Lake Sturgeon Description

Alberta Lake Sturgeon are the largest game fish in Alberta and although they are currently protected throughout the province, population recovery has occurred in three major river systems since 1940. Lake Sturgeon are commonly caught in the North Saskatchewan, South Saskatchewan and Red Deer river systems by experienced anglers in all slot sizes. They routinely travel over 100 kilometres between the Alberta and Saskatchewan border through the North and South Saskatchewan river systems. They can live over 100 years old and reach weights over 100 pounds. Catch and release rules still apply province wide, while biologists are currently assessing their listed protected status.
