Common Fishing Lures and Baits
Yellowfin Tuna can be caught by trolling with rubber skirted lures or natural baits.

Bait fisherman often chum, called "chunking", when fishing for tuna. Chunking uses pieces of fish tossed into the water while drifting or anchored to attract tuna close to the fishing vessel. Anglers then drift a piece of fish with a hook in it, hoping for a bite.
