How it works

 

Our company’s aim is to open up even more possibilities to anglers with the excellence of its products.

In contrast to land-dwelling vertebrates whose sense of smell and taste is specialised for detecting volatile substances, fish react in particular to water-soluble substances. The odours dissolved in water bind to chemoreceptors in the sensory cells of the olfactory epithelium – the “fish nose”. Evolution has produced a matching receptor for every chemical substance vital for the survival of a fish. The receptor is only activated when the molecule is a perfect fit for the receptor’s binding pocket. This is similar to a key fitting only one lock.

If the concentration of the substance in the environment of a fish is high enough, as many receptors of a nerve cell are activated as necessary to conduct an electrical signal to the superordinate brain structure. In the brain, this signal triggers a type of behaviour matching the substance. For example, there are substances triggering a flight response or those which signal to the fish that a sexual partner is ready to mate.

Of all their senses, most fish species primarily use their sense of smell to find food. Even mainly visually-oriented hunters – such as different species of tuna – probably detect their prey by its scent first. Fish are particularly attracted to free amino acids (the individual building blocks of proteins). This is no coincidence, as amino acids have physical-chemical properties ideally suited for detection in water: They are highly water-soluble, small and an elementary building block of all life forms (also of potential prey). They can already function as a lure in a concentration of only 0.1 nmol/l (in comparison: to obtain the same number of sugar molecules in one litre of water, one would need merely [ 0.000034 milligrams of sugar.) Amino acids are thus the most significant class of attractants, whereas other substances such as fats or intact proteins play a minimal role since they are not easily soluble and/or due to their size.

However, the greatest attractant effect can be achieved when the most potent amino acids are mixed in certain proportions.

Existing lures are either available in the form of oil, brushable liquid, paste or solid. Studies have shown that 80 % of a brushed on attractant is washed off at the moment when the bait is thrown and hits the water. Lures in the form of pastes or solids are problematic, since they either dissolve too quickly, and as a result cannot be used for spoon-baiting, for example, or are too firm and release their attractants only very slowly – with the correspondingly weak luring effect.

The makers of Blutbombette have been working on the development of a long-lasting and highly potent baiting system. To this end, we have combined decades-long scientific research on the olfactory system of fish with the latest manufacturing technologies for medicinal products. Just as in modern medicines, the Blutbombette releases substances over a longer period of time. The bait tablets are made in such a way that they withstand mechanical pressure for a long time and nevertheless effuse the attractant continually in large amounts.
