In‐stream population structuring of Lake Sturgeon in Northern Manitoba, Canada
Abstract The Lake Sturgeon is a long‐lived, late‐maturing fish that declined significantly in abundance over the past 150 years. Since the 1990s, stocking has been used to recover numerous Lake Sturgeon populations across North America. Ill‐informed genetic mixing among populations can have unintend...
