Abstract
In Aug., 1963 electrofishing gear was used to remove 1,968 Esox lucius from three connecting trout streams. Stomach contents of 91 pike from a mile-long census zone (2.2 surface acres) of the Mecan River were analyzed. Mean total length of these pike was 13.5 inches. Food was present in 24 stomachs. Trout constituted 54% of the food items present. Salmo gairdneri were eaten more often than Salmo trutta despite a large preponderance of S. trutta in the census zone (2,326 S. trutta to 422 S. gairdneri). Scars inflicted by pike were found on 9% of 308 S. trutta examined in the census zone, but 37% of 43 S. gairdneri examined were scarred.This publication has 0 references indexed in Scilit:
