摘要

The present study was conducted to determine if parasite induced mortality existed in a "puyen" population in Moreno Lake, southern Argentina. Data on both parasite abundance and degree of aggregation of parasite frequency distribution showed the absence offish mortality induced by A. apophalliformis. The "puyen" Galaxias maculatus is a small native fish that inhabits southern South America and Oceania. This is a protected species in Nahuel Huapi National Park and Reserve, southern Argentina. Acanthostomoides apophalliformis is a digenetic trematode whose metacercaria stage frequently parasitizes "puyenes", generally located in the liver (Revenga and Scheinert, 1999a).
