The Porbeagle Shark is a blue-grey colour on top with a white underneath and a white patch on the trailing edge of the first dorsal fin. It has a crescent shaped tail with a secondary keel that cuts through the water during the side to side swimming motion the shark makes. Adults can reach a size of up to 12 feet, and have an average life expectancy of 30 to 40 years. They have relatively large eyes, and teeth in the moderately sized mouth are similar in both the upper and lower jaw being smooth-edged with lateral denticles. The Porbeagle has a heat regulating mechanism that raises the body temperature 2.7 to 8.3 degrees Celsius above the surrounding water temperature. This allows the shark to operate more efficiently in the cooler waters it inhabits. Unlike many other sharks the Porbeagle must swim at all times in order to breathe.
Female porbeagles do not reach sexual maturity until 12 years of age or older, while the males are mature around 7 years old.

The Porbeagle shark is commonly found in pelagic and littoral zones and inhabits water down to a depth of 370 metres (1,120 feet). It is most commonly found on continental shelves or inshore. It prefers cool waters and is usually found in temperatures below 14 degrees Celsius. Porbeagles occur on both sides of the Atlantic and in the south Pacific and Indian Oceans. In the western North Atlantic it can be found from Raleigh, Newfoundland at its northernmost range to the Gulf of St. Lawrence, the Scotian Shelf, the Bay of Fundy and the Gulf of Maine to New Jersey and perhaps to South Carolina. Off Nova Scotia the Porbeagle is generally found in waters less than 14 degrees Celsius.
Predominantly a predator, the Porbeagle feeds mainly upon pelagic fishes such as Herring, Pollock and Mackerel. However they also eat Cod, Redfish, Haddock, squid and shellfish, and have also been known to take gulls and other seabirds.
Tackle and Methods
There are several different classes of rods available for Porbeagle fishing, based on the line-class system. Rods with line-class ratings of 30lb class or below are what some describe as light-line fishing. However a 50lb class rod may be more suitable, this will land most fish that you will generally encounter within a reasonable time.
There are a lot of good quality rods to choose from in the 50lb line-class bracket with most of the large tackle manufacturers such as Penn, Daiwa and Shimano making rods to suit most bait fishing applications. Rods with a fibreglass/carbon mix are generally considered a good material in the right ratio, as this provides both strength and lightness. Rod lengths of about 7.5 – 8 feet are about the right length of rod to use.
Reels can also be found from all the leading major manufacturers such as Penn and Shimano etc, reels such as the Penn Senator size 6/0, Daiwa Sealine size 450 to 600, Shimano Tiagra size 4/0 have stood the test of time and have suitable line capacities of about 500 yards of 50lb line.
Monofilament lines are the type to use for porbeagle shark fishing. A good quality line should be used. Most fishing applications will require the use of 50 & 80lb line class. However, some anglers like the challenge of light line fishing in the 12, 16, 20 & 30lb classes.
Hooks in the 8/0, 10/0 and 12/0 sizes are the ones most applicable for porbeagle shark fishing.
The rubbing trace should usually be of monofilament line of approximately 250-300lb breaking strain, and be around 30 feet in length, and a biting trace of a 7 strand, kink resistant wire of around 5 feet of approximately 3mm diameter.
