Abstract
⺠Total mercury concentrations ([THg]) were measured in Arctic charr from a single lake in the Canadian high Arctic. ⺠Anadromous Arctic charr had a significantly lower mean [THg] (64 μg/kg ww) than the non-anadromous fish (117 μg/kg ww). ⺠Length-at-age (i.e., average somatic growth rate) was not related to mean [THg] when same-age groups were compared. ⺠Prey resource use, determined by δ13C and δ15N isotopes and gut contents, was similar among fast- and slow-growing fish. ⺠Maturity state was not related to [THg], but the slow-growing group had a greater proportion of current year spawners.
