Summary
Adult walleye (10 females and 10 males) were caught in Fox River (Wisconsin) during April 2014. Total length, weight, and age were determined for each of the walleye. Whole-fish homogenates were prepared during 2017. Lipid concentration and polychlorinated biphenyl (PCB) congener concentrations were determined in each of the homogenates during 2017-2018. For each sample, PCB congener concentrations were summed to yield total PCB concentration. All lipid and PCB congener terminations were made at the University of Michigan School of Public Health in Ann Arbor, Michigan.

Whole-fish homogenates were prepared during 2017. Lipid concentration and polychlorinated biphenyl (PCB) congener concentrations were determined in each of the homogenates during 2017-2018. For each sample, PCB congener concentrations were summed to yield total PCB concentration. All lipid and PCB congener terminations were made at the University of Michigan School of Public Health in Ann Arbor, Michigan.
The data were collected to: (1) quantify the difference in whole-fish PCB concentrations between the sexes of adult walleye from the Fox River population, (2) determine whether a PCB hot spot effect was evident in the Fox River walleye PCB data, and (3) determine whether PCB congener distributions significantly varied between the sexes of Fox River walleye.
