Heres a little bit of information for any of you guys who are thinking of taking on a porbeagle shark.
The porbeagle shark (lamna nasus) is one of the sharks in the family known as the mackeral sharks, this family includes the great white and the mako shark amongst others. The porbeagle is warm blooded in that it can maintain its blood temperature at a point several degrees higher than its surrounding water this allows its muscles to work with much greater efficiency and allows for great bursts of speed, (interestingly one of the few other fish capable of this is also the great white shark). although they are not known for jumping clear of the water when hooked there apparently have been cases of them breaching when chasing prey items(once again similar to the white shark).The current IGFA record stands at 507lbs caught off Scotland (although these sharks may grow much larger and weights up to 900lbs have and lengths of around 13 ft are considered about maximum) and there have been 2 recorded unprovoked attacks (both on divers,both nonfatal) on humans.
It may make you think twice when your quarry may be almost as long as your yak and weigh three times what you do, to me thats one hell of a step up from a tope no matter how large.
On a slightly different plane, as the weather warms up we should be getting the usual occasional sitings of a great white in our waters.Although these is no recorded evidence that these sharks do inhabit the waters around Britain it may interest you to know that the usual excuse of the water being too cold for them may not hold true in that the winter water temperatures in the mediterranean where they are definitely present can be several degrees lower than the summer temperatures of the waters off the southern coast of Britain. There has also been put forward the idea that white sharks may be following the increasingly large number of basking sharks that are appearing off our coasts and feeding upon these.
Anyone fancy a pop at one of them! white shark fishing on a kayak the ultimate adrenalin sport!
