Description
It is a dark silvery color, with a dark green to black back, and pink or purple on the sides; the outer half of the fins is black. Blackfin ciscoes measure up to 510 mm (21 inches in length). Its preferred habitat is cold lakes at depths of up to 180 metres.
There is great doubt whether the Coregonus nigripinnis was an independent species separate from Coregonus artedi (lake herring) or just an ecomorphotype. as has also been argued for other cisco forms in the Great Lakes area.
