General Habitat and Food Preferences

They are a schooling fish that feed primarily on fishes, shrimps, and squids.
General Description
The Atlantic Bluefin Tuna is a metallic blue on top with a shimmering silver-white underneath.
Did You Know?
Atlantic Bluefin Tuna are warm-blooded, a rare trait among fish, and are thus able to adjust their body temperature, keeping their body temperatures higher than the surrounding water, which is why they are so well adapted to cooler ocean waters.
Common Fishing Lures and Baits
Atlantic Bluefin 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
Atlantic Bluefin Tuna are commonly caught in the range of 27 to 80 inches in length (60 to 300 pounds) by anglers.
