Blue sharks normally arrive off the Scillies in good numbers around early July, staying on well into September as they don't appear
to like sea temperatures below around 16 degree's celcius. But they will be well spread about the place and will need to be attracted
to the boat to be in with any real chance of success. They key to this is rubby dubby. The more chum going in the better. Its vital to
to get a good, well fed, un-broken slick going, both for the fish as well as the birds. Blue sharks are what is known as pelagic
fish which means they spend their lives in the upper layers of the water as opposed to feeding at the bottom. So other than food,
there are no features likely to concentrate them, hence the need to draw as many as possible in to the boat and of course the baits
which are waiting for them in the slick.
Rubby dubby as a concept is simple. In practise however it can be anything but. A lot of thinking has gone in to the most
productive way of setting up a slick. What you don't want is particles of uniform size as these will all act in the same way.
Equally, liquids such as blood and fish oil on their own are not much use as they tend to stay close to the surface. The secret
is a mix of all these things. Smashed up mackerel left to soften for a few days are one ingredient. Fresh mackerel put through a
chum grinder adds another dimension. Fish oil and fish juices are also used along with mashed up pollack livers which are good
for drawing in the birds. Some of the birders also bring along bread soaked in fish oil. A word of warning though. The smell
of some of this stuff coupled to the boat wallowing on a long beam on drift is not for the feint hearted, and there were victims
on every trip.
A good rubby dubby slick is a long three dimensional trail looking to intercept fish at whatever level they may be feeding at,
so the baits must also be put out with this in mind. Mackerel flappers on 12/0 hooks to 16 feet of heavy wire form the business end
of the tackle. Circle hooks are preferred as these lead to more mouth hooking of fish and obviously, less potential for actual or
stress related damage. What happens is that the baits are suspended under balloons at different depths, usually between 60 and 20
feet, with the deepest baits furthest from the boat. Sharks moving up the slick can do so at any depth. But what they invariably
do is start moving up in the water column as they get near to the boat, as that is where the chum concentration will lead them,
back to source which is one of maybe six mesh bags suspended just under the waters surface.
All tackle used on these trips, including the mackerel rods, is supplied on the boats. But to avoid any confusion as to which
rod might be allocated to who after either Joe or Alec has set them out, it is important first to ask. Better still, take your
own tackle. The gear they provide on board is all quality stuff. Most of the reels were Shimano TLD25's and the rods 30 pound
class from Conoflex. I took along my Shimano Exage 4 piece travel rod and TLD25 which happened to have 40 pound bs braid on it
from previous skate fishing trips. Reels on the boat tend to come loaded with 50 pounds mono which is understandable when you
consider that anyone can come along, including novices, and use them. But when bringing your own tackle, you can scale down
much further than any of this. After all, a blue shark is not that far removed from being a big blue tope, and 60 pound tope
are regularly boated on light uptide outfits.
The average size, and indeed average numbers of blue sharks taken these days has declined markedly in recent times, in the main
due to increased commercial pressure. When I last fished the Scillies in the early 1980's we had 17 sharks on one day. Now half a
dozen would be a respectable haul for a full day afloat, with fish in the 30 to 60 pound bracket being the norm. Bigger fish are
still on the cards, with both skippers having had ton up fish recently (Alec 120 lbs & Joe 117 lbs). But pressure from both UK as
well as Spanish commercial boats is taking its toll, particularly the practise of attaching baited hooks to dan buoys used to mark
or support the ends of nets. There is talk of bringing in a range of protective legislation for sharks generally as they are
officially listed amongst the most endangered animals on the planet, the main UK pressure group being SOS (Save Our Sharks)

Shark fishing most definitely is a waiting game. And the longer you wait, the better your chances of success. So don't be
surprised to see all the evenings action compressed into the last hour. Equally, don't be too surprised either by an early fish
that enters the slick close to the boat as soon as it is set up. I had one with Alec well inside the first hour. At the other
extreme, we had one take just as the lines were coming in ready to head for home. So having other people on board with different
interests to you can make for a welcome distraction, particularly when they are so enthusiastic and willing to explain at great
length everything you could ever want to know about ocean going sea birds. To me, offshore sea birds come in three types - gulls,
big black things, and little black things. But now I can put real names to a few such as storm petrels, shearwaters and skua's.
But when the really tasty stuff starts feeding in the slick, of which there were several examples, I was totally lost.

Birds and sharks are not the only animals to enter the slick and track it back to the boat. Chum slicks can attract good
numbers of garfish which make for good sport on a light float rig. Sunfish, turtles, whales and dolphins are also regularly seen,
though possibly not attracted by the slick. We had a sunfish come by on one of the evenings. On top of this, if the tide isn't too
big and the wind isn't pushing the boat along too quickly, putting baits down on the bottom can be a good way of occupying yourself
while waiting for the sharks. Depending on the type of ground obviously, pollack, ling, spurdog, whiting, haddock and even megrims
have been brought aboard. If you are intent on giving the bottom fishing a try, load up with braid as you are likely to be fishing
in at least 90 metres of water.
Both Joe and Alec are heavily involved in shark tagging schemes, interestingly, run by different organisations. Alec works
in with the long established Shark Angling Club of Great Britain, whereas Joe tags for Dr. Ken Collins at the Southampton Oceanographic
Centre who has taken over where Sue & Geri Drake left off when they moved to Africa recently. Joe brought up a positional distribution
of recovered tags on his GPS plotter which, when presented like this, very clearly shows a pattern. Most tags are recovered by
commercial boats, sometimes working hundreds of miles from base. This recapture pattern suggests a migration back down to the Biscay
area at the end of the summer, then across the Atlantic to the eastern seaboard of the United States. Shark data recording has also
shown that 90% of all blue sharks taken in UK waters are female fish, with the majority of the males over on the other side of the
pond along the American coast, hence the attraction in UK fish making the long trip. This is supported by the recapture of one of
Alec's fish off the coast of Boston USA.

Both have boards on the harbour jetty giving details of proposed pelagic trips which you can just turn up
for on the day. But if it's full day trips that are required, these can be arranged providing there is a full
party to take the boat. Alternatively, try Martin Jenkins Tel. 01720 422251 who probably has more all day availability.
