The RockHopper Fund

Sharks and Big Fish

Continuity is key

The Rockhopper Fund supports research and conservation of sharks & big fish in southern Africa.

We provide the resources for South Africa’s top marine scientists to continue their work – providing the facts and understanding required to solve marine & coastal conservation challenges since 2009.
