--------------- Northern Longnose Sucker (fish) ---------------------

Global Range Comments: The most widespread sucker in northern North America. Throughout most of Alaska and Canada, south to New England, West Virginia-Maryland, northern Ohio, northern Indiana, Minnesota, Nebraska, eastern Colorado, Idaho, and Washington. Also in northeastern Asia. Introduced in upper Colorado River drainage, Wyoming and Colorado.

Life History

Basic Description: A fish (sucker).

Habitat Comments: Cold clear waters; bottom dweller in lakes and tributary streams; to depth of 600 ft in Great Lakes. Also in brackish water near mouths of Arctic streams. Often spawns in flowing shallow stream water over gravel; otherwise in lakes. Eggs sink and stick to bottom. Young stay in gravel 1-2 weeks before emerging.

Degree of Threat: Unthreatened on a range-wide basis, although it may be threatened in minor portions of the range.

Threats: Threatened in Lake Michigan due to deteriorating water quality and ecological imbalance caused  by introductions of non-native fishes (Herkert1992).

Fragility: tough (e.g.. redwoods)
