If I am after quality sized Carp and I know they patrol along a bank at certain times then I would just put a few freebies in the edge and wait for the carp to come along, keeping low and still and quiet.
But do your homework and find out where abouts the Carp feed and patrol by either asking a friend or finding out yourself.
If I am fishing a commercial that holds zillions of stunted Carp then I may be better using pellets nearer the surface once the temperatures start to rise.
NB: I don't fish commercials at all these days and the last time I fished a match on one was around twelve years ago so don't take what I've said about fishing them as gospel
If I am after Tench (once the temperatures start to rise) I often try laying a small bed of Tench groundbait (usually a groundbait containing either sweet molasses and/or blood), or a small bed of particles or chopped worm then wait for the Tench to arrive and give themselves away with their fine clouds of bubbles.
If I'm after Bream the same can apply but I have a bigger choice of groundbaits to choose from.
If I am after silvers then I feed little and often and start just off the bottom
Moving up in the water if they are competing for baits and moving down if bites are very slow.
NB: I often find that I can sometimes dictate the depth where a shoal of average sized roach is taking my bait by feeding a little more if I want them to feed on the bottom or reducing the feed slightly if I want them to be searching for sinking baits further up in the water.
In the winter months feeding 'little and often' may mean as little as just one or two maggots every couple of minutes but once the fish start to feed well then I adjust to suit the amount of fish I have feeding in front of me.
In the warmer months or if I am fishing a water with a larger stocking density then I can usually afford to feed a lot more.
Well that's a short potted guide but remember nothing is set in stone so it's worth finding how and where others on your venue catch their fish on the waggler Lol.
