COSEWIC Status Reports

COSEWIC Assessment and Update Status Report on the Lake Sturgeon (Acipenser fulvescens) in Canada

The sturgeon family (Acipenseridae) contains 24 species, five of which are found in Canadian waters. Four of these are anadromous (spending part of the life cycle in freshwater and part in marine environments) and one, the lake sturgeon, is found only in fresh water. This species is one of Canada’s largest freshwater fishes with an extended snout, ventral mouth with four pendulous barbels, and a body covering of hard scutes and smaller denticles, rather than scales. This species reaches an age in excess of 100 years, lengths of up to 3 m and weights up to 180 kg.
