Inconnu is a species of freshwater whitefish in the family Salmonidae. The Inconnu is now considered extinct in the wild, but survives in cultured stocks.
How To Identify:
The fish has a large mouth with a protruding lower jaw and a high and pointed dorsal fin. It is generally silver in color with a green, blue or brown back. The meat is white, flaky and somewhat oily. An adult fish weighs from 14 to 25 kilograms (31 to 55 lb). The fish eat plankton for their first year of life and then become predators of smaller fish.
How To Catch:
This bottom feeder likes river drainages. Local anglers pursue Inconnu at the mouth of tributary streams and in back eddies. Inconnu are sometimes fished with gold and silver spoons about 4 cm (1.5 in.) long. Some anglers like to drift fish with rubber tailed jigs. Inconnu are easier to find when the rivers and lakes are their lowest in early spring and late fall. If you plan to release this fish, handle it very gently as its scales come off easily.
This member of the salmon family is found in of Alaska from the Kuskokwim River north, throughout the Yukon River into Canada as well as the MacKenzie River and Great Bear and Great Slave Lakes in Canada's Northwest Territories as far as the Anderson River near Cape Bathurst, and in isolated areas of extreme northern British Columbia. On the Asian side, it occurs westward as far as the White Sea, and an isolated population inhabits the Caspian Sea. In coastal areas this species is anadromous, but in many inland lakes it has become strictly a freshwater fish.
