Imagine prehistoric creatures, up to 14 feet long, swimming in creeks
and streams along the densely populated East Coast of the U.S. Surprisingly,
such animals still exist, and NOAA and partner scientists are using innovative
techniques to track them through Chesapeake Bay tributaries.
Sturgeon appeared in the fossil record approximately 200 million years
ago, before the evolution of some dinosaurs, including Tyrannosaurus rex.
Atlantic sturgeon, ranging from Canada to Florida, were subjected to a robust
commercial fishery beginning in 1880. The fishery from Maine to Florida
continued through 1998, severely depleting, and in some cases destroying, their
populations.
As part of a range-wide effort to conserve the species and protect
future generations, scientists with NOAA FISHERIES, THE U.S. NAVY, AND PRIVATE
FIRM CHESAPEAKE SCIENTIFIC are using tagging and genetic technology to
understand how Atlantic sturgeon move through tributaries of the Chesapeake as
they spawn. Learn more about their ongoing collaboration in this video.
