Shortnose Sturgeon (Acipenser brevirostrum) Fish Description

Along with the Atlantic sturgeon, the Shortnose Sturgeon is called the “common sturgeon”. These two fishes are distinguished by noting that the Shortnose Sturgeon has a rounder and shorter head compared to the Atlantic sturgeon.

Shortnose Sturgeons have five rows of scutes or bony plates. This fish has a black head and body that is yellowish-brown. Shortnose Sturgeons have white or yellow bellies; they have a prominent snout pointing forward and with four fleshy, whisker-like projections or barbels.

 

Diet and Size

Shortnose Sturgeons use their barbels to forage for food in the muddy and sandy bottom areas of rivers. They use their vacuum-like mouths to suck their food. Shortnose Sturgeons typically eat invertebrates like mollusks, crustaceans, mollusks, and insects. They also feast on small benthic fishes, bivalves, polychaetes, and gastropods.

Shortnose Sturgeons measure up to 54 inches and weigh up to 60 pounds. They can live up to 30 years on average; some were reported to have reached almost 70 years old. They develop and mature slowly.
