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

They are a schooling fish, often mixed with other tuna.

Common Lures and Baits Bigeye 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 Bigeye Tuna are commonly caught in the range of 100 to 200 pounds by anglers.
