There is a concern in Fiji that some Asian traders are using local fishermen to obtain fins.
The Beqa Adventure Divers director, Mike Neuman, says sharks play important roles in local marine ecosystems and are worth more alive than dead.
Mr Neuman says there have been instances where local fishermen are targetting sharks specifically for their fins.
He says the fisherman are approached by Asian groups linked to the beche de mer or sea cucumber trade.
"And now these same people have started telling the fishermen, ok, next time, I come, give me some shark fins, I will pay you money and the same fins are going in the same shipment to Asia."
He says 99.9 percent of these sharks are exported.
Hawaii, the Northern Marianas and Guam have now banned shark finning, and the Marshall Islands has issued a moratorium on shark fishing
In 2009, Palau created its first shark sanctuary.
