Live bait for shark and spanish

I’m going shark fishing next weekend on the broad river pier. Thinking of trying live lining. What is the best bait to use for shark out of mullet, menhaden, whiting or croaker? Is it better to free line the fish or have it on the bottom? Also what is the best way to hook the baitfish without it dying quickly?

Best vait is whats around, mullet, menhadden, if there is none around whiting/croaker. The bottom bait will sit still, free line you have to watch your bait so it doesnt swim some where bad. Hook through nose for natural swimmind, top of back or tail to swim down and bottom of tail to swim up. I think they balloon baits there mostly. Good luck and let me know what the fishing is like.
