YUM Biological Gamefish Attractant


(Monday, July 28,1997 - Lafayette, LA) YUM®; is a newly discovered lure scent that is a true fish attractant. It was designed with biological ingredients that stimulate the aggressive attack instincts of gamefish. It was formulated to help the sport fishermen catch more and quality gamefish.

YUM® was developed through the personal research of Dr. Loren Hill, Head of the Zoology Department at the University of Oklahoma, in conjunction with the laboratories of Benchmark Chemicals, LLC in Lafayette, Louisiana. This latest discovery, involves the use of shad and minnow hormones as an attractant. These biological catalysts and enzymes were found when the shad and minnows become frightened or injured, and release their chemical alarm into their surrounding fishing waters which stimulated aggressive behavior. YUM® activates the feeding frenzy of predator gamefish. Not only will fish strike more often, but harder, and hold on longer.

The natural oil spray system is credited to Benchmark Chemical's extensive research and blending of the finest oils and scents nature has to offer. YUM® in addition to an attractant, also provides dominate odor masking capabilities. Humans give off negative odors or scents to gamefish. This negative aroma is created by the chemical L-Serine, which all humans produce from skin oils. Both YUM® Lure Spray and Hand Balm have the capabilities to mask or cover this negative smell, as well as, other negative odors such as gasoline, suntan lotion, tobacco smoke, etc. The L-Serine and other odors are eliminated, therefore, allowing the attractant to be fully released to assure the fishermen the best of both processes. The following is a summary of Dr. Hill's discovery.

Dr. Loren Hill's Report in Summary:
Predator gamefish like bass, walleye, northern pike, musky, crappie, etc., have an excellent sense of smell because of two openings on each nostril which water circulates through them to detect odors. A fish's sense of smell, Chemoreceptor system, is much more sensitive than a human's sense of smell. One reason is because water is 800 times more dense than air and has a tendency to dissolve chemicals and keep them suspended for some time. Their receptor organs, nose as you might say, picks up these odors that linger in water much longer and don't fade away as rapidly like those smells that humans sense in air. These organs are constantly in use, detecting smells not only for food sourcing, but also for their own protection.

This is why YUM® is different! It is both a cover for negative odors, which alarms the gamefish for protective reason like most other scents, but YUM® also has added natural active enzymes that trigger the feeding instincts of the predator gamefish found through laboratory research.

Laboratory studies on a variety of species were performed in several experimental tanks. Perimeters were kept constant for a period of time to condition the gamefish. Their food source varied somewhat with the species until all the fish were conditioned to certain feeding habits. Competition for food became apparent. This is when experiments began, conducted with a variety of lures with a variety of odors/scents, to evaluate their reaction, (negative, neutral or positive). The following will show the results.

NEGATIVE

  • L-Serine (human skin oil)
  • Nicotine
  • Petroleum, including gas and motor oil
  • Suntan Lotions
  • Bug Repellents
  • Amino Acids - 5 found in human development
  • NEUTRAL

  • Anise Oil
  • Natural vegetation (grass and leaves)
  • Soda Pop
  • Fruit Juices
  • Human Saliva
  • Amino Acids - 2 found in nature
  • POSITIVE

  • YUM® exclusive enzyme
  • YUM® exclusive enzyme
  • YUM® exclusive enzyme
  • YUM® exclusive enzyme
  • YUM® exclusive enzyme
  • YUM® exclusive enzyme
  • The test results showed that in every case, YUM® was very positive to the gamefish's sense of smell and also triggered aggressive behavior.

    The experimental research conducted, verified that all the gamefish reacted the same to all the situations presented to them. The negative smell track generators were especially noticeable with the human skin oils (L-Serine) and amino acids. Anise oil surprisingly had no effect on any of the experiments as well as some natural amino acids. However, the positive enzymes discovered recently showed very positive and even aggressive behavior from the gamefish.

    The odor coming off human hands (L-Serine, human skin oil) was distinctly repulsive to the gamefish. The research verified that not only would the fish not strike, but they would turn away. All human skin oils contains a certain amount of L-Serine and may even reach higher levels with certain individuals. Technically, L-Serine falls into the category of compounds known as amino acids. This component has high solubility i water which reinforces the problem, because fish thus have the opportunity, because of dispersion, to detect these chemicals. Such negative chemicals permeate even fishing line, which is when the negative smell tracks become a serious problem to the fisherman.

    During this testing, fishing line was exposed to different odors which were absorbed in the molecular matrix of the line when stored in the same area of the chemicals. These smell tracks were detected by the fish and negative results were recorded. Within the experimental tanks, fish would not approach a lure because of this negative contaminated line. Humans with high L-Serine levels were asked to run the line through their fingers/hands while filling the reel with fresh new fishing line. These individuals inadvertently transferred negative chemical odors to the line. This fishing line stopped the fish in approaching a lure in the experimental tanks.

    Experiments were conducted by introducing artificial lures and natural live baits. The conditioned gamefish responded by striking both stimuli, favoring the live bait. Negative smell tracks were then applied to both. In every case, the fish rejected the contaminated lures and live bait after approaching them and then turning away. When presented, either artificial or natural bait scented with neutrality, the gamefish would approach the strike the bait. However, the artificial baits were frequently rejected following the strike, whereas the fish retained the natural baits when captured. The positive components, recently discovered, were distinctly different in reference to the behavioral confirmation of gamefish compared to all other ingredients. These components stimulated the aggressive attack instincts from both artificial and natural baits. The fish did not reject the baits, whether artificial or natural.

    YUM® is a true attractant and a scent all in one! This is why YUM® Lure Spray and Hand Balm are essential tools for the fisherman's tackle box.
