Green sea urchins were the most abundant food species (62% by weight) in American plaice (all female) collected from an area in eastern Newfoundland where sandy bottom abuts urchin dominated bedrock. Of secondary importance were capelin (12.9% by weight), which were spawning in the area when the samples were obtained. The results suggest that American plaice may be important predators of urchins in such habitats.
