Predator-size prey-size relationships for piscivorous fishes. We use these data to compare cannibal to non-canibal prey, predator-size prey-size relationships among Northwest Atlantic fishes (part of these data are available at Ecological Archives E086-135; http://esapubs.org/archive/ecol/E086/135/), western Pacific large pelagics and for 14 populations of striped bass.
