Stapleton et al. [138] found that burbot (Lota lota) from Grand Traverse Bay had higher levels of toxaphene than lake trout, followed by salmon > sculpin > lake whitefish (Prosopium cylindraceum). Mean concentrations of toxaphene in lake trout from GTB were within the range (means of 350-810 ng/g wet wt) observed by Glassmeyer et al. [49] for three sampling locations in Lake Michigan. 

In Lake Siskiwit both piscivores (northern pike) and planktivores (lake whitefish (Coregonus clupeaformis), pigmy whitefish (Prosopium coulter)) had very similar total toxaphene concentrations to lake trout, while yellow perch (Percopsis omiscomaycus) had much higher concentrations of toxaphene than lake trout (Table 11) [74]. Indeed one sample of yellow perch had 1050 ng/g ww total toxaphene.
