Photo of Pacific capelin trawl catch in Cook Inlet Alaska. Capelin are cold water forage fish that play a key role in transferring energy between plankton and top marine predators. Seabirds, and their forage fish prey, serve as practical indicators of change in the marine environment— natural or human induced— and can be readily monitored at sea.

Lake trout with stomach contents in Wrangell St. Elias National Park. Dorsal muscle collection and stomach content analysis are used to evaluate biomagnification of mercury in Lake trout (Salvelinus namaycush). Stomach contents visible below the fish consist primarily of slimy sculpin (Cottus cognatus).
