I'm down here on vacation for the week and would like to catch a few fish with my son. What should I be targeting with the water being colder? What bait should I use? I would also like to try and catch a shark or two. I don't have a kayak so I can't get the bait out all that far. Normally I walk the bait out as far as I can but I'm not sure I'm willing to do that with the water and air temp. Thanks!
