Im planning on going to the marathon humps to jig for some tuna , and while im at it , get a nice chunk of fresh tuna and throw it down for shark.I was also thinking about using an injured up small live tuna better ?! Have any tips and advice for me ?
Thanks, hope to hear from you guys soon ! 
I know that jigging is very productive and jigging at the hump produces BFT. I think the local expert on the Hump would be Will and I'm sure he will chime in soon.

The humps off Islamorada and Marathon are known for attracting big Tigers,Makos and even an occasional Great White but most have been caught during the amberjack season late Febrauary to April but im sure the abundance of pelagic species there attract sharks year round.Drop half a bonita,blackfin tuna or cuda down and HOLD ON!!
