Wikipedia Abstract

The bloater (Coregonus hoyi) is a species or form of freshwater whitefish in the family Salmonidae. It is a silvery-coloured herring-like fish, 25.5 centimetres (10.0 in) long. It is found in most of the Great Lakes and in Lake Nipigon, where it inhabits underwater slopes. This fish is not to be confused with the extinct deepwater cisco (Coregonus johannae), a large fish that shared a common name with the bloater.
