General Habitat and Food Preferences The Yellowfin Tuna is an oceanic species that prefers deep, wide open waters.

They are a schooling fish, often mixed with other tuna, that feed primarily on shrimps, squids, and fishes.
Did You Know? The Yellowfin Tuna is very loyal to its school and they will do all they can to protect each other.
Common 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.
Typical Sizes Caught Yellowfin Tuna are commonly caught in the range of 32 to 43 inches in length (25 to 60 pounds) by anglers.
