Saint Lawrence River

The Lake Sturgeon (Acipenser fulvescens) population of the St Lawrence River has been followed closely for decades. The commercial fishing of this species in the River is the most important in North America. The Lake Sturgeon is currently being considered for listing under the federal Species at Risk Act.

A number of reproduction sites have been found in the River and its tributaries, including a major site on the Des Prairies River.

In 1996, MILIEU completed a study aiming at finding out whether Lake Sturgeon used the Cascades-North sector of Lake Saint Louis, just downstream of the Pointe-des-Cascades regulating station.
