COSEWIC assessment and status report on the shortnose sturgeon, Acipenser brevirostrum, in Canada . : CW69-14/427-2015E-PDF
“This large-bodied, slow-growing, late-maturing fish is found only in a single river estuary system in Canada where spawning fish aggregate in a single known location. Although there are no imminent threats toward the species, its limited distribution makes the species vulnerable to becoming Threatened if conditions thought to negatively impact it (variable flow patterns, pollution, bycatch in commercial fisheries, and poaching) are not managed effectively. Designated Special Concern in April 1980. Status re-examined and confirmed in May 2005 and in May 2015"--Assessment summary, p. iii.
