Scientific Name: Hippoglossus hippoglossus
Atlantic halibut are the largest flatfish in the world, capable of reaching enormous sizes and providing legendary fishing experiences. Our fish identification app helps you identify halibut through their distinctive flatfish characteristics and impressive proportions. These bottom-dwelling giants are among the most prized catches in northern Atlantic waters.
Physical Identification Features
Size & Weight
Halibut can reach exceptional sizes, with mature fish commonly 3-6 feet in length. They can weigh 50-200 pounds, with trophy specimens exceeding 400 pounds and 8 feet in length.
General Appearance
Halibut have the typical flatfish body plan with both eyes on the right side, but are much larger and more elongated than other flounders. The eyed side is dark brown to greenish, while the blind side is white.
Distinguishing Features
Key features include the massive size, both eyes on the right side, straight lateral line, large mouth with sharp teeth, and the ability to reach enormous proportions compared to other flatfish.
Habitat & Distribution
Natural Environment
Halibut inhabit deep, cold waters of the continental shelf and slope, typically at depths of 50-2000 feet. They prefer areas with sandy or muddy bottoms where they can ambush prey.
Geographic Distribution
Found in the North Atlantic Ocean from New Jersey to Greenland on the western side, and from the English Channel to the Barents Sea on the eastern side.
Seasonal Patterns
Halibut spawn in deep water during winter and spring. They make extensive migrations between feeding and spawning areas, with some individuals traveling hundreds of miles.
Behavior & Diet
Feeding Habits
Halibut are aggressive predators that feed on fish, including cod, haddock, and flounder, as well as crustaceans and cephalopods. Large halibut can consume prey up to half their own length.
Activity Patterns
Active throughout the day but often show increased feeding during tidal changes. Halibut are solitary fish that lie buried in sediment, ambushing passing prey with explosive strikes.
Fishing Tips & Techniques
Effective Techniques
Effective methods include deep-water bottom fishing with large baits, drifting with whole fish or large cut baits, and jigging with heavy lures. Use strong tackle and be prepared for long fights.
Recommended Gear
Heavy action rods, large capacity reels with excellent drag, and 50-100 lb test line. Use large circle hooks, heavy sinkers, and strong swivels. Popular baits include whole mackerel, large fillets, and big jigs.
Conservation Status
Atlantic halibut populations have been severely depleted and are slowly recovering. Strict management includes quotas, large minimum sizes, and seasonal closures. Many areas encourage catch and release.
