Wikipedia Abstract

Lake trout (Salvelinus namaycush) is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish.

Invasive Species

Salvelinus namaycush is a freshwater fish of the trout family, found primarily in lakes and large rivers worldwide. The distribution is broad due to the sport fishing industry and the demand for Salvelinus namaycush. In many of the introduced locations Salvelinus namaycush is an invasive species and reduces native biodiversity through competition and predation of endemic species. There have been some successful attempts to control Salvelinus namaycush using gillnetting and trapping.
