Acanthostomoides apophalliformis (Trematoda: Cryptogonimidae) does not cause detectable mortality in Galaxias maculatus (Teleostomi: Galaxiidae)

Abstract

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 of fish mortality induced by A. apophalliformis.
