COSEWIC would like to acknowledge T.A. Dick, R.R. Campbell, N.E. Mandrak, B. Cudmore, J.D. Reist, J. Rice, P. Bentzen and P. Dumont for writing the status report on the Lake Sturgeon Acipenser fulvescens in Canada. This report was first initiated by T.A. Dick, and received funding from the Natural Sciences and Engineering Research Council of Canada, Manitoba Hydro, Fisheries and Oceans Canada (Winnipeg), Environment Canada, Tembec Paper Co. (Pine Falls), Manitoba Model Forest, and Manitoba Conservation. The COSEWIC report review was initially overseen by Dr. Robert Campbell, and later by Dr. Claude Renaud, both Co-chairs of the Freshwater Fishes Species Specialist Subcommittee, with input from members of COSEWIC.
The status report to support the May 2005 COSEWIC re-assessments of the Lake Sturgeon(Acipenser fulvescens) (Western populations, Lake of the Woods- Rainy River populations, Southern Hudson Bay-James Bay populations,Great Lakes-Upper St. Lawrence populations) was not made available following the 2005 assessment.
In November 2006, COSEWIC reassessed again the Lake Sturgeon(Acipenser fulvescens) (Western Hudson Bay populations, Saskatchewan River populations, Nelson River populations, Red-Assiniboine Rivers-Lake Winnipeg populations, Winnipeg River-English River populations, Lake of the Woods-Rainy River populations,Southern Hudson Bay-James Bay populations, Great Lakes-Upper St. Lawrence populations). The status report was then finalized following the COSEWIC 2006 reassessment.
