July 12, 2024 — Atlantic sturgeon have been around for 70 million years — predating the dinosaurs. These monumental fish with shark-like fins even survived the Chicxulub asteroid, which caused the great extinction event at the end of the Cretaceous Period.
But the species that once thrived in the Philadelphia region’s waterways has become endangered, threatened by habitat loss, dams, poor water quality and vessel strikes. In the Delaware River, only about 250 estimated sturgeon remain, according to the U.S. Geological Survey.
Sturgeon are also caught in fishing nets and injured by boats during the commercial fishing of other types of fish such as striped bass and summer flounder.
