Essential oils are a fragrant mixture of liquid volatile substances derived from natural plant material. Essential oils have antioxidant and immune-stimulating properties. Separate essential oils (for example, anise) stimulate digestion. Essential oils are poorly soluble in water, so for their effective work in the carp baits they must be emulsified.
Natural essential oils for fishing
It is not accidental that in the manufacture of boilies essential oils (however, like any other liquid aromatic additives) are recommended to be added to the eggs. The egg yolk contains a large amount of lecithin, which is one of the best natural emulsifiers. Essential oils can be successfully used in the composition of self-made boosters on a glycerin base, since glycerin also has good emulsifying properties.
There is a hypothesis that some essential oils (or mixtures thereof), due to the similarity of their molecular structure to natural compounds, can effectively stimulate carp receptors, triggering the inclusion of food search mechanisms. In my experience, black pepper oils and asafetida are most effective.
Emulsions based on fish fats and vegetable oils
Fish oils, rich in unsaturated fatty acids, are a very powerful means of attracting carp. In addition, fish oil is well distributed in various layers of water (up to its surface), quickly and actively attracting fish to the lactated area. The most effective (both alone and in combination with each other) are salmon and halibut fats, as well as cod liver oil.
In cold water, the efficiency of the fat work is significantly reduced due to the fact that under the influence of a low temperature they thicken and are very poor or completely not spread in the water. To solve this problem, you need to create a water-fat emulsion. Emulsion is a small particle of one fluid, evenly distributed in another. Typical example of an emulsion is conventional milk.
Under normal conditions, fat and water do not mix. To produce a water-fat emulsion, we need a special substance called emulsifier. There are a large number of different emulsifiers, including those produced by companies specializing in carp nutrition (for example Nutrabaits). I personally use as an emulsifier xanthenes gum, obtained by fermenting glucose or sucrose bacteria Xanthomonas campestris. And although xanthenes gum is a thickener rather than an emulsifier, for our purposes it is quite suitable, and besides it is harmless and allowed to be used as a part of human products.
Production of emulsion
The sequence of manufacturing the emulsion is as follows. To a teaspoon of xanthenes gum add 20 grams of fish oil and 20 grams of water. Stir the components thoroughly with a fork until a uniform mixture is obtained.
Add a teaspoon of dry dye (or 8-10 grams of liquid) and mix again thoroughly. To the resulting colored mixture add 460 grams of water, 20 drops of black pepper essential oil, 5 grams of flavor for boilers (the same as used for boilers), one-two drops of butyric acid and again thoroughly mix. In a similar way, it is possible to prepare emulsions from such strong attractants as flax and hemp oils, as well as from odorous unrefined sunflower oil.
Natural extracts of plant and animal origin
The fish lives in water. Water is one of the best solvents of various chemicals, so fish are forced to live in a chemical solution with variable properties. The whole life of fish takes place under conditions of a strong chemical "background". If the fish did not learn to selectively evaluate the chemical signals surrounding them, they could not, for example, look for food by its smell, in fact, a chemical signal from water-soluble food components, among the background signals inherent in any water body. Therefore, carp receptors possess considerable selectivity with respect to various chemical compounds. Natural attractants, due to their specific molecular structure, are very well detected by the carp chemoreceptor system.
Therefore, such substances are very effective in almost any conditions of catching. In addition, when using natural extracts from natural raw materials (in contrast to chemical attractants). Practically there is no danger to exceed the necessary dosage, thus turning attraction into repulsion.
Among the most effective natural extracts are extracts from mollusks and crustaceans, internal organs of animals (for example, the liver), grains and nuts. The most famous and widely used natural extract is corn extract, known among carpets as corn steep liquor. Natural extracts can be included in the composition of boilies (adding them to the liquid base), as well as in the composition of boosters. In addition, natural extracts can be used to impregnate the nozzle, fermented and welded cereals, pellets, as well as kneading bait.
Liquid attractants of chemical origin
Liquid attractants based on artificially synthesized substances, both in pure form and in combination with natural attractants under certain conditions, can have very high efficiency in attracting the attention of fish. The most effective among this class of attractants, perhaps, are amino acid complexes.
Amino acid complexes
Free amino acids belong to the class of substances to which the chemoreceptor carp system reacts most strongly. Therefore, carp easily detects them from a fairly long distance, where their concentration in the water is extremely low. Therefore, specially selected amino acid complexes can serve as fast and efficiently attracting carp to the zone of catching attractants.
At the same time, when exposed to oxygen, amino acids quickly undergo chemical changes, so I would not recommend including them in the boilers at the stage of their manufacture. In my experience, much more effect can be achieved by impregnating the amine complexes of bait and nozzles immediately before their use.
Liquid amino acid complexes should be stored correctly. If you opened the bottle and poured some of the liquid out of it, before tightening the lid, squeeze the container in such a way that the liquid approaches the cutoff of its neck and then tighten the lid.
This way you remove unnecessary air from the tank and slow the chemical changes in its contents. Try to take with you just as much liquid amino acids as you plan to use on the pond. It is very convenient to use disposable syringes of the appropriate volume for their transportation without air access, leaving their main stock to be stored in a cool dark place.
On fishing, do not allow the presence of liquid amino acids (as, indeed, any other liquid attractants) under direct sunlight. Try to keep all the fluids in the shade, or even better in a special thermos bottle.
Liquid amino complexes can serve as a good addition to the composition of self-made boosters (it is also desirable to add them in the last turn, just before use).
Oleic acid belongs to the group of fatty acids, in relation to which the chemoreceptor system of carp is very sensitive. I do not think that someone will come to think of the smell of butyric acid as pleasant, but carp is able to detect it, dissolved in water in scanty concentrations.
In addition, butyric acid, when included in the bait, lowers its pH, and carp is known to feel very well any changes in the acidity of its environment. In my experience, bait with oleic acid is most effective in water bodies whose pH is shifted to the alkaline side.
However, use of butyric acid should be very careful. First, follow the recommended dosage. Secondly, when making boiled boilies, do not add oily acid directly to the eggs, otherwise they will curdle.
First, dilute the acid in any liquid (for example, in CSL or just in water) and only then add it to the eggs. Try not to work with butyric acid in the apartment and store the vial with it in any sealed container (at least in a bag with a clasp). Otherwise, its strong and unpleasant smell can ruin your home's life.
Butyric acid can be used not only in boilers it can be included in the composition of boosters and liquids for mixing loose baits.
Betaine - a natural substance that occurs in animals and plants was found in the juice of sugar beet Beta vulgarism in 1866, from where it got its name. Betaine is perhaps the most famous and often used for catching a carp attractant.
Liquid betaine is much more convenient to use than powder, because the liquid is easier to distribute evenly throughout the volume of bait on the carp. And if we are talking about the inclusion of betaine in the composition of self-made boosters, then the advantages of the liquid form of this substance are beyond doubt.
Betaine is not only a very effective attractant, but also a stimulant to carp fish's appetite. Like many other attractants, it shows the best results in a certain concentration. At the same time, a lower dosage reduces the attracting ability of betaine, and its excessive amount can deter fish. Therefore, when working with attractants of chemical nature it is always better to undercharge than to pour. The normal dosage of liquid betaine is 20-30 grams per kilogram of the base mixture for boilies or kilograms of any kind of bait.
