Introduction
The Atlantic Wolffish (Anarhichas lupus), also known as the Seawolf, Atlantic catfish, ocean catfish or wolf eel in North America, is a fascinating marine fish known for its unique physical features and behavior. Belonging to the family Anarhichadidae, this species is an intriguing part of the oceanic ecosystem.
Conservation Status
The Atlantic Wolffish is currently listed as ‘Near Threatened’ according to the IUCN Red List. Conservation efforts are in progress, focusing on population monitoring and controlling excessive fishing to ensure that this unique species does not reach endangered status.
Statistics
| Length(Average) | Length(Range) | Weight(Average) | Weight(Range) | Average Lifespan |
|---|---|---|---|---|
| 100 cm | 30-200 cm | 15 kg | 5-25 kg | Up to 25 years |
Distribution
The Atlantic Wolffish is distributed across the northern Atlantic Ocean. It is found in the seas of Canada, Greenland, Norway, and parts of the United States.
Migration Patterns
Atlantic Wolffish are non-migratory. They remain in their same rocky seabed habitats throughout their lives.
Habitats
- Water Type: Saltwater
- Depth Range: Usually found between 20 and 500 meters
- Temperature Range: Prefer cold temperatures ranging from -1 to 11 degrees Celsius
When and Where to See
The Atlantic Wolffish, due to its preference for colder waters, is usually seen during the colder months. They remain near the seabed during the day, and are therefore more observable during night-time explorations.
Best Fishing Locations and Tips
Some of the best fishing locations for the Atlantic Wolffish include the coasts of Norway, Canada, and northeastern United States. While Atlantic Wolffish are not usually caught for sport, they sometimes bite on lobster baits in traps. If you wish to catch one, the best method would be deep sea bottom fishing with strong gear, and using heavy baits such as cut fish, squid or large worm.
Identification Guide
The Atlantic Wolffish is primarily characterized by its elongated body, large mouth filled with strong canine teeth, and it has bulging eyes. They vary in color from purplish-brown to blue-grey.
Culinary Significance
The meat of the Atlantic Wolffish, known for its mild, sweet taste, is a popular food source in some areas. Some special recipes include baked Wolffish with lemon and herbs, or pan-seared Wolffish.
Additional Information
Atlantic Wolffish primarily feed on hard-shelled invertebrates. Human-induced threats, such as overfishing and destruction of habitats from trawling, pose significant risks. The Atlantic Wolffish does not have significant cultural or historical significance, though it is commonly depicted in art and photography due to its striking appearance.
