The principal investigator of this study,  Dr. Enric Sala of SIO is  
featured in our film Sharks: Stewards of the Reef where he brings  
this study to light.  As reported in his April 2005  Study published  
in PNAS, Dr. Sala et al correlates the cascade effects of removing  
apex predators such as sharks to the overall health of the marine  
system, particularly coral.

One of the most striking products of the study is a stark picture of  
human impacts on marine ecosystems and the consequences of targeted  
fishing. In the Caribbean, overfishing of sharks triggers a domino  
effect of changes in abundance that carries down to several fish  
species and contributes to the overall degradation of the reef  
ecosystem. Overfishing species randomly, the study shows, is not  
likely to cause these cascading effects.

"It appears that ecosystems such as Caribbean coral reefs need sharks  
to ensure the stability of the entire system," said Sala, deputy  
director of the Center for Marine Biodiversity and Conservation at  

This 30 minute film, also features Shark Conservationists Sonja  
Fordham, Peter Knights and examines threats to sharks, including  
shark finning, the importance of sharks ecologically and how we can  
support marine protected ares for sharks and a healthy ocean.  We are  
screening at the Monterey Bay Aquarium this month.
