Tiger sharks and other large sharks are top predators that help maintain the health of marine ecosystems. But sharks populations are in trouble globally. The decline of the shark population produces unexpected and devastating consequences for the food web.
Research initiated by the PEW Shark Campaign has shown correlations between the balance of shark population and the fish stock of commercially important fish species such as tunas and jacks. The impact of those researches is of special importance for understanding how actions should be taken to protect the shark species and the health of the oceans.
