The name namaycush can be traced to journals and writings of employees of the Hudson Bay Company of the 1770s, who described some fishes of the Hudson Bay region.
The scientific name namaycush is an English language rendering of a Native American word for the fish, meaning “dweller in the deep.”
Lake trout (Salvelinus namaycush) are darker than usual.
Lake trout (Salvelinus namaycush) play a key role controlling populations of zooplankton (Daphnia spp.), snails (Lymnaea elodes), and slimy sculpin (Cottus cognatus).
Long-term studies of Toolik Lake, Alaska, project that rising temperatures are likely to eliminate lake trout (Salvelinus namaycush) populations in this lake, with concomitant impacts on the food web.
Other arctic species used locally include Atlantic salmon (Salmo salar), lake trout (Salvelinus namaycush), several species of whitefish, pike, and grayling (Thymallus arcticus).
Two species of salmonids Onchorhynchus mikiss and Christivomer namaycush were introduced in lakes Argentino and Viedma.
