Lake trout from Chandler Lake
Detailed Description
A field biologist landed this large 7 kg (15 lb) lake trout (Salvelinus namaycush) on the shore of Chandler Lake, Gates of the Arctic National Park. The lake trout was collected as part of a study investigating the biomagnification of mercury through lake food webs. Tissues from the lake trout will be used to determine its mercury concentration, diet, and age.

Mercury concentrations in fish likely reflect different energy sources in lake food webs. Species, populations, or individuals may contain higher and variable concentrations of mercury, which may relate directly to prey mercury content, diets of fish, and fish foraging strategies.
