occurs before the death of the parasite.
