Over three generations, the distribution and abundance of mature individuals has declined dramatically, largely as the result of harvesting and dams, which have not ceased. Occurrence Saskatchewan, Manitoba Status history The species was considered a single unit and designated Not at Risk in April 1986.

Assessment Summary – April 2017 Common name Lake Sturgeon - Saskatchewan-Nelson River populations Scientific name Acipenser fulvescens Status Endangered Reason for designation This is one of the largest, longest-lived, freshwater fish species in Canada and has special significance to Indigenous Peoples. Formerly assessed as five separate designatable units, recent genetic evidence indicates that those populations should be treated as a single unit. Harvesting and dams were the main reasons for historical declines. Although some populations appear to be recovering, this species is not yet clearly secure. Occurrence Alberta, Saskatchewan, Manitoba, Ontario Status history The species was considered a single unit and designated Not at Risk in April 1986. When the species was split into separate units in May 2005, the "Western populations" unit was designated Endangered. In November 2006, the Western populations unit was split into five separate populations. In April 2017, the Winnipeg - English River, Red-Assiniboine Rivers - Lake Winnipeg, Saskatchewan River, Nelson River, and Lake of the Woods - Rainy River populations were considered a single unit and this 'Saskatchewan - Nelson River populations' unit was designated Endangered. iii Assessment Summary – April 2017 Common name Lake Sturgeon - Southern Hudson Bay – James Bay populations Scientific name Acipenser fulvescens Status Special Concern Reason for designation This is one of the largest, longest-lived, freshwater fish species in Canada and has special significance to Indigenous Peoples. Some populations are impacted by harvesting and dams, some populations exist in pristine environments, and there are likely many populations yet to be discovered in this remote area. If not mitigated, future development may negatively impact the species. Occurrence Manitoba, Ontario, Quebec Status history The species was considered a single unit and designated Not at Risk in April 1986. When the species was split into separate units in May 2005, the "Southern Hudson Bay - James Bay populations" unit was designated Special Concern. Status re-examined and confirmed in November 2006. Status re-examined and confirmed in April 2017. Assessment Summary – April 2017 Common name Lake Sturgeon - Great Lakes – Upper St. Lawrence populations Scientific name Acipenser fulvescens Status Threatened Reason for designation This is one of the largest, longest-lived, freshwater fish species in Canada and has special significance to Indigenous Peoples. The main reasons for historical declines in most populations, harvesting and dams, are clearly reversible and understood, but have not ceased in all populations. Some populations appear not to have been severely impacted and some populations appear to be recovering but are not yet secure. Occurrence Ontario, Quebec Status history The species was considered a single unit and designated Not at Risk in April 1986.

It is one of Canada’s largest freshwater fishes. Lake Sturgeon has a pointed snout, ventral protrusible mouth, four barbels in front of the mouth, five rows of bony scutes, and a heterocercal tail. Special Significance The Lake Sturgeon has a rich historical significance to First Nations peoples and was also commercially harvested across much of the species’ range between the late-1800s and mid-1900s. The St. Lawrence River in Quebec supports the only remaining commercial fishery. Aboriginal fisheries are ongoing. Caviar, made from Lake Sturgeon eggs, is still highly prized. Lake Sturgeon is also sought by trophy anglers (where permitted; predominantly catch-and-release) in many locations. Distribution The Canadian range stretches from the North and South Saskatchewan rivers in Alberta in the west, to the St. Lawrence River estuary in the east, and from various rivers that empty into Hudson Bay in the north to several boundary waters (e.g., Rainy River, Great Lakes) in the south. Designatable Units Based on the national freshwater biogeographic zones used by COSEWIC and supplemental genetic information, four designatable units were identified: DU1 - Western Hudson Bay; DU2 - Saskatchewan-Nelson River; DU3 - Southern Hudson Bay-James Bay; DU4 - Great Lakes-Upper St. Lawrence. v Habitat The range of the Lake Sturgeon spans four freshwater biogeographic zones and six terrestrial ecozones. The species occupies a wide variety of aquatic ecosystem types (e.g., stepped-gradient Boreal Shield rivers, low-gradient meandering Prairie rivers, low gradient Hudson lowland rivers, Great Lakes and associated tributaries). Habitat Requirements Lake Sturgeon requires a variety of habitats to complete its lifecycle, and the species has evolved to exploit typical upstream to downstream hydraulic and substrate gradients. Spawning habitat is typically characterized by fast-moving water found at the base of falls, rapids, or dams. Hatch is contingent on aeration by flowing water, after which larvae apparently require gravel substrate in which to bury and remain while development continues. Once the yolk sac is absorbed, larvae drift downstream via water currents. Habitat requirements at the age-0 stage are not well understood, but may not be as strict as previously assumed. Aside from the requirement of adequate benthic prey items, the habitat requirements for middle to later life stages (juveniles and adults) are not particularly narrow. Habitat Trends

  • Life History and Population Dynamics of Lake Sturgeon
    LIFE HISTORY AND POPULATION DYNAMICS OF LAKE STURGEON, Acipenser fulvescens, IN THE MUSKEGON RIVER, MICHIGAN by Paul Joseph Vecsei (Under the direction of Douglas L. Peterson) ABSTRACT The lake sturgeon was once abundant throughout Lake Michigan with an estimated 11 million fish prior to human exploitation. By the early 1900s, however, most populations had been decimated by severe over-fishing and habitat degradation. Despite recent interests in restoring the species in Lake Michigan, little is known about the current status of remnant populations. The primary objectives of this study were to estimate annual spawning stock abundance and to identify potential spawning habitat for lake sturgeon on the Muskegon River, Michigan. To capture adult lake sturgeon, I used large-mesh, bottom-set gill nets deployed at the mouth of the Muskegon River from mid- March through May, 2002-2005. Radio telemetry was used to monitor seasonal movements and to identify likely spawning habitats. Sampling for larval lake sturgeon was conducted in May of each year using D-frame drift nets anchored in the mainstream of the river channel. During the 4 years of the study, I expended more than 5000 gill-net hours and captured 59 individual adult lake sturgeon. Larval lake sturgeon were captured in 2 years, suggesting that at least some natural reproduction still occurs. Habitat analysis revealed that the lower Muskegon River likely contains extensive reaches of potential spawning habitat for lake sturgeon. INDEX WORDS: Biology, population dynamics, habitat, lake

Alternatively, the Center requests that the USFWS define and list distinct population segments of lake sturgeon in the U.S. as threatened or endangered. Lake sturgeon populations in Minnesota, Lake Superior, Missouri River, Ohio River, Arkansas-White River and lower Mississippi River may warrant endangered status. Lake sturgeon populations in Lake Michigan and the upper Mississippi River basin may warrant threatened status. Lake sturgeon in the central and eastern Great Lakes (Lake Huron, Lake Erie, Lake Ontario and the St. Lawrence River basin) seem to be part of a larger population that is more widespread.
