It will probably come as a surprise to many fishermen that fish alternate frequently between one feeding mode and another, in order to best profit from various food opportunities available in the aquatic environment even within a short time period and this can change many times even over an hour or 24 hour period. The way fish feed is key to how best to tempt them in order to get a hook in their mouth and catch them, but few anglers actually give this immensely important subject the attention it demands. But the good news is that you can induce many fish feeding modes simply and easily in order to catch more fish purely by exploiting what comes naturally to them...

If you ever fished a match using tiny hooks for bloodworm or jokers as bait, you will know how powerful these fish catching baits are. One of the best feeding triggers for carp and one of the most abundant amino acids found in mature carp tissues is alanine which also happens to be found in abundance in blood worms and jokers. Fish instinctively feed in the most energy efficient way depending on the food supply available and how and where it is located and how spread out or dense or large or small the food items are.

You may have watched koi or goldfish sucking algae off the sides of a pond. But carp can also feed by filtering tiny items from the water, while moving and even while stationary. The position and concentrations of natural foods like algae and crustaceans called zooplankton or daphnia fluctuate depending on sunlight angle and intensity, temperature and water mineral and oxygen concentrations among other time and seasonal variations. The successful use of very fine ground baits is one way to induce the filter feeding type of modes whilst on the way to the angler inducing feeding on larger food items such as boilies for instance.

Because carp gain their energy predominantly from amino acids and even their tissue lipids are composed of them primarily rather than from oils or carbohydrates, it makes great sense to leverage them in inducing filter feeding to get them in an excited state! In this way you can know the fish can truly positively assess your hook baits and free baits in advance of physically sampling them, by the particles and substances in solution and in suspension in the water columns coming from your baits. In doing filter feeding mode of feeding, carp will taste what they are filtering using taste buds in their pharyngeal cavity, and can feed like this while moving or stationary and on difficult pressured waters stationary filter feeding on bait substances in suspension etc is very common.

Filter feeding is very interesting because fish like carp can gain masses of nutrients to promote their growth in safe ways without eating your baits. But they can also derive nutrients from your baits in suspension and in solution as they leach out amino acids, nucleic acids, oils and slats for instance, without actually eating your baits. So it makes sense to drive fish into a feeding frenzy mode as far as possible by inciting this natural feeding mode.

It is natural for fish like bream, roach, carp, tench, barbel, and even bass and trout, to filter feed at times by capturing various sized food particles within their branchial sieves. However there this sieving can be adjusted in order to capture patches of fine particles or to capture larger single items and the characteristic speed of this feeding can vary between species. In the case of carp which are termed slow suction feeders, although they can suck up finer particles from one head length away from it at surprisingly high velocities indeed.

The chemical senses of carp are often mentioned in relation to bait, but the role of the carp lateral line is far less mentioned. The electrical sensitivity of this area in food detection is often severely over-looked by anglers seeking to improve their baits and it is so finely tuned it can detect the tiny movements of zooplankton. As carp are primarily filter feeders using slower suction motions compared to other fish, it makes sense to exploit this by using fine ground baits and smaller hook baits too!

Smaller food items can naturally be passed to the throat teeth in mouthfuls without any problem and of course the more energy efficient the food delivery system is the better. It can often be the case that small baits are the preferred choice of more experienced big fish anglers because they can see the benefits of smaller food items in regards how fish feed on such baits and also their more natural weight, size and movement in water when combined with a correctly balanced hook rig. I find boilies in the 6 to 8 millimetre size excellent for bigger more wary fish even with huge mouths!

If you exploit the various filter feeding modes of fish using various grades of ingredients both soluble and insoluble in your ground baits you can certainly induce far more intense and suitable feeding for hooking wary big carp. You might recall the fact that fish are lateral lines are tuned to feel the movements of live foods like maggots and sound is important in ground bait effectiveness, but smaller hook baits are well recommended in conjunction with this. With carp one thing is for sure and that is when you leverage their mode of feeding or preferably specifically induce particular modes of intense feeding, you can vastly improve your catches all year round and all you need to know is a bit more about effective bait use and ingredients manipulation...
