Longjaw Cisco
Coregonus alpenae
The longjaw cisco (Coregonus alpenae) was a deep-water cisco or chub, usually caught at depths of 100 metres (328 ft) or more from Lakes Huron, Michigan, and Erie. Its Latin name was derived from Alpena, a city in Michigan. Silver colored and growing to a maximum length of about 30 centimeters (12 inches) long, the extinction of longjaw cisco was a result of overfishing, pollution of the Great Lakes and the disruption of Great Lakes food chains after the introduction of the sea lamprey.
The systematics of the group of fishes called "ciscoes" is complicated and scientists now generally believe that the longjaw cisco was not a separate species, but a distinctive population of large-bodied individuals of shortjaw cisco (Coregonus zenithicus).
