It's been many years since I have margin fished for carp, and I mean many years. But I've caught some of the biggest carp in my life this way. Not in this country either, but carp are carp and what I found out may benefit you.
Big Rik is dead right about solutude and quietness. If there are people walking around and making a noise, forget it. I used to margin fish a lake of about 3 acres with a dam wall at one end. I was the only person allowed to fish there and this arrangement lasted for 3 years until the owner sold the property.
First thing, fish into the wind. You want the wind lapping at your feet as it were.
Secondly, keep out of sight and keep low. In those days I didn't possess bite alarms. I just put the rod in two rests with a coil of silver paper from a cigarette packet around the line between but ring and reel.
All I used for bait was either sweetcorn or bread. Sometimes the bread was fished as crust, floating. Sometimes it was fished as flake - sunk. The owner used to feed the ducks with bread.
Now here is something you may not believe but the owner did not scare the carp at all. I reckon those carp would have taken bread out of her hand. I scared them though.
The remnants of the floating bread used to float down to the downwind shore of the lake, and thats where I fished for the big carp. There were about 6 carp in there over 30 lbs. I caught two of them twice in the 3 years I fished there.
Taking the crust off the surface was the most exciting part of this sort of fishing - right under your rod point with the crust on the hook being located right at the edge of the bank.
Another surprising thing that people will not beleieve is that the carp ALWAYS patrolled the margins in a anti-clockwise direction.
This was the Southern Hemisphere of course. Many people tell me that carp in England patrol in a clockwise direction.
I do seem to remember that this was the case in the 60s when I fished for carp here.
I would love to fish for carp like this again, but I fear on most waters these days, there are just too many other anglers around to make it possible.
Come to think of it I should have done a Chris Yates, but instead of dressing up like a scarecrow, I should have appeared on the side of the water in drag!!
