Population Structure and Genetic Diversity of Lake Sturgeon (Acipenser fulvescens) in Canada: Evaluation of Designatable Units for Conservation
The lake sturgeon (Acipenser fulvescens), is a species with considerable ecological, social and economic value. Unfortunately, over-exploitation and habitat alteration have led to the collapse of lake sturgeon fisheries across North America. Based on conservation concerns, the Committee on the Statu...
