Hey Steve,
I realize this is an old post but did you ever obtain a permit?
I had a permit between 2004 and 2012 but it was a broker/dealer permit. I doubt the DFG would give a permit to a private individual for display. Let me know if you got the permit. I can still obtain many Carcharhinid sharks (Bull, BTR, Grey Reef, Sandbar, Galapagos, etc.) if you've got the facilities and permit for them.
