Management Plan for the Green Sturgeon (Acipenser medirostris) in Canada

The Green Sturgeon (Acipenser medirostris) is an anadromous fish that was originally assessed in November 2004 as ‘special concern’ by the Committee for the Status of Endangered Wildlife in Canada (COSEWIC), and recently reassessed under the same status in November 2013. Green Sturgeon was listed as a species of Special Concern under the Species at Risk Act (SARA) in September 2006 and is currently listed as such.

Green Sturgeon are thought to represent an early evolutionary offshoot from primitive bony fish, dating back about 200 million years. These large fish can reach a maximum size of 2.3 metres and 159 kg (Scott and Crossman 1973). The ventral surface is white with a dark olive stripe extending down the middle of the belly, often terminating anterior to the pectoral fins (Scott and Crossman 1973). Green Sturgeon are found in the shallower waters of the continental shelf (i.e., less than 110 metres) along the western coast of North America, from Mexico to southeastern Alaska. This range overlaps with that of White Sturgeon (Acipenser transmontanus), thus it is important to distinguish between the two species as they are generally similar in appearance.
