Atlantic Halibut
Hippoglossus hippoglossus
Atlantic halibut is the largest flatfish in the North Atlantic, living mostly on or near the seafloor. It is a powerful ambush predator and prized food fish, but many stocks have been heavily depleted and are tightly managed in much of its range.

Identification points
- Both eyes are on the right side of the head in most individuals.
- Body is very elongated for a flatfish, with a narrow tail section and broad, diamond-shaped body.
- Upper side is usually dark brown to olive with a white blind side underneath.
Habitat
Cold North Atlantic continental shelf and slope waters, usually over sand, gravel, or muddy bottoms from shallow banks to several hundred meters deep; adults often lie partly buried on the seabed.
Bait notes
Best on large natural baits: whole or cut herring, mackerel, squid strips, and fish heads. Big soft plastics and jigs can work where legal, but bait is usually more consistent for trophy fish.
Behavior
A slow-moving bottom ambush predator that feeds on fish such as cod, haddock, capelin, and herring, plus squid and crustaceans. Larger fish often move deeper and can make strong runs once hooked.
Caution
Check local regulations carefully; Atlantic halibut are heavily regulated or closed in many areas due to stock status. Large individuals can accumulate mercury and other contaminants, so follow local consumption advisories.
Fishing notes
Fish near bottom with heavy tackle, strong leaders, and enough lead to hold in current. Drift or slow-troll over known banks and dropoffs, keeping bait close to bottom; strikes can be subtle before the fish loads up.
