Habitat Trouble for Shortnose Sturgeon in Northeastern States

from the National Fish Habitat Partnership's 2015 Through a Fish's Eye Report


The Shortnose Sturgeon (Acipenser brevirostrum), the smallest of the three sturgeon species that occur in the eastern United States, requires clean rock or rubble above the head of tide for spawning. It has suffered from the construction of dams in the region. This species migrates upriver from lower reaches of river systems or from upper estuary areas to spawn, but has been blocked from reaching spawning areas by dams. Other spawning habitat has been impaired by water flow changes from water withdrawals and dam operations, particularly peaking power operations. Sturgeon species, in general, are very sensitive to changes from the natural water flow conditions.
