Parasites of larval and juvenile freshwater fish in Australia: how small is too small to be infected? Charles Sturt University, Australia Knowledge of the parasitic infections of freshwater fish in Australia is sporadic but is concentrated on reports of infection in larger specimens. The dynamics of infection with parasites in larval and juvenile freshwater fish is unknown. Thus, this study utilised fish specimens previously collected for a river health monitoring program to determine levels of parasitic infection: the native Macullochella peelii, Retropinna semoni, Hypseleotris spp., Phylipnodon grandiceps, Macquaria ambigua, and the introduced Cyprinus carpio. Dissections of fish found six different morphotypes: the monogenean Dactylogyrus extensus, the adult nematode Procamallanus (Spirocamallanus) sp., the mite Hydrozetes sp., and the unidentified larval cysts, larval nematodes and adult nematodes. Histological examination determined infections with the protozoans Trichodina sp. and Chilodonella sp. The smallest fish found to be infected with a parasite was a 6mm C. carpio. | |
