Anyone that watches fish feeding on bait will understand why some fish are harder to catch than others. The manner in which some of them feed means that just getting a hook in their mouth is going to be difficult, unless they throw caution to the wind, go on a frenzied munch and make an uncharacteristic mistake.
It’s a basic fact that some of the trickiest fish to catch aren’t hard because they are cleverer than the others. I tend to think that most the time it’s just the way they feed because of the size and shape of their mouths and the angle at which the feed related to the lake bed.
Take this scenario for instance. A couple of the famous old carp on the Yateley complex would sometimes go very long periods of time without falling foul of an anglers trap but they both (Jumbo and Arfur Tail) had broadly similar shape bodies and mouths that largely account for the way they fed – in this with their lips consistently tight to the lake bed.
Now imagine putting a popup in front of a fish like that! No thanks…
If you’re using a pop up rig the bait is likely to be either shifted out the way as the carp snuffles along the lake bed browsing on food items or (as it’s likely to be at eye level) noticed it isn’t natural and ignored it. In the worst case scenario it’s possible that it may even unsettle the fish enough to make them very cagey! In which case they will feed even slower and more cautiously and then you’re really up the proverbial creek in terms of catching them!
Spodding in a mixture of small food items is extremely effective at holding fish on a spot for longer, as they feed harder and longer to clear up the freebies as the tasty little seeds and pulses settle into gaps in gravel or sink down into the silt a little bit. Just remember that using a bed of small baits only encourages the carp to feed with their mouths tight to the lake bed even more! This is really why, as a general rule, hookbaits fished right down on the lake bed will work better over beds of particle style baits.
