The Atlantic whitefish (Coregonus huntsmani) is a coregonine fish inhabiting some freshwater lakes within Nova Scotia, Canada. It is known to survive only in the Petite Rivière watershed as landlocked populations. Earlier it was also found in the Tusket and Annis rivers of Nova Scotia. Those populations were anadromous, migrating to the estuary to feed while breeding in freshwater.
C. huntsmani was originally designated Coregonus canadensis, but the species name was changed in 1987. Other common names that C. huntsmani is known by are Acadian whitefish and sault whitefish. The species was designated as an endangered species by the World Conservation Union in 1986 and vulnerable in 1996. Nova Scotia prohibited the taking of Atlantic whitefish under the Canadian Fisheries Act.
The Atlantic whitefish has a typical salmonid body shape and is silvery on the sides and underside with a dark blue to dark green back. The landlocked populations feed on insects and small fish. The reproduction of Atlantic whitefish in nature has not been observed.
The narrowly endemic Atlantic whitefish is genetically distinct from the lake whitefish (Coregonus clupeaformis) and the cisco (Coregonus artedi), which both are widespread across much of continental North America.
