| Description | This article was published in the Journal of Freshwater Ecology, Vol. 17, No. 4, pp. 621-633, December 2002. The article reports differences in mercury (Hg) concentrations among Lake Whatcom fish occupying different trophic levels. The highest Hg concentrations were found in predaceous smallmouth bass and large yellow perch (means of 0.49 and 0.20 ug/g, respectively) followed by omnivorous brown bullhead (0.16 ug/g), zooplanktivorous kokanee (0.12 ug/g), benthivorous pumpkinseed (0.10 ug/g), and herbi-detritivorous signal crayfish (0.10 ug/g). Predaceous cutthroat trout had low mean Hg (0.07 ug/g), possibly due to the small size of specimens analyzed. The much larger bass and perch showed a strong positive relationship between length and Hg, illustrating the magnification of Hg due to trophic position. |
