Distribution
Porbeagle Sharks are found in the cold and temperate marine waters of the North Atlantic and Southern Hemisphere. They are known to migrate seasonally, moving towards the poles in the summer and towards the equator in the winter.
Habitats
Porbeagle Sharks typically inhabit offshore waters. They can be found at depths of up to 700m and prefer water temperatures between 1 and 18 degrees Celsius.
When and Where to See
Porbeagle Sharks are most commonly seen in the warmer months of the year during their seasonal migration. They are most active during the day.
Best Fishing Locations
While Porbeagle Sharks can be found in many regions, some of the most popular fishing locations include the North Sea, the waters around Iceland and Newfoundland, and the Bay of Biscay.
How to Catch
The best bait for Porbeagle Sharks includes small fish like mackerel, herring, and squids. Popular fishing techniques include trolling and chumming. The best time to fish is during daytime, particularly in spring and summer.
Identification Guide
Porbeagle Sharks are dark bluish-gray to brown on their dorsal (top) side, and white on their ventral (bottom) side. They have a pointed snout, large pectoral fins, and a crescent-shaped tail. Compared to similar species, Porbeagle Sharks have a more streamlined body and lack the prominent dorsal ‘caudal keel’ found in other mackerel sharks.
Culinary
Porbeagle Shark meat is often used in fish and chips and is considered high-quality. It has a mild, naturally sweet taste. Nutritional value includes a good source of protein, vitamin B12, and healthy fats. It can be cooked in many ways, including grilling, broiling, and frying.
Additional Information
Porbeagle Sharks are known for their playful behavior, often seen leaping out of the water. They are solitary animals but can be seen in small groups during feeding or mating. They are also known to face several threats including overfishing and bycatch. They have been commercially fished since the early 20th century.
