And this one too!
the spot and bubbling up and says
quite rightly that they can’t be hitting
the bottom so quickly, so why the
bubbles?
I’ve made it sort of a study of mine
over the years since fishing somewhere that was quite silty some time
ago, and where there always seemed
to be bubbles coming up in certain
areas. I found myself wasting quite a
lot of time fishing some places where
it was just gas escaping from rotting
vegetation, or some types of bottom
that seem to give off bubbles. Then
probably eight or ten years ago now, I
started using maggots a lot, fishing
for bubblers became the norm, and
watching fish head and shouldering
and bubbling up over the spot. I came
to lots of conclusions about bubbles
and which were feeding fish and
which were fish that were using their
swim bladders effectively. I think this
is what you’re seeing here, and a lot of
people won’t know about swim bladders and what they do exactly. I think
most people know that they’ve got
them, but this is how a swim bladder
works…
For a fish to sit motionless at a certain depth without continually having
to flap its tail to keep at that point or
move its fins, it uses its swim bladder
either to inflate or deflate. I’ll ask a
question here too – just imagine this
scenario… In a deep pit, if a fish
wants to go down close to the bottom
and be comfortable just sitting down
there without having to continually
keep righting itself, do you think it
would need more air in the swim
bladder or less? I guess most of you
out there will say, well it needs less;
you would take air out of the swim
bladder, which would enable the fish
to sink down. You would think it
would be less buoyant and it would
go down into the depths, but that’s
where you’d be wrong, because in
fact in deep water they need more air
in the swim bladder. This is because
of the pressure of the water.
Imagine a fish 15-20ft down;
there’s a lot of water pressure pushing that fish down. It’s got all that
water on top of it forcing it down, so
what it needs is extra air in the swim
bladder to make it more buoyant to
compensate for the extra water pressure, and I guess that that’s what
you’re seeing. It’s fish that are feeding
down in deep water; they very often
have to come up and regulate the air
in the swim bladder. They’re taking
on more air, then they’re going down,
expelling a bit of air and getting the
right amount of air inside the body so
they’re the right buoyancy. They need
extra air the deeper the water is,
which is something that a lot of people reading this probably didn’t know,
but some people will do, as I’m not
the first one to write about it. I
remember an article that somebody
wrote a couple of years ago, and in
fact if I remember rightly quite a lot of
it was wrong. But I did read up about
swim bladders when I did biology as
an A-Level, funnily enough.
Ok, moving on quite quickly this
month, and I’ve been able to answer
the questions from personal experience… Mr Sargent wants to know
about using tigers and hemp, which
is a fantastic combination; a combination has probably caught more carp
than anything else in the country as
one particular bait. Obviously boilies
Over 25kgs of hemp.
