What kinds of fish and wildlife live in Great Slave Lake?

Great Slave Lake supports a rich aquatic ecosystem that includes lake trout, northern pike, Arctic grayling, and inconnu, making it a top destination for northern freshwater fishing. The deep, cold waters favour large, slow-growing trout populations and other coldwater species that are sought by anglers and researchers alike. Shorelines, islands, and surrounding wetlands provide habitat for migratory birds, waterfowl, and mammals such as moose, wolves, and occasionally polar-bearing-range visitors at far northern reaches. Seasonal patterns—ice cover in winter and open water in summer—drive migration and feeding cycles for both fish and birds. Conservation efforts and local fisheries management aim to balance recreation and subsistence uses with long-term ecosystem health.
