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
Scripps.
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.
