Introduction
The Shortnose Sturgeon (Acipenser brevirostrum) is a fascinating species from the Acipenseridae family. Known for its armored, elongated body, this fascinating sturgeon species lives primarily in the eastern coastal rivers of North America.
Conservation Status
The Shortnose Sturgeon is currently classified as an endangered species by the United States Federal Government. Extensive conservation efforts have been undertaken to halt the decline of their populations, such as habitat protection, stocking programs, and restrictive fishing regulations.

Distribution
Shortnose Sturgeons are mostly found in the eastern coastal rivers of North America, from Canada’s Saint John River to Florida’s St. Johns River. They engage in short-distance migrations for feeding and spawning purposes. Their movements are impacted by water temperature, river flow, and availability of food resources.
Habitats
They are usually found in freshwater rivers, but can tolerate a wide range of salinities. The depth range of shortnose sturgeons varies with their life stages, generally staying near the bottom. Though they can survive in a wide range of temperatures, they prefer cooler temperatures.
When and Where to See
Shortnose Sturgeons are more active during the cooler months and more likely to head upstream. They are usually more active during the night and at dawn or dusk.
Best Fishing Locations
Though strongly discouraged due to their endangered status, if you are interested in observing Shortnose Sturgeons, some of the rivers where they can be found include:
- Saint John River, Canada
- Hudson River, New York
- Delaware River, Pennsylvania/New Jersey/Delaware
- Connecticut River, Vermont
- Kennebec River, Maine
- Savannah River, Georgia/South Carolina
Identification Guide
Shortnose Sturgeons typically have an armor-plated body that is grayish-blue or olive-green in color. They can be recognized by their short conical snout and slightly upturned mouth. They are smaller than most other sturgeons
Culinary
Due to their endangered status, the harvesting of Shortnose Sturgeons for culinary purposes is illegal. Hence, information related to taste profile, nutritional information, and recipes is not applicable.
Additional Information
Shortnose Sturgeons exhibit strong homing behavior for spawning. They mainly consume insects, crustaceans, and tiny fish. Their natural predators include larger fish, birds, and marine mammals. Human-induced threats consist of pollution, habitat loss, dams, and overfishing. Despite their current status, Shortnose Sturgeons are an important part of the ecosystem and play significant roles in local cultures and histories, particularly in Native American traditions.
