Overfishing, habitat degradation from pollution, increasing river use, and management including the construction of dams and barrages, are the principal threats.
Porbeagle sharks are listed as vulnerable by the International Union for Conservation of Nature because they were overfished beginning in the 1960s. By around 2001, estimates suggested the species ...
