Note: These
data were used to quantify the indirect reliance of piscivores on zoobenthos
(i.e., piscivores consuming zoobenthivorous prey fishes).
†Estimates of zoobenthivory
are based on only young-of-the-year and juvenile fishes.
‡Estimates of zoobenthivory from data in Vander Zanden and Rasmussen
(1996).
