摘要

Sampling in Iliamna Lake, Alaska, U.S.A. revealed that a greater proportion of coastrange sculpins Cottus aleuticus were infected by the cestode Schistocephalus solidus than slimy sculpins Cottus cognatus (52 v. 23%), and infected C. aleuticus contained more cestodes than did C. cognatus (21 v. 13 per fish). Consumption of sockeye salmon Oncorhynchus nerka eggs (the primary diet item) was lower in fishes with cestodes, and a model based on cestode prevalence and age composition estimated higher rates of infection and parasite-associated mortality in C. aleuticus compared with C. cognatus.
