Our film Sharks: Stewards of the Reef also examines finning and the  
removal of threats to coral reefs systems, as discussed by Dr Enric  
Sala of SIO, and featured in his 2005 PNAS article with Bascompte et  
al.  This subject specifically examines the reef shark coral reef  
While this documentary lacks the drama and entertainment of  
Sharkwater, it is based on science and examines overfishing and  
marine management.

The trailer is on www.sharkstewards.com.

This thread is very interesting to me, but Im going to have to sign  
off for the next 3 months.  I'll be working on a film in Cocos,  
Galapagos, easter Island and Chile, and hope to have some footage and  
develop a short on the overfishing of sharks.
