State Rarity Rank: S1
A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State.

Global Rarity Rank: G3
A Global Rarity Rank of G3 means: Either rare and local throughout its range (21 to 100 occurrences), or found locally (even abundantly at some of its locations) in a restricted range (e.g. a physiographic region), or vulnerable to extinction throughout its range because of other factors.

Did you know?
The Atlantic sturgeon is the largest of the three sturgeons found in New York State. They can live 30 to 60 years, grow 6 to 14 feet in length, and can weigh 200 pounds or more. Individuals weighing up to 800 pounds and measuring 14 feet in length have been documented and even larger fish have been reported (Smith 1985).

State Ranking Justification [-]
This anadromous species is found in the Hudson River north to the dam in Troy. It has suffered substantial declines from historical numbers, due to overfishing, and a harvest moratorium was imposed in 1996. Although the Hudson River population is one of two populations that are presumed to be the healthiest in the United States (Atlantic Sturgeon Status Review Team 2007), the stock is at its lowest level in the past 120 years (New York State Department of Environmental Conservation 2006), and the species is a candidate for federal listing.
