| males exceed females in pcb concentrations of cisco (coregonus artedi) from lake superior. | we determined whole-fish polychlorinated biphenyl (pcb) concentrations of 25 male and 25 female age-7 ciscoes (coregonus artedi) captured from a spawning aggregation in thunder bay, lake superior, during november 2010. we also determined pcb concentrations in the ovaries and somatic tissue of five additional female ciscoes (ages 5-22). all 55 of these ciscoes were in ripe or nearly ripe condition. bioenergetics modeling was used to determine the contribution of the growth dilution effect toward ... | 2014 | 24954559 |
